After the pepper is harvested, it is advisable to apply the base fertilizer as soon as possible. Because the roots of autumn peppers are at another peak of growth, it is a key period for the annual fertilization of peppers, and it is necessary to apply the base fertilizer as soon as possible.
First, early application of base has the following advantages:
1. Due to the vigorous activity of the roots of the pepper, the roots are easy to heal, and new roots are quickly produced, which increases nutrient absorption.
2. In autumn, there is more rain, the soil moisture is high, the ground temperature is suitable, the microbial activity is strong, the organic matter is decomposed quickly, the mineralization degree is high, and it is easy to be absorbed and stored by the root system.
3. The new shoots of pepper have been basically stopped for a long time. After the application of the base fertilizer, the quick-acting part can be absorbed and utilized by the roots. Not only the photosynthetic function of the strong leaves, but also most of the photosynthetic products can be stored in the tree body to enrich the flower buds. Full, the accumulation of nutrients in the branches is more conducive to safe wintering. The long-acting part of the base fertilizer, such as most of the complex organic matter, is transformed into a nutrient that is easily absorbed by the roots after long-term decomposition. It plays a fertilizer effect in the spring germination of pepper, enhances and promotes the growth and development of the tree, and is beneficial to high yield.
4, early application of base fertilizer, can also improve the quality of flower buds, enhance the cold resistance of the tree.
Second, the type of base fertilizer The base fertilizer type is mainly organic fertilizer, mixed with appropriate phosphate fertilizer. Organic fertilizers include farmyard manure, manure, pond mud and pepper seed fermented fertilizer. The amount of fertilization is generally sapling (3-5 years), 20-50 kg of organic fertilizer mixed with phosphate fertilizer 0.3-0.5 kg. The mature tree plant is applied with 50-100 kg of organic fertilizer and 1-2 kg of phosphate fertilizer.
Third, the fertilization method In the vertical projection of the canopy, that is, 1 to 1.5 meters away from the main fertilization, can be adapted to local conditions, using annular groove casting, strip-shaped ditch casting. The groove depth is 25-40 cm and the width is 30-50 cm.
