1. Controlling the madness: The cotton stalks are long and mad, which not only affects the normal development of cotton buds, but also reduces the quality of cotton. It promptly sprays the flower wangwang No. 3, forcing the topping essence to reflux, inhibiting the main shoots from becoming mad, without artificial topping. Bud, hormone killing, promote flower bud differentiation, increase the sitting rate.
2. Replenishing the base fertilizer: Phosphorus, potassium, organic fertilizer and other base fertilizers cannot be applied before planting, and should be applied early in the seedling stage. Real-time use of root and micro-fertilizer combined with root irrigation, combined with "micro-fertilizer" irrigation roots, can induce the absorption, digestion and release of nitrogen, phosphorus, potassium and various trace elements in the soil, improve the positive energy of cotton development, optimize quality .
3, pay attention to the weather: mature cotton wool after the rain, cotton fiber will be contaminated, so that the white cotton fiber appears unsightly spots, and even cause mildew and deterioration. Therefore, pay attention to the weather forecast and grab the cotton before the rain. Spraying a new high-fat film 600 times liquid can effectively prevent disease and prevent pollution.
4. Physical regulation: In the late stage of cotton boll opening, spray the tree general + cotton Zhuangting, spray on the leaf surface of the cotton plant and the middle and upper green bells, strengthen the nutrient transport of the cotton peach, increase the expansion vitality, and accelerate the cotton tree. Recycling buds, circulating bobbins, improving fiber quality, while preventing external diseases, insects against cotton, improving resistance and reducing unnecessary losses.
5, prevention and control of pests and diseases: cotton pests and diseases have red rot, verticillium, pink powder disease, anthracnose, blight, aspergillosis, angular spot disease, black spot disease and other diseases, spraying targeted drugs to strengthen management. At each stage of the plant, strict attention should be paid to the movement of pests and diseases. Effective drug control should be carried out according to the disease situation in each growing period. At the same time, a new high-fat membrane should be sprayed to improve the efficacy, so that the pathogens without the diseased parts can not be settled.
