How to control the abnormality of pepper seedlings
Caused the abnormal development of pepper seedlings, first, the partial nitrogen fertilizer on the seedbed, the large seeding rate, the late seedlings; Second, the base fertilizer deficiency, drought water loss; Third, the cold caused by freezing; Fourth, even the long time of rain, no timely ventilation Fifth, after a long drought, watering is too much, and its physiological disorders. The normal growth of cotyledons is a sign of strong pepper seedlings, and strong seedlings are the basis for high yield of peppers. For pepper seedlings to grow robustly, conditions must be created to prevent abnormal seedlings from occurring. The bearing structure, fixed film systems and installation of this greenhouse is relatively simple. And due to it, raw material and manufacturing costs are affordable. Except the high strength woven film is higher, other kinds of antidrop film are economical. In general, the comprehensive cost of film greenhouse is lower 30% ~ 50% than the same size and specifications of the other types of greenhouse.

Prevention and control measures: First, we must adhere to the nutrition seedlings, organic fertilizers in the nutrient soil should account for 70%, while the appropriate amount of superphosphate should be applied, and superphosphate 1-2 kg should be added for every 1000 kg of nutrient soil; , Dry and wet, small dry and wet, sunny and more pouring, less cloudy or not pouring, cloudy, warming and more pouring, cooling and spraying the new high-fat membrane insulation and disease prevention and infection. During the transplanting process, the root water is poured, the new high fat film is sprayed to reduce the period of seedling sowing, and the seedlings are sowed and then watered once to promote seedling water. The third is to control the temperature scientifically. The shelf temperature should not be lower than 15°C and higher than 35°C; The brilliance of the photosynthetic seedlings meets continuous rain, and at noon they should be quickly discharged and light film fertilizers are used to increase the absorption of light energy.
