This year is the result of the year of Yangmei. According to the current stage of Yangmeiyuan, the overall performance of this year's plum blossoms is: the flower arrangement of the early fruit stage and part of the fruiting period is more uniform, the tree is strong, and some of the fruiting period and most old trees have more inflorescences, and the growth potential Weak, therefore, we should do a good job in the following aspects: Fertilization of the year of Yangmeishu due to excessive flowering and excessive nutrient consumption, it is advisable to apply a top dressing in mid-March. The types of fertilizers are mainly quick-acting fertilizers. In the late April of Yangmei, the fruit can be traced to strong fertilizer, promote spring shoots and improve quality, promote fruit enlargement and early maturity. The fertilizer type is quick-acting fertilizer based on potassium fertilizer, and the general adult fruit tree can be Plant urea application 0 . 5 kg + 2 kg of potassium sulphate or 10 - 15 kg of ash . Flowering trees with more inflorescences can be sprayed with a thinning agent "sparse 5 " 50 times liquid or "sparse 6 " 100ppm liquid in the crown of the flowering period (the part where the number of flowering of the tree is small may not be sprayed), according to the test, the spray flower After the agent, the amount of flowering can reach 50 % - 60 %, the fruit shape increases by 34 % - 45 %, the maturity period is 4 days earlier , the quality fruit rate is increased by about 47 %, and the tree body nutrition is reduced due to thinning flowers. Excessive consumption, the result of the preparation of branches (spring, summer shoots) increased significantly, thereby increasing the annual output. However, when using the sparse agent, it should be noted that trees with less flowering in a small orchard, a single plant or a tree on a tree may not be sprayed. In addition, trees with densely grown canopy shoots and more resulting branches can be appropriately removed and short-cut partial branches before flowering to reduce the amount of results in this year (large year) and promote the extraction of the prepared branches. The annual output should be prepared, and the pest control of Yangmeiyuan should be strengthened, such as brown spot disease, prevention of cancer and pest control.
