Soil improving agent for soybean planting and preparation and use methods thereof

Abstract

The invention discloses a soil improving agent for soybean planting and a preparation method thereof, and belongs to the field of agricultural production. The soil improving agent is prepared by mixing plant ash, a nitrogen fertilizer, a phosphate fertilizer, biological manure, a nutrient solution and tedded sludge; the biological manure and the nutrient solution are obtained by the steps of carrying out mixed fermentation of animal dung, calcium oxide, calcined red mud, urea, vinasse, corn straw and peanut seedlings, and then filtering to obtain a filter residue being the biological manure and a filtrate being the nutrient solution. Through mixing of the specially-prepared biological manure with the plant ash, nitrogen fertilizer, phosphate fertilizer and other conventional fertilizers, the soil improving agent fully meets the needs of soil; moreover, the soil improving agent also contains the tedded sludge and the nutrient solution, further enhances the soil fertility, thereby improving the yield and quality of soybeans.

Description

technical field [0001] The invention relates to a soil improver used in the field of agricultural production, in particular to a soil improver for soybean planting and a preparation and use method thereof. Background technique [0002] Soybean is an annual herb whose seeds are also called soybeans. It is the most important legume in the world. The nutrients contained in soybeans are relatively comprehensive and rich in content. Most of the soybean fat is composed of unsaturated fatty acids, and its melting point is low. It is easy to digest and absorb, and is rich in linoleic acid and phospholipids, which are high-quality fats. Therefore, soybeans and soybean oil are often recommended as ideal foods for preventing and treating coronary heart disease, hypertension, atherosclerosis and other diseases. Northeast my country is the main soybean producing area in China. It is most commonly used to make various soybean products, extract soybean oil, brew soy sauce and extract pro...

AI Technical Summary

Problems solved by technology

[0003] my country is the origin of soybeans. The fertile land in the Northeast is the main producing area of ​​soybeans in my country. In the existing soybean cultivation, people simply apply some simple nitrogen, phosphorus, potassium and compound fertilizers regardless of the fertility of the land. There is a big problem with the way of fertilization. Due to the different degrees of soil fertility, if the amount applied is too small, it will lead to a decrease in soybean yield, and if it is too much, it may cause soil compaction, and even too barren land is not suitable for soybean planting at all.
