Description
Affiliated technical field
The present invention relates to a kind of cotton cultivation method, belong to agriculture field.
Background technology
Cotton is the more loaded down with trivial details crop of a kind of cultivation management recruitment, from sow, grow seedlings, be transplanted to fertilising, prune, go and buy Chinese medicine, pick up the flower etc. the road procedure all need manual operations, particularly the alms bowl processed in the nutrition bowl seedling transplanting process, fortune alms bowl and transplanting labour intensity are large, this all goes down town for the between twenty and fifty labour in present rural area and works, staying is in, and that grow cotton is all old man and these weak labourers of child, really is difficult to be competent at.To throw work many due to cotton, and mechanized operation level is low, and labour intensity is large, and comparative effectiveness is low, so this several years Cotton in China cultivated areas fall sharply, and the external interdependency of cotton continues to increase, and has brought very large hidden danger for the sound development of China's textile industry.So carrying out the light letter cultivation of cotton is the inexorable trend of Cotton Production development, is the important measures of stablizing Cotton Production.
Summary of the invention
The application's method is made paper web or paper pot or paper cave dish by mechanization, Mechanized Processing straw substrate seedling, replace the soil property nutritive cube, and can carry out mechanization transplanting, guarantee that survival rate is more than 98%, without any seedling-slowing stage, can also omit when transplanting and water and laying plastic, the abridged edition environmental protection does not also have public branch can remove the training operation from after cotton is planted, output improves more than 20～30% than nutritive cube.
The technical scheme that realizes above-mentioned purpose and take comprises
One, the preparation of matrix:
1). the crop stalk through pulverizing or sawdust or rice hulls are packed in fermentation tank, add water by 50～200% of fermentation materials weight in fermentation tank, then 0.1～10% microbial inoculum and the nutriment that add weight of material, in fermentation tank, temperature is controlled at 50～65 ℃ always, impel microorganism to breed under optimum condition, adopt the even input and output material mode of layering, in time export the bottom material of slaking, like this at the bottom of tank every day uniform discharge one deck, top uniform feeding every day one deck, the layering fermentation, every day, new material was fermented rapidly.Also available Boiler Steam passes into the method that disinfection in straw heap or stack retting become thoroughly decomposed and processes matrix.
2. expect ripe post-drying or dry, add bio-fertilizer or chemical fertilizer by 0.1%～10% of matrix material weight, 0.0001%～5% adds bactericide by weight, gets half material bagging standby, and this material is designated hereinafter simply as straw matrix;
3). get the material of reserving half and make seedling medium by the volume ratio preparation coal ash of 1: 0.25～1: 10 or stove quarrel or vermiculite or perlite or the peat composed of rotten mosses or sawdust or bentonite or earth or sandstone or fowl and animal excrement fertilizer, press 0.01%～10% of dry material weight after mixing and add water-loss reducer, this blending the material of other matrix be designated hereinafter simply as composite matrix.
Two, grow seedlings:
1). with internal diameter 1～15cm, the seedling growth paper tube of high 1～30cm or paper pot or paper cave dish or paper bag lie on bobbing machine, add straw matrix in the bobbing machine hopper, machine toward paper web or paper pot or the interior filling of paper disc matrix, stop feeding in raw material during apart from upper opening of container 1cm left and right, after jolt ramming, take off paper web or paper pot or paper disc or paper bag, move on sower.
2). sowing: the cotton seed with selected sterilization is sowed with sower, and seed of every bunch planting is after planting planted with composite matrix lid, waters, and insulation is grown seedlings.There is no place that condition uses machine manually filling substrate and artificial seeding yet.
3). seedling management: before emerging, day temperature is controlled at 25～30 ℃, and nocturnal temperature is controlled at 15～20 ℃, and fine day morning every day or dusk are replenished illumination 2～4 hours with light, and is overcast and rainy with the additional illumination of light 12～14 hours.Find between nursery stage should in time sprinkle water when cotton seedling leaf has the slight wilting signs of drought.
