How to ensure that wheat is safe for winter? Promoting root growth is the key
As soon as the wheat reaches the winter, farmers need to manage the wintering of wheat. This period is a very important period in the whole growth period of wheat. Once the management is negligent, there will be freezing death of wheat, and it is impossible to safely pass the wintering period. So, how can we ensure that wheat is safe for winter? Xiaobian teaches you the following methods today.
From the emergence of the wheat to the wintering period, the main stages are long roots, long leaves, tillers, and several stages of vernalization. On the basis of seedling protection, field management should pay attention to the promotion of root growth of wheat seedlings, turn weak seedlings into strong seedlings, grow strong seedlings, and ensure that wheat seedlings can safely overwinter.
1. Checking seedlings and replanting: Due to the lack of seed, stagnation, and underground pests, the fields lacking seedlings and ridges should be investigated in time for seedling replanting. The wheat seeds are soaked in cold water for 24 hours, dried and then sown to ensure full seedlings and even seedlings.
2. Prevention and control of pests and diseases: The pests of seedling diseases mainly include pests such as bandits, planthoppers, underground pests and leaf rust, which should be timely prevented.
3. Overwhelming needles: After the 3 leaf stage of wheat, the nutrients in the seed endosperm are exhausted, and the seedlings rely on photosynthesis to produce nutrients, which is a key period for promoting root growth. In the 3-leaf stage, it can be lightly suppressed once, and the main stem can be controlled to promote tillering and control the roots.
4, cultivating loose soil: rain in the tillering period, timely ploughing loose soil, breaking the knot, and promoting root growth. Wang Miaotian deep ploughing more than 7 cm, the roots are controlled; the saline-alkali land should be done after the rain to prevent salt return.
In fact, the cold tolerance and freezing ability of wheat are very good in crops, but the management during wintering period should also be done to ensure that wheat can safely pass the wintering period and can produce high yield in the later period.
