Late sowing of wheat and even the fall of wheat, it is likely to cause pre-winter wheat seedlings overall weak, small, serious wheat problems, complex seedlings. Wheat seedlings are weak, have less accumulation of nutrients in the body, and have weak cold resistance and antifreeze. They are susceptible to freezing and chilling in winter and spring. Therefore, comprehensive measures must be taken to improve the management of late wheat cultivars before winter and winter so as to ensure late seeding. Safe winter wheat.

Prevention of pests, diseases and pests before winter, such as wheat root disease, underground pests, and autumn fleas found at the seedling stage, especially for wheat fields that have not been coated with seed or with seed dressings or soil treatments, should be promptly taken. Root and spray control measures. The removal of wheat can be carried out in the fall or early spring. It is better to have good chemical and weed control efficacy in autumn, and the safety is high. The period is 3 to 5 leaf phases of wheat, 2 to 4 leaf phases of weeds, and sunny days above 5°C.

Winter watering needs to be improved. Straw returning to the field starts after the wintering water moves to the 3-leaf stage and ends before the freezing and eliminating. The annual watering volume per mu is 30 to 40 square meters. It is worth noting that the weak seedlings in late sowing, especially the frost fall After sowing wheat, generally do not dry winter irrigation, so as not to reduce the temperature, affect the emergence of seedlings.

To strengthen the field of cultivating and management of wheat in the winter before the short growing period, the accumulated temperature is less, prone to small seedlings, leaves, less secondary roots, tillers do not occur or occur less. Therefore, the management should be based on the principle of keeping warm and keeping warm, to promote the early emergence of wheat seedlings, the last time rounding or smashing before freezing, should pay attention to soil swaying roots, or cover "moncler head", can protect the wheat seedlings safe winter. At the same time, it is strictly forbidden to grazing indigo in late summer wheat fields.

Freeze Dried Button Mushroom

Dehydrated shiitake mushrooms are food made from mushrooms. The technological process is raw material selection → drying → drying → grading packaging → finished product.
Material selection: The dried shiitake mushrooms should be moderately mature, complete, free of disease, insects and injuries. Generally, the mushrooms are harvested when the mushrooms are mature.
Drying: After harvesting, the mushrooms are placed on the drying sieve with the stem facing down, and placed in the sun to dry. The time depends on the moisture content of the raw materials, generally 5-8 hours.
Drying: Drying can be done in a drying room or in a dryer. Temperature control in drying stage.

Grading: The dried shiitake mushrooms should be graded in time. The grading standard can be carried out according to the size, color and integrity. Pick out the green mushrooms and re-dry them. After grading, put it into a plastic bag and seal it in time. The specifications of the plastic bag are determined according to the market demand.
