Cultivation of Edible Fungi requires rational allocation of Raw Materials

Since last year, the price of raw materials for edible mushroom cultivation has risen step by step, making many mushroom farmers wonder: with raw materials rising and mushroom prices falling, can we still grow mushrooms this year? In fact, as long as we adhere to the principle of "taking measures in accordance with local conditions", the goal of "braving the wind and waves and sitting firmly in a fishing boat" can be achieved. You don't believe me? See if what the author said is reasonable:

1. The current price of cottonseed shell has reached about 1.10 yuan per kilogram, which is about 40% higher than that of previous years. Together with the increase in the price of plastic bag materials, the production cost has increased by more than 50%, which is indeed a lot of pressure. However, everything is divided into two, cottonseed shell cultivation of edible fungi, obviously has the advantages of easy operation, fungus insurance, stable yield and other advantages, compared with, especially for the first time growers, the benefit is stable and reassuring. Basic formula: 250 kg of cottonseed shell, 5 kg of calcium superphosphate, 1 kg of urea, 3.5 kg of gypsum powder, 120 g of three-dimensional nutritional essence of edible fungi; 5 kg of lime powder was added when sowing from April to September.

two。 Because the corncob can be used as industrial raw materials such as xylitol and furfural, the price of corncob has doubled in recent years, from less than 0.10 yuan per kilogram a few years ago to about 0.50 yuan in the past two years, and the processing cost is about 0.10 yuan, which is not much different from that of cottonseed hulls. Its biological efficiency is about the same. Basic formula: 250kg corncob, 5kg soybean meal, 5kg lime powder, 2kg gypsum powder, 6kg calcium superphosphate, 1kg urea, 5 bags of mushroom disease, 120g three-dimensional nutritional essence of edible fungi (add and mix well after fermentation, the same below).

3. The raw material of bean straw is not very rich in Shandong and other inland resources, but there is a large quantity in Tai'an, Heze and other places. The nitrogen content of this raw material is the highest among all straw raw materials. The author has mixed it with corncob and the cultivation effect is very ideal. The basic formula is: corncob 100 kg, bean straw 150 kg, lime powder 5 kg, gypsum powder 2 kg, calcium superphosphate 6 kg, mushroom disease elimination 5 bags, edible fungus three-dimensional nutritional essence 120 grams.

4. Wheat straw and rice straw are mostly used in the cultivation of straw mushroom, double spore mushroom, Agaricus blazei Murrill and other varieties, but few are used in the production of Pleurotus ostreatus, hericium Erinaceus, etc., this is not to say that this material is not the best choice at least, especially Lentinus edodes, hericium Erinaceus, Auricularia auricula, etc. in wood rot fungi, the fungus time and mushroom emergence time are longer, as forage, its composition is mostly cellulose, and the lignin content is low. It is difficult to be decomposed by hyphae for a long time and keep it basically full of bags, so it is used to produce straw rot fungi as far as possible. The formula for cultivating Pleurotus ostreatus is as follows: 3000 kg of wheat straw or rice straw, 3000 kg of cow dung powder, 60 kg of calcium superphosphate, 60 kg of urea, 80 kg of lime powder, 80 kg of gypsum powder, 90 kg of calcium carbonate and 1440 g of three-dimensional nutritional essence of edible fungi (mixing type). The basic formula of cultivated straw mushroom is as follows: 225 kg of wheat straw or rice straw, 25 kg of wheat bran, 8 kg of superphosphate, 1.5 kg of urea, 12 kg of lime powder, 4 kg of gypsum powder, 5 bags of mushroom disease, and 120 g of three-dimensional nutritional essence of edible fungi.

5. The resources of peanut seedling, peanut shell and millet straw are relatively few, and wheat straw can be used for reference in production.

6. The raw material of cotton stalk is similar to sawdust, and contains a lot of phloem tissue, which is very beneficial to the mycelium growth of edible fungi. The author has used it as the cultivation material of Coprinus comatus, and the effect is very ideal. The vast majority of mushroom farmers are reluctant to use it because it is difficult to crush, and ordinary crushers can do nothing about it. They can only use wood chips to cut it up mechanically before it can be broken. According to research, most farmers burn it as firewood, which is a great pity. The formula of cultivated Pleurotus ostreatus and Coprinus comatus: 220 kg of cotton stalk powder (less than 0.5 cm), 30 kg of wheat bran, 3 kg of ternary compound fertilizer, 10 kg of lime powder, 5 kg of gypsum powder, 5 bags of mushroom disease, 120 g of three-dimensional nutritional essence of edible fungi. When used in the cultivation of Lentinus edodes, it can be treated as sawdust for formula. However, most of the current cotton varieties are genetically modified, so products cultivated with cotton stalk powder can not be used for export.
