Four questions after cotton post-production management
What if the cotton is not enough after sowing?
After sowing cotton, it is necessary to check the soil moisture in time. For cotton fields with poor moisture and possible drying, small water can be ditched in the seed ditch; cotton fields without water pouring conditions can be used to suppress the seedlings before the seedlings are unearthed.
What should I do if the cotton is rained after sowing?
After the cotton is planted, it is rainy, and the floor is easy to form a shell. After the rain, the soil should be drained in time to remove the knot and help the seedlings to be unearthed. If the overburden is too thick, the soil should be rescued by the soil; the seedlings that are picked up cannot withstand the glare of the sun, and the seedlings should be kept in a small amount of wet soil in the upper part of the seedlings.
What should I do if the cotton is not taken after sowing?
After the cotton is planted, it is necessary to check the emergence of the seedlings in time. Once the phenomenon of missing or rotten seeds and rotten buds is found, it is necessary to carry out germination and replanting as early as possible; if the missing plants are broken, the seedlings should be transplanted immediately. Before the emergence of a real leaf of cotton seedlings, the seedlings were transplanted; after the emergence of true leaves, the soil was transplanted. Regardless of the type of transplanting method, watering should be minimized to shorten the slowing time. In order to prevent the seedlings from being bullied, the transplanted cotton seedlings should occupy a large space.
What should I do if I encounter low temperature weather after sowing?
During the sowing and emergence of cotton, the weather is often changeable. Once cold weather is encountered, it is necessary to timely increase the temperature, or apply grass ash along the ridge to increase the soil temperature around the cotton seedlings. If necessary, spray cotton seedlings with 25% carbendazim 500-800 times solution or 70% methyl phenyl thiophanate 1000 times solution to prevent the spread of the disease.
