Cotton remedy

Timely elimination of waterlogging and cleaning up the silt After the flooding of the cotton field, the physical and chemical properties of the soil will change. Excessive humidity and lack of air will cause the cotton field to suffocate and die. Even if it does not die, it is susceptible to disease. It is not conducive to the root system and must be removed as soon as possible. In addition to removing waterlogging, the silted gutters, gutters, and gutters will be cleaned to reduce the groundwater level and create a good ecological environment for cotton seedlings to restore growth.

Miaomiao wash seedlings in a timely manner, while leaving the water wash seedlings. The sludge on the cotton leaves and stems was cleaned to restore the ventilation and photosynthesis functions of the cotton leaves as soon as possible. If the backwater is too fast and waterless, it can be sprayed with a sprayer. For the cotton plants that have been flooded and swollen after flooding, the cotton plants should be carefully centered and cultivated to stabilize the plants so that the plants can grow upright to improve the ventilation and light transmission conditions of the cotton fields. Serious defoliated light stalked cotton fields should be actively rescued, as long as the base stalk scratched the epidermis still visible to the top of the green stem is not withered, we must do our best to rescue, do not easily destroy cotton to change species.

Timely tillage loose soil. The timely and cultivating loose soil after the disaster is conducive to improving the soil permeability and promoting the development of the root system. When the weather turns fine, it is necessary to loosen the soil in time, eradicate the sprouting grass buds, properly grow the soil as the cotton seedling grows, and increase the soil moisture in the rhizosphere and promote cotton growth. The seedlings grow robustly to prevent lodging.

Apply fertilizer water. The growth period of wet cotton fields is significantly delayed. Foliar fertilization should be implemented as soon as possible to promote the cotton to restore its vitality as soon as possible. 0.2% potassium dihydrogen phosphate and 2% urea mixed liquor 50-75 kg can be applied per acre, and the first foliar fertilizer spray can be applied. Spray it again 5 to 7 days later. The loss of potassium from cotton fields is large and should be supplemented with potash fertilizer, applying 7.5 to 10 kg of potassium chloride per mu, or 150 to 200 kg of plant ash. Accelerate the growth of cotton.

Prevent pests and diseases. After the water receded, the cotton strain should be immediately sprayed with 50% carbendazim 800 times solution or 800 mg solution of copper ammine. To protect leaves, protect buds, protect bells, and grow new leaves, they are susceptible to many pests such as locusts, aphids, and red spiders. They can be sprayed with pesticides such as monocrotophos, cypermethrin, omethoate, and konjac. Shi, to have budding cotton to strengthen the second and third generation of cotton bollworm prevention and control.

Fragmented buds, chemical regulation. Special attention should be paid to the finely pruned cotton after submergence to reduce the consumption of nutrients and ensure the need for multi-plumbing and heavy attack. For a cotton field where fertilizer and water growth is prosperous, it is necessary to conduct a chemical control, which will promote more flowering and more bells, strive to pour over the full moon, and cover the top with autumn peaches to make up for the loss of flooding.
