How to Fertilize Wampee? Detailed Explanation of Fertilization Methods and Key Points

Wampee (Clausena lansium) is native to southern China and is a tropical and subtropical evergreen fruit unique to the southern region. It is one of the fine fruits of Lingnan. With its promotion, the number of people growing it and the planting area have continued to expand, but many problems have also arisen during cultivation. Among them, the blindness in fertilizer and water management leads to low yields. So how should wampee be fertilized? Let's take a look together.

I. Fertilizing Young Trees

The root system of young wampee trees is not well developed and is shallowly distributed, with weak absorption capacity. Therefore, when fertilizing young trees, attention should be paid to the concentration to avoid burning the roots with concentrated fertilizer, which would damage the root system of young trees and affect growth. Fertilizing young trees should follow the principle of frequent light applications, mainly with nitrogen fertilizer, combined with phosphorus and potassium fertilizers as well as trace element fertilizers, to promote the growth of young trees. Young trees can be fertilized 1 month after planting and surviving. After that, fertilize once each time new shoots sprout and each time new shoots turn green. In addition, during overwintering, increase the application of organic fertilizer to improve the overwintering survival rate and help them overwinter safely.

II. Fertilizing Mature Trees

1. Fertilizing After Fruit Harvest

At this time, the fertilization amount is relatively large, determined specifically according to soil fertility, fruit yield of the plant, and tree age. The method of watering with decomposed bran water can be used, applying 15 kg per tree, by opening shallow furrows around the canopy and drenching, or directly drenching near the root system. The method of applying dry fertilizer can also be used, applying 200-300 g of ternary compound fertilizer or 200 g of urea per tree.

2. Fertilizing for Autumn Shoots

After autumn shoots sprout, in order to promote the maturity of autumn shoots and promote the second sprouting of autumn shoots, and to cultivate fruiting branches, 200-300 g of ternary compound fertilizer can be applied per tree.

3. Fertilizer for Flower Bud Differentiation

Around Major Cold (Dahan), in order to promote flower bud differentiation and accelerate the growth and development of flower organs and fruiting branches, apply 20-30 kg of decomposed organic fertilizer per tree. First dig holes around the plant, then backfill with one layer of fertilizer and one layer of soil.

4. Fertilizing at Full Bloom Stage

During the peak flowering period of the plant, in order to supplement the large amount of nutrients consumed by flowering and enable the plant to bloom and bear more fruit, 150-200 g of compound fertilizer can be applied per tree, which can also keep the leaves emerald green.

5. Fertilizing During Fruit Enlargement Stage

During the fruit enlargement stage, in order to accelerate fruit growth and improve yield and quality, fertilization is generally applied after physiological fruit drop, with 150-200 g of compound fertilizer per tree. A small amount of boron fertilizer or potassium fertilizer can also be added, which has an obvious yield-increasing effect.
