Grape rain-preventing cultivation method

Abstract

The invention discloses a grape rain-preventing cultivation method. A rain shelter is arranged on grape planting rows. The rain shelter structurally is a horizontal shelter, an arc-shaped shelter or a steel frame arc-shaped shelter, and the shelter is covered with films. Upright columns used by the grape planting rows in the arc-shaped shelter are higher than upright columns on the two sides of the grape planting rows. The line space between the upright columns is 3.5-4.5 m, and the film covering time is from early February to early March every year; the line space between the grape planting rows of the horizontal shelter or the steel frame arc-shaped shelter is 1.5-1.8 m, upright columns are arranged on the grape planting rows, and the upright columns in the rows are connected through steel wires; the span of a shelter frame of the steel frame arc-shaped shelter is 10-12 m, and the shelter frame is covered with films; the film covering time of the horizontal shelter or the steel frame arc-shaped shelter is before January, the covering films are four layers, the whole shelter is covered with three layers of the covering films, one layer of the covering film is a mulch, and the covering films are combined with cultivation promoting. Diseases, pests and weeds are effectively avoided, early mature is promoted, quality of grapes is improved, the grapes can be sold in the market earlier and have a good sale, the price of the grapes is increased, and an effective method is provided for developing pollution-free agricultural products.

Description

technical field [0001] The invention relates to a rain-shelter cultivation method for grapes, which belongs to the technical field of grape planting. Background technique [0002] Grapes, also known as grapes, are a common plant of the genus Vitis. Deciduous vine with brown slender branches. Subcircular single leaves alternate, nearly entire to 3-7 lobed, with serrated margins. Leaf axils bearing compound buds. Tendrils or inflorescences opposite leaves. Hermaphrodite flowers; wild species often dioecious. 5 petals, connected at the top, separated from the base and receptacle in a cap-like shedding when blooming. The berries are mostly round or oval, with turquoise, purple black, purple red, etc., with fruit powder. [0003] Existing viticulture technology has serious pest and weed damage, poor fruit quality, late product launch, poor sales, low price, and excessive pesticide residues, which is not conducive to the development of pollution-free agricultural products. ...
