How to properly fertilize citrus
source: time: 2020-01-04
Citrus is an evergreen fruit tree with a long annual growth period and large nutrient consumption. It has its special law of fertilizer requirement. Only reasonable fertilization can enhance tree vigor and resistance, and achieve the purpose of high quality, high yield and stable yield.
1. Reasonable application of organic fertilizer and inorganic fertilizer
If long-term single application of chemical fertilizers in the orchard will acidify the soil, reduce fertilizer retention and fertilizer supply capacity, it is not conducive to soil improvement and fertilization, and it is not conducive to the sustainable development of the citrus industry. Therefore, the rational combination of organic and inorganic fertilizers should be adhered to to improve the physical and chemical properties of the soil, increase the soil's ability to retain and supply fertilizer, and increase the utilization of nutrients.
2. Determine the suitable period of fertilization based on various factors
According to the soil fertility status and the nutrient requirements of each stage of citrus growth and development, fertilizers should be applied in a timely, appropriate amount and scientifically. In addition, the key period of fertilization should be determined according to the type and nature of fertilizer. If chemical fertilizers are the mainstay, summer fertilizers should be reapplied; organic late-acting fertilizers should be used as soil, and the application of overwintering fertilizers should be paid attention to.
3. Pay attention to fertilization methods to improve fertilizer utilization
The depth of fertilization should be determined according to the depth of root distribution. Generally speaking, the base fertilizer should be applied deeply, and the topdressing should be applied shallowly during the growth period.
