Five suggestions for wheat wintering science management
Winter wheat fields need to be adapted to local conditions, classified and scientifically managed.
Five suggestions on the scientific management of wheat wintering:
Replenish fertilizer and promote the transformation of seedlings.
For late sowing and looting, the wheat seedlings that affect the growth of wheat seedlings before winter are insufficient for the tillering before winter, and the sowing amount is increased in late evening. Although the population is large, the individuals are small, and the weak seedlings with fewer secondary roots, if no remedial measures are taken. Will seriously affect the formation of mass and yield. For the field where the base fertilizer is insufficiently applied or the sowing date is too late, fertilization should be applied early to promote the transformation of the seedlings.
Due to the rainy autumn, there will be a knot in the wheat field. The cultivating has the functions of breaking the knot, protecting the drought, increasing the ground temperature, promoting the growth, controlling the roots and controlling the weeding. During the rain, the wheat should be cultivated after irrigation. In particular, late-planting wheat should be carried out in a timely manner, and it is necessary to prevent the root system and bury the wheat seedlings. For the early seedlings, it is necessary to cultivate the roots and limit the growth.
Doing a good job of winter irrigation is an important part of wheat winter management. With the implementation of straw returning technology in place, if there is no timely suppression after sowing, early winter irrigation should be carried out to prevent cold air from entering the soil and harming the root system. The role is to effectively prevent the occurrence of suspended roots and freezing damage. In the case of persistent drought and severe soil moisture, we should actively resist drought irrigation to ensure that wheat seedlings grow robustly. Where there is no irrigation, it is necessary to suppress the protection in time to prevent prolonged growth.
Pay attention to prevent prosperous.
When the autumn rainwater can not be planted once, some wheat fields that are planted early will be prone to the problem of seedlings due to the high temperature in winter. It is not only bad for the development of young ears, but also causes the ear to be light and small, and also increases the risk of lodging and freezing damage. Some field plots should actively adopt field management measures to control the long-term.
Grasp the prevention and control of pests and diseases.
In the process of prevention and control of pests and diseases, we must adhere to the basic principles of comprehensive prevention and prevention, and do a good job in monitoring pests and diseases. Once we find that we need timely prevention and control, we must control the pathogen center and pest center to prevent spread. Experts remind that when using pesticides, please do not use drugs according to experience. It is necessary to strictly use and operate according to the pesticide instructions.
