How to plant cotton

Cotton is one of the most important crops in the world, and it is a crop with a long history introduced by our country, and it is also widely planted in our country at present. Now cotton is not only used in the weaving industry, but also can be used in the production of beauty products and cut flower materials, the use value has been expanded, which also improves the economic value of cotton. So what the editor is going to teach you today is the method of growing cotton. Let's learn it together.

1. Seed selection and soil preparation

At present, there are many varieties of cotton, such as white cotton, colored cotton, yellow cotton, grey cotton and so on, so the cotton varieties suitable for planting in different areas are different, so we should choose local varieties with high yield and high quality according to the local planting environment. The second is the preparation of the planting land, the water demand and fertilizer demand of cotton are relatively large, so the soil of the planting land should be fertile, good drainage, loose soil and moderate pH. It is necessary to dig the soil deeply, clean up the impurities in the soil, turn the soil again after full base fertilizer, and water the soil before planting to keep the soil moist, which is conducive to the growth of cotton roots.

2. Scientific planting

Cotton planting is generally carried out through seedling planting, that is to say, we have to go through a period of seedling raising period, and then transplant into the field when the seedlings grow to a certain extent. Sow as early as possible when sowing, so as to avoid a lot of diseases and insect pests. When sowing, we all use the way of strip sowing, the distance between each is about 20 centimeters, spread the seeds evenly in the ditch, and finally cover the seeds with soil and cover the seeds with water, preferably with a layer of straw or plastic film on it. this can play the role of heat preservation and moisturizing, but also conducive to the emergence of cotton seeds. However, it should be noted that after the emergence of the seeds, they should be removed in time to avoid burning seedlings.

3. Field management

The field management of cotton is actually more complex, because it has a relatively larger workload compared with the planting management of other crops. In the early stage of cotton planting, we should grasp the whole seedling and prevent diseases and insect pests at the seedling stage, and we should carry out intermediate ploughing and weeding after every watering, rainfall or field work to maintain the permeability of the soil. Until the middle stage of cotton growth, that is, the bud period of cotton, we need to carry out topdressing, watering, ploughing, soil cultivation and other management work. Topdressing is mainly to promote the growth of cotton plants and promote the growth uniformity of flower buds. Not only extra-root fertilization but also foliar fertilizer is needed. Finally, the middle and later stage of cotton growth management, we also call it the boll opening period, this period can be said to be the key period of high yield and high quality of cotton. We need to do a good job in pruning, chemical control, ploughing and weeding, page topdressing, watering, drainage and irrigation.

4. Prevention and control of diseases and pests

In the whole growth process of cotton, in fact, its diseases and insect pests are still relatively frequent. For example, during the seedling period, the most common diseases and insect pests are blight, anthrax, cotton aphids, ground tigers, etc., so we can use allicin, carbendazim, aldicarb, phoxim and other agents for control. In the later stage, the most important thing is to prevent the harm of insect pests to cotton, including blind Toona sinensis, aphids, cotton bollworm and so on. We can use Regent, high-depth imidacloprid, methamidoprid salt and high chlorine to spray before nine o'clock in the morning or after five o'clock in the afternoon.
