How to Fertilize Sichuan Pepper? Detailed Explanation of the Key Points of Scientific Fertilization Techniques
Sichuan pepper is a very common side ingredient in China, mainly used for seasoning and stimulating the appetite, and it is very popular in provinces such as Sichuan and Chongqing. China also has a large planting area of Sichuan pepper, and when planting Sichuan pepper, doing a good job in field management is essential. Among these, fertilization is the top priority. So how should fertilization be done when planting Sichuan pepper? Below, the editor brings you the fertilization techniques for Sichuan pepper. Let's take a look together!
1. Base fertilizer
Base fertilizer is generally mainly decomposed farmyard manure, and an appropriate amount of base fertilizer can enhance soil quality and improve soil structure. Adding an appropriate amount of nitrogen fertilizer to farmyard manure can improve the effect of the fertilizer. Generally, the base fertilizer should be applied in autumn after the Sichuan pepper trees are harvested and before the ground freezes. This is because Sichuan pepper trees enter dormancy in winter to overwinter, and applying sufficient base fertilizer in autumn allows the Sichuan pepper trees to absorb sufficient nutrients before entering dormancy. Improving the nutrient accumulation of Sichuan pepper can not only help the Sichuan pepper trees overwinter, but also increase the germination and flowering rate of the Sichuan pepper trees in spring and promote the growth of new shoots.
2. Topdressing
Before the Sichuan pepper trees sprout in spring, a appropriate amount of nitrogen fertilizer should be applied in furrows once, and the fertilizer amount should be controlled according to the tree age and growth stage of the Sichuan pepper trees, spread fully and evenly into the fertilization furrow, and then covered with a layer of fine soil. Then topdress once more before flower bud differentiation, mainly with compound fertilizer, which can effectively promote flower bud differentiation of the Sichuan pepper trees, and can also promote the growth of Sichuan pepper fruits and prevent the phenomenon of alternate bearing. Then topdress once each before and after flowering to meet the nutrients needed for flowering and fruiting of the Sichuan pepper trees. For trees with strong growth and high yield, the application of nitrogen fertilizer should be controlled to prevent excessive vegetative growth.
3. Fertilization methods
For densely planted Sichuan pepper orchards, fertilization needs to be comprehensive and uniform. After spreading the fertilizer on the orchard ground, mix it thoroughly and evenly with the soil, and deep plow about 20 cm. This is generally done together with intertillage in spring and autumn, so as to ensure that each Sichuan pepper tree has sufficient nutrients. Then, for some Sichuan pepper orchards with intercrops and young trees, fertilization methods such as ring application, radial fertilization and furrow application are used, generally mainly hole application. This can ensure that nutrients are concentrated on the Sichuan pepper trees, enhance the growth ability of the Sichuan pepper trees, and avoid excessive growth of intercrops affecting the growth of the Sichuan pepper trees. Then when fertilizing, we should pay attention to controlling the depth according to the root group and the type of fertilizer to improve the utilization rate of the fertilizer.
4. Foliar fertilizer
Although foliar fertilizer is not a fertilizer necessary for the growth of Sichuan pepper trees, proper spraying of foliar fertilizer can promote the growth of Sichuan pepper trees and increase yield. This is because foliar fertilizer can improve the growth ability of leaves, enhance the photosynthetic capacity of leaves, and increase the accumulation of photosynthetic substances in the Sichuan pepper trees. Before the Sichuan pepper trees bloom, we should properly spray urea and potassium dihydrogen phosphate and other easy-to-absorb fertilizers about 3 times, with an interval of one week. Then spray again at the flowering stage, full flowering stage and swelling stage to provide sufficient nutrients for the flowering and fruiting of Sichuan pepper.
The above is a brief introduction to the fertilization techniques for Sichuan pepper. Fertilization of Sichuan pepper is a necessary task when planting Sichuan pepper. And we should reasonably choose the type of fertilizer and the amount of fertilization according to the soil fertility, the tree age and growth stage of the Sichuan pepper trees, so as to ensure the growth of the Sichuan pepper trees.
