Description

A kind of green manure and the cultural method of konjaku interplanting
Technical field
The present invention relates to proportion of crop planting technical field, more particularly to a kind of green manure and the cultural method of konjaku interplanting.
Background technology
Konjaku (Amorphophallus konjac) is Araeceae (Araceae) Amorphophallus The general name of (Amorphophophallus blume).Konjak cultivation have hygrophilous profit, be afraid of that ponding, happiness are nice and cool, be afraid of high temperature, like it is weak It is light, resistance to the characteristics of shelter from heat or light.Konjac tuber is rich in Glucomannan, pectin, alkaloid, starch and 17 kinds of amino acid and lot of trace member Element, is the unique a large amount of plants containing Glucomannan having now been found that, is widely used in food, medicine, weaving, cosmetics, stone The multiple fields such as oil.Due to the extensive use and all over the world understanding to konjaku, the market demand is increasing, outside konjaku powder The states such as Japan, the U.S., Canada are found a good sale in trade outlet.Due to the limitation of raw material, the annual production of China's konjaku powder is only 1.5 ten thousand Ton or so, it is difficult to meet the demand of domestic and international market.National konjaku deep processing enterprise has pulled planting industry to the demand of raw material Development, per kilogram fresh Amorphophallus rivieri 3.5-4.5 members, every kilogram of dry plate 25-30 member;Every kilogram of fine powder price 50-60 member.Plant konjaku mu The output value is in 5000-8000 members, and konjaku has turned into the Main Cultivation crop that local farmers are developed the economy.End the end of the year 2016, natural resources County's cultivated area reaches 120,000 mu, 177,500,000 kilograms of annual production, 4.7 hundred million yuan of the output value.Cultivated area accounts for the 1/10 of the whole nation, accounts for cloud The 1/3 of Nan Sheng, accounts for the 2/3 of Qujing.
Green manure (green manure) is used as the general name of the green plants body of fertilizer, and this paper green manure refers exclusively to cover in the autumn and winter Make the harvesting of Second Year spring and summer, belong to the sweet potato of legume.Its root rhizobium plays the role of nitrogen in fixed air, is both excellent Matter feed, is excellent green manure crop again.It is a kind of complete biological source of manure of nutrient, and abundant nutrient can be provided for soil, Convert difficultly soluble nutrient in soil, so that crop absorbs;The physical and chemical character of energy improved soil, promotes in soil The activity of microorganism.
The young young stem and leaf of green manure, containing abundant nutrient, once the decomposition in soil, can roll up organic in soil Matter and nitrogen, phosphorus, potassium, calcium, magnesium and various trace elements.Green manure fresh grass per ton can typically provide 6.3 kilograms of nitrogen, and phosphorus element 1.3 is public Jin, 5 kilograms of potassium, equivalent to 13.7 kilograms urea, 6 kilograms of calcium superphosphate and 10 kilograms of potassium sulfates.The root system hair of green manure crop Reach, if 1000 kilograms of aerial part fresh grass, underground root system just there are 150 kilograms, the soil organism can be rolled up, improve soil Earth structure, increases soil fertility.Leguminous greenmanuring crop can also increase the nitrogen in soil, according to measuring and calculating, and the nitrogen in leguminous green manure has 2/3rds be from air.Green manure is ploughed under after soil, in the presence of microorganism, is constantly decomposed, and is discharged a large amount of Outside available nutrient, humus is formed, humus is combined with calcium soil colloid is formed crumb structure, the soil for having crumb structure Loose, ventilative, retain water and nutrients ability is strong, regulation water, fertilizer, air and heat performance it is good, be conducive to second stubble crop to grow.For plant and Increase soil fertility and be combined, increase animal and fowl fodder supply, hill farmer always just has the custom of green manuring, and Fuyuan County is every year in wheel public land About 250,000 mu of green manuring, but also only account for the 35% of winter wheel public land.
Green manuring technology:Planting patterns has nonoculture, interplanting, miscegenation, a variety of plantation forms such as slotting kind, and implantation methods are optional Program request, drilling are broadcasted sowing.Main step has site preparation, seed selection, seed treatment, sowing, tillage and weeding, disease pest and weed to prevent and treat, cut Careless stock keeping, root stubble fertilize the soil, seed harvest.
Konjaku planting technology:Two-year system no-tillage ridge culture (net to plant) is cultivated, and the bio-diversity such as orchard interplanting, corn intercrop is planted Training.Main step has seed selection, site preparation, sowing, fertilising, field management, disease pest and weed integrated control, digging to receive.
