When will the dragon fruit be fertilized?

When will the dragon fruit be fertilized? What's the reason? Experienced netizens are also invited to help introduce that fertilization of dragon fruit is an important link in management, because the full play of fertilizer efficiency is related to soil and water, and only good soil structure and physical and chemical properties can promote microbial activities to accelerate nutrient decomposition and promote root absorption. The decomposition of fertilizer, absorption, operation, synthesis and utilization of nutrients must be carried out with the participation of water, so fertilization must be combined with irrigation and fertilizer effect will be brought into full play. In addition, fertilization is an important measure to maintain soil fertility and meet the nutrient elements needed for the growth and development of fruit trees. the type, quantity, method and period of fertilization will affect the effect of fertilization. Therefore, the fertilization of dragon fruit should be applied scientifically according to its nutritional characteristics and nutrition. Because the dragon fruit flowering period lasts for a long time, nutrition consumption is larger. Therefore, there is a great demand for fertilizer, especially in the high-yielding period, the management of fertilizer and water should be strengthened. The amount of fertilizer applied to dragon fruit is more scientific mainly from the consumption of the tree itself, the supply capacity of soil and the utilization rate of fertilizer; generally, the profit and loss of nutrition is judged by leaf nutrition analysis, and then adjusted by fertilization. The fertilizer of dragon fruit is mainly organic fertilizer, with a small amount of chemical fertilizer. In the part of farm manure, according to the proportion of chicken manure, pig manure and peanut bran at 1:2:7, the amount of use per mu is about 9 cubic meters per year (according to soil fertility and seedling growth). In addition, nitrogen fertilizer and potassium dihydrogen phosphate should be applied according to the need, and a small amount of fertilizer should be added in case of element deficiency. The results show that the application of fertilizer in the most suitable period can reduce the times of fertilization and improve the utilization rate of fertilizer. If it is a high-temperature and rainy area, applying thinly for many times can improve the utilization rate of fertilizer. Pitaya can be fertilized three times a year in July, October and March of the following year, with cow manure compost 1.2 kg / plant and compound fertilizer 200 g / plant respectively. Field experiments abroad show that the application of nitrogen fertilizer generally has a continuous effect on increasing yield, while the effect of phosphate fertilizer on increasing yield is shown in the first two years, and potash fertilizer and trace elements (B _ (·) _ (10), Cu _ (10) and Zn _ (mn)) have a better effect on the increase of yield in the later stage. The recommended amount of fertilizer for high-quality and high-yield cultivation of dragon fruit is 80 kg / ha of nitrogen in the first year, 20 kg / ha of phosphorus pentoxide in the second and third years, and 10 kg / ha of potassium oxide and 5 kg of boron / ha in the third year. Copper, zinc and molybdenum each 10 kg / ha. What are the pests of dragon fruit? What kind of environment is suitable for growing dragon fruit
