Special milk strawberry controlled release fertilizer produced by utilizing waste agaricus bisporus bracts and preparation method

Abstract

The invention discloses a special milk strawberry controlled release fertilizer produced by utilizing waste agaricus bisporus bracts. The controlled release fertilizer is mainly prepared from the following materials in parts by weight: 56-58 parts of waste agaricus bisporus bracts, 9-11 parts of perlite, 9-11 parts of silica, 0.6-0.7 part of water-retaining agent, 14-16 parts of sawdust, 9-11 parts of soybean bran, 9-11 parts of fishbone meal and 4-6 parts of slow release fertilizer. The controlled release fertilizer and the preparation method have the positive and beneficial effects that an approach for scientifically recycling the waste agaricus bisporus bracts is provided, thus promoting development of cyclic economy; quick lime is used for regulating the pH value and killing harmful bacteria in the waste agaricus bisporus bracts; the produced special controlled release fertilizer can achieve the effects of effectively reducing the usage amount of common compound fertilizers, increasing the contents of proteins and fatty acids in soil and obviously increasing the quality and yield of milk strawberries; and the obtained special controlled release fertilizer has good application effects and has the effect of increasing the granular structure of soil, thus loosening the soil and being beneficial to water and fertilizer retention.

Description

technical field [0001] The invention belongs to the technical field of slow-release and controlled-release fertilizers, and belongs to an organic biological fertilizer, in particular to a special controlled-release fertilizer for "milk strawberry" produced by using waste mushroom buds of Agaricus bisporus and a preparation method thereof. Background technique [0002] Commonly used fertilizers for planting Agaricus bisporus include five categories: manure, straw, cake fertilizer, chemical fertilizer, and minerals. The main ingredients are manure and straw (commonly known as dung forage) and contain a large amount of crude fiber, lignin and mycelium. However, after the cultivation of Agaricus bisporus, a large part of the waste mushroom buds cannot be effectively treated, and the number and types of miscellaneous bacteria increase sharply in a short period of time, resulting in increased acidity and metabolic toxins of the waste mushroom buds, and the light ones affect the sec...

AI Technical Summary

Problems solved by technology

However, after the cultivation of Agaricus bisporus, a large part of the waste mushroom buds cannot be effectively treated, and the number and types of miscellaneous bacteria increase sharply in a short period of time, resulting in increased acidity and metabolic toxins of the waste mushroom buds, and the light ones affect the secondary fruiting. Yield and quality, severe cases lead to a large number of reproduction and spread of pests and diseases

If the waste mushroom buds are directly applied to the field, it will cause a series of negative effects on the soil, such as the imbalance of acid-base balance, the growth of soil bacteria, and the imbalance of nutrient components, etc., causing huge pollution to the agricultural ecological environment.
