Spring wheat management advice
First, the buckwheat is planted to promote the early growth of wheat. Generally, wheat fields advocate shallow and fine strokes, but windy weather should stop. For wheat fields with more dry leaves, it is necessary to clear the wheat ridges to increase the ground temperature and promote the increase of wheat tillers.
Second, according to local conditions, use the first fertilizer. First, for the wheat fields with sufficient base fertilizer, fertile soil, strong ability to protect the sputum and sufficient sensation, the first fertilizer should be postponed to the jointing stage. The second is that the base fertilizer is moderate, the ground force is moderate, the sensation is moderate, and the small wheat field can be properly managed early, and the first fertilizer water is implemented before the unfolding period. The third is the lack of primer, weaker fertilizer, faster loss, and smaller group before winter.
The amount of topdressing: the amount of pure nitrogen in high-yield fields is about 7-10 kg; the amount of pure nitrogen in middle-field is about 6-8 kg; the amount of pure nitrogen in low-yield fields is about 5-6 kg. The amount of fertilization is appropriately reduced by the high ground force, and the amount of fertilization is appropriately increased by the low ground force. Timely measurement and reporting to prevent pests and diseases. Prevention and control of pests and diseases is an important part of capturing the harvest of summer crops this year. Chemical weeding should focus on prevention and control during the regreening period. When using herbicides, fungicides can be added to prevent and cure root diseases. Pest control should strengthen forecasting and forecasting, and strive to minimize pest and disease losses.