4). transplanted front 1～3 day: spray 25% pyrrole ketone wetting powder 20～30g/666.67m
2Or 10% imidaclothiz wetting powder 20～30g or 1500 times of liquid of 10% Nitenpyram wetting powder, the suckings pest such as the cotton plant bug of control.Spray the harm of spiral shell mite ester control two spotted spider mite, using dosage is by 5000～6000 times of dilutions of registration dose dilution.
Spray 500～1000 times of liquid of high activity potassium fulvate during transplanting, to close cotton seedling part holes, reduce cotton seedling moisture transpiration, hestening rooting.Or with methyl α-naphthyl acetate 0.1%～10%, indolebutyric acid 1%～50%, sucrose 1%～40% is made into root-growing agent, is watered 100～1000 times and spills and impose on hestening rooting around cotton seedling shoot root border.
Three, site preparation and fertilization:
Plough and rake the soil level with the rotary tillage machine, and the while basal dressing, spray herbicide, ridge, ditch and edge of a field rand, the discrepancy in elevation is no more than 3cm, and the ground grading is thin.
Four, transplant:
1). select the transplanter that is fit to local soil condition to transplant, transplant, water, earthing carries out simultaneously.
2). can manually not transplant in the situation that have condition to adopt machine to transplant yet.
Five, field management:
Machine buriing slow-release fertilizer, machine sprays Rynaxypyr, spiral shell mite ester, pyrrole ketone, imidaclothiz, boron fertilizer, Nitenpyram, amino acid, compound sodium nitrophenolate.Machine is received flower.
Compared with prior art the application has following advantage.
(1). owing to having adopted fermentation tank to carry out straw fermenting matrix, fermentation tank is as required, and is changeable, and the vertical mixing tank of the similar cement of profile precast plant is welded with 10～15mm steel plate, and external Boiler Steam heating keeps in tank fermentation temperature required.The another airduct of connecting is connected with external fan blower, and the oxygen supply of being convenient to blow is satisfied substrate fermentation to the needs of oxygen.Can overcome like this contradiction that traditional stack retting straw is difficult for becoming thoroughly decomposed, greatly shorten fermentation period, improve fermentation efficiency.
(2). light simplification, due to paper web or paper pot or paper point disk seedling growing with the preparation soil in traditional feeding block seedlings raising process, regulate acidity, add fertilizer, alms bowl processed, get the heavy operating process such as alms bowl, fortune alms bowl, transplanting, be reduced to papery nutrition barrel or paper pot or paper cave dish by the industrialization means, each paper web or paper pot or paper disc are filled the weight of matrix and are also only had 1/5～1/3 of soil property nutritive cube; Specifically, before nutritive cube alms bowl processed, every mu of cotton need prepare alms bowl soil 1000～1200kg, alms bowl 500～600kg processed, transplant the land for growing field crops and need transport alms bowl 300～350kg left and right, visible task heavy, and adopt the paper web every mu of cotton seedling of growing seedlings only need prepare the matrix 60kg such as straw or coal ash left and right, transport to the land for growing field crops after water and transplant gross mass and also can not surpass 100kg even if spill before transplanting to execute to send to transfer, want light several times than the soil property nutritive cube, simplified numerous and diverse traditional seedling raising process, alleviated labour intensity.
(3). saving of labor's synergy, make the standby soil of 1 mu of Cotton Fields nutritive cube and need 1 of recruitment, alms bowl processed needs 1 of recruitment, and 2 of recruitments are transplanted in 1 of sowing recruitment, these work must be completed in manual operation, by the labor cost of 60 yuan/day, 300 yuan of meter wages, and adopt paper web to grow seedlings can the machine sowing, machine transplants, growing seedlings and transplant cost in every mu of stand is only 30 yuan of left and right, saves more than 200 yuan; The operating efficiency that machine is transplanted surpasses artificial 5～10 times of transplanting, and possess fertilising, the several functions such as water, transplanting land for growing field crops survival rate is more than 98%, normal operating can reach 100%.Save time, the saving of labor, save worry, the peasant no longer grows seedlings, and saves growing seedlings man-hour of a wheat harvesting period, can go out in short-term to do manual work and make money.Seedling growth paper tube or paper pot or paper disc rot after planting soil gradually voluntarily, and be very easy to use to soil, environmental nonpollution, can avoid the inconvenience that causes because of nutrition bowl seedling transplanting.Transplant simultaneously light simply, output is high, increases income significantly, and cotton shoot root system is flourishing, and Resistant and bad climate ability significantly improve.
