Description

The cotton intercropping Cotton Field under Drip Irrigation of Xinjiang jujube Cotton Population structure construction method

Technical field

The present invention relates to the cotton intercropping Cotton Field under Drip Irrigation of a kind of Xinjiang jujube cotton yield group structure construction method.

Background technology

The cotton intercropping of jujube is a kind of typical solid growth pattern, this pattern is in jujube tree field, particularly before jujube tree full bearing period or the larger jujube tree field intercropping cotton again of jujube tree line-spacing, this pattern takes into full account that the limb of jujube tree own is sparse, and blade is little, main root prosperity, belong to deep-rootedness economic tree, lateral root and fibrous root are distributed within the scope of underground 20～80cm soil layer more, thereby can absorb soil deep water and divide and nutrient, for interculture provides sufficient ground, underground growing space.Thereby this pattern not only can make full use of the natural resourcess such as soil, illumination, moisture, temperature, can also guarantee that peasant bears fruit in a large number and obtain before better benefit in jujube tree, increase farmers' income by intercropping cotton.

There is higher promotional value in the developing country that the cotton intercropping of jujube can meet jujube tree and the growth of cotton normal growth in " having a large population and a few land " and natural, ecological resource (mainly referring to light, heat, water, soil etc.) simultaneously, and in American-European developed regions, owing to there not being " having a large population and a few land " problem, add above-mentioned cropping pattern recruitment many, up to now, developed country has no the cotton interplanting mode of fruit, comprises the report of the cotton intercropping mode application of jujube.In less developed country (except China) cotton main producing region, although there is more serious " having a large population and a few land " problem, but owing to not carrying out relevant research work, lack corresponding management method, the cotton interplanting mode application of jujube also has no report, in a word, and except China, flourishing and less developed country is showed no the report of the cotton intercropping mode application of jujube, and the cotton intercropping cotton field cotton of certainly relevant jujube yielding Populations structure construction method is also without any documents and materials.

The cotton intercropping of jujube all has plantation in Xinjiang of China and interior ground (mainly referring to the provinces such as Shanxi, Hebei, Shandong, Henan, Shaanxi), but with Xinjiang cultivated area maximum, Xinjiang is approximately 3,500,000 mu of left and right at present, and compared with Xinjiang, in China, ground planting scale is less.The cotton intercropping of Xinjiang jujube region is mainly distributed in analysis in cotton fields in south Xinjiang main producing region, Xinjiang.

In China, promote the cotton intercropping culture method of jujube compared with Xinjiang early, but in relevant China, jujube cotton intercropping culture method in ground only has fragmentary report.The cotton intercropping culture method of Xinjiang of China jujube large scale application development time is more late, matching method research report is also less, and the method for open report has significantly applies mechanically nonoculture cotton field cultivation method, its cultivation method does not consider that intercropping cotton group structure builds pointedly, cause the cotton intercropping cotton of current Xinjiang jujube produce in group structure build generally unreasonablely, finally can not make full use of the natural, ecological resources such as local light, heat, water, soil.

Existing research shows: reasonably group structure is the key that crop obtains high yield, in nonoculture cotton field, relevant Cotton Population structure index research report is more, but the group structure construction method of system is also few, the cotton intercropping of jujube cotton field, particularly not report of the cotton intercropping Cotton Field under Drip Irrigation of jujube yielding Populations structure index research, in a word, the domestic documents and materials that there is no the cotton intercropping Cotton Field under Drip Irrigation of Xinjiang jujube cotton yield group structure construction method up to now; Considering to build rational group structure is one of key measure realizing the cotton intercropping cotton field cotton of Xinjiang jujube high yield, and the present invention, according to research in recent years and investigation result, proposes the cotton intercropping Cotton Field under Drip Irrigation of Xinjiang jujube cotton yield group structure construction method.

