Four measures to control the growth and growth of bayberry trees

If the bayberry planted on the deep and fertile soil layer is allowed to grow naturally, the vegetative growth will be too prosperous, resulting in most of the nutrients of the tree being consumed by the growth of branches and leaves, resulting in little or difficult formation of flower buds, late fruiting or low yield. There are four measures to control the growing shoots of bayberry trees: 1. Control the amount of nitrogen fertilizer and appropriately increase the amount of phosphorus and potassium fertilizer. When fruit-picking fertilizer was applied from the end of June to the beginning of July, 10 kg of plant ash and 0.5 kg of calcium superphosphate or 1.5 kg of compound fertilizer could be applied per plant, combined with spraying 800-fold solution of new high-fat film to improve the utilization rate of effective components of fertilizer. two。 Root-breaking treatment. In late summer and early autumn, cutting roots in ditches with a depth of 30cm to 40cm near the crown dripping line can inhibit branch growth and promote fruit. at the same time, tree generals should be sprayed and sterilized in the whole garden to reduce the source of disease. 3. Ring cutting. The large branches were cut with thread in April (from the end of Xiehua to the first physiological drop). Huawang No. 2 was smeared to inhibit the growth of the main shoot, concentrate nutrients to supply the fruit to control the crown and promote the flower, improve the fruit expansion quality and prevent the fruit from falling. 4. Caohuawang 3 was sprayed on the crown from the first ten days of October to the middle of March of the following year, which promoted the nutrient reflux of the top tip and inhibited the growth of the main shoot.
