How to fertilize wax apple scientifically? A detailed guide to practical fertilization techniques
Wax apple, also known as Yangpu peach, purple pu peach, and water pu peach, is a nutritious fruit with certain medicinal and health-care value. To make wax apple produce more fruit, fertilization work must be done well, so how should wax apple be fertilized? Let's take a look at the detailed introduction.
1. Fertilizing young trees
For young wax apple trees, fertilization should follow the principle of frequent but light application, mainly with nitrogen and potassium fertilizers, to promote the start of growth in young trees. Never apply fertilizer heavily, as this can burn the roots, lead to poor root growth, and in severe cases cause the death of young trees. Generally, within half a year after planting, livestock manure and urine fertilizer at a concentration of 10%-15% should be applied once a month, which can promote the growth of new roots and new shoots in young trees. After that, fertilize once every 1-2 months, generally before new shoots emerge, to provide sufficient nutrients for new shoot growth.
2. Topdressing in stages
Wax apple has a relatively high fertilizer demand. In the early stage, more phosphorus and potassium fertilizers should be applied. During flower bud differentiation, attention should be paid to the application rate of nitrogen fertilizer. If nitrogen fertilizer is applied excessively, it will cause vigorous growth and excessive vegetative growth. After the fruit expands, heavy application of phosphorus and potassium fertilizers should be made to promote fruit development and improve yield and quality. Generally, before flowering, nitrogen, phosphorus, and potassium should each account for 50% of the total fertilization amount. During the flowering and fruiting stage, the remaining nitrogen fertilizer and 25% of the phosphorus and potassium fertilizers should be applied. During the harvest stage, the remaining 25% of the phosphorus and potassium fertilizers should be applied.
3. Foliar spraying
When there are many fruiting trees, the nutrients absorbed by the root system cannot meet the growth and development needs of the fruit. At this time, foliar spraying can be used to maintain the plant's nitrogen, phosphorus, and trace elements. In addition, when planting in coastal areas, the soil salinity is relatively high, so fresh water should be introduced to wash away salt, reduce the soil's salt content, improve soil structure, and allow the plants to grow normally.
4. Precautions
After flower induction in wax apple, attention should be paid to nutrient supply. During the flowering stage, attention should be paid to nitrogen fertilizer supply. During the flowering stage, attention should be paid to the ratio of phosphorus and potassium fertilizers and the supply of trace elements to avoid nutrient deficiency in the plant. During the fruit-setting stage, high-potassium fertilizer should be supplied, and foliar fertilizer should be added to supplement trace elements that may be lacking, so as to ensure the nutrient demand for flowering and fruiting. During the flowering and fruiting stage, attention should be paid to the application of nitrogen fertilizer. Many fruit growers apply too much nitrogen fertilizer in order to increase production, which causes vigorous growth of branches and leaves, competes with the fruit for nutrients, leads to poor fruit quality, and produces the opposite effect.
