Special fertilizer for cultivating edible mushroom, prepn. method and application thereof

Abstract

The invention provides a special fertilizer for edible fungus cultivation and its preparation and application. Specifically, the special fertilizer for edible mushroom cultivation is composed of: 25 parts of plant ash water extract, 1-2 parts of superphosphate, 1-2 parts of gypsum powder, 0.05-1 part of glucose or sucrose, 0.1-0.5 parts of urea, potassium dihydrogen phosphate 0.05 to 0.5 parts. The preparation process is as follows: 1) the plant ash water infusion is to soak the plant ash and water in a ratio of 5-15:100 by weight, and the soaking time is 12-24 hours, and filter to obtain the juice after soaking; 2) superphosphate, gypsum powder , glucose or sucrose, urea, and potassium dihydrogen phosphate are weighed according to the corresponding amount, put into the plant ash water infusion of 1) and stirred, fully dissolved or uniformly distributed. Sprinkle evenly in the cultivation material when applying. The special fertilizer provided by the invention has more comprehensive nutrition, reasonable formula, easy-to-obtain raw materials, low cost, low investment and high application effect, and is an ideal fertilizer for the production of edible fungi.

Description

technical field [0001] The invention relates to edible fungus cultivation technology, in particular to a special fertilizer for edible fungus cultivation and its preparation and application. Background technique [0002] Edible mushrooms are rich in nutrition, high in protein, low in fat, and delicious in taste, and many other advantages are gradually being recognized by people, and they have become a health food that people like to eat. At present, the market demand is very large, and the production scale continues to expand, but there are problems in production. Many, the most important of which are low yield, low biological efficiency, and poor benefit; in order to improve biological efficiency, increase yield, increase economic benefits, promote the growth of mycelium in the cultivation material, and early fruiting, it must be added to the cultivation material Nutrition—fertilizer, which enriches the nutrients in the cultivation material, balances the various nutrients r...

Problems solved by technology

[0002] Edible mushrooms are rich in nutrition, high in protein, low in fat, and delicious in taste, and many other advantages are gradually being recognized by people, and they have become a health food that people like to eat. At present, the market demand is very large, and the production scale continues to expand, but there are problems in production. Many, the most important of which are low yield, low biological efficiency, and poor benefit; in order to improve biological efficiency, increase yield, increase economic benefits, promote the growth of mycelium in the cultivation material, and early fruiting, it must be added to the cultivation material Nutrition—fertilizer, which enriches the nutrients in the cultivation material, balances the various nutrients required for the growth of mycelium and fruiting, and coordinates the proportion; the fertilizer formula currently used to supplement the cultivation of edible fungi mainly focuses on nitrogen, phosphorus, and calcium , sulfur and other nutrient elements, while ignoring the supply of other necessary nutrients and trace elements; although the cultivation materials contain carbon, nitrogen, phosphorus, potassium and other macroelements and some trace elements required for the growth of mycelium, but the bacteria are sown It takes a period of time (5-7 days) before it can be released and used by mycelium growth, and some nutrients are insufficient, so the early growth of mycelium is obviously inhibited, the early growth of mycelium is slow, and it is easy to be invaded by miscellaneous bacteria. Dyeing will cause cultivation failure or slow growth of bacteria and slow fruiting. In the late growth period (generally after the third tide mushroom), the nutrient supply will be insufficient and the yield will decrease. Therefore, it is necessary to apply nutrient fertilizers to the culture material.

At present, there is an "edible fungus production-increasing additive" whose formula is "5 catties of fresh plant ash (preferably all kinds of bean straw ash), 2 catties of superphosphate, and 55 catties of water." In this formula, only superphosphate, potassium fertilizer and The role of other trace elements, while ignoring other nutrients and dosages during mycelium growth and mushroom production. The effect of mushroom early has certain limitations
