How to apply fertilizer to plant edible fungus

Correct fertilization is an important measure to seize the high yield of edible fungi and improve the quality of edible fungi. The function of fertilization is to supplement and adjust the nutritional components, eliminate harmful factors and create favorable conditions for the sustainable high yield of edible fungi. The fertilization of edible fungi can be divided into two aspects: culture material fertilization and bacteria bed fertilization.

1. Fertilization of culture materials at present, the water intake of cottonseed hulls is very low, and there is a lack of nutrition, so it is difficult to increase the yield without adding additional nutritions.This is the reason why many mushroom farmers report that the yield is much lower than before. The fertilizer in the culture material should be mainly organic fertilizer, and the amount of chemical fertilizer can be relatively less. The nutrition of organic fertilizer is comprehensive, which can provide omni-directional nutrition supply for the growth of edible fungus mycelium, especially in the later stage of mushroom emergence. The composition of chemical fertilizer is easy to be absorbed and utilized by mycelium, which can be combined with organic fertilizer. The organic fertilizers often used by edible fungi are livestock and poultry manure, bean cake, cotton cake, corn flour, wheat bran, rice bran and so on. According to the nitrogen content of raw materials, 10% to 30% can be added. Chemical fertilizers generally include potassium dihydrogen phosphate, magnesium sulfate, urea, compound fertilizer, special fertilizer for edible fungi, etc., with a general addition of 0.1% to 0.5%, which cannot be added too much, otherwise it will lead to poor mycelium growth.

The common ingredients of mushroom bed fertilization include edible fungus special micro-fertilizer, many plant growth hormones such as triacontanol, indole acetic acid, gibberellin, naphthylacetic acid, etc., self-made nutrient solutions such as compost extract, mushroom root soup, soybean milk juice, poultry dung juice, glucose calcium carbonate solution, urea or ammonium sulfate solution, protein yeast powder solution, plant ash solution and so on. The way of fertilization can be carried out by hole irrigation and furrow irrigation. the distance between holes can be 10 cm, and the distance between furrow irrigation is 30-50 cm. After filling fertilizer solution, the ventilation rate can be increased, and it can be irrigated again every 5-6 days.

Fruiting body fertilization is also one of the most commonly used methods at present, and the main nutrients used are mainly inorganic nutrients, such as special micro-fertilizer for edible fungi, urea solution, potassium dihydrogen phosphate solution, humic acid solution and so on. now the promotion and application of a lot of biological liquid fertilizer, such as Guangda king, Lixin king and so on, the application effect is also very obvious.
