Technical Field

The invention belongs to the technical field of fruit and vegetable planting, and particularly relates to a method for planting grapes to resist fulguria.

Background

Grape fulgerizing is caused by physiological water imbalance, is a physiological disease, is not infected, is closely related to special climatic conditions and cultivation management conditions, and can be caused and serious if climatic conditions affecting water absorption, water loss and evaporation of grapes occur. The fulgerizing disease mainly damages young fruits, spike stalks and fruit ears of the grapes, and can occur from the young fruit period to the color transition period after the flowers of the grapes fall. Ears near the ground are easily damaged. The disease spots usually occur on the base of the fruit near the stem or the middle-upper part of the fruit surface, and can occur on the side and bottom of the fruit. In the early stage of the disease, the fruit grains lose water and are sunken, and become light brown small spots, and the later stage of the disease rapidly expands into large disease spots. In severe cases, 2-3 leaf spots appear on one fruit, and the whole fruit is dry. The lesions begin to be light brown, turn dark later, and gradually lose water to form dry scars, dry fruits and dry ears, sometimes the whole ear is dry.

The cause of the grape fulguration is directly related to the antioxidant properties of the fruit. Thus, irregular field operations may cause a reduction in fruit stress resistance, thereby causing physiological fruit moisture imbalance and ultimately causing or exacerbating the development of fulguration.

After fruit ripening and harvest, the incidence of scorching was calculated for the grapes in each test area and the results are shown in fig. 1. As shown in figure 1, the method disclosed by the invention can effectively prevent grape fulgering, reduce the incidence of grape fulgering and enhance the resistance of plants.

The technical solutions provided by the present invention are described in detail above, and for those skilled in the art, the ideas according to the embodiments of the present invention may be changed in the specific implementation manners and the application ranges, and in summary, the content of the present description should not be construed as limiting the present invention.
