Compound manure fertilizer and preparation method thereof

Abstract

The invention discloses a compound manure fertilizer and a preparation method thereof. The compound manure fertilizer is composed of raw materials including, by weight part, 50-60 parts of human manure, 30-40 parts of chicken manure, 10-15 parts of urea, 5-10 parts of phosphate fertilizer, 15-20 parts of vermiculite, 3-5 parts of camphor, 15-20 parts of humic acid, 2-3 parts of pericarpium papaveris powder, 3-5 parts of biological microbial agent, 2-3 parts of chlorpyrifos, 2-3 parts of abamectin, 80-100 parts of auxiliaries and 6-10 parts of decomposition accelerant. The compound manure fertilizer is comprehensive in fertilizer efficiency and long in effective period and achieves the aim of killing pests and diseases in the compound manure fertilizer during high-temperature fermentation;the contained decomposition accelerant can promote decomposition of organic fertilizers and facilitate absorption by crops; additives are excellent in heat-conducting performance to avoid root corrosion due to a large amount of heat released by unfermented manure fertilizers.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a compound farmyard manure and a preparation method thereof. Background technique [0002] "Dung is strength, water is life", "Seventy-two farming is the first, and the garden fertilizer of a hundred acres is the first." With the transformation of agricultural production from output-based to quality-based, the quality of fertilizers applied in the fields has been paid more and more attention. There are many kinds of farmyard manure, and the source is wide and the quantity is large, so it is convenient to obtain materials locally. The characteristic of organic fertilizer is that it contains more comprehensive nutrients and appropriate proportions. It not only contains nitrogen, phosphorus, and potassium, but also contains calcium, magnesium, sulfur, iron, and some trace elements. Most of these nutrients are in the state of organic matter, which must undergo chemical and physical actio...

AI Technical Summary

Problems solved by technology

[0003] However, farmyard manure must be decomposed before it can be applied.

"Unripe farmyard manure has many problems after use. 1. Unripe farmyard manure often contains a large number of germ and insect eggs, which is easy to cause root diseases and insect pests, and also pollutes the environment; 2. Unripe farmyard manure contains nutrients. Most of them are in an organic state and are not easily absorbed by plants, which will cause fertilizer loss; 3. When farmyard manure is decomposed and fermented by microorganisms in the soil, it will generate a lot of heat, which is easy to burn the capillary roots of plants. 4. Farmyard manure in the soil During microbial decomposition and fermentation, a large amount of nitrogen will be absorbed, resulting in short-term nitrogen deficiency in plants; 5. Farmyard manure needs a process to undergo microbial decomposition and fermentation in the soil, resulting in a lag in fertilizer efficiency, which is difficult to match with the plant growth rhythm and fertilizer demand period , can not achieve the purpose of fertilization, and even cause adverse effects
