In recent years, Yangmei's planting efficiency in southern China's fruit production is unique, and it is a new and emerging small fruit pillar in our county. It occupies half of the income of the fruit farmers, but traditional cultivation methods and management measures have not been adapted to modern fruit requirements, especially the current positive It is Yangmei’s post-harvest season. It is also a weak link in traditional cultivation. The fruit growers must change their thinking and attach great importance to the work of pharmacy. In terms of simplicity, Yang Mei is asked to obtain high yields. Summer and autumn management can not be forgotten. The main technical measures are briefly described as follows:
(A) timely pruning: Yangmei rhizobial bacteria, from April to June coincides with the southern rainy season, Yangmei new shoots growth, easily lead to tree vigor, resulting in flower bud differentiation and nutritional accumulation. Therefore, for the initial result tree, the dense cross branches and parallel branches should be deleted from the base, and the dense branches at the upper part and the periphery of the crown should be based on the principles of “3 to 1, 5 to 2†and “strong stay inâ€. Sparse; mature results tree is mainly to eliminate the prosperous new shoots, retract the result branches, update the results of the branches.
(2) Reasonable fertilization: The results tree should be supplemented with phosphorus and potash after harvest. According to the tree vigor and the amount of results, each plant can revive 0.75-1 kilograms of potassium sulfate fertilizer and 0.5-0.75 kilograms of phosphate fertilizer on the outside of the canopy drip line or in the form of strips. Before the end of September, foliar dressing was conducted 2-4 times according to Yangmei's growth potential. The foliar fertilizer was dominated by potassium, phosphorus, and magnesium. The purpose of fertilization is to promote thickening of shoots, greening leaves, accelerating the aging of new shoots, and promoting flower bud differentiation.
(C) pest control: harm The main disease of bayberry is brown spot, insect pest is leaf roller moth, pine caterpillar. Dichotomous disease can be used to choose metalaxyl manganese zinc 800 times, M-45 1200 times the prevention and treatment. The leaf roller moth can be used as a 1000-fold solution of the acaricidal pine emulsion, and the caterpillar can be controlled with a 1200-fold solution of cypermethrin.
(D) root paclobutrazol: For Yangmei Wang long tree, after the fruit can be applied root paclobutrazol, usually 0.5-1 g per square meter projection tree, new shoots large amount of trees can increase the amount of root application, as appropriate.
