Top-dressing with watering: To properly water, and apply a small amount of nitrogen fertilizer to promote seedlings. For the poor fertility, insufficient or less base fertilizer, weak cotton growing field, combined with water can be recovered 5 acres of urea. Phosphate fertilizer and potash fertilizer can also be added at the same time. Usually, 5 kg of diammonium, potassium sulfate or potassium chloride are applied in each mu.
Take the initiative to control Wang: spray the water before the promotion of Kao No. 3 cotton topping agent active control. The promotion of Kaowang No. 3 cotton topping agent will dissolve 1 kg of water per bottle into mother liquor, and then add 500 kg of water and stir and dissolve. At the beginning of the flowering period, peaches were sprayed on the top of the cotton and sprayed three times in a row for 7-10 days.
The cultivating soil: cultivating soil, especially deep cultivating soil, plays an important role in the control of the cotton plants, the promotion of cotton roots, and the stability of strong trees. However, classification should be carried out. After the general rainfall or irrigation, and when the cotton plants grow well, they should be deeply cultivated. For dryland cotton fields, it is mainly shallow-grassed grass and no deep-middle-cultivation is required. We should master the principle of maintaining soil looseness in the fields and not weeds, and at the same time, combine cultivators to do a good job of earth-cultivation.
Scientific pruning: For the pruning of cotton fields, timely removal of leaf shoots and axillary buds should be done so that the axillary buds do not overshoot but the leaf shoots are not too close to one another. It should be earlier than late to reduce nutrient consumption and effectively regulate the distribution of nutrients from the cotton plants to the fruit branches to improve field light control. The cotton plant grows mad.
Disease prevention and pest management: According to the local pest monitoring, we must pay close attention to the timely prevention and control of pests such as cotton aphid, cotton leafhopper, whitefly, cotton aphid, and blind aphid.