The shortcoming that konjak cultivation is present
Requirement of the konjaku plantation to soil and blockclimate environment is higher, it is desirable to appropriate the moon covers, it is warm, moisten, avoid height Temperature, Qiang Guang, the climatic environment of frost and bulky are fertile, quality is loose, draining is ventilative good, organic matter is abundant and preceding stubble is not planted Planted the soil environment of the crops such as konjaku, vegetables, flue-cured tobacco, potato, radish.Only plant or the biology of (set) is more between other crops Sample is cultivated, and soft rot evil is all more serious, and this is that per unit area yield is low, the main cause that total yield supply is not asked.Generally use at this stage Two-year system no-tillage ridge culture cultivation technique, there is following shortcoming:
1st, it is the rational density of guarantee konjaku next year, plantation then must keep relatively low density, cause soil and illumination The waste of resource;
2nd, too low density and preferable soil fertility and illumination condition, cause weed growth vigorous, and next year weeding produces big The working hour expense of amount;
3rd, the konjaku planted then, which will arrive Second Year winter, could dig receipts, and planting household does not have economic benefit then;
4th, the winter konjaku plot of the falling after seedling free time is exposed, and ice and snow sleet weather causes serious damage to the ganoid konjaku taro in buried soil Wound, rapidly reduces emergence rate, and increase soft rot evil incidence causes the konjaku underproduction;
5th, to keep winter dormancy of the konjaku seed of two-year system no-tillage cultivation in soil, cause soil winter wheel not busy, Not only let a piece of farmland go to waste soil, also rapidly reduce feed resource;
7th, Amorphophallus happiness potassium crop, often applies the potassium ion displacement property in the high chemical fertilizer of potassium content, potash fertilizer in plantation It is especially strong, the polyvalent cation for forming soil granular structure can be cemented out, and the potassium ion of monovalence is acted on without key bridge, The key bridge of soil granular structure is destroyed, and also just destroys crumb structure, causes soil hardening, influences the konjaku of no-tillage cultivation Absorption to soil nutrient.
The shortcoming of nonoculture green manure (sweet potato) cultivation
1st, as net kind, the makeshift letted a piece of farmland go to waste simply is avoided, peasant planting is ready not high;It is used as culture fertility and part The supplement of feed, economic value is low, and land utilization ratio is not high;
2nd, fertilizer is robbed in various degree with other crop interplantings, interplanting presence to win honour for, and unfavorable field intertillage management, due to life The dislocation of phase is educated, there is crops for rotation contradiction.
In the konjaku planting process that developed recently gets up, soft rot evil is adjoint in whole konjaku crop cycle, causes to plant The heavy losses of son and yield.According to investigations, konjaku is planted only, and the loss of seeds caused annual about 1220 is infected due to what soft rot did harm to Ten thousand kilograms, about 70,000,000 kilograms of production loss.
The purpose of the present invention is the several shortcomings being directed in konjaku two-year system no-tillage ridge culture cultivation technique, a kind of energy-conservation of research and development Put forward effect, economically viable konjaku bio-diversity cultural method.
The content of the invention
The technical problem existed based on background technology, the present invention proposes the cultural method of a kind of green manure and konjaku interplanting.
