Fertilizer is the "food" of pepper. To make the peppers grow well, first give the peppers ample supply of "food." Pepper has a small amount of roots, weak regeneration, and weak absorption capacity. The pepper plants are generally taller and have more results. They need more water and fertilizer and are suitable for growing in fertile sandy loam soils or loam soils with high water and fertility, and good permeability. The root system of the pepper has the characteristics of wet and intolerant pods and fertilizer-incompatibility of concentrated fertilizer. This requires us to pay special attention to watering and fertilizing, follow the principle of "a small number of times", small water diligently, top-dressing, to reduce the damage to the roots of pepper.
Water is an important determinant of root growth. After the planting, the first few waters are poured well, which can promote deep rooting and improve the stress resistance of the root system. The root system of pepper is very sensitive to water accumulation. Scientific experiments have shown that when the water accumulated for more than 6 hours, the hairy roots began to die; over 24 hours, the whole root system of the pepper died. Therefore, when peppers are cultivated, small water should be poured each time except for planting water. The nutrients needed for different stages of peppers are different and need to be adjusted according to the different growth stages of the peppers. At the seedling stage, water and fertilizer requirements are minimal. Mainly vegetative growth requires more nitrogen. In the nursery substrate, more fertilizer is generally added to meet the needs of the seedlings. If there is a detoxification, it can be solved with water. From the fat absorption characteristics of the root system of pepper and the rule of fertilizer requirement, the root system of pepper is suitable for growing in soil with high organic matter content. Apply 8-12 cubic meters of fully cooked chicken and duck droppings per acre, deep turning, which will benefit the development of the root system. Pepper absorption of water and fertilizer is mainly concentrated in the result period, at this time to top dressing, can be applied with high potassium fertilizer compound.