Select early kind of ripe property, the main cultivation cotton variety of more local nonoculture early 5 days conventionally, guarantees that under the cotton Intercropping of jujube, cotton reaches the term of opening bolls in 12-20 day in September, plant type is cartridge type, leaf inclination angle is little, lift on blade, and the few kind of foliation amount, and average monolithic leaf leaf area is no more than 40.5cm ², under Intercropping, flowering and boll-setting period net photosynthetic rate can reach 25-30umol/m ²s, the term of opening bolls also can normal blow-of-cottons in low temperature and less sunshine situation, after kind is determined, then expand numerous by the conventional expanding propagation method of cotton original seed to the kind of selecting, lint, selected, then wait to broadcast through after the assay was approved, before carry out germination test by the end of March, non-precision drilling cotton field germination rate at least reaches 80%, precision drilling cotton field seed must carry out look choosing, guarantees that germination rate should be higher than 90%, gets ready to plant and waits to broadcast;

Prepare in cotton field:

Cotton Soil basis: should select effective soil layer thickness 1m, physical features is smooth, when subterranean water level is the highest, must not be less than 1.0m, upper (the content of organic matter >=10.0g/kg in soil fertility level, full nitrogen > 0.6g/kg, alkali-hydrolyzable nitrogen > 40.0mg/kg, rapid available phosphorus > 10.0mg/kg, available potassium > 120.0mg/kg), topsoil total salt content < 0.3%, pH value 7-8, the good sandy loam of irrigation condition or light clay;

Irrigation before seeding: the winter irrigation time, between November first arrival December 20, prevents that the winter irrigation time from causing the generation of jujube tree freeze injury phenomenon excessively evening, or the spring irrigation time before March 15, complete, spend evening and can not guarantee cotton sowing in time, irrigation volume is 170m ³/ mu;

Use sufficient base fertilizer: intercropping cotton field base fertilizer chemical fertilizer kind and consumption: amount to pure N5kg, pure P ₂o ₅10kg, pure K ₂o5kg, micro-fertile kind and consumption: manganese sulphate 1.5kg/ mu, boron fertilizer 1kg/ mu, zinc sulphate 1kg/ mu, manure type and consumption: dregs of fat 100-120kg/ mu or the essentially identical fertilizer of other function;

Seedbed preparation: whole ground at the beginning of by the end of March-4 months, seedbed preparation, centered by " moisture in the soil " word, reaches " moisture in the soil, flat, loose, broken, clean, neat " six sign standards, should carry out the residual film on the field work of picking up clearly when on whole the ground.For prevent whole cause jujube tree mechanical damage or jujube tree root impaired, should select middle-size and small-size farm machinery operation, and guarantee that broken ground edge and jujube tree plantation row minimum distance are controlled at 55cm.

The anti-grass of chemistry: in conjunction with the whole ground weeding on jujube tree ground, the trefanocide 80ml of every mu of use 48% is watered 30kg, or Acetochlor 100ml, be watered 30kg, limit spray side drag (harrowing dark 8-10cm), makes medicament evenly mix with soil, to improve herbicidal effect, when spray medicine, should prevent that agricultural chemicals is sprayed onto on jujube tree;

Sowing:

When surface layer is 5cm, ground temperature is stabilized in temperature and starts sowing when more than 14 ℃, suitable date of seeding is April 5 one 12, for solving better the slow problem of the previous growth, take two films to cover, by taking plastic film mulch, fan the air, sow, the disposable sower completing of earthing completes seeding operation, cotton planting is walked to being north-south, with the nearest cotton row of jujube tree and jujube tree Planting Row Distance from being 65cm, and according to the width of the reserved intercropping cotton plantation in jujube tree field row, determine reserved intercropping row overlay film width and plant wide film web number (1 width or several films), conventionally base area film web is wide can be divided into 1.25 by sower, 1.45, 1.8, 2.0, five kinds of fabric width mulch film machines of 2.3m, the sower of above-mentioned five kinds of different fabric widths is available, thereby guarantee that the reserved actual planting area of row cotton of intercropping is substantially supporting with reserved row, guarantee that the fruit tree row cotton row distance nearest with it is moderate,

Cotton average row distance is 32.5cm, wide-narrow row planting mode, when several film plantations, its handing-over every trade distance is 55cm, different sowing distance between rows and hills differences, to reserve intercropping interline as boundary, far away apart from jujube tree plantation row, its spacing in the rows is larger, is 9.0cm apart from the capable nearest cotton planting distance between rows and hills of jujube tree plantation, is 12.5cm apart from the capable cotton planting distance between rows and hills farthest of jujube tree plantation, according to this conclusion, different cotton planting distance between rows and hills setting ranges are 9.0cm, guarantee that the two adjacent distance between rows and hills scopes of differing are 300-1000 plant/acre, and each row solid density is 16000-19500 plant/acre;

