Problems solved by technology

However, on the one hand, the process of screening and cultivating phosphorus-solubilizing microorganisms is cumbersome and costly, so adding phosphorus-solubilizing microorganisms will increase production costs, and the production conditions of biological phosphorus activators are relatively strict; on the other hand, the added solution It is difficult to ensure the biological activity of phosphorus microorganisms in specific and different soil environments, and cannot fully exert their biological phosphorus-di...

Abstract

The invention relates to a calcareous soil phosphorus activator and a preparation method and application thereof. The calcareous soil phosphorus activator comprises active ingredients including crop straws, coal ash, bentonite, humic acid, seaweed extract, organic acid, amino acid, phytase and the like. The calcareous soil phosphorus activator has the advantages that through physical and chemicalactions, phosphorus fixation of calcareous soil can be alleviated effectively, phosphorus fixed in the soil can be activated, unavailable phosphorus in the soil can be facilitated to be converted intoavailable phosphorus, and accordingly the calcareous soil phosphorus activator is widely applicable to the calcareous soil in different areas; in a process of activating a soil phosphorus nutrient after being applied into the soil, the calcareous soil phosphorus activator can also facilitate soil phosphorus nutrient absorbing of crops, can enhance fertilizer efficiency of a fertilizer when beingapplied together with the fertilizer, and can increase output and quality of the crops.

Description

technical field [0001] The invention relates to the technical field of soil improvers, in particular to a phosphorus activator for calcareous soil and its preparation method and application. Background technique [0002] Phosphorus is one of the indispensable nutrient elements for plant growth and development, and plays an important role in high crop yield, improving crop stress resistance and adaptability. Calcareous soil, also known as alkaline soil, is a general term for soil containing free calcium carbonate. It is ubiquitous in arid and semi-arid regions. Due to factors such as high pH value, low electrical conductivity, and low organic matter in calcareous soil, most of the phosphate fertilizer applied to the soil combines with calcium in the soil to form insoluble phosphate. Due to the strong fixation of phosphorus by the soil, the available phosphorus content in the soil is low, and the seasonal utilization rate of phosphorus fertilizer is generally only 10% to 20%...