(4). increase production and improve productivity, owing to being that the band container is transplanted, seedling does not hinder root under the protection of paper web or paper pot or paper cave dish, can be transplanted to safely the land for growing field crops, and survival rate is higher.Plant to set up good rhizosphere relation with soil very soon after soil, significantly improved transplanting survival rate, and tiller is fast, there is no seedling-slowing stage, early growth to cotton has significant facilitation, picking time ahead of time, the flower rate is high before frost, transplant volume increase more than 20%～30% than nutritive cube, more than 500 yuan of mu volume increase value.
(5). cost-saving synergistic, because nutritive cube can occur damaged in the transplanting process, so usually will prepare some pot seedlings in alms bowl processed and sowing more, namely plant one mu of cotton and will make the earthen bowl of two mu nearly, use cotton seed 350g, adopt paper web to grow seedlings does not need to do the preparation alms bowl more, only needs the 150g seed, thereby saves seed more than 40%.
(6). carry out raising seedling of cotton owing to adopting crop stalk to add the work seedling medium, the straw matrix structure is good, and unit weight is little, permeability is good, water conservation, nutrient preserving capability are better, is specially adapted to do matrix, straw matrix with after, can make fertilizer and be used for also field, make nutritive element obtain the Natural Circulation utilization, and can increase the organic matter of soil, culture fertility, reduce unit weight, increase soil porosity, chesson plays the effect of good improvement soil.
(7). carry out raising seedling of cotton owing to adopting crop stalk to add the work seedling medium, both saved cost, having opened up again one turns waste into wealth, recycling agricultural economy new road.Economic environmental protection realizes brand-new circular agriculture, the ecological agriculture.
(8). owing to having adopted water-loss reducer to carry out the method for raising seedling of cotton, can prevent that cotton seedling from planting behind the land for growing field crops witheredly because of arid, improve survival rate, guarantee cotton seedling normal growth growth.
(9). owing to having adopted the microbial inoculum microorganism to carry out the method for raising seedling of cotton, utilize and breed mycelia absorption nutritive element and moisture rapidly, the place that this mycelia tensible is far away apart from root has enlarged absorption area.The microbial inoculum microorganism can also secrete organic acid in addition, impels some not diffluent inorganic and organic matters to change into solvable nutrient, absorbs for cotton seedling.Moreover beneficial microbe is growth hormone and the amino acid isoreactivity materials such as the continuous release basic element of cell division, heteroauxin, gibberellin in the breeding metabolic process, powerful hestening rooting, make that root is white, root is long, capillary radical amount doubles above, inhale fertile water absorbing capacity and greatly strengthen, stem is thick, and seedling is strong.After mycorhiza death is cleared up, the mineral materialization of mycelium own, and be present in soil with free nitrogen-containing compound, can absorb for cotton plant, can make the growth rate of cotton plant amount increase more than 30%.
(10). owing to having adopted sucrose to carry out the method for raising seedling of cotton, because of indolebutyric acid and methyl α-naphthyl acetate all water insoluble, and burn the in addition shortcoming of plant leaf blade of indolebutyric acid, indolebutyric acid and methyl α-naphthyl acetate are fused in sucrose solution concentrate, make carrier with sucrose, make pulvis, do not produce and burn the leaf phenomenon.Sugar has the effect of hestening rooting in addition, and cell sap concentration is increased, and the flow of water descends, thereby can play the effect of solid water, water conservation, anti-wilting.
