Strengthen post-management to prevent premature aging of wheat
The premature aging of wheat is a phenomenon in which plants fail to mature and die prematurely. Premature aging can shorten the grain filling period and reduce the grain weight of wheat, resulting in a significant reduction in yield. There are many causes of premature aging of wheat. In our district, there are mainly drought stress, lack of nutrition, soil waterlogging, improper management, and pests and diseases. 1. Drought stress: Soil drought or atmospheric drought can easily lead to difficulty in water absorption or excessive water loss in the roots of the plant, causing the water balance to be destroyed, and normal physiological metabolism is inhibited. Especially in the late growth period of wheat, high temperatures, large amounts of soil evaporation, and evapotranspiration occur in the soil. If the soil is severely droughty, the root system cannot absorb water from the soil, causing plant wilting, grain filling can not proceed normally, the grain filling rate decreases, and the grain weight decreases. With the death of wheat, the grain filling period was greatly shortened, and the yield was greatly reduced. 2. Nutrition deficiency: In dry and thin soils, due to lack of nutrients in soil, photosynthetic processes such as wheat are affected. Especially in the late growth period of wheat, nutrients become scarce. As a result, the plants lose their nutrients because of lack of nutrients, the filling period is shortened, and the grain weight is reduced. 3. Soil waterlogging: Soil waterlogging leads to soil hypoxia, root respiration and absorption functions decline, aboveground chlorophyll degradation, photosynthetic capacity decline, and substance synthesis and accumulation decrease. 4. Improper management: If fertilizers and waters are improperly handled, the population in the early period is too large, the individuals are stunted, the soil nutrients are exhausted in the later period, the functional period of the upper leaves is shortened, and the plants are prematurely decayed. 5. Pest and harm: When diseases and pests occur in wheat fields, if they cannot be prevented or prevented in time, wheat diseases and insects will occur. A pandemic will also lead to premature aging of wheat and reduce grain weight. To prevent premature aging of wheat, we must take appropriate technical measures to address the causes of premature aging: 1. To strengthen the basic construction of farmland, do a good job of field water conservancy projects, and reduce the groundwater level so that the drought energy can be poured into the water. This is the fundamental way to prevent premature aging of wheat caused by drought and rain. 2, increase organic fertilizer, straw to return to the field, continue to fertilize the soil, combined with deep plowing to improve soil physical and chemical properties, and do a reasonable ratio of nitrogen, phosphorus and potassium, is to ensure the steady growth of wheat, to prevent premature aging material basis. 3, rational transport of fertilizer, early seedlings to promote seedlings, wheat seedlings cultivated before the winter, at the same time control the spring of invalid childbirth, establish a reasonable group structure, so that the growth of strong wheat without prostration, but also to prevent late defermentation, premature aging is an important measure. 4. Establish and improve the defense system for pests and diseases in wheat fields, do a good job in forecasting and comprehensive prevention and control of pests and diseases.
