Embodiment 1
[0019] A special organic-inorganic compound fertilizer for rape, which is prepared from the following raw materials in parts by weight (kg):
[0021] The preparation method of described amino acid chelating liquid is: putting 15 parts by weight of animal feathers into 20% sulfuric acid and hydrolyzing it for 8 hours to generate amino acids, then adding lime for neutralization, then adding 1 part by weight of chitosan, mixing After homogenization, the amino acid chelating solution is obtained;
[0022] The dried Pu-erh tea dregs are obtained by drying and sterilizing Pu...
Embodiment 2
[0032] On the basis of embodiment 1 granulation compound fertilizer, continue to carry out following steps:
[0033] (1) Put diatomaceous earth into 3-4 times the amount of water, then add 2-3% sodium lauryl sulfate equivalent to the weight of diatomite, 1-2% flat plus O, 4-5% wintergreen Oil, 3-5% aluminum hydroxide, stirred at a high speed of 5200-6500 rpm to obtain a dispersion slurry;
[0034] (2) Spray the dispersion slurry on the outside of the compound fertilizer particles and dry;
[0035] (3) Spray the pyrethroid mixture on the outside of the granule, and then dry it, or you don’t need to spray it.
[0036] The use of the above-mentioned fertilizers increases the slow-release characteristics, and the amount of fertilizers can be reduced by about 20% per mu, while the yield remains basically unchanged.

Abstract
The invention discloses a special organic / inorganic composite fertilizer for rape. The special organic / inorganic composite fertilizer is prepared from the following raw materials in parts by weight: 5-8 parts of shrimp chaff, 10-15 parts of ascophyllum nodosum, 25-30 parts of sheep manure, 5-8 parts of dry Pu'er tea dregs, 3-8 parts of bone meal, 1-2 pats of EM microbial inoculum, 20-25 parts of rotten hami melon, 15-20 parts of rotten orange, 5-9 parts of rotten Chinese gooseberry, 20-25 parts of peat soil, 8-10 parts of bean pulp, 10-15 parts of wheat flour, 3-5 parts of amino acid chelated solution, 8-12 parts of straws, 35-40 parts of urea, 15-18 parts of diammonium hydrogen phosphate, 28-30 parts of potassium chloride, 1-2 parts of zinc sulfate, 5-8 parts of common andrographis herb, 2-4 parts of thunder god vine, and 2-4 parts of camphor tree leaves. The special organic / inorganic composite fertilizer disclosed by the invention is a special formula fertilizer particularly prepared specific to rape growth, and has the advantages of effectively improving the disease and drought resistance of the rape and reducing damages to soil correspondingly, and in addition, by airtight fermentation application of rotten fruit pulp, the dry Pu'er tea dregs and the like, the advantages of saving cost and turning waste into wealth are achieved while the nutrient content of the fertilizer is enriched.
Description
technical field [0001] The invention relates to the field of fertilizers, in particular to a special organic-inorganic compound fertilizer for rapeseed. Background technique [0002] Fertilizer is a type of substance that provides one or more essential nutrients for plants, improves soil properties, and increases soil fertility. One of the material basis of agricultural production. As early as the Western Zhou Dynasty, China already knew that field weeds can promote the growth of millet after they rot. "Qi Min Yao Shu" introduces in detail the method of planting green manure and the method of crop rotation between leguminous crops and gramineous crops; it also mentions the method of using crop stalks mixed with cow dung and urine, trampling and composting to make fertilizer . [0003] my country is a large agricultural production country. With the high utilization of fertilizers, the requirements for fertilizers are constantly increasing. At present, a large amount of ino...
