A Complete Analysis of the Latest Fertilization Methods for Dragon Fruit
Dragon fruit is a typical tropical fruit and is widely planted in the tropical provinces of our country. The cultivation of dragon fruit cannot be separated from nutrients, so fertilization work is very important when we plant it. However, many friends do not know how to fertilize when planting, which leads to poor growth of dragon fruit due to lack of fertilizer. So today, the editor has brought you the fertilization methods for dragon fruit. Let's take a look together!
1. Fertilizer requirement rules
The nutrient requirements of dragon fruit are determined by the different growth stages and tree ages. For example, for 1-2 year old dragon fruit trees, nitrogen fertilizer should be the main fertilizer. Then for those more than 3 years old, the application of nitrogen fertilizer should be properly controlled, and the proportion of phosphorus and potassium fertilizer should be increased. When fertilizing, use chemical fertilizers as little as possible, with organic fertilizer as the main fertilizer. Then before the dragon fruit tree blooms, the phosphorus content for dragon fruit should be increased. About 2-3 weeks after fruiting, topdressing should be done once. Only in this way can the fertilizer requirements of dragon fruit be fully met, 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 should mainly be fully decomposed farmyard manure, and the amount should be controlled according to the planting area. If the soil is relatively fertile, then less base fertilizer can be applied appropriately. Let the soil and fertilizer be fully mixed to improve soil fertility, promote the growth of seedlings after planting, improve the survival rate of seedlings, enhance growth vigor, and control the growth speed of seedlings. Only by ensuring sufficient nutrients can the normal growth of dragon fruit be guaranteed and your own planting benefits be expanded.
3. Topdressing
Before the dragon fruit tree has bloomed and fruited, the nutrient requirements of dragon fruit are relatively high, so topdressing at this time can promote the growth of dragon fruit branches. During the seedling stage, topdressing should mainly be liquid fertilizer or farmyard manure, and topdressing should mainly be applied more frequently but in small amounts. Then when new branches are found sprouting and turning green, topdress again. Dragon fruit needs topdressing about 5 times each year, generally at important growth periods such as the flowering stage, initial fruiting stage, and full fruiting stage. It should be noted that the annual fertilization amount should be appropriately higher than the previous year's fertilization.
4. Foliar fertilizer
Foliar fertilizer is mainly used to promote the growth of dragon fruit leaves. The stems and leaves of the dragon fruit tree are triangular columnar in shape, and when we spray foliar fertilizer, we should do it around this part to ensure comprehensive and even spraying. When spraying foliar fertilizer, mainly use microfertilizers, and adjust the nutrient ratio in the fertilizer according to the growth stage. For example, in the early fruiting stage, mainly use boron and magnesium, and in the later stage, mainly use calcium and iron. These elements can effectively improve the stress resistance of dragon fruit and improve fruit quality.
The spraying of foliar fertilizer has a more obvious effect than root fertilization, can allow nutrients to enter dragon fruit more quickly, and prevent nutrients from remaining in the soil. However, the duration of its effect is relatively short. Also, when applying foliar fertilizer, pay attention to the dosage, otherwise fertilizer damage is likely to occur. In addition, foliar fertilizer cannot be used as the main fertilization method, and can only assist fertilization, so as to ensure the growth of dragon fruit. That is all for today's introduction.
