Abstract

The invention discloses a pleurotus eryngii culture medium based on material particle granularity collocation and a preparation method of the pleurotus eryngii culture medium. The culture medium comprises components in parts by weight as follows: 20-30 parts of sawdust, 15-25 parts of corncobs, 15-20 parts of bagasse, 5-15 parts of soybean meal, 10-20 parts of corn kernels, 10-20 parts of wheat kernels, 1 part of calcium carbonate and 1 part of lime powder, wherein the particle diameter of the sawdust is lower than 0.1 mm; the particle diameter of the corncobs is lower than 6 mm, and the corncobs lower than 40 meshes account for less than 15% of the total amount of the corncobs in mass ratio; the length of the bagasse is less than 5 mm; the granularity of the soybean meal is 5-40 meshes; the granularity of the corn kernels is 2-4 mm; the granularity of the wheat kernels is natural; the granularity of the calcium carbonate is lower than 60 meshes; and the granularity of the lime powder is lower than 60 meshes. According to the culture medium, compared with a conventional formula, the mycelium culture period is shortened by 18%, mycelia are denser and stronger, the fruiting period is shortened by 5%, and the output is increased by 5.5% stably.

Description

technical field [0001] The invention relates to a Pleurotus eryngii culture medium and a preparation method thereof, in particular to a Pleurotus eryngii culture medium based on material particle size matching and a preparation method thereof. Background technique [0002] Pleurotus eryngii is a kind of rare edible fungus that has developed rapidly this year, especially in factory facility cultivation. The cultivation cycle and yield quality of Pleurotus eryngii are closely related to the formula, not only to the nutritional index but also to the physical state of the compost. Therefore, it is very important to choose suitable materials. At the same time, the particle size of the selected materials and the relationship between them Reasonable collocation is equally important, which directly affects the biotransformation rate of materials and thus affects the yield and quality. The main research of the invention is the material type, particle size and collocation relationshi...
