Abstract
The invention relates to a fertilizing method for corn, comprising the steps of selecting biogas slurry and biogas residue normally producing biogas for two months or more; soaking seed with the biogas slurry, wherein soaking is carried out for 10 hours; applying base fertilizers, wherein the biogas residue, calcium superphosphate, potassium chloride and ammonium chloride are applied as the base fertilizers, and sodium of polyaspartic acid is mixed into the base fertilizers, the fertilizers are directly spread to the field and the soil is ploughed immediately with the depth of 6-9cm; and applying additional fertilizer, wherein three fertilizing periods are needed, namely, jointing fertilizer, spike fertilizer and particle fertilizer; the period of jointing fertilizer is to spray mixed solution of the biogas slurry and sodium of polyaspartic acid to the leave surface in the first three days of jointing; the period of spike fertilizer is to additionally apply ammonium chloride ten days before spike outgrowth in the large bell mouth period of corn; and the period of particle fertilizer is to spray the biogas slurry on the leave surfaces one day before and after corn pollination.
Description
Technical field
The present invention relates to a kind of cultivating method of crop, particularly relate to a kind of fertilizing method of corn.
Background technology
Corn is important cereal crops, and in China, its cultivated area is only second to paddy rice, wheat, occupies the 3rd, but Maize Production compares with other cereal productions, and input cost is higher, and output benefit is on the low side.The Maize Production fertilizer requirement is large, and input cost is high, causes the Maize Production high yield not efficient, and Higher output is not accompanied by a higher income; In recent years simultaneously, the biogas construction development had produced good economic benefit and social benefit fast, but the timely digestibility and utilization of biogas discarded object, also can affect the biogas generating pit normal operation and circulated.Not only nutrient is complete, fertilizer efficiency is fast for liquid natural pond, natural pond slag, and easily absorbs, and is residual few, is convenient to improve the rhizospheric environment of soil, and chesson seldom has salt accumulation, has the slow fertilizer efficiency characteristics that have both of speed and the effect of disease-resistant insect; Poly-aspartic-acid is a kind of amino acid whose polymer, and a kind of water-soluble polypeptide is biodegradable, has certain biologically active, its as fertilizer sources synergist, can absorb with enrichment soil in the element favourable to plant growth, can improve the availability of fertilizer. strengthen crops resistance.
Summary of the invention
Technical problem to be solved by this invention provides a kind of cheaply cultivating method of crop of high yield, this method combines physiological habit that the output of corn forms and the functional characteristic of biogas residue and biogas liquid and poly-aspartic-acid, takes full advantage of slow fertilizer efficiency and the characteristic of disease-resistant insect and the output that the poly-aspartic-acid fertilizer synergistic improves corn that has both of biogas residue and biogas liquid speed.
In order to overcome the above problems the fertilizing method that the invention provides a kind of corn, may further comprise the steps:
The first step: selected normal gas producing 2 months and above natural pond liquid and natural pond slag;
Second step: natural pond liquid seed soaking: select fine day to bask seeds, ted 1～2 day, removal of impurities, then will shine good seed packs in the woven bag, and reserve in the bag 1/4th space, and hitching sack with an end of rope, the other end is fixed on the discharging opening limit of biogas generating pit, make seed be in the middle part of natural pond liquid, soaked 10 hours, seed soaking should clean up seed after finishing with clear water, then dry, in order to vernalization, sowing;
The 3rd step: base manure: the natural pond slag of every mu of 700kg, 40kg superphosphate, 25kg potassium chloride and 25kg ammonium chloride are made base manure, sneak into simultaneously the poly-aspartic-acid of 40% concentration of 3kg, directly spill the field face and plough immediately the degree of depth 6～9cm;
The 4th step: topdress: be divided into three fertilizing times, jointing fertilizer, ear manuer, granulated fertilizer; Jointing fertilizer be jointing in the time of front 3 days foliage-spray with the natural pond liquid 20～30kg of about 1 times of clear water dilution and the mixed liquor of 45% concentration poly-aspartic-acid, 0.8～1kg; Ear manuer is in the corn typhon mouth phase, apart from going out fringe 10 days, is affixed by 40kg/ mu ammonium chloride; Granulated fertilizer is in the corn pollination 1 day time of front and back, and foliage-spray is with natural pond liquid 10～15kg/ mu of about 1 times of clear water dilution.
Useful effect: use the liquid seed soaking of the inventive method natural pond not only can improve germination rate, the percentage establishment of seedling of seed, promote the seed physiology metabolism, improve seedling quality, and can strengthen that rice shoot is cold-resistant, disease-resistant, anti-adversity, biogas residue and biogas liquid takes full advantage of the slow fertilizer efficiency that has both of biogas residue and biogas liquid speed, so make base manure and topdress, simultaneously biogas residue and biogas liquid can also disease and insect resistance, and poly-aspartic-acid has fertilizer synergistic, has improved utilization rate of fertilizer, comprehensive utilization has improved the output of corn in maize culture.Meanwhile biogas residue and biogas liquid is turned waste into wealth, take full advantage of, beautified environment.
