How to fertilize Sichuan pepper? The latest fertilization technique and method tutorial

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 Sichuan pepper be fertilized when planting it? Below, the editor brings you the fertilization techniques for Sichuan pepper. Let's take a look!

1. Base fertilizer

Base fertilizer is generally mainly composed of decomposed farmyard manure. 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, base fertilizer should be applied in autumn after the Sichuan pepper trees have been harvested and before the soil freezes. This is because Sichuan pepper trees enter dormancy in winter to overwinter, and applying sufficient base fertilizer in autumn allows the trees to absorb sufficient nutrients before entering dormancy. Improving the nutrient accumulation of Sichuan pepper can not only help the trees overwinter, but also increase the germination and flowering rate of the trees in spring and promote the growth of new shoots.

2. Topdressing

Before the Sichuan pepper trees sprout in spring, apply nitrogen fertilizer once appropriately in furrows, control the fertilizer amount according to the tree age and growth stage of the Sichuan pepper trees, spread it comprehensively and evenly into the fertilization furrows, and then cover it with a layer of fine soil. Then apply topdressing once more before flower bud differentiation, mainly with compound fertilizer, which can effectively promote flower bud differentiation of the Sichuan pepper trees and also promote the growth of the fruit, preventing the alternate bearing phenomenon. Then apply topdressing once each before and after flowering to meet the nutrients needed for flowering and fruiting. For trees with strong growth and high yield, control the application of nitrogen fertilizer to prevent excessive vegetative growth.

3. Fertilization methods

For densely planted Sichuan pepper orchards, fertilization needs to be comprehensive and even. Spread the fertilizer over the orchard ground, then 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 that each Sichuan pepper tree can have sufficient nutrients. Then, for Sichuan pepper orchards with intercrops and young trees, use fertilization methods such as ring application, radial fertilization and furrow application, generally mainly hole application. This can ensure that the nutrients are concentrated on the Sichuan pepper trees, enhance the growth ability of the 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 mass and fertilizer type 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, properly spraying foliar fertilizer can promote the growth of the 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 trees. Before the Sichuan pepper trees flower, we should appropriately spray urea and monopotassium phosphate and other easy-to-absorb fertilizers about 3 times, with an interval of one week. Then spray again during the flowering stage, full flowering stage and expansion stage to provide sufficient nutrients for flowering and fruiting.

The above is a brief introduction to the fertilization techniques for Sichuan pepper. Fertilizing Sichuan pepper is a necessary task when planting it. And we should reasonably choose the fertilizer type and fertilization amount according to soil fertility, tree age and growth stage, etc., to ensure the growth of the Sichuan pepper trees. That is all for today's introduction. This article is for reference only. Thank you for your reading and support.
