Straw mushroom substrate retting material for preventing soil from hardening

Abstract

The invention discloses a straw mushroom substrate retting material for preventing soil from hardening. The retting material is prepared by mixing and retting the following raw materials in percentage by weight: 70-90% of sundried straw, 10-30% of mixture of plant ash and potassium hydroxide. According to the invention, the raw materials are jointly soaked in water, in the soaking process, the pH value of a soaking liquid is not less than 12, and the raw materials are fished out after soaking for 1-3 days; the mixing weight ratio of plant ash to potassium hydroxide is 7:(0.8-1.2); the plant ash and potassium hydroxide are compatible scientifically instead of quick lime used when straw mushroom substrates are piled, thus avoiding the damage of soil hardening caused by the quick lime when straw mushroom is cultivated, and simultaneously, the retting material has the effect of preventing cucumber continuous cropping obstacle; and because the substrate does not contain the quick lime, a potassium ion which is brought into soil from the substrate can provide potassium nutrition for the next crop growth, thereby improving the disease resistance of the next crop, improving the quality of the next crop, increasing the yield of the next crop (taking cucumber for an example, the yield can be increased by more than 5%), reducing diseases (cucumber continuous cropping obstacle) and lowering the use of toxic pesticide.

Description

technical field [0001] The invention relates to the cultivation of edible fungi, in particular to the retting material of the compost of straw mushroom among the edible fungi. Background technique [0002] Using solar greenhouses or greenhouses to grow cucumbers against seasons has high economic benefits, and growing cucumbers in contiguous solar greenhouses or greenhouses has become a development trend of high-efficiency agriculture in some places. However, continuous cropping obstacles will occur when cucumbers are planted for three consecutive years, which will affect the yield and quality of cucumbers. In order to prevent the occurrence of cucumber continuous cropping obstacles, agricultural technicians have studied and promoted the "melon and mushroom rotation" planting mode, which can effectively prevent the occurrence of cucumber continuous cropping obstacles. [0003] Straw, corn stalks, cottonseed husks, etc. are used as compost for planting straw mushrooms. When m...

Problems solved by technology

However, in actual production, in order to speed up the softening of compost, the amount of quicklime is generally very large. Some farmers use about 30% of the weight of rice straw when retting compost, and some farmers use the amount of quicklime for retting rice straw. It can even reach 50% of the weight of rice straw, which makes the soaked straw highly alkaline, and when the straw is taken out, there is a lot of lime in it. Therefore, when planting straw mushrooms in a solar greenhouse or greenhouse, a lot of lime will Drench into the soil, thereby increasing the calcium content in the soil, making the pH value of the soil larger (increased alkalinity), causing soil compaction

Soil compaction will cause the quality of the next crop to deteriorate and the yield to decrease. For example, if cucumbers are planted, the yield of cucumbers will decrease by more than 10%.

On the other hand, the waste liquid after straw retting contains a large amount of quicklime, which will pollute the soil environment and soil water quality.
