Growth characteristics of pepper. Pepper is a thermophilic crop, and the suitable growth temperature is around 28℃. However, after planting, the seedlings can adapt to a wide temperature range, can also withstand high and low temperatures, and have low requirements for light. Under normal circumstances, flower bud differentiation can be completed, and the time of flower bud differentiation will be earlier. When the seedlings grow to three leaves, the flower buds begin to differentiate, indicating that the demand for fertilizer is earlier and the fertilizer tolerance is better. Pepper is planted, but it is drought-resistant and waterlogging-tolerant. When the air humidity is about 70%, the fruit setting rate is relatively high. After the rainy season, peppers will have a second growth period. At this time, it is necessary to replenish fertilizer in time. In order to obtain high yield of pepper, it is necessary to create suitable growth conditions to meet the growth needs of pepper and give full play to its growth potential. Although pepper has good fertilizer tolerance, it is easy to suffer fertilizer damage when it exceeds the limit. Therefore, formula fertilization must be carried out.

Every 2,000 kilograms of pepper needs 6 kilograms of nitrogen fertilizer, phosphorus pentoxide 1 kg and potassium oxide 10 kg. At the same time, it is necessary to use medium and trace element fertilizers and increase the use of inorganic fertilizers and organic fertilizers. How to improve fertilization technology in pepper planting to create conditions for high yield of pepper? Choose plots with good drainage to grow peppers. It is necessary to prepare high-standard land and ditches to prevent water accumulation. Is it a matter of fertilization that the yield of pepper can go up or down? In learning formula fertilization, organic fertilizer is used as the main base fertilizer, and 5 tons of fully decomposed soil fertilizer or 3 tons of fully decomposed chicken manure are used per mu of land, or 400 kilograms of organic fertilizer is purchased at the farmhouse store, or 180 kilograms of bio-organic compound fertilizer is used.

Water and fertilizer management is a very important link in the growth of pepper, but many growers pay more attention to the application of fertilizer, often ignoring the importance of watering and irrigation, while pepper is sensitive to water demand, and the water demand of pepper is different in several different growth periods. Pre-growth stage: In addition to thorough watering, the amount of watering at other stages should not be too much, otherwise it will affect root development; Prosperous period: at this stage, the leaves of pepper become larger and the growth rate is accelerated, which requires maximum watering; Late growth stage: when pepper leaves enter the yellowing stage, the photosynthesis and transpiration of leaves decrease, and the watering amount naturally decreases; Therefore, pepper watering is a step-by-step process, which cannot be achieved overnight, and the same amount of water cannot be used at different stages.

Otherwise, the water absorption of seeds is uneven, and the germination rate is reduced, which will not affect the growth ability of seeds. Seedling stage: Pepper seedling stage is fragile. At this time, a little watering will affect the permeability of the soil, leading to lack of oxygen in the root system and the phenomenon of dead roots and rotten seedlings. In addition, excessive soil moisture will cause various diseases and affect the growth of pepper at seedling stage. Flowering and fruiting period: During the flowering and fruiting period of pepper, it is necessary to gradually increase the amount of watering, because the growth of flowers, fruits and leaves all needs the support of water. Insufficient watering will lead to less fruits and deformed fruits. However, if the soil moisture is too much, it will lead to falling flowers and fruits, and the seedlings will rot, so it is necessary to grasp the amount of watering. Before the picking period: when the pepper grows to the final stage, the leaves gradually wither and turn yellow, and the fruit is basically mature. At this time, the amount of watering will be reduced, so as not to affect the growth of roots and promote the occurrence of diseases.
