< p > when selecting cotton varieties, we must choose the cotton varieties with high purity and no pests and diseases. We should choose the peach in the center of the land and choose the dried flowers.

In addition, we should pay attention to the following points: < /p >

< p > do not choose hybrid cotton varieties. Under the current level of science and technology, the F2 segregation of hybrid cotton varieties is very serious.

< /p >

< p > do not choose the peach and late autumn peach before the peach and late autumn Peach Growth and development are bad, maturity is bad, bell weight is light, seed germination rate is low, growth is weak, should avoid seed.

< /p >

< p > do not choose "peeled peach" cottonseed. Some cotton growers still have the bad habit of "peeling peach blossom and picking wet flowers" for the more developed peach, because such a peach is not fully matured, and has not finished ripening.

< /p >

< p > do not choose seriously degraded cotton varieties.

Cotton is a cross pollinated crop, and the outcrossing rate is 3% to 20%. If the insect resistant cotton varieties are not purified and rejuvenated after several years of continuous propagation, they will often cause biological confusion due to insect pollination.

Therefore, it is necessary to avoid seed reservation for plots with low purity and serious deterioration.

< /p >

< p > do not select cotton plants with serious diseases and insect pests.

Fusarium Wilt and Verticillium wilt are stubborn diseases that restrict cotton yield. Cotton seeds are carriers of pathogens, and germs can spread quickly with cotton seeds.

Therefore, the cotton plants infected with Fusarium Wilt and Verticillium wilt should be eliminated.

Cotton plants with good performance in severe diseases can be planted.

< /p >

< p > do not choose the cotton seeds that have been dried on the cement floor to dry the cotton seeds with high moisture content on the cement floor, which will cause some cottonseed to form "dumb" and lose the germination ability.

< /p >

< p > do not choose cottonseeds stored together with pesticides and fertilizers.

Some farmers have stored cottonseeds and pesticides and fertilizers for a long time. Due to poor ventilation, poisonous gases emitted from pesticides and fertilizers can damage cottonseed, resulting in a sharp reduction in germination percentage of cottonseed.

< p > cotton prices are good, cotton growers' enthusiasm for cotton growing is high, and cotton seed market is in turmoil.

In addition, last year cotton mature period, but for a long period of rain and light, cotton maturity is not good, most cotton seeds germination rate is only 30% to 40%, some only about 10%.

< /p >

< p > cotton farmers choose seeds when they choose the seeds. Two increase the seeding rate and three prepare seedlings.

Xinjiang cotton area dry climate, where the cotton seed production, maturity and plumpness is certainly no problem, but there are light pests, large areas do not broadcast insect resistant cotton, purchase of cotton seeds pferred from Xinjiang should also be carefully selected; only from the regular good (original) seed farms and good breeding base on the seeds to ensure the purity of varieties.

< /p >

< p > by the latest scientific research results introduced by the Shanxi Yuncheng Association of agricultural experts from the China Cotton Research Institute, the "Cotton Cultivar 45", which is bred directly in Xinjiang's national crop seed farm, can guarantee the quality of varieties and seeds. Compared with the "cotton 41", the variety has strong boll setting ability, high yield, strong resistance to disease and insect resistance.

< /p >

< p > cotton growers purchase < a href= "http://www.91se91.com" > cotton seed < /a >, first, we need to know the origin of the production. Two, we must see that the business procedures are complete, and three, we need to obtain purchase evidence to facilitate inquiries.

< /p >

< p > improve cotton seedling, seedling and strong method: for the past years, when planting cotton, there are more cold damage weather. Agricultural experts suggest that when cotton farmers sow their hair, they should choose sunny weather 2 times, 3 times before planting.

One day before planting, use three seeds and one cold seed soaking (with the seed stirring with stirring) for half an hour, then add cold water for 8 hours, then fish out and mix with "Wan Chun ti" nutrient solution (1 mu seed with a spring of spring) and then mix with sand and lime.
