At present, it is the spring season of "three bamboo branches of bamboo blossoms, the prophet of spring river plumbing ducks", and it is about to enter the sowing period of cotton. It is suitable for us to start preparing for cotton planting. So how does scientific planting lay the foundation for high yield? What should be paid attention to when planting cotton? Seeding should pay attention to these points 1 sowing time: the choice of cotton sowing time, the focus is to see the temperature. Because cotton is warm and light, so the choice of sowing date, Xiaobian's suggestion is that when the film 5cm temperature is stable for 3 days, it is better to sown around 12-15°. Generally speaking, from early April to mid-April, it is the prime time for sowing. But if the soil is suitable for seed germination and the humidity of the crop is enough, then we don't have to wait until this time to choose the seed. If the sowing is too early, the temperature at the time of sowing is not enough, it is easy to cause rotten seeds, rotten buds, weak seedlings, easy to infect disease and dead seedlings, resulting in uneven emergence and so on. If the planting is too late, although it can guarantee the emergence of seedlings, but can not cultivate early seedlings and strong seedlings, it will delay the growth period of cotton, miss the best growing season, affect the growth progress of cotton, and finally directly affect the yield and quality of cotton. 2 sowing depth: the sowing of cotton should also pay attention to the depth of sowing. Too deep, the soil layer is too thick, the germ can not penetrate; too shallow, the soil layer is too thin, the seeds are exposed and can not absorb enough water to germinate. Therefore, sowing our general depth of about 2.5 cm is the best, depending on the humidity, in general, a guarantee: a maximum of 3.5cm, the shallowest can not reveal the seeds. After sowing, it is necessary to crush the soil in time. 3 seeding density: seeding amount, pay attention to a reasonable close planting. According to the seed germination rate, soil quality, density, climate, the number of plants per acre is reasonably arranged. In particular, sandy land has poor fertility and proper close planting; while clay land has good fertility, it is appropriately planted. The planting density is based on the ability to ensure good photosynthesis, avoiding poor ventilation and light transmission in cotton fields, and reducing photosynthesis. In this way, not only is it not conducive to cotton development, unfavorable and agricultural operations, it is also easy to cause pests and diseases and reduce cotton quality. Before planting, the variety is selected, this money can not be saved. Then carry on the sun. Sun-breeding can promote the seed after the tree, improve its disease resistance and promote germination. Selection should refer to clarity, purity, seed germination rate, germination rate, and water content. 4 soil improvement: It should be noted that cotton planting should avoid saline soil and soil compaction. These areas will lead to a low emergence rate of cotton fields, affecting cotton growth and later. Therefore, this kind of land must first improve the soil acidity and alkalinity, the specific method is to increase the application of decomposed farmyard manure and organic fertilizer. Sandy soil can be sprinkled with weathered coal to prevent the loss of water and nutrients. The precautions about cotton planting are mentioned here, and the above points can be used to lay the foundation for the scientific cultivation of high-yield cotton. Therefore, it must be carefully managed during the sowing period of cotton.
