To grow good cotton, we must master the key technology, what are the key technologies?

The key technology is to grasp the planting method of cotton, grasp the disease prevention and control of cotton, but also pay attention to the fertilization of cotton, but also pay attention to the growth process of cotton, and the sowing method of cotton.

First of all, it is necessary to focus on basal fertilizer, supplemented by fertilization, and to apply organic fertilizer, to regularly and appropriately water, to carry out water level control.

The key technology is to master the temperature difference, maintain it at 10, and add chemical fertilizers in time, so that cotton will grow bigger.

To plant good cotton to master the key technology, first of all, before planting must choose a good variety of good varieties, in the planting of bad cotton will be much less, there is to eliminate pests frequently, do not let pests affect the growth of cotton, need to always pay attention to the growth process and environment of cotton, timely treatment.

First of all, we must master very good sowing techniques, and we should also choose seeds, and we should also water and fertilize them in time, and we also need to choose some good fertility, and we should also ensure that the pH of the soil is appropriate.

First of all, the seeds should be spread and dried before sowing, which is conducive to improving the germination rate of cotton seeds; The second is to choose the right time to sow seeds, cotton likes temperature, and it must be sown when the temperature begins to stabilize; In addition, it is necessary to sow the film first for the sandy land and cover the film, and cover the film before sowing the clay soil for the clay soil.

The key technology is to buy particularly good varieties of cotton, and also to fertilize the cotton scientifically, but also to choose the right time for sowing, at the right time to top dressing and watering, but also to protect the cotton from diseases and insects, so that the cotton can grow very well.

First of all, we must choose the right soil, but also choose full seeds, and cotton is a plant that likes fertilizer very much, so the fertilization must keep up, generally eat 1 2 times a week, and the planting time must also be selected, generally in the autumn of each year.

Suitable temperature, suitable site, comfortable geographical location, as well as the selection of high-quality varieties, do a good job in the prevention and control of diseases, insects and weeds.

The key technologies are these: 1. Choose a good variety. Fewer pests, fewer male forks, 2

Control the sowing time. Spring sowing or summer sowing is worth cultivating, and there is a difference between the north and the south. 3.

Recognize the male and female branches. 4.Get out of the way at the right time and cover your heart.

5. Manage different pests and diseases at different times.

Cotton is one of the cash crops, farmers in some areas of our country are relying on planting cotton to bring economic benefits, so what aspects of cotton planting technology need to be paid attention to? Let's do a simple study. Key points of cotton planting technology and management.

Generally speaking, the life of cotton from planting to harvest can be roughly divided into the following five stages, sowing seedling stage, seedling stage, stage, flowering stage and bell stage, each stage pays attention to five stages, any stage of maintenance does not reach the specified position, will directly affect the harvest and yield of cotton.

<> let's take a brief look at the duration of each phase. Seedling stage Generally speaking, the seedling period is from the end of April to the beginning of May, and the general emergence of seedlings takes 7 to 15 days, because in the seedling stage, the insect resistance of seeds is relatively weak, so the insect resistance of the seedling stage is particularly important, followed by the seedling stage, this stage is from the emergence of seedlings to the emergence of buds This period, generally 40 to 50 days, at this time we mainly ensure its healthy growth, and then it is the budding time.

Many cotton planting areas often have a low germination rate and uneven seedlings, which is largely due to the residual waste film, cotton wood, weeds, stems, root rot, etc., which are easy to cause cotton seeds to be not tightly combined with the soil in the soil, and the seeds are affected by problems such as root system, roots, and coating air leakage. Therefore, the field debris must be thoroughly cleaned before planting before spraying and weeding. Cotton seeds need sufficient water from sowing into the soil to emergence** (about 60% of the weight of the seeds are needed at the germination stage, and about 15% water is needed at the seedling stage).

For planting areas with less water in spring drought or winter and spring, it should be watered before sowing to protect moisture, otherwise it will affect seed germination and seedling growth.

Do a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me more, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you.

First of all, we must choose excellent varieties, when sowing, we must dry the seeds in advance for about 4 5 days, and then this can promote the germination rate, when laying the mulch film should be chosen at the end of April, if it is sandy soil, we must first sow the mulch film, if it is clay soil, we must cover the film first and then sow it. Because this planting technology can increase cotton yields, it can increase profits for farmers.

