What if the cotton was blown to death by Rain Water?

After timely elimination of waterlogging and clearing of silt ditch cotton fields, the physical and chemical properties of the soil will change. Excessive humidity and lack of air will cause suffocation in the cotton fields. Even if they do not die, they are also susceptible to disease and are not conducive to root binding. Waterlogging must be eliminated as soon as possible. At the same time, the silted ditches, waist ditches and chamber ditches must be cleaned to reduce the groundwater level and create a good ecological environment for cotton seedlings to restore growth.

Help the seedlings to wash the seedlings in time, and wash the seedlings while returning water. Clean the silt on the cotton leaves and stems so that the cotton leaves can restore ventilation and photosynthesis as soon as possible. If the water is too fast, when there is no water to wash, you can use a sprayer to wash. For the crooked cotton plants after flooding, it is necessary to carefully straighten the cotton plants and cultivate the soil to make the plants grow upright so as to improve the ventilation and light transmission conditions of the cotton fields. Serious defoliation of light-stalk cotton field, should be actively rescued, as long as the basal stem scraped off the epidermis can still see the green stem top did not die, we should try our best to rescue, do not easily destroy cotton replanting.

Ploughing and loosening the soil in time. Timely ploughing and loosening soil after the disaster is beneficial to improve soil permeability and promote root development. when the weather turns fine, it is necessary to loosen the soil and break the plate in time, eradicate the sprouting grass buds, cultivate the soil appropriately according to the growth of cotton seedlings, increase the soil moisture in the rhizosphere and promote the healthy growth of cotton seedlings. prevent lodging.

It is suitable for fertilizer and water. The growth period of the damp cotton field has been obviously postponed, so foliar fertilization should be implemented as soon as possible to promote the cotton to recover its vitality as soon as possible. The mixture of 0.2% potassium dihydrogen phosphate and 2% urea can be sprayed with 50 kilograms per mu, and sprayed again 5-7 days after the first foliar fertilizer spraying. There is a large loss of potassium in waterlogged cotton fields, so potassium fertilizer should be applied, 7.5kg / mu of potassium chloride or 150kg / mu of plant ash. Accelerate the healthy growth of cotton.
