Recently, the large-scale snowfall in the north has brought inconvenience to our production and life. Although it is said that “Ruixue Zhaofeng Yearâ€, due to the premature snowfall this year, there is still a slight adverse effect on wheat.
Then the question comes, how to manage wheat after rain and snow?
Wheat is managed after rain and snow:
1. A strong seedling of the first class: in order to smooth down and suppress the weather after the weather is fine and the temperature rises. The current type of seedlings is in the three-leaf stage of wheat, and the three leaves of wheat will begin to divide with the accumulation of nutrients, that is, the common people are commonly known as "full moon", which produces secondary roots at the base of the stem. Divided into roots. It is also a key period for obtaining the number of effective spikes in the wheat field next year and creating a high-yield population.
At this time, the stroke can effectively increase the ground temperature by 3 to 5 °C, prompting the wheat to start branching early, and preventing the cold wave (wind and snow) from coming to avoid the occurrence of frost damage. The suppression of wheat fields can break down the soil, compact the soil, make up the cracks, and prevent the death of the roots of the wheat seedlings caused by the cracks in the surface of the wind and snow.
2, 2 or 3 types of wheat fields: After the weather warms up, you can use 5 ml of love to receive +40 grams of potassium dihydrogen phosphate or 30 ml of mountainous multi-master +15 grams of Hefeng boron or 3 grams of Bi-protection for a bucket of water. Spray, 5 to 7 days apart, preferably 2 to 3 times in a row.
3. Straw returning wheat field: It is necessary to suppress the wheat field in time. And after the temperature is warmed down after the suppression, you can spray 5 ml of water with 5 ml of love to receive +40 g of potassium dihydrogen phosphate or 30 ml of patrons +15 g of Hefeng boron, interval 5 to 7 days, continuous 2 to 3 The second time is better, free from freezing damage.
4, wheat field post-emergence weeding will soon enter the wheat field weeds Qiuzhi prevention and control section of wheat, buckwheat, looking at Mai Niang and broadleaf weeds. Due to the low temperature and the rainy weather in the past few days after planting wheat this year, the fine roots of the wheat seedlings are underdeveloped, and the overall resistance is poor. In addition, they have just suffered from rain and snow, and if the weeds are treated at this time, It is tantamount to "adding to the snow", which will have a serious impact on the tillering of wheat. Therefore, it is recommended to delay the prevention and treatment time properly. When the weather turns fine and the temperature rises, wait for the opportunity to spray the medicine. If the appropriate amount of the phytotoxicity regulator or foliar fertilizer is added when spraying the medicine, the yellowing or seedling phenomenon of the wheat seedlings can be well avoided, and the wheat field will return to the early morning, not premature aging, and the grain is full, which will lay a good foundation for high yield in the coming year. The basics.