When planting cotton, we must choose the soil is relatively fertile and broad, and we must use farmhouse fertilizer when fertilizing, never use the fertilizer bought outside, and often water the plants, but also to prevent the occurrence of pests and diseases, if there are small insects, then we must spray insecticides in time. Because only by doing this can cotton be planted well, and cotton production can also be increased.

It is necessary to master the technology of artificial planting, and at the same time, it is necessary to master the technology of reasonable planting density. Choose the right method of wetland-based fertilizer. It is also necessary to pay attention to the reasonable control of pests and diseases, because only by mastering these techniques can cotton be planted reasonably.

Cotton scientific planting technology includes the following aspects:1Soil Improvement:

Select the right land and suitable soil, and increase ridge air fertilization, soil turning and deep turning technology to maintain soil fertility and moisture. 2.Seed selection:

Select high-quality cotton seeds, and pay attention to controlling factors such as temperature, humidity and light during the seedling period to ensure the healthy growth of seedlings. 3.Reasonable dense planting:

Grasping the appropriate planting density prevents the growth of weeds and competition for cotton among cotton, and also ensures sufficient sunlight and air circulation, which is conducive to cotton growth. 4.Proper fertilization:

According to the soil fertility and the needs of the cotton growth period, strengthen fertilization, try to replace a single chemical fertilizer with organic fertilizer and compound fertilizer, and reasonably fertilize and supplement nutrients. 5.Pest Control:

Regularly inspect and monitor the situation of wild pests and diseases, and take scientific control measures in a timely manner, such as reasonable sprinkler irrigation, biological control of late blind pests and diseases, etc., to ensure the health and efficiency of cotton production. 6.Scientific Management:

Regular field management of the cotton area, including weed removal, timely pruning of branches and leaves, and regular monitoring of the growth and fruiting of cotton so that possible problems can be dealt with in a timely manner. In short, scientific cotton planting technology can improve the yield and quality of cotton, and ensure the health and stability of cotton growth.

Be sure to choose those *** cotton seeds first. The soil should also not be too moist. It is necessary to improve the structure of the soil.

Avoid the formation of a lot of germs in the soil. It is necessary to choose a suitable soil for sowing, so that the quality of cotton production will be greatly improved.

First of all, it is necessary to choose cotton varieties of very good quality, and in the selection of soil, it is necessary to choose soil with moderate moisture content for sowing, and then pay attention to the control of pests and diseases in the process of growth. Mastering these technologies can effectively improve the quality and yield of cotton, and can also make some farmers have good benefits.

Because the seed fly larvae in the soil of cotton field are similar to the pathogenic bacteria of cotton seedling blight, anthracnose and red rot, it is easy to cause seed and bud rot, thereby affecting the emergence rate of cotton seeds, therefore, it is an important way and measure to control pests and diseases and improve the emergence rate of cotton seeds. Uncoated cotton seeds should be chemically treated. Seed dressing that accounts for seed volume can be used for seed dressing, with 2 3 kg of water per 100 kg of seeds.

Choosing good weather before sowing and spreading cotton seeds in broken bags for 2 3 days can effectively promote the post-ripening of cotton seeds, kill the pathogens carried by the seeds, and improve the emergence rate of cotton seeds. The rotation of cotton field and gramineous crops in rotation can improve soil structure, reduce the occurrence of cotton seedling diseases, and increase the emergence rate. Therefore, when choosing land to grow cotton, it is better to choose land that is not planted with cotton or land that rotates crops, and avoid planting cotton on land that has been planted for many years.

Appropriate sowing is an important part of preserving and nurturing strong seedlings. Semi-precision and precision sowing should be used for delinquent coated cotton seeds as much as possible, and the principles of suitable moisture sowing, appropriate late sowing, appropriate depth sowing, and appropriate increase of sowing amount should be followed; Late sowing at the appropriate time is to shorten the seedling emergence time and reduce the rotten seed and germination rate, which is generally sown from April 16 to 26; Appropriate depth sowing is to strive for the sowing depth to control in centimeters; Appropriately increasing the sowing amount is to double the sowing amount per mu than usual.
