Because the base fertilizer plays a smooth and slow effect, when the cherry tree needs to increase the fertilizer amount, it must be replenished in time to meet the nutrient needs of the fruit tree growth and development. Therefore, topdressing plays the key to increasing production and income, but when is cherries topdressing? What is the amount of topdressing? The following farming tips will introduce you one by one. First, the time of cherry tree topdressing Cherry trees need to be topdressed three times a year, generally divided into flowering fruit, late fruit harvesting and autumn. 1. Cherry blossom fruit top dressing: This top dressing is generally best after the cherry tree Xiehua, before the fruit core and embryo development. The top dressing is to increase the fruit setting rate of the cherry and the nutrients needed for the development of the fruit and the growth of the leaf, and also to promote the increase of the fruit. The top dressing is mainly based on quick-acting nitrogen fertilizer, with appropriate amount of phosphorus and potassium fertilizer. Cultivation (help reminder: this time the topdressing can not be too late, too late will make the fruit mature late, and will cause nutrient deficiency and fruit drop phenomenon.) 2. After the fruit picking of the cherry, the topdressing is carried out after the fruit is harvested. This stage is the stage of the nutrient consumption of the cherry tree from the shoot tip, flowering fruit setting and fruit development, and the transition to the long-term accumulation stage of nutrition. And began to concentrate on flower buds. At this time, timely supplementation of fertilizers, play an important role in the nutrient accumulation of cherry trees, promote flower bud differentiation, and maintain a strong tree. The top dressing mainly uses organic fertilizer, farmyard manure and balanced compound fertilizer. 3, cherry tree autumn top dressing: this top dressing can be combined with autumn base fertilizer, the role is to improve the late cherry tree nutrient accumulation, enhance wintering cold resistance, laying the foundation for the second year of high yield and quality. The fertilizer used in this top dressing is mainly based on nitrogen fertilizer, combined with phosphorus and potassium fertilizer, and applied together with the base fertilizer. Second, the amount of fertilizer used for cherry tree topdressing The amount of fertilizer used for topdressing of cherry trees is generally adult trees. The amount of topdressing per plant in the flowering period is 1~2 kg of compound fertilizer, and the amount of topdressing after harvest is 1~1.5 kg per compound fertilizer. The initial results of cherry trees are topdressed at each stage. 0.5 kg of diammonium phosphate was applied per plant. Third, cherry tree topdressing method When the cherry tree is compounded with fertilizer, it is used to open the spray or curved groove 30 cm away from the canopy. If the ditch is used, several more should be opened to enlarge the fertilization surface, which is convenient for the cherry tree root to absorb and prevent root burning. occur.