Technical scheme is as follows:
A kind of green manure and the cultural method of konjaku interplanting, comprise the following steps:
A, konjaku plantation:
A-1 chooses seeds:The improved seeds of selected suitable local cultivation, its mode of appearance is that bulb is full, and terminal bud is scarlet sturdy, And seed taro disease-free, without wound;
A-2 site preparations:Pre- plantation plot is deep ploughed at the beginning of 3 months by the end of February, soil, thin upturned soil is shone, it is wide with 1.3-1.6m moisture in the soil face Ridging, the high 22-27cm in ridge, furrow width 28-32cm or so, in favor of draining, reduce konjaku disease;
A-3 is sowed:By 25cm × 30cm seeding row spacing water furrow planting, note handling with care when putting taro kind, never squeeze and press Bulb, eye is put upward, then shallow soil covering, thickness of earth covering 5-10cm;
A-4 applies fertilizer:Based on organic fertilizer, supplemented by high potassium compound fertilizer, heavy base fertilizer application is added and topdressed;
A-5 field management:Weeding carries out ridging of topdressing, never rainy day or morning simultaneously based on artificial pull out with reference to weeding Dew enters field when not dry;
A-6 integrated pest prevention and controls:The disease of konjaku mainly has soft rot, southern blight etc., can be with rich taro No. two in sowing When spread fertilizer over the fields with ditch or rhizosphere spreads fertilizer over the fields and prevented and treated during plant morbidity;7-8 month rainwater is more, is the peak period of konjaku morbidity, during which It is noted that dredging ditch water discharge, it is ensured that water route is unimpeded, while removing diseased plant and disinfecting;
A-7, which is dug, to be received:Mid-November next year, konjaku plant started down seedling, and seedling chooses fine day and starts to dig receipts, harvesting after 10 days Stem tuber sorted by size, with large bamboo or wicker basket or mesh bag packed and transported;
B Green manurings:
B-1 chooses seeds:From the Hairy vetch seed harvested then, it is desirable to which maturity is consistent, full seed, no soil block, Stone and broken grain seed;
B-2 seed treatments:Hairy vetch seed is soaked into more than 8 hours, Ran Houyang in sodium selenite solution before broadcasting Dried 1-3 days under light;
B-3 is sowed:The mid or late August (Limit of Heat climate and other natural phenomena of a season) for selecting rainfall abundant, at this moment konjaku is substantial in bulb dry Phase and rhizome (taro whip) growth period, weed growth are vigorous, and with reference to last time weeding, every mu with 2.5-3 kilograms of Hairy vetch Broadcast sowing or shallow ridges drilling, after planting with reference to artificial weeding, original place shake off weeds root system with soil and be attached to green on soil Fertile seed, is fully contacted and is evenly distributed with soil with sharp green manure seed, accelerates weeds dead, it is ensured that is emerged neat and is improved out Seedling rate;
B-4 field management:Winter-Spring weeds are excessive when winning honour for, and should make and pull out processing,
The B-5 prevention and control of plant diseases, pest control:When aphid damage is serious, uniformly sprayed with 1.5-2.0% Chongmankes 4000-6000 times of liquid of missible oil Mist is prevented and treated;
B-6 mowing stock keepings:The green manure grown, can gather in before the winter and once be used as greenfeed, cane should stay 10- when cutting green grass or young crops 15cm, is sprouted with sharp regrowth hair;
B-7 turns over infertile field:April next year, green manure is in full-bloom stage, is at this moment also biological yield maximum phase, konjaku is not yet Emerge (cone), green manure is cradled, used as fodder way then removes field and dries pulverization process;Make fertilizer purposes, then by green manure Grassy marshland uniformly lays moisture in the soil face, is suitably earthed up with reference to applying for phosphorus potash fertilizer, ridging covers tightly and is compacted green manure grassy marshland and is advisable, with profit Fully become thoroughly decomposed in green manure, quick-acting nutrients and good environment are provided for the growth of later stage konjaku.
It is preferred that, in described step A-1, described seed taro is the single breeding for focusing on 10-20g.
It is preferred that, in described step A-4, mu applies well-rotted farmyard manure 1800-2200kg, NPK 30-50kg work For base fertilizer;Topdress in two times, topdress for the first time in late June, Mu Shi composite fertilizers 15-22kg;Topdress for the second time in 5 months next years Ten days, Mu Shi composite fertilizers 18-25kg.
It is preferred that, in described step B-2, the concentration of sodium selenite is 500-800ppm.
It is preferred that, in described step B-7, after being cradled to green manure, 5-15ppm selenous acid is sprayed to green manure blade Sodium solution.
The implantation methods of traditional selenium-enriched konjac, are usually sprayed using selenium-rich solution seed soaking mode or directly to blade The mode of nanometer selenium, the product Se content that the former obtains is relatively low, and economic value is not high, and the latter's cost is too high, there is certain economy Risk;Using the interplanting addition selenium of green manure in the present invention, cardinal principle is:(Hairy vetch seed is to selenium concentration for green manure seed Tolerance it is very strong) after the substantial amounts of inorganic selenium of absorption,, can be enduringly by a part of nothing because selenium is excessive in growth course Organic Selenium after machine selenium and a small amount of conversion is discharged into soil by root, so that the root system of konjaku can be constantly from soil Absorb selenium element and be converted into Organic Selenium;When later stage green manure is in full-bloom stage, sodium selenite solution, supplement one are sprayed to green manure blade Quantitative selenium element, it is better.