(11). owing to having adopted fulvic acid or Xanthohumate, not only can promote root system development, improve improving activity of root system, and can also make more moisture and the nutrient of cotton shoot root system's absorption, reduce the stomatal opening intensity of cotton seedling leaf, reduce the blade face transpiration, thereby reduced the cotton plant water consumption, strengthening the drought resistance of cotton seedling, is a kind of good anti-rising leaf-protecting agent.
(12). owing to utilizing rational illumination and temperature between nursery stage, impel cotton seedling to carry out flower bud differentiation, cotton does not break up public branch, directly grow fruit branch after being transplanted to the land for growing field crops, saved the operation that former nutritive cube cotton must carry out artificial pruning (go public branch), save artificial 2, simplified hypervisor for every mu.In addition, because cotton directly grows fruit branch, fruit branch that the tight knot position is lower, and Cotton growth is sane, is difficult for lodging, is conducive to realize stable high yield.
(13). for a long time, on agricultural, borax is used as boron fertilizer, borax has the characteristics such as poorly water-soluble, when using as foliage fertilizer, can only be in the hot water more than 40 ℃ solubilized.When the aqueous temperature of dissolving dropped to below 40 ℃, borax is crystallization in water again, and this can make shower nozzle stop up, borax solution is sprayed onto on crop, and moisture also can evaporate very soon, and borax can form the very thin crystallizing layer of one deck on the blade face, can not enter into and do in object, effect is very undesirable.And adopt polymerization boron, and under normal temperature (20 ℃), its solvability is 3.6 times of common borax, good water solubility, and not limited by water temperature, and can be mixed with chemical pesticide with any foliage fertilizer, can be absorbed fast by crop leaf after spraying.
(14). the mechanized harvest cotton, as far back as the thirties in 20th century U.S.'s machine cotton picking just be applied to produce, Xinjiang of China was introduced existing more than 20 year so far from 1989, but all be difficult to use always, reason is that the machine moits of gathering are high, be mainly mulch film to the pollution of unginned cotton, cause the grade of commodity cotton to descend.And the application's method cotton does not need covering with plastic film can survive when transplanting in the same old way yet; because this method is furnished with water-loss reducer in matrix; can protect the required moisture of growth rate of cotton plant in considerable time; so not with preserving soil moisture by spreading; thereby reduced pollution; reduce cost, and be more suitable for machine receipts flower.
(15). using of Controlled Release Fertilizer, from simplifying fertilising, Controlled Release Fertilizer is the new technology direction of agricultural production and streamlining management.The Synergy of release and release control fertilizer set urease inhibitor, digestion inhibitor and phosphorus element activator, improve the utilization ratio of nitrogen phosphorus fertilizer, nitrogenous fertilizer is valid up to 120 days by inhibitor, the nutrient of Wrapped fertilizer is along with process and discharge quickening breeding time, the operation of repeatedly applying fertilizer can be reduced to 1～2 time like this, single-dose application is the high-tech target of fertilising.Experiment and demonstration result, cotton field are used Controlled Release Fertilizer can save 1/3 fertilizer, and fertilizer application frequency reduces 3/5, and the saving of labor obtains the good result of volume increase 10% more than 60%.
(16). using water wisely, do not need pouring to transplant water, can save about irrigation water 200 sides for every mu.
(17). do not transplanted the impact of ground herbicide spraying, before the cotton replanting land for growing field crops, generally can spray steriland herbicide in the land for growing field crops, the root system of nutrition pot cotton seedling has grown the alms bowl body in a large number when transplanting, these root systems that grow outside earthen bowl are subject to the weed killer herbicide murder by poisoning of pedo relict and stop growing even dead, so it is longer to cause the nutrition pot cotton seedling to plant into the land for growing field crops seedling-slowing stage, and the cotton shoot root in this method is the leg protection that all is subject to paper web or paper pot, do not touched the soil of residual weed killer herbicide, so avoid the impact of weed killer herbicide, do not produce slow seedling phenomenon, cotton is early planted and can early send out.
18). this method is not only used on raising seedling of cotton, can also be in agricultural vegetable gardening flowers and the field extensive use of traditional Chinese medicine seedling raising and transplanting.