Sowing strictly accomplish to broadcast speed evenly, sow evenly unanimously with the degree of depth, arrive to the end limit, guarantee to broadcast full stand, sowing depth is 2.0cm, and mulch film and ground are close to, degree of tightness appropriateness, face is totally open and flat, and lighting surface is large, broadcasts row straight, firming is tight, the film limit 7-10cm that buries, and seeding down is even, plant cave and mulch film hole and do not misplace, hole rate is less than 3%, and precision drilling hole rate is slightly high, the depth is consistent, and earthing is even, and consolidation is tight;

1 of precision drilling every cave program request, every mu of seed consumption 1.7-2.1kg, the every cave program request of semi-accuracy seeding 1-2 grain, every mu of seed consumption 2.2-2.8kg;

After finishing kind, check in time a field emergence situation, find broadcast leakage, or have rotten son, rotten bud, fill the gaps with seedlings in time, stop two strains;

On sowing caudacoria, press a soil zone every 15m, prevent from meeting wind and start mulch film, as strong wind weather, look in time mould grave hole, in case strong wind is taken off film;

Irrigate breeding time:

Adopt drip irrigation, drip 13-16 the time of infertility, compared with nonoculture cotton field drip irrigation 2-3 time often, cotton field is at water dropper water on 20-June 5 May, and water stopping time is in August 25 and September 12, a water early 5-7 days, tail water 5-10 days in evening, interval 4-7 days drips once, single filling amount 20-25m ³/ mu, the cotton field of a late water dropper water water water consumption and last water can increase to 27-30m ³/ mu, the about 260-350m of the amount of dripping in the time of infertility ³/ mu, firmly prevents later stage " arid is forced ripe " phenomenon, guarantees that blow-of-cottons are in time with smooth and easy;

Reasonable arrangement is coordinated stripping field jujube tree and cotton irrigation time: the water feature that needs of jujube tree and cotton has notable difference, intercropping cotton field jujube tree early and middle ten days in April must be filled with the front water of bud, poured water once every 18-22 days later, and intercropping cotton May does not need to pour water before upper, July, cotton and jujube tree all needed water in a large number, August, the colored bell water demand of cotton was larger, and jujube tree irrigation requirement is relatively little, thereby the cotton existing water sync period that needs of jujube, conflict the phase again, while needing water synchronous, can irrigate simultaneously, but while occurring that water has conflict, must irrigate jujube tree or cotton separately, now should be specifically noted that and prevent string filling,

Topdress:

Topdressing in intercropping cotton field is all chemical fertilizer, its kind and consumption: amount to pure N20-25kg, pure P ₂o ₅4-5kg, pure K ₂o1.5-2.0kg, in conjunction with drip irrigation, carries out " water one fertilizer " and topdresses, and chases after the principle strengthening gradually by flower bud phase, initial bloom stage, Sheng bell phase into amount, and each phase proportion is about 1.5:2.5:6.0, and focuses on foliar applied fertilizer;

Foliar applied fertilizer: the most frequently used foliage fertilizer is micro-fertilizer such as urea, potassium dihydrogen phosphate and zinc sulphate, manganese sulphate and boric acid.Spraying method (time and amount): the seedling flower bud phase sprays foliage fertilizer 1 time, sprays urea 70-100g/ mu, potassium dihydrogen phosphate 100-150g/ mu; 1-2 foliage fertilizer of flowering and boll-setting period foliage-spray, sprays the about 200g/ mu of urea, potassium dihydrogen phosphate 250g/ mu, boric acid 100g/ mu, and spray 1-2 the time of infertility, and combinationization is transferred in row foliar applied fertilizer conventionally;

Chemical regulation:

The cotton intercropping of the jujube cotton field time of infertilityization is adjusted 2-3 time, regulate and control number of times few 1-2 time compared with nonoculture cotton field, 8 grams/acre of mepiquat chloride consumptions, regulation and control intensity is lower than nonoculture cotton field, and wherein the seedling flower bud phase sprays mepiquat chloride 1g/ mu, flowering and boll-setting period is as more prosperous in growing way, every mu sprays mepiquat chloride 3g/ mu, after pinching 1 week, sprays mepiquat chloride 4g/ mu, prevents the prosperous length of side shoot, adjust part instead of chemical regulation measure by drip irrigation time and drip irrigation amount in addition, reach and build better cotton yield group structure;

