How to grow pepper seedlings
Chili peppers are a popular seasoning vegetable, and the quality of seedling seedlings directly affects the yield in the later period. Many novice growers often fail to raise seedlings due to incomplete disinfection and improper temperature control. This article will systematically analyze the complete technical chain from time selection to sowing management to help you cultivate strong pepper seedlings. The best seedling breeding time for the four-step core process of pepper seedling breeding is controlled to be 15-20 days after the beginning of autumn (the average daily temperature is about 25℃). At this time, the temperature difference between day and night is less than 8℃, which not only avoids stagnant water and rotten roots in the rainy season, but also reduces the incidence of viral diseases. The northern region can be extended to late August, using small arched sheds to assist in temperature control. Scientific disinfection and treatment of seedbed disinfection: plowing 30cm deep 15 days in advance, mix decomposed sheep manure in a ratio of 2:1, and spray 2L of 800 times 50% carbendazim per square meter. Seed treatment: Adopt the "three-temperature disinfection method"-expose to sunlight for 48 hours → soak in warm water at 55℃ for 15 minutes → soak in 0.5% potassium permanganate solution for 25 minutes, and finally germinate in warm water at 28℃ for 12 hours. The precise sowing process adopts the "three-sowing and two-covering" sowing method: first, evenly sow the seed with a fine-perforated sieve (grain spacing is 2cm) and cover it with 0.5cm of nutritious soil; second sowing of plant ash to prevent disease, and finally covering it with 0.5cm of vermiculite. It is recommended to use bamboo strips inserted in the shape of "pin" to support the mulch film, and keep the temperature inside the film at 28-32℃ and the humidity at 75%. Key details of seedling management When the emergence rate reaches 60%, the film will be removed to refine the seedlings, and the film will be opened for ventilation from 10 to 14 o'clock every day. After the real leaves are unfolded, spray 0.2% potassium dihydrogen phosphate and irrigate the roots with microbial inoculants. Pay special attention to the prevention and control of catathing disease, and you can spray Trichoderma harzianum with 300 times liquid.
By strictly controlling the disinfection process, accurately controlling temperature and humidity, and scientific fertilizer and water management, the success rate of pepper seedling breeding can be increased to more than 90%. It is recommended to adopt a new seedling cultivation process with seedling tray + substrate, which can not only effectively isolate soil-borne diseases, but also achieve zero root injury after transplanting.
