The key to cherry fertilization in autumn
In autumn, the roots of large cherry grow fast and the number of hair roots is large. The roots produced by fertilization in autumn are easy to heal and are beneficial to multiple roots. Fertilization can exert fertilizer effect in the same year, increase nutrient storage before wintering, improve the cold resistance of the tree in the next year, and increase the fruit. Quality and output. Therefore, we should pay attention to fertilization in autumn and lay a good foundation for high yield of cherries in the coming year. The large cherry garden is applied earlier in the autumn, generally starting from August to September.
Fertilization program:
1. Strip groove application is applicable to the application of base fertilizer. Ditching and fertilizing on the outer edges of the tree crown corresponding to the tree body. The grooves in one direction are used alternately every year. When the base is applied in autumn, the trench is dug, generally about 30 to 40 cm.
2. The annular groove is applied to the outer edge of the canopy to dig an annular groove. The depth and width of the groove are the same as those of the radial groove. This method is suitable for young trees with a small root distribution.
3. Spread the fertilizer evenly under the tree, then turn into the soil, about 20 cm deep. However, due to the shallow application, the root system is often floated and the root resistance is reduced. It should be carried out every other year with the radiation ditch.
4. Fertilization must be used together with photosynthetic nutrient film fertilizer, which can help plants absorb a large amount of light fertilizer, light energy, light, compatible with conventional fertilizers and nutrients to supply plant growth and development to the limit. One-year benefits for one application.
5. According to the tree's tree potential, the size of the tree, the amount of results, and the results of some soil testing formulas, some fruit tree compound fertilizers should be applied and the medium and trace elements should be supplemented in time.
