Excretion fermented seedling compound fertilizer and preparation method thereof

Abstract

The invention discloses an excretion fermented seedling compound fertilizer. The compound fertilizer is prepared from the following raw materials in parts by weight: 500-600 parts of livestock excretion, 120-140 parts of water hyacinth powder, 100-120 parts of castor stems, 100-120 parts of silkworm excrement, 100-120 parts of corn stalk, 80-90 parts of cottonseed cake, 40-50 parts of tobacco stems, 30-40 parts of pulverized fuel ash, 12-15 parts of river sand, 20-25 parts of calcium superphosphate, 15-20 parts of urea, 8-12 parts of potassium chloride, 1-2 parts of compound sodium nitrophenolate, 2-3 parts of copper sulfate, 6-9 parts of EM (effective microorganism) bactericide, 5-7 parts of microbial starter, 10-15 parts of soil conditioner, and a proper amount of water. The fertilizer adopts livestock excretion and the like as main raw materials through microbial fermentation, is rich in organic fertilizer, inorganic fertilizer and various nutrition, does not have toxic or side effect, does not pollute environment, can remarkably supply nutrition required by seedlings, can improve the soil structure, promote growth and development of seedlings, and improve the resilience of disease resistance, insect resistance, drought resistance, water logging resistance, cold resistance, salt alkali resistance, lodging resistance and the like.

Description

technical field

[0001] The invention relates to the technical field of fertilizers, in particular to a seedling compound fertilizer fermented with manure and a preparation method thereof. Background technique

[0002] The extensive application of chemical fertilizers has both advantages and disadvantages for human beings. Due to the unreasonable structure of fertilization in the process of agricultural production in our country, the current situation of biased application of chemical fertilizers and neglect of organic fertilizer application not only reduces soil productivity and quality of agricultural products, but also greatly damages the ecological environment. . In order to prosper and eliminate disadvantages, scientists have proposed "ecological agriculture" to gradually realize the use of less or no chemical fertilizers. Therefore, the significance of how to use agricultural organic waste reasonably and effectively is not only to make full use of the resources themselv...
