When selecting cotton varieties, choose high-purity plots and pest-free cotton plants. Select the Piaotao at the center of the site and select the ripe “dried flowersâ€. Also note the following points: Do not select hybrid cotton varieties. Under the current state of the art, the separation of hybrid cotton varieties F2 is very serious and should be avoided. Do not choose before the peach and late autumn peach peach and late autumn peach growth and poor growth, poor maturity, boll weight, seed germination rate is low, growth is weak, should avoid seeding. Don't choose cotton seeds that “peel peachesâ€. Some growers still have poor habits of “splitting the mouth and picking wet flowers†​​because some of them have not fully matured, and they have not completed the post-cooking and must not stay. Species. Do not choose seriously degraded cotton varieties Cotton is a regular cross-pollination crop, out-crossing rate of 3% to 20%, after several years of continuous breeding process, insect-resistant cotton varieties, if not purified, often due to insect pollination Cause biological confusion. Therefore, for the plots with low purity and severe degradation of species, avoid seeding. Do not select cotton plants with severe pests and diseases Wilt disease, Verticillium wilt is a chronic disease that restricts cotton production, cottonseed is also a carrier of pathogens, germs can spread rapidly with cottonseed. Therefore, cotton plants infected with wilt disease, verticillium wilt, and cotton plants with weak insect resistance must be eliminated. However, cotton plants that perform well in serious diseases can be kept. Do not choose cottonseeds that have been sun-dried on cement floors. Applying cottonseeds with high water content on the concrete floor will cause some cottonseed to become “muted†and lose its ability to germinate. Do not choose cottonseeds stored together with pesticides and fertilizers. Some farmers will store cottonseed with pesticides and fertilizers for long periods of time. Due to poor ventilation, toxic gases emitted from pesticides and chemical fertilizers will damage cottonseeds, resulting in a sharp decline in the germination rate of cottonseed.
