As the autumn season is approaching, in order to improve the quality and yield of wheat, farmers in all wheat regions are actively exploring ways and means of autumn wheat sowing. Mass production practice proves that
In order to increase wheat production, it is crucial to select good varieties.
According to the production level selected varieties
When using wheat varieties, it must pay attention to its high yield and adaptability, taking into account local production levels and production conditions. High-yielding fields with good fertility and water conditions should focus on the use of large-spike wheat varieties that are resistant to fertilizer, lodging resistance, disease resistance, and large yield potential, such as Zhongmai 1, Wenmai 19, etc.; Multi-spike wheat varieties with strong adaptability, stable yield and high yield, such as Bainong 64, Wenmai 6, Xinmai 18, etc.; drought-absorbing and low-yield fields should focus on the selection of wheat varieties with strong adaptability, drought tolerance and barren tolerance, such as short Anti-58 and so on.
According to different farming systems
Different farming systems have different requirements for wheat varieties. For example, in mid-aquaculture areas, middle-early-maturing varieties should be used. In particular, the use of wheat and cotton intercropping, interplanting wheat and peanuts, not only requires the early maturing of wheat varieties, shortening their symbiotic period, but also requires shorter plants, compact plant type, can make full use of light energy and improve photosynthetic efficiency. In addition, different cornices also have different requirements for wheat varieties. In general, winter and semi-winter wheat varieties with strong cold-resistance should be selected for early indica, and spring and spring wheat varieties with fast-growing should be selected for late indica.
According to the local natural ecological conditions selected varieties
During the wheat growing season, natural disasters such as cold, drought, locust, pests, and dry hot winds are encountered. Therefore, in the selection of wheat varieties, attention should be paid to analyzing the characteristics of local natural disasters, and selecting the corresponding resistant varieties according to their characteristics. For areas that are sown early and are vulnerable to cold, semi-winter wheat varieties with strong cold-resistance should be used; in areas where irrigation is inconvenient and susceptible to drought, wheat varieties with high drought tolerance should be selected; pest-prone areas should be selected Wheat varieties with strong pest resistance.
According to market demand, select good varieties
When choosing wheat varieties, it is also necessary to pay attention to the market demand and rationally select improved varieties according to market demand. If the wheat with high quality and strong gluten is popular in the market, when it is selected, it is necessary to select high-quality, strong-gluten wheat improved varieties according to local conditions.
Selection of species must be tested and demonstrated
Each wheat variety has its own variety characteristics and suitable range of cultivation. If it is blindly introduced in a large area, it will often cause unnecessary economic losses because it is not suitable for the local natural ecology and production conditions. For this reason, in terms of production, it is necessary to continuously update the varieties in accordance with changes in the production conditions, and also to prevent the introduction of large-scale tests without tests, and to change them year after year. Generally, a newly-selected or introduced wheat variety should be tested and demonstrated in many local areas. After 2 to 3 years, it is determined that the yield can be increased in a large area compared with the control variety.
