Changing Seedling Raising Method to Cultivate Strong Seedling of Pepper

It is the season of pepper seedling, seedling is an important link in pepper cultivation, the quality of seedlings is directly related to the level of pepper yield. At present, many farmers still use traditional methods when breeding pepper seedlings, resulting in poor seedling quality. If you want to cultivate strong pepper seedlings, you need to change the seedling method. The change of not sunning seeds before sowing to sunning seeds can not only improve seed germination rate and enhance germination potential, but also kill part of germs on seed surface and reduce the occurrence of pepper diseases. The seeds should be placed on a cloth for 3 days on a sunny day, and they should be evenly diluted and turned over frequently. Water and salt water are used to select the seeds instead of the unselected seeds, so that the selected pepper seeds are uniform and plump, have strong germination potential, grow strongly, germinate and differentiate early, and are easy to grow into strong seedlings. The seeds treated with chemical agents have developed roots and strong green plants, which can enhance their ability to resist seedling diseases such as blight, damping-off disease, blight and anthracnose. 3% difenoconazole suspension seed coating agent 1∶300 times, or 75% darkonine wettable powder 500 times solution soaking for 30 minutes. Although there are many advantages in changing germination before sowing to non-germination, such as rapid emergence after sowing and neat emergence, the seeds after germination are easy to adhere during sowing, which is not conducive to sparse sowing and uniform sowing, and in the operation process, it is easy to cause broken buds and increase the chance of infection. Soaking seeds without germination before sowing can reduce the chance of pathogen infection and help prevent disease. Changing spring soil preparation to seedbed for autumn soil preparation to seedbed in autumn can improve soil ripening effect in autumn field, enhance soil nutrient release capacity and water retention, reduce damage degree of pepper seedling diseases and insect pests, and seedbed soil does not return to saline-alkali, which is beneficial to cultivating strong seedlings. Chicken manure as base fertilizer is changed into high-quality organic fertilizer. Chicken manure as base fertilizer is easy to burn seedlings, return salinization of soil, serious soil-borne diseases, and complicated procedures for chicken manure retting and disinfection, which make it difficult for most farmers to meet technical requirements. Using high-quality organic fertilizer as base fertilizer can not only adjust acid and alkali, eliminate soil-borne diseases, but also be convenient to use and save labor and effort. The medium shed was used to raise seedlings in small shed, which had large area and good ventilation and light transmission conditions, and could enhance the stress resistance of pepper seedlings. The temperature of seedbed increased by 0.5℃~0.8℃, and the light condition and temperature change were better than those covered with common colorless film. It was very beneficial to cultivate strong seedlings of pepper. The pepper seedlings were easy to become "cattle hair seedlings", the survival rate was low, the branches were few and the flower bud differentiation was late after transplanting. Sowing sparsely and evenly can make pepper seedlings have proper nutrient growth area, good ventilation and light transmission, and create a good growth environment for pepper seedlings. In order to cultivate proper seedlings, it is necessary to raise seedlings in time, keep the seedling age at 55~60 days, and keep the steady growth of pepper seedlings. Moreover, topdressing and auxin spraying should not be adopted to promote the rapid growth of pepper seedlings.
