Foliar Fertilizer Technology of Dragon Fruit

Fire dragon fruit is deeply loved by many consumers because it tastes sweet and not greasy. As we all know, dragon fruit likes to grow in a warm and sunny environment. It is a tropical fruit. So how to apply foliar fertilizer to grow dragon fruit? Let's study together.

Foliar Fertilizer Technology of Dragon Fruit

1. Concentration dilution, fertilizer concentration dilution calculation requirements are strict, reasonable concentration can greatly supplement nutrients, the concentration is too high or too low can not achieve the desired effect.

2. The selection of sprayer, high pressure and good atomization can greatly improve the foliar absorptivity.

3. spraying method, when spraying, the sprinkler should be tilted upward, facing the back of the dragon fruit leaves and the fruit surface, which can promote the rapid absorption, transformation and utilization of nutrients.

How to improve the utilization rate of foliar fertilization

The main results are as follows: 1. To understand the growth characteristics of dragon fruit, the dragon fruit plant belongs to perennial vine of cactus family, which has the physiological and ecological characteristics of drought adaptive plant. Its stems and leaves have changed, showing triangular column-shaped succulent green branches, while the leaves have been degenerated into needling spots, distributed on triangular prisms. There are a large number of brown aerial roots on the branch surface, which constitute all the vegetative organs for dragon fruit to receive foliar fertilizer.

2. The requirements for the preparation of foliar fertilizer composition according to the branch surface characteristics of dragon fruit the efficiency of foliar fertilizer has a great relationship with the leaf surface character and structure. The cuticular layer of epidermis is a barrier for the entry of mineral nutrients into the body. The thick leaf surface is not easy for fertilizer droplets to infiltrate into the leaves. After spraying, liquid fertilizer droplets will slip down from the surface, resulting in nutrient loss without absorption and fertilizer effect. There is a thick, hard and hydrophobic wax layer on the surface of the triangular column of dragon fruit, which puts forward special requirements for the preparation and application of foliar fertilizer. In order to improve the fertilizer utilization efficiency, instantaneous treatment and fission can be added after the foliar fertilizer is diluted to make the crops absorb instantly.

3. The selection of nutrient composition of Huolongguo foliar fertilizer should be based on the principle of supplement of medium and micronutrient elements and combination of a large number of nutrient elements. in the long production period from April to November every year, magnesium, boron and nitrogen were mainly supplied in the early stage. as a result, more attention should be paid to the successive supplements of potassium, nitrogen, magnesium, calcium, iron and boron in the middle and later stages. They are beneficial to improve the stress resistance and quality of dragon fruit.

4. According to the characteristics of pitaya, pitaya is originally produced in arid areas with succulent characteristics, which belongs to the type of acid metabolism of sedum. Their stomata are open at night and closed during the day, which is contrary to that of other C4 plants. As the main way for foliar fertilizer to enter the plant is through stomata and cracks in epidermis, the best time for foliar fertilizer spraying of dragon fruit is after 6 o'clock in the afternoon. Spraying fertilizer at sunset is beneficial to nutrient absorption.

Matters needing attention in foliar fertilization of dragon fruit

The main results are as follows: 1. formula, there is a great demand for potassium in the later stage of pitaya fruit, so foliar fertilizer must contain this element, and other trace elements mentioned in the above paragraph should have it. Secondly, the current high-end foliar fertilizer contains appropriate humic acid and amino acid components, which is of great help to the comprehensive supplement of pitaya fruit nutrients.

2, water-soluble, foliar fertilizer requires that water-soluble must pass, there is no impurity precipitation after dissolution, so that the pipe will not be blocked, this can be referred to Liheng fruit tree foliar fertilizer, in which nutrients and water solubility are up to the standard, and does not contain hormone components.

Treatment of yellowing of dragon fruit leaves

1. Spray the branches. Serious fruit trees can be sprayed with 0.3-0.5% ferrous sulfate solution, or 0.5 jin of copper sulfate, 1.25 jin of quicklime and 160 jin of water before germination, which can control the occurrence of the disease.

2. Trunk injection. The most commonly used and effective solution is 0.05-0.1% ferrous sulfate. Injection with 0.05-0.1% ferric citrate solution also has a certain effect.

3. The application of metal chelate iron. Chelating metal is formed by adding metal ion to chelating agent. The application of chelated iron can improve the supply of some nutrient elements in the soil. In addition to soil application, chelated iron can also spray 0.1-0.2% integrated iron solution on the leaf surface to restore the leaf color.

4. Soil application or foliar spraying should be careful not to be excessive, so as to avoid drug damage.

It turns out that there are so many techniques for foliar fertilization of dragon fruit, have you all learned it? To know that foliar fertilization is a key step, related to the rising trend of dragon fruit in the later stage, I believe that as long as the painstaking efforts, there will be something in return. I hope the above article will be helpful to all of you.
