2. Fertilizer and water management is to ensure that fruit trees have sufficient nutrition. When planting Jiabao fruit trees, we must pay attention to the use of organic fertilizer, and use it together with microbial fertilizer and chemical fertilizer. When applying fertilizer, the ratio of nitrogen, phosphorus and potassium fertilizer should be kept at 1:2: 1. At the same time, it is necessary to analyze the nutritional components of fruit trees according to the growth of plants, supplement other elements at any time, and water more when planting, but prevent waterlogging. Pruning process is to ensure flower bud differentiation and fruiting rate. Because the growth process of Jiabao fruit trees is slow, when the fruit trees are flourishing, they can be pruned appropriately to ensure that the fruit trees absorb enough sunlight. When there are more branches with concentrated nutrients, the probability of flowering and fruiting can be increased. When pruning, cutting off redundant branches and diseased branches can reduce the nutrient consumption of fruit trees and help the trunk and root system to increase the accumulation and absorption of organic matter.
