Causes and preventive measures of empty pepper in greenhouse
Now that the temperature is gradually rising, coupled with the rainy weather, it is easy to cause the sweet pepper in the greenhouse to be empty due to the high temperature and high humidity. The stems and leaves of sweet peppers grow vigorously, but the result is not empty or the result is small. It is called empty space. The empty pepper will directly lead to the reduction of sweet pepper production and the economic benefits will be affected. What are the reasons for the empty pepper? What to do? How to prevent it? First, the reason for the empty bell pepper in the greenhouse The root cause of the empty bell peppers in the greenhouse is that the greenhouse is often hot and humid. The main reasons are the following two points. 1. Slow seedling period is too long The slow seedling period is generally 6~7 days. During this period, it is required to seal the greenhouse, and it can not be ventilated. The temperature of the shed is maintained at 30~35 degrees. At night, the curtains are covered with straw curtains for heat preservation and antifreeze to accelerate the slow seedling. However, if the slow seedling period is too long, the high temperature and high humidity duration in the greenhouse will prolong, which will easily cause the plant to grow in a "false" state. 2, ventilation is not timely Ventilation should be timely ventilation, so that the temperature of the shed is reduced to 28~30 degrees, and then the ventilation temperature should be lowered every time the shed temperature is higher than 30 degrees. Otherwise, the temperature in the shed is high, the evaporation of soil moisture is accelerated, the transpiration of the plant is strengthened, and the humidity in the shed is much higher than 60%. The first door is difficult to sit on, and once the fourth fruit is unable to sit, the nutrient is It will concentrate on the growth of branches and leaves, which will further exacerbate the plant's length, causing a vicious circle and eventually forming an empty space. Second, the prevention measures for empty greenhouse sweet pepper 1. After planting, it is necessary to seal the greenhouse tightly and cover the straw at night to promote the slow seedling. 2. After the seedlings are slowed down, under the condition of maintaining a certain temperature, it is necessary to ventilate boldly to reduce the humidity in the shed. Maintain the shed temperature of 28~30 degrees in the initial stage, and then slowly reduce the shed temperature standard, and keep it at 20~25 degrees until the flowering and fruiting period. When the minimum temperature of the outside is not less than 15 degrees, ventilation should be carried out day and night, so that the growth of the sweet pepper plant is short, the internodes are short, and there are many fruit sets. 3. Strengthen water and fertilizer management The leaves of sweet pepper are small, and the amount of water transpiration is not large. When planting, do not water too much. After the seedlings are harvested, it is generally not easy to water before harvesting. Otherwise, it is easy to cause falling flowers and fruits. When the first layer of fruit begins to harvest, it is necessary to strengthen watering, fertilization, multi-application of organic fertilizer, and application of phosphorus and potassium fertilizer to facilitate the high yield of sweet pepper and improve fruit quality. The above is the reason and preventive measures for the empty bell pepper in the greenhouse. The demand for sweet pepper is currently on the market. Most of the sweet peppers on the market are grown in greenhouses. If the farmers who grow sweet peppers in the greenhouses are also open, they can master the above preventive measures to avoid the empty peppers and reduce unnecessary losses.