Disease pest and weed control:

Jujube tree intercropping cotton pest mainly contains cotton spider mites, cotton bollworm and cotten aphid, and wherein heavier with cotton spider mites harm, cotton spider mites control is the emphasis of the cotton stripping field of jujube " three worms " control, and jujube tree intercropping cotton field disease mainly contains fusarium wilt, verticillium wilt and damping off;

Jujube tree intercropping cotton pest mainly contains cotton spider mites, cotton bollworm and cotten aphid, in jujube tree intercropping cotton field anti-curing the disease, prevent that these insects from should follow the control principle of " early investigation, early find, early control, non-chemically control maximize, chemical control minimizes and do not pollute jujube and the cotton joint defence of jujube " when worm, grass, cotton-plant pest-insects are noted and jujube pest joint prevention and control when control;

Cotton spider mites control: while there is cotton spider mites harm, carry out in time chemical control, conventionally spray Baume 5 and spend lime sulfur or 50-80 times of Suo Libaer before jujube tree rudiment; Within after jujube tree blooms 8-l0 days, spray 20% clofentezine or 20% pyridaben 2000-3000 doubly, for preventing that cotton spider mites from developing immunity to drugs to single agricultural chemicals, can rotation use the i.e. special acaricide agent such as dead, propargite, Avermectin, macro tetrolide of hexythiazox, pyridaben, mite, in the time of spray medicine, take the method for " enclose to justify to get ready, enclose and a little beat sheet ", careful large area medication;

In addition can take following measures to reduce cotton spider mites harm: take as far as possible autumn ploughing winter irrigation mode, remove cotton field and surrounding weeds, control two spotted spider mite grows, and pulls out in time the weeds such as field denticulate ixeris herb, field bindweed, reduces cotton spider mites host; When jujube tree and cotton occur that damage caused by a drought or spot film are suffered from drought, cotton spider mites harm is heavier, once two spotted spider mite harm is found to occur in cotton field, should irrigate in time, and strengthen filling amount and irrigation frequency, increase field humidity, construction is unfavorable for cotton spider mites growth and development environment, and can reduce harm; When the spring grafting in the 2nd year of the cotton intercropping field in cleaning rural area, particularly jujube, the branch of cutting and weeds in field should clean out ground in time;

Cotton bollworm control---non-chemically control: irrigation before seeding, take as far as possible autumn ploughing winter irrigation mode, be conducive to reduce cotton bollworm, the hibernating base of the pupas such as cutworm, to can not winter irrigation cotton field, in conjunction with spring irrigation, carry out cutting the ridge in water, reach the object except pupa, in cotton management process, final singling in good time, intertill and clean tillage, reject worm strain, can eliminate ovum and the larva of part insect, adopt cotton and corn, wheat, rape, the plot such as Chinese sorghum are adjacent to be done, or in cotton field surrounding, field planting corn, clover, Chinese sorghum, the bait crops such as spring rape. not only for natural enemy provides the suitable place of perching and breed, thereby increase Natural Enemies and quantity, also can lure collection cotton bollworm, be convenient to catch and kill, if the corn of cotton field surrounding plantation is Chrysopa, the natural enemy such as ladybug and parasitic wasp is created good living environment. control cotton bollworm effect remarkable,

In cotton field, place gyplure, clap net, black light lamp or high-pressure sodium lamp trapping cotton bollworm adult, in cotton bollworm first generation emergence Sheng phase (mid-June-early July), branch of poplar is bundled into pencil, and insert in the middle of cotton field, insert 3-4/mu, and before sunrise every day of cotton bollworm emergence Sheng phase, entangle with mesh bag after poplar branch handle, rock, reach the object that catches cotton bollworm adult;

Cotton field surrounding and field planting corn belt, 200-300 plant/acre, lures collection cotton bollworm to lay eggs, and manually smears ovum, Kill the larva or concentrates and prevent and treat with the BT preparation that does not contain banned substance, or surgerying at the beginning of 7 months, takes out of outside field;

While there is cotton bollworm harm in the cotton intercropping of jujube cotton field, artificial capture method as early as possible;

