Mixed culture base material for pleurotus eryngii culture

Abstract

The invention discloses a mixed culture base material for pleurotus eryngii culture. The base material comprises the following components in parts by weight: 3 to 5 parts of nutritional inorganic fertilizer, 60 to 70 parts of weed tree sawdust, 20 to 90 parts of oat husk, 10 to 40 parts of wood bran, 10 to 40 parts of peanut shell, 5 to 15 parts of cotton seed husk, 26 to 30 parts of calcium carbonate, 35 to 40 parts of corn core, 10 to 20 parts of sugarcane dreg, 15 to 25 parts of wheat bran, 3 to 8 parts of corn flour, 20 to 30 parts of calcium sulfate, 5 to 10 parts of magnesium sulfate, 5 to 10 pats of lime, 0.25 to 4 parts of gypsum, 5 to 10 parts of urea with a nitrogen content of 46%, 5 to 10 parts of triacontanol, and 2 to 7 parts of soybean meal. The water content of the mixed culture material after pre-wetting is 65% + / - 1%, and the pH value is 7.5 to 9. The nutritional inorganic fertilizer is a boron-potassium mixed fertilizer, and the mass ratio of boron fertilizer to potassium fertilizer is 1:1.5. The provided mixed culture base material is rich in nutrients such as vitamin B1, vitamin B, crude fiber, proteins, mineral substances, trace elements, and the like, and is beneficial for the growth of edible fungi. The edible fungi cultured by the provided mixed culture base material have a fresh and sweet flavor and a crispy and smooth taste.

Description

technical field [0001] The invention belongs to the technical field of edible fungus cultivation, in particular to a mixed culture medium for Pleurotus eryngii cultivation. Background technique [0002] At present, people generally use cottonseed husks as raw materials to cultivate edible fungi. The content of cottonseed husks in this type of edible fungi cultivation material accounts for 50%-90% of the entire edible fungus cultivation material. The nutrition contained in cottonseed husks is more suitable for consumption. However, due to the decline in cotton prices in recent years, the planting area has decreased year by year, resulting in a large increase in the price of cottonseed husks, and high cultivation costs for edible fungi; however, although edible fungi cultivated with cottonseed husks as the main material can be harvested 2-3 times, but the sum of the second and third yields is far less than the first yield, and the yield of edible fungi is unstable; in addition...

Problems solved by technology

[0002] At present, people generally use cottonseed husk as raw material to cultivate edible fungi, and the content of cottonseed husk in this kind of edible fungi cultivation material accounts for 50% %-90%, the nutrition contained in cottonseed shells is more suitable for the growth of edible fungi, but in recent years, due to the decline in cotton prices, the planting area has decreased year by year, resulting in a large increase in the price of cottonseed shells, and high cultivation costs for edible fungi; However, although edible fungi cultivated with cottonseed hulls as the main material can be harvested 2-3 times, the sum of the second and third yields is far less than the first yield, and the yield of edible fungi is unstable; in addition, cottonseed The shell contains a small amount of gossypol, and the peculiar gossypol smell in the cottonseed shell reduces the crude fiber content in the edible fungi. The produced edible fungi have certain defects in color, taste and flavor, and the quality of the edible fungi is not high.
