Soil conditioner

Abstract

The invention relates to a soil conditioner. The soil conditioner contains Brevibacillus laterosporus and Streptomyces fradiae; the metabolites are zeatin (Z, ZR, IPA and diHZ), auxin (IAA), gibberellin (GA3) and abscisic acid (ABA); and the content of Brevibacillus laterosporus is 0.20-1.5 billion per gram and the content of Streptomyces fradiae is 0.20-1.5 billion per gram. By adopting the soil conditioner, the dosage of fertilizer can be reduced, the environmental pollutions can be reduced, soil compaction can be eliminated, the crop can have high yield and high quality, and the production is efficient.

Description

technical field [0001] The present invention relates to a soil conditioner. [0002] Background technique [0003] my country is a country with a large population and a large agriculture. It uses 7% of the world's land to feed 22% of the world's population. The food issue is always a major issue related to the national economy and people's livelihood. my country has 2 billion mu of arable land and needs 150 million tons of fertilizers annually. It is the world's largest importer of fertilizers and producer of nitrogen fertilizers. Even so, the amount of chemical fertilizers still cannot meet the needs of agricultural development. The reason is that the key problem is that the utilization rate of chemical fertilizers is too low. According to the calculations of the research department, the average utilization rate of nitrogen fertilizer across the country is 30-35%, 20-30% of phosphorus fertilizer, and 30-50% of potassium fertilizer. It is estimated that about 1 million t...
