[0014] An environment-friendly slow-release fertilizer for crops, made of the following raw materials in parts by weight (kg): organic fertilizer 20, enzyme 3, potassium hydrogen phosphate 8, magnesium sulfate 1, boric acid 1, molybdenum-containing calcium superphosphate 1, selenous acid Sodium 1, copper sulfate 1, garlic stem dry powder 2, castor leaf dry powder 2, hydroxypropyl methylcellulose 1, natural gelatin 1, waste engine oil 2.

Embodiment 2

[0016] An environment-friendly slow-release fertilizer for crops, made of the following raw materials in parts by weight (kg): organic fertilizer 24, enzyme 6, potassium hydrogen phosphate 10, magnesium sulfate 3, boric acid 3, molybdenum-containing calcium superphosphate 3, selenous acid Sodium 3, copper sulfate 3, garlic stem dry powder 4, castor leaf dry powder 4, hydroxypropyl methylcellulose 3, natural gelatin 3, waste engine oil 4.

Embodiment 3

[0018] An environment-friendly slow-release fertilizer for crops, made of the following raw materials in parts by weight (kg): organic fertilizer 23, enzyme 3, potassium hydrogen phosphate 8, magnesium sulfate 2, boric acid 2, molybdenum-containing calcium superphosphate 2, selenous acid Sodium 2, copper sulfate 1, garlic stem dry powder 2, castor leaf dry powder 3, hydroxypropyl methylcellulose 2, natural gelatin 2, waste engine oil 4.

[0019] The preparation steps of the environment-friendly crop slow-release fertilizer of the above three embodiments are as follows:

[0020] (1) Potassium hydrogen phosphate, magnesium sulfate, boric acid, calcium superphosphate containing molybdenum, sodium selenite, copper sulfate, garlic stem dry powder, castor leaf dry powder, and waste engine oil are mixed;

[0021] (2) adding natural gelatin to an appropriate amount of water, heating to 80-90°C, stirring evenly, then pouring it into the mixture obtained in step (1), after stirring, gra...

Abstract

The invention relates to an environment-friendly crop controlled release fertilizer and a preparation method thereof. The environment-friendly crop controlled release fertilizer is characterized by being prepared from, by weight, 20-24 parts of organic fertilizer, 3-6 parts of enzymes, 8-10 parts of potassium hydrogen phosphate, 1-3 parts of magnesium sulfate, 1-3 parts of boric acid, 1-3 parts of molybdenum-contained calcium superphosphate, 1-3 parts of sodium selenite, 1-3 parts of copper sulfate, 2-4 parts of garlic stem dry powder, 2-4 parts of castor leaf dry powder, 1-3 parts of hydroxy propyl methyl cellulose, 1-3 parts of natural gelatin and 2-4 parts of used oil. According to the formula, the hydroxy propyl methyl cellulose and the natural gelatin absorb water and expand to form a layer of permeable membrane to achieve the controlled release effect; the used oil perform enveloping on microelements to achieve the controlled release effect; combined with the garlic stem powder and the castor leaf powder, the effects of sterilization and plant disease and insect pest prevention are achieved; meanwhile, enzymes are added, soil microelements are supplemented for, crop growth and microelement absorption are promoted, the crop quality is improved, and human health is benefited. Compared with traditional fertilizer, the controlled release fertilizer is applied one time, no topdressing is adopted, the yield of crops such as wheat is increased by 15-20%, and meanwhile the soil can be improved.

Description

technical field [0001] The invention relates to a fertilizer, in particular to an environment-friendly slow-release fertilizer for crops and a preparation method thereof. Background technique [0002] In my country, wheat, corn, and rice are the main food crops. At present, the application of organic fertilizers to crops in my country is extensive, and a large amount of additional chemical fertilizers are required in the follow-up, resulting in increased labor costs and serious fertilizer loss. However, with the development of urbanization in our country, the main rural laborers are mainly working in cities, and the field management of crop planting mainly relies on the elderly and women. It is urgent to realize the mechanization and simplification of operations such as sowing, harvesting, and fertilization. Especially in terms of fertilization, the frequency of fertilization is too high, and a large amount of chemical fertilizers are used to reduce soil fertility. Therefo...
