AI Technical Summary

Technical Problem

When peanuts are grown in red and yellow soil areas in the south, poor soil calcium results in a large number of empty fields. The existing application of calcium-containing materials such as shell powder has dust problems, burn risks, and low utilization rates, which limits the effectiveness and promotion of preventing and controlling empty fields.

Method used

Shell powder and weathered coal are used as raw materials, and granular calcium materials are produced through the agglomeration and granulation process to form peanut treatment materials rich in calcium and organic matter. Combined with other nutrients, it reduces raw material costs and improves the product's cost performance.

Benefits of technology

Effectively prevent and control peanut emptying, improve peanut yield and quality, promote the recycling of agricultural waste resources, reduce resource waste, and improve application efficiency and economic benefits.

Abstract

The inventive technique process of grainy calcium material for preventing and treating peanut blight primarily includes: adopting the shell powder and weathered coal as raw materials, machining into peanut blight prevention material through agglomeration granulation. The invention has innovative and reasonable design, which not only has simple process, easy implementing, but also has low cost of raw materials, product application convenience, remarkable peanut blight prevention effect, and capability of promoting high-efficient production pf peanut. In particular, the invention applies coastal oyster shell wastes for machining calcium materials for preventing and treating peanut blight, which not only reduces environmental pollution, but also promotes recycling of resources, has very significant economic, social and ecological benefits and greater promotional value.
