Problems solved by technology

However, there are still disadvantages of varying degrees, most of which are due to the short fertilizer effect period, which cannot meet the nutrient requirements of crops throughout the growth period.
Although CN96119508.8 and CN98124282.0 invention patents belong to long-acting fertilizers, the fertilizer effect period is relatively long, which basically solves the problem of difficult topdressing of film-covered crops
However, the lack of improvement in the micro-ecological environment of the rhizosphere of crops and the insufficient distribution of beneficial microorganisms lead to the inability of the root system to fully absorb water and nutrients, resulting in the inability of the applied fertilizer to fully exert its maximum effect and the inability to obtain the maximum increase in production and income. At the same time, the quality of the product cannot be get better

[0009] Embodiment 1 cotton biological organic-inorganic long-acting compound fertilizer (percentage by weight)

[0010] First prepare the long-acting agent: weigh 1% of dicyandiamide, 1% of hydroquinone, and 2% of humic acid, mix thoroughly, add 3% of zeolite powder ≥ 200 mesh, mix well and prepare as material 1;

[0011] Then fully mix 7% of organic poultry manure, 15% of urea, 10% of superphosphate, and 3% of potassium and magnesium fertilizer for use as material 2;

[0012] Then fully mix 0.5% of EV preparation, 0.3% of zinc chloride, 0.1% of borax, 0.2% of manganese sulfate pentahydrate, and 0.01% of ammonium molybdate, and stir evenly for use as material 3;

[0013] Then surplus is that bentonite is material 4;

[0014] Fully mix material 1 and material 3, stir evenly, add material 2 and material 4, mix well, and use conventional double-roller extrusion granulation method to granulate, after forming, sieve through a sieving machine, test, Just pack it.

Embodiment 2

[0015] Embodiment 2 corn biological organic-inorganic long-acting compound fertilizer (percentage by weight)

[0016] First prepare EV, long-acting agent and trace elements: weigh 3% of EV preparation, 2% of dicyandiamide, 3% of hydroquinone, 5% of humic acid and mix thoroughly, then add 1% of zeolite powder of ≥200 mesh, heptahydrate 0.2% of zinc sulfate, 0.02% of boric acid, 0.2% of manganese chloride tetrahydrate, and 0.03% of sodium molybdate are fully mixed and prepared as material 1;

[0017] Then fully mix 10% of organic domestic garbage, 20% of ammonium phosphate, 12% of superphosphate, and 7% of potassium chloride for use as material 2;

[0018] Then surplus is that bentonite is material 3;

[0019] Mix material 1, material 2, and material 3 fully, and then use the conventional agglomeration method to granulate after stirring evenly. After adding a temperature-adjusting and humidity-regulating device to control the drying temperature, the drying equipment is used for...

Abstract

The invention relates to the development of a bio-organic-inorganic long-acting compound fertilizer. The compound fertilizer is composed of beneficial microbial flora-EV preparations, long-acting agents, organic matter, nitrogen fertilizer, phosphorus fertilizer, potash fertilizer and medium and trace elements zinc, boron, manganese, Composed of molybdenum, iron, sulfur, calcium, zeolite powder ≥ 200 mesh; after thorough mixing and stirring, it is made by conventional double-roll extrusion granulation method or agglomeration method. A large number of experiments have proved that the fertilizer effect period of this compound fertilizer is more than 160 days, which is more suitable for fertilization in autumn and then irrigation in winter, and its effect is better than fertilization in spring. The fertilizer utilization rate can be increased by more than 25%, the output of cotton and grain crops can be increased by more than 20%, and the output of sugar beets and vegetables can be increased by 40-50%. At the same time, the compound fertilizer can give full play to the maximum effect of fertilization, improve the micro-ecological environment of the rhizosphere of crops, make beneficial microorganisms occupy an absolute advantage, inhibit the generation and development of harmful microbial pathogens, and facilitate the absorption of nutrients by roots.

Description

technical field [0001] The invention relates to a bio-organic-inorganic long-acting compound fertilizer for crops Background technique [0002] In recent years, the development of compound fertilizers for crops has been rapid. Invention patents such as CN90105249, CN88101637, CN90105116, CN96119508.8 and CN98124282.0 all involve the research results of various types of compound (mixed) fertilizers, which have played a good role in agriculture and achieved certain results . However, there are still disadvantages in varying degrees, most of which are due to the short fertilizer effect period, which cannot meet the nutrient requirements of crops throughout the growth period. And though CN96119508.8 and CN98124282.0 patents of invention belong to long-acting fertilizers, the fertilizer effect period is correspondingly longer, which basically solves the problem that film-covered crops are difficult to topdress. However, the lack of improvement in the micr...
