The ability to broadcast whole seedlings after sowing is the basis for seizing the high yield of cotton. In response, the reporter interviewed Xu Fengzhi, an expert in the Xin Qiu Cotton Research Institute of Xin Qiu Seed Industry.
Xu Fengzhi told reporters that after the emergence of cotton seedlings should be promptly checked seedlings, seedlings should be found as soon as possible to make up the seedlings, fill seedlings method is mainly based on the seedling age of the field cotton seedlings decided that the general emergence of real leaf before transplanting buds, emergence of real leaves after carrying soil with plant.
After the seedlings are established, the seedlings will be planted in a timely manner. The seedlings will usually be planted on the cotton fields. After the seedlings are established, the seedlings will be immediately planted, leaving the strong and weak, leaving large and small, leaving 2 or 3 plants per hole, and the cotton seedlings will grow 1 true leaf once. Dingmiao.
For cotton fields that were first sown with a cover film, they should be planted correctly after emergence. The principle of releasing seedlings is to let the greens not be yellow, and the best time to choose the windless sunny afternoon.
Seedlings also need to be cultivated as early as possible, especially in spring and rainy years. The number of times of cultivating in the seedling stage is not as good as possible. It is necessary to pay attention to the timeliness and to let the soil around the cotton plants live. For open-air light-saline alkali fields, attention should be paid to inter-row cultivators, and the number of cultivators should be appropriately increased. When the disease is serious at the seedling stage, the roots must be soiled.
The cotton field with enough base fertilizer may not use seedling fertilizer; if the base fertilizer is insufficiently applied or the fertilizer and water are poor in the cotton field, the seedling fertilizer may be lightly applied as early as possible, and about 5 kg of nitrogen fertilizer may be applied per mu, or the fertilizer may be mixed with organic fertilizer such as cake fertilizer and manure. There is not much water needed in the seedling stage of cotton. In order to prevent the ground temperature from declining, the cotton fields that are planted before planting are generally not suitable for watering. When the individual cotton fields with poor soil moisture at the end of the seedling period continue to be dry, the shallow water should be opened in time and attention must be paid. Pouring after cultivating in time. The mulch covers the cotton field, and on the basis of applying the base fertilizer and making the bottom hoe, no dressing and watering are performed at the seedling stage.
