Problems solved by technology

[0004] 1. The utilization rate of chemical fertilizers is low, which is likely to cause problems such as soil compaction and acidification, and pollute the environment;
[0005] 2. Organic fertilizers produced from animal manure are prone to antibiotics and heavy metal pollution, causing secondary pollution to the soil after use and affecting food safety;
[0006] 3. Soil fertility declines and the soil biological environment is destroyed, seriously affecting the sustainable use of cultivated land

Embodiment 1

[0029] An organic-inorganic compound fertilizer, comprising: 30-35 parts by weight of cassava residues, 10 parts by weight of urea, 20 parts by weight of ammonium chloride, 5.5 parts by weight of ammonium sulfate, 10 parts by weight of monoammonium phosphate, 10 parts by weight of The calcium superphosphate of 10 parts by weight, the potassium chloride of 10 parts by weight and the arbuscular mycorrhizal fungus agent of 0.12 parts by weight.

Embodiment 2

[0031] An organic-inorganic compound fertilizer, comprising: 32 to 37 parts by weight of organic fertilizer, 15 parts by weight of urea, 25 parts by weight of ammonium chloride, 5 parts by weight of ammonium sulfate, 20 parts by weight of monoammonium phosphate, 12 parts by weight of part of calcium superphosphate, 15 parts by weight of potassium chloride and 0.1 part by weight of arbuscular mycorrhizal fungal agent; the organic fertilizer is obtained after mixed fermentation of cassava residue and rice straw, and the ratio of cassava residue and rice straw is 5:1 The mass ratio is mixed.

Embodiment 3

[0033] Produce the organic-inorganic compound fertilizer in implementing 2, flow process is as figure 1 Shown:

[0034] Fermentation preparation of organic fertilizer: First, fresh cassava dregs are pressed by a solid-liquid separator or dried naturally to reduce their water content to 30% to 40%, and then the pure cassava dregs or cassava dregs and rice straw are mixed according to the weight ratio of 5:1 Mix and then ferment for 10 to 20 days. During the fermentation process, when the temperature of the fermentation material rises to 60°C, the compost is turned over, and the compost is turned 2 to 3 times during the fermentation period. After the fermentation is over, spread out the stacked material and dry it until the water content of the organic fertilizer is ≤20%, that is, pure cassava dregs or organic fertilizer fermented with cassava dregs and rice and wheat straws are obtained for future use.

[0035] Feeding: Weigh each raw material according to the composition and ...

Abstract

The invention relates to a biological type organic-inorganic compound fertilizer. The biological type organic-inorganic compound fertilizer comprises, by weight, 30-37 parts of organic fertilizers, 10-15 parts of urea, 20-25 parts of ammonium chloride, 5-5.5 parts of ammonium sulfate, 10-20 parts of monoammonium phosphate, 10-12 parts of calcium superphosphate, 10-15 parts of potassium chloride and 0.1-0.12 part of arbuscular mycorrhizal fungal inoculants. According to the technical scheme, the biological type organic-inorganic compound fertilizer has the advantages that the biological type organic-inorganic compound fertilizer manufactured by the aid of the arbuscular mycorrhizal fungal inoculants is high in utilization rate, convenient to use, wide in practicality and widely applicable to different types of soil and is environmental friendly.

Description

technical field [0001] The invention relates to the field of agricultural production, in particular to an organic-inorganic compound fertilizer. Background technique [0002] At present, the problem of soil degradation is becoming more and more serious, mainly manifested as soil compaction and hardening, erosion, salinization, acidification, element imbalance, chemical pollution, loss of organic matter and degradation of flora and fauna, etc., which seriously limit the development of land productivity. Soil degradation caused by agricultural production activities is an important cause of land degradation. Extensive use of inorganic fertilizers leads to soil compaction, unreasonable irrigation causes soil salinization, and unreasonable use of pesticides leads to serious soil damage. These are the main reasons for the decline of soil fertility. . [0003] In order to solve the problems existing in the application process of conventional chemical fertilizers and pesticides, re...
