This year, despite the postponement of the start of the cotton sowing period, the sowing period was extended due to the suspension of the cold and windy days before and after the Ching Ming period. In addition, due to the continuous floating weather of several days, some cotton fields had the phenomenon of mild rotten and rotten shoots. Slightly slow, there are three true leaves for the early sowing cotton and one true leaf for the sowing late cotton field. However, all cotton-growing counties (cities) attach great importance to cotton sowing, strictly control the four junctures, and pay close attention to the implementation of the technical measures for cotton sowing. First, they must pay attention to the quality of soil preparation and strive to achieve “powder, flat, loose, broken, net. , Qi, and straight; the second is to grasp the cotton seed, use the coating or chemical seed dressing cotton seed; third is to grasp the actual seeding quality, suitable for seeding, so that the film spread flat, compact membrane, uniform casing The fourth is to grasp the actual broadcast after the Tian Guan Guan, lax or misplaced timely blocking the membrane hole to prevent loss, the lack of seedlings off the ridge in time to make up the seedlings. Due to the implementation of technical measures, the emergence rate of cotton was significantly higher than that of the previous year, and cotton production showed a good start. The emergence rate of most cotton fields currently exceeded 85%.

In the next step, we must focus on cotton pest control work. First, we should do a good job of prevention and control of cotton thrips. It is expected that cotton cocks and horses will enter the peak of damage from May 10 to 15 and before and after, it is recommended to use omethoate, acetamiprid or Imidacloprid and other systemic high-efficiency and low-toxicity pesticides are used for spray prevention and prevention of multi-headed cotton or headless cotton caused by the damage of cotton thrips. The second is to do a good grasp of cotton aphid prevention and control, the current cotton aphid in the cotton field has sporadically, it is expected that the emergence of the center of the plant, the spotting period is in late May - early June, it is recommended before the large number of cotton aphids into the cotton field, put the yellow plate Trapping and killing winged crickets; 40% omethoate or Confodo can be applied to stems when found in the center; for cotton fields with more maggots and larger number of natural enemies, wash urine mixture or 0.5% matrine water spray is recommended. Treatment, to maximize the protection of natural enemies, gain control of the harm; for more than a few spots, the number of natural enemies in the cotton field, available imidacloprid, acetamiprid, Mobilang and other agents pick governance.
