Abstract
The invention relates to a fertilizing method of cotton. The fertilizing method of the cotton comprises the following steps of selecting a biogas slurry and biogas residues which normally produce methane for 4 months or more than 4 months; soaking seeds with the biogas slurry: soaking the seeds for 30 to 50 hours; adopting the biogas residues as a base fertilizer: adopting 1500kg of biogas residues, 15kg of calcium magnesium phosphate fertilizer, 10 to 15kg of potassium chloride, 1kg of zinc and 1kg of boron as the base fertilizer per mu; adopting diammonium phosphate as a seed manure: using 12kg of diammonium phosphate per mu, meanwhile, mixing 1.3kg of polyaspartic acid with concentration being 25 percent; adopting the biogas slurry as an additional fertilizer: dividing into three stages: (1) dressing in a flower bud stage: dressing 150 to 215kg of biogas residues and 10 to 15kg of ternary compound fertilizer per mu, and meanwhile, mixing 2kg of polyaspartic acid with concentration being 25 percent; (2) dressing in a flowerboll stage: dressing 10 to 15kg of urea and 350 to 400kg of biogas residues per mu; and (3) dressing in a last stage: spraying 25 to 35kg of biogas slurry which is diluted with clear water by about 1 time.
Description
Technical field
The present invention relates to a kind of cotton cultivation method, more particularly to one fertilizing method for growing cotton.
Background technology
Cotton Gossypii is important industrial crops, and it has a very wide distribution, and cultivated area is big, is the most important fibre crops of our times, while Cotton Gossypii is also the crop for needing fertilizer more；In recent years simultaneously, biogas construction development is quick, generates good economic benefit and social benefit, but biogas garbage can not digestibility and utilization in time, can also affect methane-generating pit normal work and circulation.Not only nutrient is complete for biogas slurry and biogas residue, fertilizer efficiency fast, and easily absorbs, and residual is few, is easy to the rhizospheric environment of improved soil, chesson seldom to have salt accumulation, the effect with the slow fertilizer efficiency feature having both of speed and disease-resistant insect.Poly-aspartic-acid is a kind of polymer of aminoacid, and a kind of water soluble polypeptide is biodegradable, with certain biological activity, it can absorb and element favourable to plant growing in Enriching soil as fertilizer synergist, can improve the utilization rate of fertilizer. strengthen crops resistance.
The content of the invention
The technical problem to be solved is to provide a kind of inexpensive cotton cultivation method of high yield, this method combines the physiological habit and biogas residue and biogas liquid of the yield composition of Cotton Gossypii and the functional characteristic of poly-aspartic-acid, makes full use of the fast characteristic and poly-aspartic-acid fertilizer synergistic for delaying the fertilizer efficiency and disease-resistant insect having both of biogas residue and biogas liquid to improve the yield of Cotton Gossypii.
In order to solve problem above the invention provides a fertilizing method for growing cotton, comprises the following steps：The first step：From normal gas producing 4 months and the biogas slurry and biogas residue of the above；Second step：Biogas slurry is soaked seed：Select fine day to be basked seeds, ted 2～3 days, remove impurity, then the seed for having shone is fitted in woven bag, and the space of a quarter in bag is reserved, and bag mouth is hitched with one end of rope, the other end is fixed on the discharging opening side of methane-generating pit, make middle part of the seed in biogas slurry, immersion 30～50 hours, after seed soaking terminates, should be clean by seed clean water, then dry, in case accelerating germination, sowing；3rd step：Biogas residue makees base manure：10～the 15kg of biogas residue and 15kg calcium magnesium phosphate and potassium chloride of every mu of 1500kg, each 1kg jin of zinc, boron makees base manure, mixes and spill field face and plough immediately；4th step：Diammonium phosphate (DAP) does seed manure：Seed manure is done with Diammonium phosphate (DAP), every mu of consumption is 12kg, while being mixed into 25% poly-aspartic-acid 1.3kg, imposes on 4～5 cun of depth below seed；5th step：Biogas slurry is topdressed：Cotton Gossypii is topdressed and is divided into three periods:One is flower bud fertilizer, Cotton Gossypii budding after 1～3 day when, 15～25cm zanjons are dug at 10～12cm of cotton plant per mu of 150～215kg biogas residue and nitrogen, phosphorus, potassium are applied respectively containing 15% 10～15kg of NPK, while be mixed into the poly-aspartic-acid of 25% concentration of 2kg, blinding immediately；Two is Hua Lingfei, and cotton plant is bloomed more than 80%, and when having tied 1～2 cotton boll on individual plant, 15～25cm zanjons are dug at 35～40cm of cotton plant per mu of 10～15kg carbamide and 350～400kg biogas residues is applied；Three is caping fertilizer, and two days before and after the beginning of autumn start, and to cotton field, per mu can spray the 25～35kg of biogas slurry for diluting 1 times or so with clear water, and 5～7 days once, even spray 2～3 times.
Beneficial effect：Germination percentage, the percentage establishment of seedling of seed not only can be improved using the seed soaking of the inventive method biogas slurry, promote seed physiology metabolism, seedling quality is improved, and rice shoot cold-resistant, disease-resistant, anti-adversity can be strengthened, biogas residue and biogas liquid makes full use of the slow fertilizer efficiency having both of biogas residue and biogas liquid speed, so making base manure and topdressing, simultaneously biogas residue and biogas liquid can also disease and insect resistance, poly-aspartic-acid has fertilizer synergistic, improves utilization rate of fertilizer, comprehensive utilization improves the yield of Cotton Gossypii in cotton culture.At the same time biogas residue and biogas liquid is turned waste into wealth, is made full use of, beautified environment.
Specific embodiment
With reference to embodiment, the invention will be further described.
Embodiment 1：One fertilizing method for growing cotton, comprises the following steps the first step：From the normal gas producing biogas slurry of 4 months and biogas residue；Second step：Biogas slurry is soaked seed：Select fine day to be basked seeds, ted 2 days, remove impurity, then the seed for having shone is fitted in woven bag, and the space of a quarter in bag is reserved, and bag mouth is hitched with one end of rope, the other end is fixed on the discharging opening side of methane-generating pit, make middle part of the seed in biogas slurry, immersion 40 hours, after seed soaking terminates, should be clean by seed clean water, then dry, in case accelerating germination, sowing；
3rd step：Biogas residue makees base manure：The biogas residue and 15kg calcium magnesium phosphate of every mu of 1500kg and potassium chloride 15kg, each 1kg jin of zinc, boron makees base manure, mixes and spill field face and plough immediately；
