Winter wheat is planted in winter and harvested in May. Spring wheat is planted in spring and harvested in July.
Matters needing attention in wheat planting:
First, pay attention to the choice of high-fat water plot. High-yield and high-quality wheat varieties need comprehensive and sufficient soil nutrients to meet the needs of high-yield cultivation. Therefore, it is advisable to choose plots with high soil fertility and good irrigation conditions, increase the application of organic fertilizer and adopt formula fertilization technology.
Second, pay attention to the appropriate late sowing and determine the appropriate basic seedlings according to the characteristics of varieties. It is necessary to prevent the broadcast volume from being too large, resulting in passive management in the later stage.
Third, pay attention to prevent lodging and re-apply jointing fertilizer. Some popularized high-quality wheat varieties are not resistant to lodging, especially in wheat fields with large population. Chemical control treatment must be carried out once before turning green and jointing, and paclobutrazol or Maiyefeng can be sprayed. It is necessary to supplement jointing fertilizer, control the formation of redundant inverted panicles, and promote large panicles and more grains.
Fourth, pay attention to watering slurry, wheat yellow water and spraying foliar fertilizer to prevent premature aging. Irrigation and grouting wells play an important role in increasing grain weight and preventing dry and hot wind. When the weather is dry, the application of wheat yellow water is beneficial to interplanting the next crop and preventing premature aging. Spraying 0.2% ~ 0.3% potassium dihydrogen phosphate and other foliar fertilizers for 2 ~ 3 times in the first half of May, combined with pest control, can reduce the harm of dry hot wind and obviously increase production.
Fifth, pay attention to the prevention and control of pests and diseases. Generally speaking, high-quality wheat is more prone to diseases and pests, such as wheat sheath blight and powdery mildew, and aphids occur earlier and heavier than conventional varieties. Should be based on the forecast, early prevention and control.
6. Spraying Maibao once just before heading and flowering of wheat is about 60-70% (as shown below), which can activate the biological enzyme activity in wheat, promote the development coordination of male and female organs, enhance the photosynthesis of functional leaves, obviously reduce the empty grain rate, improve the seed setting rate and 1000-grain weight, and thus achieve the effect of increasing production.
