Method for preparing special fertilizer in paddy field

Abstract

The invention discloses a method for preparing a special fertilizer in a paddy field. The method comprises the following steps: stirring and uniformly mixing wormcast, rice husk, shredded rice straws and maize straws, calcium superphosphate and a microorganism inoculant, fermenting and composting for 7-12 days, and mixing with a lumbrukinase stock solution. Rice belongs to a silicophilic crop, the rice straws and maize straws contain lots of trace element silicon, silicon dioxide which is easily absorbed by rice is formed after fermentation, the wormcast and maize straws contain rich organic matters, nitrogen, phosphorus, potassium, trace elements and beneficial microorganisms, the soil can be activated, the soil properties are improved, the soil fertility is improved, the nutrient needed by rice production is met, and the problem that modern agricultural soil is damaged is solved.

Description

technical field [0001] The invention relates to a preparation method of a special fertilizer for paddy fields. Background technique [0002] With the increase of rice planting years, the nutrient deficiency in the soil of paddy fields has become more and more serious, and it can no longer meet the needs of rice growth and development. In order to ensure or even increase the yield, farmers use a large amount of chemical fertilizers and pesticides in paddy fields, resulting in physical and chemical damage to the soil. Character changes, soil compaction occurs, and nutrients are lost in large quantities. There is less and less high-quality soil in rice fields, and then more chemical fertilizers and pesticides will be used to maintain rice production, forming a vicious circle, which not only increases the production cost of rice. , also destroyed the soil ecological balance. [0003] Vermicompost is a kind of nutrient-rich agricultural production waste, which has good air perme...
