Recently, a large grain grower said to Xiaobian: "In the past, when I planted two or three acres of grain, I didn't feel that it was too much trouble to grow grain. I found that there were too many doorways for the original grain! Which detail was ignored? It may cause a reduction in production! Now it is like raising a child, raising a seedling!" This big grain grower tells the voice of many people who grow grain: the scale of the grain has to be taken care of, can not ignore any management details!

 

Xiao Bian gave you eight suggestions for winter wheat management, I hope to help you!

 

First, pour the frozen water

 

        In order to ensure that winter wheat is safe for winter, it is necessary to timely pour the frozen water. It usually starts at a daily average temperature of 7-8 ° C and ends at around 5 °C. Winter irrigation generally suitable time is late November to early December. The amount of winter irrigation should not be too large, so that it can be poured through the day. After watering, it is necessary to plan in time to reduce evaporation, make up for cracks, eliminate weeds, and protect the seedlings from wintering. For early-wet long-term de-fertilization plots and three types of weak-bred crops, combined with winter irrigation, 5-10 kg of urea per acre can be applied , and winter fertilizer is used in spring. However, for a type of wheat field in Miaoduo, it is generally not fertilized, so as to avoid excessive tillering in the spring, and the group is too large, causing late lodging.

 

Second, the implementation of wheat control measures

 

        For the Miao Miao and the wheat fields with a long trend, especially the wheat fields with a main stem and leaf age of 7 or more and a group of more than 1 million are generally suppressed. Before the winter or the coming year, you can also spray inhibitors such as Zhuangfeng amine, and control is prosperous.

 

Third, before the winter plan

 

        It can break the knot, eliminate the weeds in the field, and can also maintain the temperature and promote the growth of roots and seedlings. Especially for late-season wheat, which is good in sensation and not ready to be poured with frozen water, it is necessary to carry out winter planning.

 

Fourth, winter crackdown

 

        The suppression of wheat fields can break down the soil, compact the soil, make up the cracks, prevent the death of wheat seedlings caused by surface cracks in winter, and reduce the number of wintering insects. In particular, after the sowing, the cracking effect is not good, the rotary tillage and straw returning to the field lead to the suspension of the soil and the extensive cultivation and landfill, and must be suppressed. After the suppression is frozen in the soil, it is carried out at noon from noon to 4 pm, usually 2-3 times.

 

Five, cover soil cover manure

 

        1. Cover the soil. When the wheat seedlings basically stop growing after winter ( before and after heavy snowfall ) , the wheat field, especially the late sowing wheat and the winter before the long wheat, should be broken and covered with soil, covering the soil about 2 cm, which plays a role of protection, heat preservation and cold protection. Prevent low temperature dead seedlings in winter.

 

        2. Cover the fertilizer. When planting, there is no rough or little wheat field. In case of conditions, a thick layer of fertilizer is added in winter to increase the surface temperature, protect the wheat seedlings, reduce the freezing damage, and improve the soil, so that the wheat seedlings will stabilize early in spring. long. It should be noted that the manure cover should be timely and generally controlled when the wheat seedlings stop growing. The cover soil cover prematurely affects the normal photosynthesis of wheat before winter, and the effect of keeping warm, keeping warm and preventing cold is too late.

 

Six, wheatgrazing is strictly prohibited

 

        Feeding wheat seedlings such as cattle and sheep will cause a large number of dead seedlings, resulting in different degrees of wheat yield reduction. Therefore, it is strictly forbidden to graze wheat fields.

 

7. Prevent and respond to natural disasters such as severe weather in a timely manner

 

        The weather forecast should be closely monitored. If there is a strong wind or a strong cold current, it is necessary to prevent the surface temperature and reduce the freezing damage by using firewood smoked smoke in the evening before the cold current.

 

Eight, pay close attention to pests and diseases

 

        Keep abreast of changes in the situation of pests and diseases, and prevent and treat them in early spring.
