When will cotton be planted? Little knowledge of cotton planting

Cotton planting time

Under normal conditions, cotton is suitable to be planted around April to May.

Little knowledge of cotton planting

(1) plot selection: cotton is a temperature-loving and light-loving crop. Liaoning belongs to the extra-precocious cotton area, which is the province with the highest latitude in the cotton area of the country, and it is not suitable to plant cotton in the cold areas of the north. The root system of cotton is well developed, and the root depth is more than 2 meters. Therefore, the cotton field should choose flat land or sunny sloping land with deep soil layer and medium fertility. Sticky soil, back sun, waterlogged cold pulp land is not suitable to grow cotton, the agricultural proverb said: "Cotton seedlings are like fire, sandy land is the best."

(2) ridging: the ability of cottonseed top soil is strong, and two leaves should be unearthed, which has great resistance. Moreover, the yield increase of cotton in Liaoning mainly depends on the monarch, and a certain density must be guaranteed. Sowing and protecting the whole seedling is the basis for increasing cotton production. Therefore, cotton field preparation must be meticulous, cottonseed emergence and water absorption is slow, cottonseed itself is rich in fat and protein, slow material transformation, long seedling emergence time, large water absorption (equivalent to seed weight), cotton field should maintain sufficient water. It is required that cotton field preparation should be ridged as early as possible, the best ridging in autumn, and ridging in spring should also be completed before the end of March, no later than April 5 (before Qingming Festival). The soil preparation is fine and bumpy, the upper part is empty and the bottom is solid, and the soil water content is not less than 18%. Ridging and fertilization should not be less than 3000 kg of agricultural fertilizer.

When will the cotton be planted? Planting time and method of cotton

Cotton is an annual herb of cotton genus of Malvaceae, and it is one of the most important crops in the world. Cotton has the characteristics of high yield and low production cost. it is not only a fiber crop, but also an important oil crop. So, when will the cotton be planted? How should I plant it? Now the planting time and methods of cotton are introduced as follows.

I. planting time of cotton

Due to the different weather and climate in different regions, the cotton planting time is also different, generally speaking, the cotton planting time is about April of each year. In fact, since spring and March, farmers began to buy cottonseed to grow cotton, but since cotton is not planted directly like beans, cotton seedlings are all being cultivated at this time, so the real planting time for cotton should be the end of March and the beginning of April.

II. Planting methods of cotton

1. Preparation before sowing: the purchase of improved cotton varieties is recommended to change seeds every year, do not be cheap, use the second or third generation of cotton seeds, because the output of self-retained seeds is reduced by about 10% every year. Use about 1.5 kilograms of seeds per mu, dry the seeds before sowing, the cumulative drying time is not less than 30 hours, and constantly turn over. Be careful not to spread it directly on the cement floor, brick floor or metal plate. Before sowing, the soil moisture must be made and preserved in time, so that the soil moisture can be planted.

two。 Fertilization and sowing: generally apply 3-4 square of high quality farm manure, 10 kg of urea, 20 kg of diammonium, 20 kg of potassium sulfate compound fertilizer and 2 kg of boron, zinc, manganese, iron and other micro-fertilizers. Sowing prematurely will result in incomplete emergence of seedlings, aggravation of diseases in seedling stage and premature senescence in later stage due to low temperature. Too late is easy to cause overgrowth, sitting peach on the upper side, missing the best boll period, which is not conducive to high yield. The best sowing date is about April 20, and the sowing depth is about 3 centimeters. According to the soil moisture, the soil moisture is slightly shallower than the clay soil, and the soil moisture is slightly deeper than the sandy soil.

3. Reasonable close planting: sand, poor fertility of the appropriate close planting, clayey soil, good fertility of the appropriate sparse planting, the recommended practice is to plant large and small rows of about 1 meter, small rows of 55 centimeters, plant spacing of about 40 centimeters. When planting with tractor plastic film mulching, there are now a considerable number of cotton farmers who leave too many seedlings at seedling stage, early closure of cotton lines, poor ventilation and light transmission, resulting in reduced photosynthesis, serious shedding of buds and bolls, aggravation of cotton diseases and insect pests, and increase of ineffective branches, which is not conducive to field operation. the yield and quality of cotton are reduced, affecting income.

4. Topdressing watering: generally without watering at the seedling stage, 20 kg of urea per mu at the flower and boll stage, and about 15 days of drought at the early flowering stage. At noon, the leaves should be watered in time when they wilt slightly, even if it rains and is not permeable. Finally, after cotton bolls are opened, they should also be watered once in case of drought, which can improve root vitality, delay cotton senescence, increase boll weight, and increase yield by about 10%.

5. Chemical control and topping: the scientific use of Jiaoan and Zhuangzhu is the key measure to build a high-yield shelf to achieve high yield. Chemical control begins at the budding stage, 0.5 grams per mu for 6-8 leaves, 1.5 grams per mu for early flowering, and 3 grams per mu after topping. Master the principle of "light in front and heavy in back, a small number of times". To hit the top, you should master "time to wait for branches, branches to see the growth", the general cotton field will be completed on July 15-20.

6. Pest control: Tian Da 2116 plus carbendazim plus imidacloprid can be used in the seedling stage, and carbendazim is added to sterilize every time. Phoxim, malathion, cypermethrin, avermectin and other pesticides are used alternately to control cotton bollworm, blind Toona sinensis, red spider, etc., and potassium dihydrogen phosphate, urea and micro-fertilizer are added alternately at the same time of spraying.

[conclusion] Cotton is a light-loving crop, which is suitable to grow under sufficient light conditions, and special attention should be paid to the planting process. Above for you to introduce the planting time and methods of cotton, hope to help you!
