The planting technology of this crop

This crop can grow well in acidic and slightly alkaline soil, but the most suitable soil pH value is pH6.5 to 7.5.

Tillage and soil preparation

The soil preparation of this crop in dry land should be based on increasing the deep ploughing layer year by year, combined with increasing the application of organic fertilizer and improving water-retaining fertilizer, according to different multiple cropping forms. That is to say, if the previous crops are harvested earlier, such as spring corn, sorghum, tobacco and so on. Clean up the stubble first, then dig the kang soil deeply, let the stubble rot and accept the autumn rain. Use a shallow rake to reduce evaporation after rain. Another kind, such as sweet potato and cotton, has a short harvest period. If conventional methods are adopted, the sowing date will be delayed, which is one of the important reasons for the low yield of this crop in southwest China. Therefore, on the one hand, it is suggested to loosen the soil between rows in the late stage of the previous crop, and then plow and level it when planting wheat; On the other hand, continuous operations such as potato digging, dressing, fertilization and sowing are advocated to ensure the timely sowing of this crop.

High yield technology

1, pay attention to the high-fat water plot. The high yield and high quality of this crop variety require that the soil nutrients must be comprehensive and sufficient to meet the needs of its high-yield cultivation. Therefore, it is advisable to choose plots with high soil fertility and good irrigation conditions, increase the application amount of organic fertilizer and adopt formula fertilization technology.

2. Pay attention to sowing late in time 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.

3, pay attention to prevent lodging, topdressing at jointing stage. Some high-quality varieties of this crop 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.

4. 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.

5, pay attention to the prevention and control of pests and diseases. Generally speaking, high-quality crops are more prone to diseases and pests, such as 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 this crop treasure once when it reaches 60% ~ 70% before heading and flowering can activate the biological enzyme activity in this crop, promote coordinated growth, enhance the photosynthesis of functional leaves, obviously reduce the empty rate, improve the seed setting rate and 1000-grain weight, thus achieving the effect of increasing production.
