What kind of fertilizer should be applied to big cherry in spring

The main purpose at the beginning of spring is to fertilize big cherries, which is divided into two stages.

1. In the first stage, the pre-flowering fertilizer of cherries. The fertilizer here is mainly organic fertilizer, with emphasis on nitrogen fertilizer. According to the planting scale of cherry trees, we can prepare quantitative rotten and fermented pig, cow and sheep manure, plus urea, to dig trenches and apply deeply to the plants. The purpose of pre-anthesis fertilizer is to supplement tree nutrition in time and promote flower bud germination and spring shoot growth.

2. In the second stage, the postharvest fat of cherries. Post-flowering fertilizer is also called fruit fertilizer. Here we need to add nitrogen, potassium, phosphorus and boron to the fruit trees. Can be deep application of phosphorus potassium boron fertilizer, each tree common compound fertilizer plus boron fertilizer together. The effect of potassium sulfate balanced compound fertilizer is better, and the tender shoots are not flourishing. During foliar topdressing, the amino acid boron zinc calcium can be sprayed, or potassium dihydrogen phosphate (0.2%), boron fertilizer (0.1%) and brassinolide (50mg / L) can be sprayed and fertilized. The main purpose of post-anthesis fertilizer is to promote fruit development. Improve the quality and supplement the nutrition of fruit trees.

In a word, the big cherry needs to be fertilized twice in spring to ensure its timely supply of nutrients and promote the growth of fruit in the later stage.
