Physiological Diseases of Mushroom and its Control
Mushroom is more sensitive to the environment, poor cultivation environment, will hinder its normal growth and development, resulting in a variety of abnormal phenomena, resulting in the reduction of mushroom yield and quality. The common physiological diseases of mushroom are mycelium growing, hard umbrella opening, thin skin opening early or Pleurotus ostreatus, empty root Pleurotus ostreatus and so on. The introduction is as follows:
Overgrowth of hyphae
Symptoms: after the mushroom bed is covered with soil and transferred water, the mushroom villi hyphae will continue to grow to the fine soil surface, and in serious cases, a fine, impervious quilt will be formed, thus delaying the mushroom production and reducing the mushroom yield.
The cause: it is mainly due to the light and fast water transfer in the soil layer, the mushroom room temperature exceeding 22 degrees Celsius, humidity exceeding 90%, and poor ventilation.
Preventive measures: 1, try not to use aerial mycelium growth is too exuberant, too dense bacteria. 2. After covering the soil, the water transfer of the soil layer should not be too urgent, and the water spraying should be carried out when the weather is cool in the morning and evening. At the same time, the ventilation of the mushroom room should be increased and the air relative humidity should be reduced. 3. It is necessary to re-cover the soil immediately and spray more water appropriately to promote the mycelium to form a fruiting body in time, or gently rake the covered soil surface before the mushroom bud is formed, increase ventilation and reduce relative humidity.

How does the domestic geranium reproduce?
The most practical way to raise flowers in family is to use cuttings in pots. Cuttage time 4-5 months or 8-9 months is appropriate, should be determined according to the local temperature (18-20℃) growth season specific cutting time; culture soil to loose ventilation drainage, the best choice of sand, pearlite, rotting soil each a mixture, or coarse river sand, ripe soil or expanded pearlite, are required by the sun exposure and other methods of disinfection after application. Cuttings can be combined with spring and autumn pruning, choose a year without pests and diseases to develop healthy young shoots for cuttings, about 8 cm long, in the

Storage and fresh-keeping method of mushroom
Mushrooms are the best to eat fresh, but because they should not be kept for a long time in the natural environment, especially when mushrooms are cultivated in a large area, they can be exported to earn foreign exchange through storage and preservation, delayed sale or canned products. This paper introduces the storage and fresh-keeping technology of several kinds of mushrooms: 1. Cold storage. After finishing, the collected fresh mushrooms are placed in containers such as baskets, plaques or baskets and covered with multi-layer wet gauze or hemp bags. Put the jar in the shade, hold a small amount of water in the jar, place a wooden frame on the water, put the baskets and baskets containing fresh mushrooms on the wooden frame, and then seal the cylinder mouth with film.
