Abstract

The invention belongs to the technical field of agricultural tool application, and particularly discloses a method for inhibiting grape powdery mildew by using reflective ground cloth, which comprises the following steps: (1) from the grape germination stage in the middle ten days of August, laying white reflective ground cloth with the width of 1 meter on each of grape planting ridges from grape plants to two sides; (2) in the grape flowering period in the first ten days of September, white reflective ground cloth with the width of 1 m is laid on the grape planting ridges from grape plants to the two sides for one time; (3) in the grape color changing period in the middle ten days of November, white reflective ground cloth with the width of 1 m is laid on the grape planting ridges from grape plants to the two sides, and the time period for laying the white reflective ground cloth is from the color changing period to the harvesting period. According to the method, the harm of powdery mildew can be relieved, pesticide use is reduced, the pesticide residue risk is reduced, and the purpose of preventing and controlling grape powdery mildew is expected to be achieved.

Description

【Technical field】 [0001] The invention belongs to the technical field of agricultural tool application, and in particular relates to a method for inhibiting grape powdery mildew by applying reflective ground cloth. 【Background technique】 [0002] Rain shelter cultivation is the main mode of viticulture in Guangxi. The rain shelter cultivation mode changed the meteorological factors of the grape plant canopy and provided suitable micro-meteorological conditions for the occurrence and prevalence of powdery mildew. Powdery mildew has become one of the main diseases of grapes in Guangxi. [0003] Grape powdery mildew is a fungal disease that occurs on grapes caused by the infection of Uncinula necator (Schw.) Burr., which mainly damages grape leaves, shoots and fruits. The main symptoms of the disease are that the surface of grape fruits and leaves is covered with white powdery mold, the grape leaves are withered, the fruits are cracked and dry, the taste becomes sour, and the...
