It is advisable to use no less than 3-4 times a year, and several periods of use are recommended:
1. Before flowering
During the flowering and fruit setting period, a large amount of nutrients are consumed. Insufficient nutrients are easy to drop flowers and buds. During the flowering period, it is generally not recommended to water more, and it is easy to cause poor fruit setting. Therefore, we need to supplement nutrients before flowering to allow the crops to spend the entire flowering period. Supplement high-phosphorus water-soluble fertilizer and mineral potassium fulvic acid before.
2. Young fruit expansion stage:
The reason is the same as above, the expansion period of young fruit is a period of rapid cell division, which requires a lot of nutrients. We use balanced macroelements, and we also need to use mineral potassium fulvic acid.
3. After bagging fruit trees, before continuous high temperature in summer:
The use of mineral potassium fulvic acid during this time period is to allow potassium fulvic acid to continuously chelate and supply nutrients to crops and continue to expand in the bag. There is another important reason: drought resistance! The mineral source potassium fulvic acid flocculates in the soil, It becomes a cementing agent, combines with soil particles to form soil complexes such as humates, and becomes a water-stable aggregate structure, thereby greatly improving soil permeability and anaerobicity, oxidation and reduction, water permeability and water retention, fertilizer supply and fertilizer retention. It improves the water, fertilizer, gas and heat conditions of the soil; greatly improves the availability of soil nutrients, forming a small reservoir and a small fertilizer reservoir to cope with the continuous high temperature and drought in summer.
4. Before coloring:
The leaves, branches and roots of the crops are already exhausted when they enter the color-changing stage: aging, yellowing, and serious degradation. In particular, the absorption capacity of the root system is reduced, and at this time, the coloring of the fruit requires a lot of nutrients, not only to supply the fruit, but also to supply the flower buds. The long-lasting effect prevents de-fertilization in the later stage and avoids de-fertilization such as turning green and soft grains.
