Bagging method for dwarfing baiyu loquat in river beach areas

Abstract

The invention provides a bagging method for dwarfing baiyu loquat in river beach areas. The method comprises the steps that 1, rootstock treatment is conducted; 2, baiyu loquat branch treatment is conducted; 3, branch grafting is conducted; 4, after branch grafting is completed for one month, when grafting buds sprout, sprouts on the rootstock are removed, when choking happens at the grafting part of a branch and the rootstock, binding or wax sealing is removed, after branch grafting survival is achieved, water and fertilizer are applied each month to promote seedlings to grow, and seedling emergence can be achieved after 7-10 months; 5, fruit thinning is conducted; 6, bagging is conducted. By means of the bagging method for dwarfing the baiyu loquat in the river beach areas, the problems that a loquat crown is too high and over crowded, management is inconvenient, fruiting part is limited on the periphery, flowers and fruit are prone to freezing injury and sunburn, and the economic yield is low can be effectively solved, the work efficiency is obviously improved, and the production cost is obviously reduced. Meanwhile, bagging of loquat fruit has the effects of preventing fruit cracking and the fruit injury caused by machinery and relieving frost damage, rusty stain of the fruits, sun burn, red spot diseases and damage caused by insects and birds can be reduced, pesticide spraying is reduced, and the commercial value of the loquat is improved.

Description

technical field [0001] The invention designs a bagging method for dwarfing white jade loquats in river beaches. Background technique [0002] White jade loquat was originally produced in Baisha Village, Dongting, Dongting, Wuxian County, Jiangsu Province (now Wuzhong District, Suzhou City). In the early 20th century, it was selected by Tang Yongshun, a farmer in the village, from Shisheng Zaohuang Baisha. "Zaohuang", and then in the early 1960s, an excellent single plant was selected for the Horticulture Department of Jiangsu Academy of Agricultural Sciences, code-named "635". In the late 1970s, the Wu County Fruit Tree Research Institute observed and studied this for many years, and believed that this variety and Zaohuangbaisha had different fruit shape, size, pulp thickness, seed number, size, shape and color, petal shape, leaf shape and drought resistance. traits are different. According to the cultivation area, yield and variety characteristics, it is named Baiyu loqua...

Problems solved by technology

[0003] However, because the canopy of the white jade loquat tree is too high and dense, it is inconvenient to manage, and the fruiting parts are limited to the periphery, and the flowers and fruits are vulnerable to freezing damage and sunburn, resulting in low economic output.

At the same time, because loquat fruit is exposed to the air, the flower and fruit are vulnerable to freezing damage and sunburn, and rust spots, sunburn and red spot will appear on the fruit surface. For this, the usual treatment method at this stage is to spray pesticides on the fruit surface. In line with the concept of green fruits and vegetables, affect the commodity value of white jade loquat
