When is the best time to fertilize dragon fruit? And what are the reasons? Experienced readers are asked to help explainFertilizing dragon fruit is an important part of management, because the full effect of fertilizer depends on soil and water; only a good soil structure and physical and chemical properties can promote microbial activity, accelerate nutrient decomposition, and promote root absorption.
The decomposition of fertilizer and the absorption, transport, synthesis and utilization of nutrients must take place with the participation of water, so fertilization must be combined with irrigation for the fertilizer effect to be fully exerted.
In addition, fertilization is an important measure for maintaining soil fertility and meeting the nutrient elements needed for fruit tree growth and development. The type, amount, method and timing of fertilization all affect the fertilization effect.
Therefore, dragon fruit should be fertilized scientifically according to its nutritional characteristics and nutrient status. Because dragon fruit has a long flowering period, nutrient consumption is relatively large. Therefore, the demand for fertilizer is relatively large, especially after entering the full production period, management of fertilizer and water should be strengthened even more.
The fertilization amount for dragon fruit is more scientific mainly when considered from the tree's own consumption, the soil's supply capacity and the fertilizer utilization rate; generally, leaf nutrient analysis is used to judge whether nutrients are deficient or excessive, and then fertilization is used to adjust it.
Dragon fruit fertilization is mainly based on organic fertilizer, supplemented with a small amount of chemical fertilizer. For the farmyard manure portion, according to the ratio of chicken manure, pig manure and peanut meal of 1:2:7, the application amount per mu is about 9 cubic meters/year (determined according to soil fertility and seedling growth), in addition, nitrogen fertilizer and potassium dihydrogen phosphate should be applied as needed, and when there is a nutrient deficiency, trace fertilizers should also be added in an appropriate amount. Experimental research results show that applying fertilizer at the most suitable time can reduce the number of fertilizations and improve fertilizer utilization rate.
If it is a high-temperature and rainy area, applying thin fertilizer multiple times can improve fertilizer utilization rate. Dragon fruit can be fertilized 3 times each year in July, October and March of the following year, each time applying 1.2 kg of cow manure compost per plant and 200 g of compound fertilizer per plant. Field trials abroad show that nitrogen fertilizer application generally has a continuous yield-increasing effect, the yield-increasing effect of phosphate fertilizer is shown in the first two years, and potassium fertilizer and trace elements (B, Cu, Zn, Mn) have a good effect on increasing yield in the later stage.
For high-quality and high-yield cultivation, the recommended fertilization amount for dragon fruit is 80 kg of nitrogen per hectare in the first year; 20 kg of phosphorus pentoxide per hectare each year in the second and third years; 10 kg of potassium oxide per hectare, 5 kg of boron per hectare, and 10 kg each of copper, zinc and molybdenum per hectare in the third year.
