Yang Meiwang grows trees to control four methods
Yangmei planted on deep, fertile plots of soil, if allowed to grow naturally, will have excessive vegetative growth, resulting in the consumption of tree nutrients mostly by the growth of the foliage, resulting in the formation of less flower buds or difficult to form, the tree enters the result of late Or low yield. How to prevent the occurrence of these phenomena? The following four methods are for reference. 1, control the amount of nitrogen fertilizer, appropriate application of phosphorus, potassium fertilizer dosage. When fruit fertilizer is applied at the end of June to early July, 10-15 kg of plant ash and 0.5 kg of superphosphate or 1-1.5 kg of compound fertilizer can be applied per plant. 2, cut off the root processing. In the late summer and early autumn, a 30-40 cm deep root cut near the canopy drip line can inhibit shoot growth and promote results. 3, ring cut. The large shoots were threaded (the cuts were cut without peeling) in April (from the end of the flower to the first physiological fruit drop). 4, platinol applied paclobutrazol. In early October-middle of March the following year, the big trees applied about 100 grams per plant and the small trees applied about 50 grams of paclobutrazol per plant. The method is to split the soil within the canopy (the depth of which is the degree of seeing the fine root), mix the paclobutrazol with a small amount of fine soil, and spread it evenly under the tree disk, covering the soil. After paclobutrazol is applied, it takes 4-5 years to apply it again for the second time.
