Cherry differs from other fruit trees in that its flower bud differentiation time is earlier. Generally after the fruit is picked, the tree enters the flower bud differentiation stage. In order to promote the differentiation of flower buds and ensure the nutrient supply of the tree, the fruit grower must continuously perform the foliar dressing after the end of the cherry picking, and timely apply the high-quality basal fertilizer within 40 days, and must not wait until the fall to “countâ€.
In the application of basal fertilizers, organic fertilizers are mainly used. The amount of fertilizer can be determined according to the age of the trees, the size of the tree crown, the yield and the tree vigor. Generally, 50-75 kg of organic fertilizer is applied to each cherry. In order to promote flower bud differentiation, we must also pay attention to increasing phosphorus, potassium fertilizer and trace element fertilizer.
When basal fertilizer is applied, part of the root system must be renewed in conjunction with soil deep turning to promote new roots and increase nutrient accumulation in the tree to meet the needs of flower bud differentiation for nutrition.
