1. Seed treatment: After selecting the good type, the seeds are exposed to the sun for 4 hours, then disinfected by the trisodium phosphate solution, and then soaked in water for about 8 hours. After the fish is removed, it is slightly dry and ready for germination.
2, room temperature germination: now room temperature is generally around 30 ° C, is the appropriate temperature for germination. Wrap the soaked seeds in cotton and apply a layer of plastic film to moisturize. Wash the seeds with clean water every half time, then pack the germination, and sprout about 60 to 70 hours. When the bud length is about 3 mm (the seed is white at the moment), the cultivation is best; if it cannot be cultivated in time, the seed should be stored at about 8 °C, and the cultivation conditions should be invented quickly.
3, the preparation of the tray: the use of special seedling medium, each bag can hold 72 holes 72 trays, 72 seedlings per dish, vegetable farmers can calculate the number of seedling trays and seedling media needed according to their own needs. . Mix the seedling medium with an appropriate amount of phosphorus-potassium compound fertilizer, special biological micro-fertilizer and other trace elements, and mix it evenly. After the plate is leveled (scrape with vertical wooden boards), cultivate.
4, to prevent high temperature: after the cultivation, the tray is poured through the water and combined with spray Pu Leke, and then cover the film to moisturize. At this moment, you should pay attention to shading and cooling, beware of steaming the seeds and affecting the emergence of seedlings. At this moment, the daytime temperature should be below 30 °C, and the nighttime temperature should be below 18 °C. When the seedlings are about 80%, the film can be removed. As the wheat grows, the time to cover the shade net can be shortened, which is more conducive to the growth of the wheat seedlings.
5, to prevent drought: after the emergence of seedlings, always pay attention to the humidity of the seedbed, do not be too wet or too dry, many vegetable farmers are afraid of the seedlings long and control the sprinkling water to form a plate over-fire and drought, at this moment due to capillary root loss and drought, affecting the future absorption Ability to form weak seedlings, simple feelings. Therefore, it is necessary to sprinkle water properly, and the time of watering should be optimal on a sunny morning.
6, to prevent the growth of seedlings: no matter what crop plants are long due to poor light conditions, low light cooperation, high temperature, humidity and so on. The main reason for the summer pepper seedlings is because of the high temperature at night, the strong respiration, and the excessive consumption of nutrients, and then the nitrogen fertilizer and water are sufficient to form the seedlings. In addition, the seedlings are too close to each other to block the sunlight, affecting photosynthesis. Therefore, it is necessary to prevent the seedlings from paying attention to prevent the night temperature from being too high, and the humidity in the tray is too large; then, when the watering is applied, the nitrogen fertilizer is less applied; the third is to increase the spacing of the trays when the seedlings grow to a certain size. Ventilation and light transmission, enhance photosynthesis to prevent seedlings from growing.
7, to prevent rainstorm damage: the seedbed is set in the shed, generally choose a membrane two net cover method (plastic film plus shade net and insect net) When there is heavy rain, the shed film can be pulled down and buried to prevent rain The seeds are washed and the rain conveys the germs.
8. Prevention of pests and diseases: At this stage, because the external environment is more conducive to the onset of pests, the prevention and control of pests should also be strengthened. For example, a tight insect-proof net is set in the nursery shed; the use of pests is characterized by the yellow plate attracting, attracting white powder, and using blue plates to trap the thrips; if necessary, chemical control should be used.
