Pepper seedling management technology
1. Seed treatment Seed sowing before planting 1 to 2 days, with hot water 52 ~ 55 °C for 15 minutes (with constant stirring and heating water to maintain the temperature to ensure sterilization), and then soaked in warm water for 3 to 5 hours, then use 10% phosphoric acid Trisodium 1000 times solution soaked in water for 10 minutes, washed with water, removed and drained, wrapped in moist cloth at 30 °C germination (turning 3 to 4 times per day) until the seeds exposed white sowing. 2. Soil preparation Choose sheltered sunny, well-drained, fertile soil, 1 to 2 years did not plant land planting Solanaceae crops, seedlings can be nursery beds or nutrition cups, the best nutrient cup seedlings. 1 Seedling nursery: After breaking up the upper layer of soil, mix it with appropriate amounts of decomposed organic fertilizer and a small amount of phosphate fertilizer, spread the seeds evenly on the seedbed, and cover the seed with a thin fine soil to a thickness of about 0.5 cm to cover the straw or shade net. After pouring water. The amount of seeds used for seedbeds is 10 to 15 grams per square meter, and the amount of seeds used per acre of pepper is 50 to 80 grams. 2 Nutrition Cup Nursery: It is recommended to use a seedling cup with a caliber of about 8 cm, sow 2 to 3 seeds per cup for individual seedlings, 3 to 4 seeds for each cup of double seedlings, cover with a shade net or straw and then coat permeable. The general spring planting is planted from November to February of the following year. The autumn planting is planted from mid-July to early August, and the autumn and winter planting of the western part of Guangdong is planted in late August-September. 3. Seedling management Seed germination temperature is 25 ~ 30 °C, the seedling bed before the emergence of heat preservation and moisturizing, promote seedlings, Qi Miao. Winter and spring exposed nursery needs to build a small shed for insulation. After emergence, attention should be paid to adjusting the humidity of the seedbed, and it is necessary to have sufficient moisture and not be too wet. After the cotyledon is fully expanded, the first time the seedlings are made, and the first seedlings of the seedlings are 2 to 3 true leaves for the second time. When the young yellow leaflets show a lack of fertilizer, they need topdressing, and can apply 0.2% compound fertilizer water in the sunny afternoon. Applying compound fertilizer water and spraying a bactericidal agent to prevent disease 1 to 2 days before transplanting can speed up seedlings after planting, and reduce the chance of infection and disease caused by root injury.