Find that, by green manure and konjaku interplanting, the volatile materials secreted by green manure crop can also be killed by research The secretion of bacterium, its rhizosphere and microorganism has inhibitory action to soft rot opportunistic pathogen, plays important to reduction konjak soft rot evil Effect.Green manure and konjaku interplanting, do not fight for illumination and liquid manure resource mutually, take full advantage of soil space, increased income animal and fowl fodder; Soil texture and lifting land fertility can also be improved, fertilizer amount is reduced, Amorphophallus Yield and quality is improved.With green manure in konjaku Plot robs stubble and fills out not busy plantation, and easy to operate, extensive management, saving of work and time, peasant are easy to receive and promoted, and can be effectively increased plantation Family income.
The present invention is advantageous in that:
Economic benefit:Green manure and konjaku interplanting have been fostered and apply fertilizer soil fertility, are improved soil texture, are provided for konjaku growth Full price fertilizer and soil environment, can reduce the amount of application of next year chemical fertilizer, reduce the input cost of fertilizer.The two of interplanting green manure Konjak cultivation year processed, because green manure improves farmland blockclimate, soil environment, greatly reduces the konjaku incidence of disease, so as to carry High Amorphophallus Yield more than 30%.Flourishing green manure inhibits the growth and breeding of other weeds, reduces the group of next year weeds Body quantity, so as to reduce the working hour expense that next year konjaku is cut weeds.
Green manuring is easy to operate, extensive management, and every mu of green forage yield cultivates one at 1.5-1.8 tons equivalent to meeting The feed of 75 kilograms of big porker needs.The Vicia sativa nitrogen content of bud green feed is 0.47%, and folding protein is 2.9%, feeds one 75 kilograms of big porker, can be provided by taking around kilogram bud green Vicia sativa of 45 kilogram proteins, i.e., 1550 according to rough calculation by 45 kilograms Protein, that is, 0.07 hectare production green manure can meet cultivation one first 75 kilograms big porker feed needs, equivalent to section About 500 kilograms of corns (protein content of corn kernel is 8.0%), and in bud green forage grass, vitamin E, K and B races it Abundant, even more cereal fine fodder is incomparable.
Ecological benefits:Green manuring crop provides nutrient for second stubble crop, and forage grass source is provided for animal husbandry in agricultural area.It is carried The soil organism of confession, can effectively improve soil fertility, improve soil environment quality.Make between green manure crop and konjaku, to protection Konjaku seed safety is survived the winter, and reduction konjak soft rot evil, greatly raising Amorphophallus Yield play an important role.Green manure contains 15- 25% organic matter and 0.3-0.6% nitrogens, green manuring crop can increase the quantity of soil with organic matter and available nutrient.According to Nanjing Soil Inst., Chinese Academy of Sciences determines, and every mu applies 2500-3000 kilograms of the green manure such as Chinese milk vetch, sweet potato in farmland, Organic matter increase by 0.15% in topsoil, total nitrogen content increase by 0.01%.Green manure crop absorbs very capable, the pulse family of difficultly soluble nutrient Class green manure crop all has powerful root system, and main root buries relatively deeply, the general long 2-3m of root, can absorb and be difficult to make to be other in deep soil The nutrient that thing is absorbed.After after green manure decomposition, major part is stored in arable layer to these nutrients with effective form again again, the stubble for after Crop absorbs.
Green manure is ploughed under after soil, in the presence of microorganism, constantly decomposed, is discharged outside mass efficient nutrient, evil Humus is formed, humus is combined with calcium can make soil cementation into crumb structure, there is the loosing soil of crumb structure, ventilative, guarantor Water fertilizer-preserving ability is strong, regulation water, fertilizer, air and heat performance it is good, be conducive to plant growth.
Green manure and konjaku interplanting, take full advantage of soil space and illumination, and weeds are driven away using biological competition advantage.Green manure Root rhizosphere secreta is natural bactericide, can effectively be killed except to the unfavorable harmful pathogen of konjaku growth.Green manure stalk may be used also To be grown as organic fertilizer resource beneficial to konjaku, Amorphophallus Yield is improved.
The present invention makees in production practices using between green manure and konjaku, and the volatile materials secreted by green manure crop may be used also To kill bacterium, the secretion of its rhizosphere and microorganism has inhibitory action to soft rot opportunistic pathogen, and reduction konjak soft rot is done harm to To important function.Suppress weed growth using the biological competition advantage of green manure, make full use of soil space, improved soil fosters and apply fertilizer ground Power, improves the yield and quality of konjaku, is planting household increase economic benefit.