Cotton bollworm---chemical control: when cotton bollworm reaches index for control, should select biopesticide and the chemical pesticide little to natural enemy lethal effect, biopesticide has Bt preparation, cotton bollworm NPV preparation, Avermectin, pleocidin, the seal plain preparation etc. of remonstrating with, chemical pesticide has the red missible oil of match, cream of decamethrin, gamma cyhalothrin and other pyrethroid pesticide etc., biopesticide is because having stronger selectivity, harmless to people and animals, crops and natural enemy, free from environmental pollution, but higher to insect toxicity, be difficult for producing the insecticide of resistance, thereby be widely used;

" curing mainly the second generation; choose and control a three generations " answered in chemical control, while respectively reaching index for control for worm amount, in larva (first generation mid-May-early June in the low length of time, second generation late June-early July, third generation early August-mid-August) with 2.5% gamma cyhalothrin 30ml/ mu or 2.5% cream of decamethrin 30ml/ mu or 35%100ml/ mu, be dissolved in 30kg/ mu water and spray, chemical control must have been concentrated in 1-3d;

Cotton field cotten aphid control: do a good job of it investigation and the control of center, cotton field cotton plant, with stem brush, drip the heart, yellow plate and lure aphid, discharge the natural enemies such as ladybug or manually eliminate the methods such as cotten aphid and carry out, cotton field surrounding and middle place yellow plate trapping cotten aphid, remove cotton field surrounding weeds, the growing and spread of prevention and control of aphides;

Cotton field periphery cotten aphid (aphid source) control: for the aphid source of surviving the winter on home flower and greenhouse vegetable that prevents moves to the cotton intercropping of existing jujube cotton field, also should focus on the aphid source control of surviving the winter on home flower and greenhouse vegetable, concrete measure is: indoor flower buriing 15% iron of 20cm bore flowerpot go out gram 0.5-1.0 gram or 3% Furadan 5-10 gram, and greenhouse vegetable is sprayed with 2.5% decis 1:1500 times of liquid; Before laying eggs on the outdoor overwintering hosts such as mid or late April and early and middle ten days control in October pomegranate or produce the cotten aphid before alatae after hatching, spray with 40% flolimat or 40% chlorpyrifos ec 1000-1500 times liquid;

In time also can use of insecticide when spot film occurs, as controlled with agricultural chemicals rotation spot film sprays such as Imidacloprid, pyridine worm miaow, Diacloden water dispersible granules, chlorpyrifos ecs, stop and spread.But in the time of spraying pesticide, must guard against and be sprayed onto on jujube tree;

Blight control: main by plantation disease-resistant variety, stop to use morbidity cotton field to expand the seed of numerous production, also can be by basking seeds, the physical method such as warm water processing, grain-by-grain seed selection processes seed, with kill pathogens or reject seed in spite of illness, particularly effectively suppresses the generation of the sick and seedling pinta of carbon resistance in seedling stage;

Strict a small amount of drip irrigation irrigation method repeatedly, is conducive to reduce cotton field humidity, because high humility is that disease creates favorable conditions;

Other extermination of disease and insect pest (seedling blight and cotton thrips): suggestion adopts fungicide-treated seed, chemicals treatment cotton seeds is divided into seed coat agent or dressing seed conventionally, treatment agent is main component mainly with carbendazim, the vertical withered spirit of methyl, fenaminosulf, Imidacloprid aqua etc., prevents and treats damping off and cotton thrips harm thereby reach;

Control of weeds: broadcast front chemical weed control: in conjunction with the whole ground weeding on jujube tree ground, the trefanocide 80-100ml of every mu of use 48% is watered 30kg, and limit spray side drag (harrowing dark 8-10cm), makes medicament evenly mix with soil, to improve herbicidal effect, when spray medicine, should prevent that agricultural chemicals is sprayed onto on jujube tree;

Pour water will be in conjunction with the weeding of jujube tree ground after topdressing time, remove in time weed in cotton field, be beneficial to field ventilation and penetrating light, guarantee that cotton liquid manure is in liberal supply;

In Cotton Production process, by elite seed, rational close planting, plastic mulching, under-film drip irrigation, machinery and artificial weeding and change crops with other shift of crops scientifically and rationally, form the ecotope that is unfavorable for weed growth, can obviously alleviate weeds harm;

Pinch:

Pinch: Topping Time completed and pinches in 5-10 day in July in good time;
