1. Clean the ditch and drain to prevent the cotton field from being stained. Dredge and deepen the furrows around the cotton field, and ditch the furrows. If the field is long, pay attention to opening the middle furrow.
2. Seize the fine weather, suitable for soil cultivation and soil cultivation. When the rain stops and turns into fine weather, after the cotton fields are basically harvested, cultivating and loosening the soil in time to promote aeration to improve the drought resistance and lodging resistance of the cotton plants.
3. Remove leaves and branches to reduce nutrient consumption. After cotton has 1~2 fruiting branches in the bud stage, combined with field cultivation and soil cultivation, timely removal of leaf branches can not only reduce field canopy, but also reduce nutrient consumption, improve the ventilation and light conditions of cotton fields, control nutrient growth, and reduce young bud shedding .
4. Do a good job of chemical control to prevent excessive growth. Rain is beneficial to the acceleration of cotton plant growth and the imbalance between vegetative growth and reproductive growth. After the rain stops and turns to clear, in addition to deep field cultivation to control the growth, you can prevent the growth of the cotton plant by spraying the supplement. The dosage is 2 to 5 ml per mu, and 30 kg of water is sprayed on the young part of the cotton plant.

By setting a protective collar, the neck of the operator can be kept warm and protected. The provision of a hand guard is helpful for the surgical staff to temporarily place their hands in the hand guard while waiting during the operation, which plays a protective role and is more in line with the principles of aseptic operation and occupational protection.
By setting the shrinking cuffs, it is beneficial to make the cuffs fit the wrists, prevent the cuffs from loosening, and prevent the gloves from slipping off during the operation and the operator's hands are exposed to the gloves.
The design of the new humanized protective surgical gown has been improved in the key areas of the gown. The forearm and chest area are double-thickened, and there are handguards in front of the chest and abdomen. By arranging reinforcing sheets (double-layer structure) in key areas, it is beneficial to improve the water-permeability of surgical gowns and improve safety.
