How to fertilize wampee

Wampee is native to southern China and is a tropical and subtropical evergreen fruit, which is one of the best fruits in Lingnan. With its promotion, its growers and planting area continue to expand, but there are a lot of problems in planting. Among them, the blindness of fertilizer and water management leads to its low yield, so how to fertilize wampee? Let's take a look.

Fertilization for young trees

The root system of young wampee trees is underdeveloped and the absorption is weak before distribution, so we should pay attention to the concentration when fertilizing young trees, so as not to burn the roots of young trees, resulting in root damage and affect the growth of young trees. Young tree fertilization should grasp the principle of frequent application and thin application, mainly nitrogen fertilizer, combined with phosphorus and potassium fertilizer and micro-fertilizer to promote the growth of young trees. Young trees can be fertilized after one month of survival, and then fertilized once every time the new shoots germinate and turn green. In addition, organic fertilizer should be applied during overwintering to improve the survival rate of overwintering and make them survive the winter safely.

II. Fertilization for mature trees

1. Fertilization after fruit harvest

At this time, the amount of fertilizer application is relatively large, depending on soil fertility, plant fruit amount and tree age, the method of water application of mature bran can be used, 15 kg per plant, drenching in shallow ditches around the crown or directly near the root system. You can also use the method of applying dry fertilizer, 200-300 grams of ternary compound fertilizer or 200 grams of urea per plant.

2. Fertilization for autumn shoots

In order to promote the ripening and secondary germination of autumn shoots after autumn shoot germination, 200-300 grams of ternary compound fertilizer could be applied to each plant.

3. Chemical fertilizer for flower bud differentiation

Before and after Greater Cold, in order to promote flower bud differentiation and accelerate the growth and development of floral organs and fruiting branches, 20-30kg of rotten organic fertilizer was applied to each plant, first digging holes around the plant and backfilling one layer of soil.

4. Fertilization at full flowering stage

In the peak period of plant flowering, in order to supplement a large number of nutrients consumed by flowering and make the plant blossom and bear more fruit, 150-200 grams of compound fertilizer can be applied per plant, and the leaves can also be made green.

5. Fertilization during fruit expansion

In the fruit expansion period, in order to speed up the fruit growth and improve the yield and quality, it is generally applied after physiological fruit drop, applying 150-200 grams of compound fertilizer per plant, and a small amount of boron or potassium fertilizer can be added, which can obviously increase the yield.

The above is the introduction of how to apply fertilizer. I hope it can help you. If you want to know more about it, please follow us.
