First, choose varieties based on planting cornices. Teng Hao early, early gargle, early planting, must use winter, semi-winter varieties. In the evening, in the middle and late evenings, spring and spring varieties must be selected.
Second, choose varieties based on ecological types. Hilly land and dry thin land: It is necessary to select multiple panicle varieties with strong tillering ability, high spike success rate, and more spikes, because these varieties have the ability to resist drought and barrenness at the same time. Plain areas: high-fertility plots, we must choose high-resistance, disease-resistant varieties, such as warm wheat series. In the medium-fertility plots, it is necessary to select stable and high-yielding varieties with outstanding yield and wide adaptability.
Third, we must scientifically select varieties based on the level of fertility, the level of fertilization, and the characteristics of varieties.
Fourth, for the cultivation of high-quality special wheat (strong gluten), we must pay attention to the signing of contracts with external parties, the development of agricultural orders, and the simultaneous expansion of large-scale planting in order to achieve higher prices for better quality.
Fifth, according to the seeding schedule. When choosing wheat varieties, farmers' friends must carefully read the variety introduction, consult relevant experts and agricultural science and technology personnel, and distinguish the species of the purchased varieties, ie, whether the purchased varieties are winter or semi-winter varieties or whether they are spring Sexual, weak spring varieties. If it is winter or semi-winter, it can be sowed early; if it is spring and weak, it should be sown late. What needs to be particularly reminded here is that spring and weak spring varieties should adhere to the principle of swiftness rather than earlyness and must not sow early. In recent years, there have been some frozen crops in the northern part of the wheat fields, most of which are due to the early sowing of spring varieties. In general, the weak spring variety must be sown after October 10, and the spring variety must be sown after October 12.
Sixth, to see whether a variety is good or bad should be determined by years of continuous performance. Such as Xinmai 9, Wenmai 6, Wenmai 4, Qimai 4, Neixiang 188, etc., have been proved by continuous performance in recent years is wide adaptability, strong resistance, outstanding comprehensive performance The varieties, although not the latest ones, can be boldly promoted and utilized. Another example is Zheng Mai 9023, which is a comprehensive high-quality wheat variety with outstanding performance. This year, large-scale frost damage occurred and production was reduced. This is not because this species is not good, but because it is a spring variety with fast development, early jointing, and jointing. After the fall of cold resistance, intolerance of low temperature, can not be early sowing, in recent years, the incidence of frost damage and production is due to early sowing. Therefore, Cheng Mai 9023 still has value in use and can still be widely used for planting, so long as it pays attention to sowing on October 12 after the Gregorian calendar.
