Fertilization of cherry in autumn is the most important.

The root system of cherry grows fast and has a large number of roots in autumn. the broken 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 the nutrient reserve before overwintering, and improve the cold resistance of the tree in the following year. increase fruit quality and yield. Therefore, attention should be paid to fertilization in autumn to lay a good foundation for high yield of cherries in the coming year. The application of base fertilizer in big cherry orchard is early in autumn, which usually begins from August to September.

Fertilization scheme:

1. Strip ditch application is suitable for base fertilizer application. Ditch and fertilize the outer edge of the crown corresponding to the tree body. The trenches in one direction are used alternately every year. When base fertilizer is applied in autumn, the trench is larger, generally about 30cm to 40cm.

two。 The ring ditch is applied to dig a ring ditch around the crown, and the depth and width of the ditch is the same as that of the radial trench. This method is mostly suitable for young trees with small root distribution.

3. Spread the fertilizer evenly under the tree and turn it into the soil at a depth of about 20 centimeters. However, the shallow application often leads to the floating of the root system and reduces the root resistance, which should be carried out every other year with the radiation ditch application method.

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 conventional fertilizers and nutrients to the limit of plant growth and development. One application is beneficial for the whole year.

5. The application of base fertilizer in autumn should apply some fruit tree compound fertilizer according to the tree potential, tree size, fruit amount, and the results of some soil testing formula, and supplement the trace elements in time.
