First, nursery preparation: including four tasks, one is to build a shed. Conventional nursery uses cold bed Yangshuo or greenhouse. When making a bed construction shed, you should choose to shelter from the sun, the terrain is high dry, and the water source is convenient. The second is to prepare nutritional soil. Beds and loess soil should be piled with soil for 3 months. Generally, garden soil or river mud is used to add human fecal urine, chicken manure, and grass ash to make up nutrient soil to supply sufficient available nitrogen and phosphorus. Colder areas prepare warm stuff. The third is to improve the facilities conditions, such as the formation of greenhouses, multi-layered coverage, installation of geothermal lines, temperature control seedlings. The fourth is to prepare enough “no deep plowing†soil conditioners and Shuofeng 481 for timely application before sowing and in seedbed management. Second, germination sowing: sowing time can be based on the characteristics of the species, the date of planting and nursery conditions. Early pepper, eggplant should be in the middle and late October, tomatoes should be in mid-November. Seed disinfection before sowing, available 55 °C warm water soak for 15 minutes, when soaking, pay attention to constant stirring and cooling, and then 1 g of Shuofeng 481 3 kg of water immersion disinfection, early pepper, eggplant 7 hours, tomatoes 5 hours. Eggplant should pay attention to washing, repeatedly washing with water before germination, rubbing with sand, remove the mucus on the surface of the seed. The soaked seeds were drained, moistened, and placed in a 28-30°C incubator for germination. In order not to germinate the seeds too quickly, the temperature can be used to germinate, that is, keep 28-30 °C during the day, 16-18 °C at night, tomato 2 days, pepper 3-4 days, eggplant 5 days, the seeds can be sown white dew. Before seeding, the seedbed is poured into bottom water, and after the water is soaked, it can be sprayed “without deep ploughingâ€, 50 grams per 100 square meters, 12 to 15 kilograms of water, evenly sprayed on the surface of the soil, the bed soil becomes very moist and can be sown. seed. Cover it with fine soil and cover with plastic film. Sowing rate is 10 square meters, 100 grams of tomatoes and eggplant, and 150-200 grams of pepper. If it is a commodity seedling, it can be broadcasted or drilled without passing the seedling stage. Third, the seedbed management: sowing seed bed temperature day and night to maintain 25-30 °C, the basic Qimiao began to cool to prevent seedlings leggy, seedling growth period to maintain daily temperature 20-25 °C, night temperature 10-15 °C, ground temperature 20 °C, The relative humidity in the bed is about 70%. When 3-4 seedlings of seedlings are sub-seedlings, seedlings can be transplanted to the prepared nursery bed or transplanted to the prepared seedlings. When carrying out this work, choose sunny weather, preferably 25-28°C during the day and 18-20°C during the night. In order to promote rooting and survival, the temperature can be increased to 25-30°C (about 5 days) in the short term and the temperature is low. The survival rate of seedlings is significantly reduced, dead seedlings, inverted seedlings, yellow seedlings, rotted roots, etc. will all appear. When the seedling grows to 7 true leaves, it can be sprayed with feng feng 481 (the seedling can be used with feng feng 481 to irrigate the root). The concentration is 5 grams of fengfeng 481 to 30 kg of water. It should be noted that in the case of adequate bottom water, watering as little as possible before spring begins, rather dry and not wet, the amount of watering after spring can be slightly larger. Watering should take place on sunny days from 10 to 11 am. If the seedbed is too wet, it can be solved by means of ventilation, drying the bed, and spreading fine soil. The seedbed also needs ventilation to adjust the temperature and humidity and exchange fresh air. The amount of ventilation in the first half of the day is small to large, and when the wind is blowing, the vents are opened in the wind direction. During the whole seedling period, except for rainy days and days when the temperature is too low, the grass should be removed every day to extend the chance of seeing light. Long cloudy to clear, in order to prevent a sudden loss of water down seedlings, to be timely shade, more fertile bed soil, generally do not lack of fat, if the seedling growth stagnation and aging, can be used 2 grams of urea, potassium dihydrogen phosphate 20 grams of 10 kg of clean water , formulated into a nutrient solution for spraying, but can not be followed by concentrated manure or separate application of urea, ammonium sulfate and other fertilizers. In the greenhouses, greenhouses or other protective grounds for nursery, if the market is supplied as a commercial seedling, the seedling stage may not be passed, but the management still needs to strengthen the control of seedlings, and the dense seedlings must be removed to maintain the seedling distance and reach the seedlings Qi Qi, strong.
