1. Seedbed preparation: Each seedbed (each mu) shall be excavated with a width of 1.1-1. 2 meters, a depth of 20 cm, and a length of 2.2 meters.
2. Lamination: Use 0. 06-0. 1 mm thick film is laid on the excavated seedbed, close to the seedbed, and check for leaks and bubbles.
3, matrix loading plate: The matrix water spray to reach the group, the fingers do not flow, the drop of the natural spread into the seedling tray, so that the substrate jitter to 1-1. 5 cm from the disk surface.
4. Prepare nutrient solution: First mix 5kg of special fertilizer with water into the mother liquor and mix well. Fill the nursery pool and quickly add enough clear water to 150-200kg to make a uniform nutrient solution.
5, sowing: The treated seeds when the water temperature stabilized at 17 degrees above the seeding, germination (bud length can not exceed a cotton length) cotton seeds, sowing each one hole to the center of the disk hole, bud tip down.
6. Cover: cover 1-1. 5 cm with the substrate flush with the disk.
7. Disposal and Disinfection: Place the disc into the liquid immediately Disinfect the tray surface by spraying carbendazim and other fungicides.
8. Pre-emergence management: Generally, it is only necessary to cover small plastic sheds in the morning and evening on sunny days, and it is necessary to cover the membranes in rainy days. However, the ends of the arch sheds should be open and vents must be opened to achieve no fog within the membrane.
9, after budding management: Qimiao, do not rain do not cover film day and night, rainy days cover the top, surrounded by ventilation, when the dense flow of film insulation film or move the tray to the indoor anti-freeze damage, clear the film on sunny days to avoid high temperature Xiaomiao.
10. Shumiao seedlings and dig seedlings: After two true leaves, the roots can leave the nutrient solution and be interrupted by 1-2 hours. According to the situation, spray the miraculin or dialytamine (1 g each time) to prevent high levels. Foot seedlings. And timely control of pests.
11. Transplanting at the right time: Suitable for transplanting seasonally from 1 leaf heart to 3 leaf hearts, hybrid F1 spacing is 1-1. 2 meters, and plant spacing is 50-60 centimeters. When transplanting, the soil shall be transplanted after 4 o'clock on a cloudy day or sunny afternoon, and the water shall be poured (fixed root water).
