Transplanting time and method of cotton

Cotton is mostly planted with seedling transplanting technology, which can promote strong seedlings and lay a solid foundation for high yield. it is one of the more popularized cotton planting techniques at present. So how to transplant cotton? What should I pay attention to? Let's get to know it with the editor.

1. Transplanting time

The temperature and humidity of cotton seedlings during transplanting are important factors affecting the rooting and shortening the slow seedling stage after transplanting. Generally, when transplanting cotton seedlings, the air temperature is required to be above 15 degrees, and the low temperature in 10 cm soil layer is stable above 17 degrees. Root humidity should not be less than 65%. If the temperature is lower than 15 degrees continuously during transplanting, accompanied by overcast and rainy weather, and no new lateral roots have been grown for more than 5 days, then the seedlings will defoliate, the stems will turn red, and it will be difficult to slow down the seedlings. Therefore, the temperature of cotton transplanting must meet the requirements, and a few days of good weather after transplanting will help the seedlings to take root and return to normal growth.

2. Pay attention to the seedling age

Generally speaking, the smaller the cotton seedling age, the shorter the slow seedling stage, but if the seedling age is too small, the slow growth and development of seedlings can not achieve the purpose of fully prolonging the growth period of cotton. However, if the seedling age is too old, there are more true leaves and more roots, it is very easy to hurt the roots in transplanting, which makes it difficult to slow down the seedlings. Therefore, it is generally appropriate for seedlings to grow 3-4 true leaves, and the seedling age is about 40-50 days, when the seedlings have strong stress resistance, easy to survive, strong rooting ability and short slow seedling stage. For seedling transplanting in saline-alkali soil, in order to improve the salt resistance of seedlings, nutrition bowl can be used to grow seedlings to 5-6 true leaves, and then transplant when the seedling age is about 50 days.

3. Transplanting method

In the process of transplanting, we should pay attention to handle gently, try not to hurt the root or less, trench transplanting, to do with the ditch with transplanting, in order to avoid running moisture, ditch to be the same depth, after planting so that the seedling is about 2 cm below the ground. Cover the soil with 2/3, then water it, and then cover the soil after the water is completely seeped. pay attention to the root system not to be exposed on the ground, but also to combine closely with the soil. It can also be covered with plastic film during seedling transplanting to promote the early development of seedlings and to cover plastic film in the field before and after transplanting. This has the obvious effect of increasing temperature and preserving soil moisture, which can greatly shorten the slow seedling stage and promote the cotton to grow quickly and develop early.
