Fertilization method of dragon fruit

Dragon fruit is a typical tropical fruit, which has a wide planting area in the tropical provinces of our country. The cultivation of dragon fruit is inseparable from nutrition, so it is very important for us to apply fertilizer when planting. However, many friends do not know how to apply fertilizer when planting, resulting in lack of fertilizer and poor growth of dragon fruit. So today, the editor has brought you the method of fertilizing dragon fruit. Let's have a look!

1. Law of fertilizer requirement

The nutritional requirements of dragon fruit are determined according to the growth stage and tree age. for example, 1-2-year-old dragon fruit trees should be based on nitrogen fertilizer. Then for more than 3 years, the application of nitrogen fertilizer should be properly controlled and the proportion of phosphorus and potassium fertilizer should be increased. When fertilizing, use chemical fertilizer as little as possible, mainly organic fertilizer. Then before the dragon fruit tree blossoms, it is necessary to increase the phosphorus content of dragon fruit. As a result, you have to be fattened once in about 2-3 weeks. Only in this way can we fully meet the fertilizer requirements of dragon fruit, ensure the growth of dragon fruit and increase the yield.

2. Base fertilizer

The application of base fertilizer before planting is very important, and we should apply base fertilizer about 2 months before planting. The base fertilizer is mainly fully mature farm manure, and the amount should be controlled according to the planting area. If the soil is more fertile, the base fertilizer can be applied less appropriately. Let the soil and fertilizer be fully mixed to improve the soil fertility and promote the growth of seedlings after planting. Improve the survival rate of seedlings, enhance the growth, and control the growth rate of seedlings. Only by ensuring adequate nutrition can we ensure the normal growth of dragon fruit and expand its own planting benefits.

3. Topdressing

Before the dragon fruit trees blossom and bear fruit, the nutritional demand of dragon fruit is relatively high, so topdressing at this time can promote the growth of dragon fruit branches. Liquid fertilizer or farm manure was the main topdressing in seedling stage, and a small amount was mainly applied in topdressing. Then it is found that there are new branches sprouting and turning green when topdressing again. The topdressing of dragon fruit needs about 5 times a year, usually in the more important period of dragon fruit growth, such as flowering stage, early fruit stage and full fruit stage. It should be noted that the amount of fertilizer applied each year should be appropriately higher than that of the previous year.

4. Foliar fertilizer

Foliar fertilizer is mainly to promote the growth of dragon fruit leaves, the stems and leaves of dragon fruit trees show a triangular column, we should spray foliar fertilizer around this part, to ensure that the spraying is comprehensive and uniform. When spraying foliar fertilizer, it is mainly based on micro-fertilizer, and the proportion of nutrition in fertilizer is adjusted according to the growth stage. For example, boron and magnesium are the main elements in the early stage of the fruit, and calcium and iron are the main elements in the later stage. These elements can effectively improve the stress resistance of dragon fruit and improve the fruit quality.

The effect of foliar fertilizer spraying is more obvious than that of fertilization outside the root, which can make the nutrition enter the dragon fruit more quickly and prevent the nutrition from remaining in the soil. But the duration of the effect is relatively short. And pay attention to the amount of foliar fertilizer, otherwise it is easy to produce fertilizer damage, and foliar fertilizer can not be used as the main fertilization method, only auxiliary fertilization can ensure the growth of dragon fruit.
