Can dragon fruit use foliar fertilizer? First, understand the surface characteristics of dragon fruit plants. It belongs to the perennial vines of the cactus family and has the physiological and ecological characteristics of drought-adapted plants. Its stems and leaves have mutated, showing a triangular column of succulent green branches, and the leaves have been degenerated into acupuncture points, distributed on the triangular column edges. A large number of brown gas roots are produced on the surface of the branches, and the two constitute the whole vegetative organs of the dragon fruit to receive the foliar fertilizer. Foliar fertilizer is sprayed on the surface of the triangular column branches. In order to improve the efficiency of the fertilizer, the dragon fruit sprayed on the foliar fertilizer must be around the triangular column, and all three sides should be sprayed. Second, the surface characteristics of dragon fruit branching requirements for foliar fertilizer composition: the efficiency of foliar fertilizer is closely related to the surface traits and structure of the leaf. The cuticle of the epidermis is a barrier for mineral nutrients to enter the body, and the leaf surface is thick. The leaves do not easily penetrate into the leaves. After spraying, the liquid fertilizer drops down from the surface, causing nutrient loss without absorption and fertilizer. There is a thick and hydrophobic waxy layer on the surface of the dragon fruit triangle column, which puts special requirements on the preparation and application technology of the foliar fertilizer. In order to ensure the effect, it is necessary to add excellent additives in the preparation of foliar fertilizer. The auxiliary agent is an auxiliary component of the foliar fertilizer, and refers to an additive other than the nutrient element in the foliar fertilizer. The auxiliaries system of foliar fertilizer is more complicated and important, and it plays a decisive role in maintaining the excellent physical and chemical properties of foliar fertilizer and ensuring product quality. The main component of the auxiliary agent is a surface active substance, which has a series of effects such as infiltration, penetration, emulsification, dispersion, solubilization and moisturization. Generally, the addition of a small amount of surfactant can significantly reduce the surface tension of the fertilizer solution, which is especially important for fertilizer efficiency. Because the hydrophobic waxy layer on the surface of the dragon fruit column is thick, the water-soluble foliar fertilizer is not easy to infiltrate and permeate, which will directly affect the absorption of nutrients. Only the addition of excellent additives can make the foliar fertilizer adhere and spread on the surface of the triangular column, prolong the wetting time and achieve the purpose of nutrient absorption. Although there are many types of surfactants on the market, experimental studies at home and abroad have shown that the use of additives such as silicone and betaine is better. These are also suitable for the special foliar fertilizer of dragon fruit. The selection of nutrients for foliar fertilizers should be based on the supplement of medium and micronutrients, and the principle of combining with a large number of nutrients. In the long-term production period from April to November each year, the supply of magnesium, boron and nitrogen is the early stage. Lord, in the middle and late stages, more attention should be paid to the successive addition of potassium, nitrogen, magnesium, calcium, iron and boron. They are beneficial for improving the resistance and quality of dragon fruit. In addition, in order to improve the pertinence of foliar fertilization, it is also necessary to refer to the restricted nutrient types of the soil in which it is located. It is best not to choose Shiquanda rehydration, which is expensive and non-targeting, and the effect is not necessarily good. Third, the photosynthetic characteristics of dragon fruit have special requirements for the application of foliar fertilizer. The dragon fruit, which is succulent in arid areas, is a plant of the sedative acid metabolism type. Their stomata are open at night and closed during the day, and the opening and closing of the stomata is the opposite of other carbon type 4 plants. Because the main way of foliar nutrient nutrients entering the plant is through the pores and the fissures of the epidermal tissue, the best time for the spray effect of the dragon fruit leaf surface is after 5-6 pm, when the sun goes down, the fertilizer is beneficial to nutrient absorption. . In addition, in the foliar nutrient concentration, the characteristics of dragon fruit can be appropriately increased by 10% to 20%, and the effect is better. In short, the foliar spray effect is faster than the root fertilization, and can directly reach the dragon fruit vegetative body to avoid the fixation of fertilizer nutrients in the soil. But the disadvantage is that the amount of fertilizer is limited and the effect is relatively short. Therefore, foliar fertilization is an auxiliary method for fermenting dragon fruit. It can be used in conjunction with root fertilization to increase production. This article URL: Can dragon fruit use foliar fertilizer?
