What is the function of the morel foreign aid nutrition bag?
The foreign aid nutrition bag is shaped like a cultivar culture bag. There is no inoculation of bacteria in the bag. Its function is to supplement nutrition for the hyphae, promote the formation of a large number of primordia and increase the number of sclerotia.
Nutrition bag raw material ratio: 48% wheat grains, 30% sawdust (or corncob), 10% cottonseed hulls, 10% wheat bran, 1% lime, 1% gypsum, moisture content 50% to 55%. Each bag contains 500g of wet material, sterilized by high temperature.
7 to 10 days after sowing, when the hyphae on the border turn white and conidia appear, a nutrient bag is placed. Use a screwdriver to poke 10 to 15 holes on one side of the nutrition bag. Place the bag with the holes facing down so that the nutrition bag is close to the border surface. Nutritional bags are placed horizontally 10 cm away from the edge of the border. Each border is placed in 3 rows at equal distances. The vertical spacing between nutrition bags is 40 cm. When placing, you need to press it so that all the holes are in contact with the soil and not exposed to the air to prevent contamination by miscellaneous bacteria.
After the foreign aid nutrition bag is placed, the morel mycelium gradually extends from the soil into the bag. After the hyphae are connected, the nutrition bag and the soil are tightly connected. After the nutrient bag has been placed for 40 to 50 days, the conidia on the ground begin to subside, the border surface turns yellow, the nutrient bag dries up and shrinks, and the nutrient bag is removed when touched, and the nutrient bag is ready for fruiting management. If the nutrition bag is not shriveled or shriveled when the border turns yellow, and the contact is still very close and difficult to separate, you do not need to remove the nutrition bag.
