Wheat is a staple food for the people of northern China. It has been an important food for nourishing the human body since ancient times. It is the most widely distributed food crop in the world. Its sown area is the crown of all kinds of food crops and it is one of the important foods. The nutritional value of wheat is very high, and the contained B vitamins and minerals are very beneficial to human health. So, how should winter wheat be managed? The four methods of winter wheat management are introduced for your reference.
Drought-free winter climate is dry, winter wheat fields are generally more severe drought, most of the wheat fields lack. Therefore, when the temperature rises, when the night is frozen, it is necessary to water in time to promote the growth of roots in the underground, and ensure the preservation of roots.
Winter field management of frost-proof winter wheat field should adhere to local conditions, classification guidance, in particular, to do a good job of antifreeze work, increase wheat resistance, lay a good foundation for the next year's high yield. First, the quality of the whole field is poor, and the large-scale hanging seedlings of the field can be applied with soil-fertilizer to cultivate soil, so as to play the role of freezing and seedling protection. Second, pouring frozen water, late sowing, seedlings deviation of the wheat field in time to cultivating loose soil, remove the hardening, increase the temperature, promote the weak and strong.
Disease prevention In general, about 15 days after wheat is sown, the wheat seedlings are basically grown. It is necessary to investigate the occurrence of diseases and pests in wheat. After 20 days of wheat emergence, rust, sheath blight, and full-blown rot can all be infected. When the rate reaches 10%, it can be sprayed and controlled.
The seedlings of Wangwang seedlings, which are formed by excessively long sowing seedlings, have excessive growth, poor individual development, and few tillers. The seedlings should be sparsely seedled and supplemented with fertilizer. Sparse seedlings can establish a suitable group structure and promote individual development. The sparse seedlings combined with watering supplemented with available nitrogen and phosphate fertilizers. Over-emphasis of fertilizer and water formed by vigorously growing seedlings of rice seedlings, large leaves, severe field closure. The roots should be severely squatted, squat 5 to 7 cm between rows of wheat fields, cut off some secondary roots, control the absorption of nutrients, suppress the occurrence of tillers, and cultivate strong seedlings.
The spring planting of spring wheat seedlings and weak spring wheat varieties that are formed due to improper selection of varieties will lead to prolonged winter prevalence and are prone to frost damage. On the basis of scratching and repression, roots were planted before winter and organic fertilizer was applied to protect the wheat seedlings from winter.
