Pepper is an indispensable kind of seasoning vegetable in our daily life. The planting area of ​​pepper in China is also increasing. Now it is the seedling stage of pepper. This stage can effectively promote the growth of pepper seedlings and the high yield of pepper. The amount lays a solid foundation. So what are the precautions for pepper seedlings? How to prevent it? 1, pay attention to avoid seeding after seeding The suitable temperature for pepper seed germination is 20-28 degrees. The temperature is lower than 15 degrees. The germination is slow. If it is lower than 10 degrees, it can not germinate. In the normal temperature, the germination period is 12 days. The seeds are inspected within a certain time, such as the seed embryo is white and Fresh, no buds, it may be due to the unconditional conditions of the seedbed, so that no seedlings should be raised. Try to raise the bed temperature. The soil of the seedbed should be properly watered. If the seedbed is too wet, it can be planted with some ash. If the seed is rot, it should be replenished in time. 2, pay attention to avoid the freezing of pepper seedlings During spring nursery, the weather temperature is very unstable. If there is a cold spring, the temperature drops suddenly, or there is a long period of low temperature and rainy weather, the pepper seedlings are prone to freezing damage. Mainly manifested as necrotic white spots or yellowish spots on the young leaves at the top of the seedlings. In severe cases, the leaves and stems will also be water-stained, and then gradually dry and die. Control method: (1) The weather forecast should be closely monitored. Actively take effective measures to prevent freezing damage and increase coverage in seedling beds. (2) Enhance the cold resistance of pepper seedlings. Covered with straw curtains at night, the sun can uncover the straw curtains, and often beat the plastic film, let the water drops flow down to increase the light, increase the temperature, manage the temperature difference, promote the development of the pepper seedlings, such as the bed temperature is too high, Sprinkle some hay wood ash. (3) Foliar fertilization. Sprinkle 10% brown sugar water or glucose water with pepper water or 15 kg water to the pepper seedlings to enhance cold resistance. Spraying 0.5% calcium fertilizer solution in the four-leaf stage can significantly improve the cold resistance of pepper seedlings. 3, pay attention to avoid the emergence of "high seedlings" "High-legged seedlings" are formed by the growth of pepper seedlings. The reason is that the temperature is too high, the humidity of the seedbed is large, the seeding density is not scientifically increased, the amount of nitrogen fertilizer is applied, and the ventilation of the seedbed is poor. Control method: carry out temperature difference management, maintain 17 degrees during the day, maintain 10 degrees at night, prevent and control watering, the seeding amount should be reasonable, apply nitrogen fertilizer reasonably, and gradually increase the air release as the temperature rises. If there is a phenomenon of length, you can use 3.5 grams of paclobutrazol to spray 15 kilograms of water, which can promote seedling growth and reach the standard of strong seedlings. 4, pay attention to prevent disease during nursery The disease of pepper seedlings is mainly tripping, blight, gray mold, and epidemic diseases. The fungal bacteria of these diseases cross-occurate, and can be alleviated by seed disinfection and seedbed disinfection. Control method: It can be sprayed with 75% chlorothalonil, 50% thiophanate, 72% agricultural streptomycin, 40% muscarinic acid or 70% fluoromanganese zinc. The disease of pepper seedlings must follow the principle of “prevention first, comprehensive prevention†to prevent the occurrence of peppers. The above is the precautions and prevention methods of spring pepper seedlings. Seedling cultivation is an important stage of pepper growth and development. This period is also an important stage of vegetative growth and reproductive growth of pepper, which has a great influence on the yield and quality of pepper. Therefore, farmers must pay attention.
