At the end of summer and early autumn, the weather is hot and the light is strong, which brings certain difficulties to the nursery. However, the friends of the amaranth farmers pay attention to the technical operation process, so that the seedlings can be taught and the management is scientific. The following measures are taken to ensure the growth of the pepper seedlings. Strong and strong. Xiaqiu pepper seedlings are good at solving problems such as high temperature and drought, heavy storms, prevention of seedlings, prevention of pests and diseases, etc., while doing a good job in seed treatment, natural room temperature germination, and selection of tray seeding. Seed treatment: After selecting the good variety, the seeds are dried for 4 hours, then disinfected by trisodium phosphate solution, and then soaked in water for about 8 hours. After the fish is removed, it is slightly dry and ready to germination. Normal temperature germination: The room temperature is usually around 30 °C, which is the appropriate temperature for germination. Wrap the soaked seeds in cotton and apply a layer of plastic film to moisturize. Rinse the seeds with water every half day, then pack the seeds and bud them for about 60 to 70 hours. When the bud length is about 3 mm (this time the seed is white), the seeding is best; if it cannot be sown in time, the seed should be stored at about 8 °C, and the seeding conditions should be created as soon as possible. Preparation of the tray: Select the special seedling medium, each bag can hold 12 trays of 72 holes, and 72 seedlings per dish. The 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 then mix well. After the plate is leveled (scrape with a straight wooden board). This is the beginning of the nursery work. It is still important to raise the seedlings. It is the top priority of the whole work to prevent high temperature and drought, heavy rain and water, seedlings and pests. Prevention of high temperature: After sowing, the trays are irrigated with water and combined with spray Pulik, and then covered with mulch to moisturize. At this time, attention should be paid to shading and cooling, so as to prevent steaming of seeds and affecting emergence. At this time, 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 seedlings grow, the time to cover the shading net can be shortened, which is more conducive to seedling growth. Prevention of drought: After sowing seedlings, always pay attention to the humidity of the seedbed, not too wet or too dry. Many vegetable farmers are afraid that the seedlings are long and control the watering, which causes the trays to be excessively dry. At this time, the capillary roots are damaged due to water loss and drought, affecting the absorption later. Ability to form weak seedlings and easy to get sick. Therefore, to properly water, watering time should be the best on a sunny morning. Prevention of seedlings: No matter what crops are grown, it is because of poor light conditions, low light cooperation, high temperature and high humidity. The main reason for summer pepper seedlings is because the night temperature is high, the breathing is strong, and the nutrients are consumed too much. Then the nitrogen fertilizer and water are sufficient to cause the seedlings to grow. In addition, the seedlings are too dense to block the sunlight, affecting photosynthesis. Therefore, prevention of seedlings should be careful 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 applied less; 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 avoid seedlings. Prevention of heavy rain hazard: The seedbed is set in the shed, generally adopting a membrane and 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 rainwater on the seedlings. Draining and rain-borne germs. Prevention of pests and diseases: At this stage, because the external environment is more conducive to the occurrence of pests, it is also necessary to strengthen the prevention and control of pests. For example, a strict insect-proof net is set in the nursery shed; the traits of pests are used to set up yellow boards to induce cockroaches, to attract white mites, to trap cockroaches with blue boards, etc.; At this time, the disease that should be strengthened is the virus disease in the seedling stage, the blight disease and the mid-growth virus. In addition to the seed disinfection, the seedbed disinfection is also carried out, and the seedlings can be sprayed to the farm No. 4 or the seedlings after sowing. Mixing into the harvest of No.1 can not only effectively inhibit the disease of soil-borne seedling stage, but also promote the development of root system during seedling stage.
