Base fertilizer adapting to improvement of soil in protected areas and preparation method thereof

Abstract

The invention belongs to the technical fields of fertilizers and fertilizer manufacturing, and discloses a base fertilizer adapting to improvement of soil in protected areas and a preparation method thereof. The base fertilizer comprises the raw materials by mass: 10-30 parts of fresh chicken manure and cow manure, 30-50 parts of coconut bran, 10-15 parts of humic acid, 10-15 parts of shell powder, 10-15 parts of clay, 15-20 parts of corn cobs, 10-15 parts of wheat bran, 10-15 parts of bagasse, 8-10 parts of quicklime, 0.3-0.6 part of borax, 0.8-1.0 part of ferrous sulfate, 0.3-0.6 part of zinc sulfate, 0.3-0.6 part of magnesium sulfate, 0.2-0.5 part of bacillus subtilis, and 0.2-0.4 part of an insecticide. The problem of soil acidification is effectively alleviated, the problems of soil salinization and compaction are effectively solved, the disease resistance effect of the soil is enhanced, the damage of plants caused by insect pests in the soil is effectively prevented, and with addition of a certain amount of coconut bran, the soil permeability, water and fertilizer conservation capacity are improved, and the land can be also effectively protected.

Description

technical field [0001] The invention belongs to the technical field of fertilizers and fertilizer manufacturing, and in particular relates to a base fertilizer suitable for soil improvement in protected areas and a preparation method thereof. Background technique [0002] At present, the existing technology commonly used in the industry is as follows: due to years of continuous cropping in protected areas, long-term use of acidic fertilizers such as superphosphate, and excessive use of nitrogen fertilizers, reducing the amount of organic fertilizers, resulting in a large accumulation of nitrate nitrogen and poor soil buffering properties. The soil is severely acidified and compacted, and at the same time, unreasonable irrigation causes excessive accumulation of salt, which affects the growth of roots and plants. [0003] In summary, the problems in the prior art are: long-term use of acidic fertilizers such as superphosphate and excessive use of nitrogen fertilizers lead to ...

AI Technical Summary

Problems solved by technology

[0003] In summary, the problems in the prior art are: long-term use of acidic fertilizers such as superphosphate and excessive use of nitrogen fertilizers lead to poor soil buffering properties, resulting in severe acidification and compaction of the soil, and at the same time, unreasonable irrigation causes excessive accumulation of salt, affecting root system and plant growth.
