Method for rain sheltering, sun shading and bird prevention during sweet cherry plantation in warm southern regions

Abstract

The invention relates to a method for rain sheltering, sun shading and bird prevention during sweet cherry plantation in warm southern regions. Pergolas used in the method are usually cement columns arranged in rows that are at intervals in the longitudinal direction; lower parts of the cement columns are buried in the ground; surrounding pull-down strings of the columns are fixed via ground anchors; a steel tube is placed on the cement columns in each row; an arch with two downward bent ends is placed on each two longitudinal cement columns, to form a top frame; the two ends of the bent tube are located on steel tubes of pergola shoulders; longitudinal double-pull rods are connected and fixed; plastic films are longitudinally laid on the pergola frame to cover the whole pergola frame; film pressing wires outside the films are fixed on steel strands on both sides and the arches; two longitudinal sides of the plastic films are connected to winding bars; the winding bars are connected to a film winding device; the film winding device winds the plastic films around the winding bars; the plastic films can be wound with the winding bars to the 1/2 position of the pergola frame; and the degree to which the plastic films are folded or unfolded on the pergola frame is controlled by the film winding device. According to the present invention, a single pergola play a comprehensive role of rain sheltering, sun shading and bird prevention, thereby greatly reducing facility costs and labors.

Description

technical field [0001] The invention relates to a management method for planting sweet cherries in southern warm regions. Background technique [0002] Cherry is a plant of the subgenus Prunus in the family Rosaceae (Rosaceae). The types of cherries cultivated as fruit trees in the world include European sweet cherry, European sour cherry, Chinese cherry and prunus cherry. The cherries cultivated commercially in my country are mainly sweet cherries (Prunus avium L.) and Chinese cherries (Cerasus pseudocerasus). The so-called sweet cherries usually refer to European sweet cherries, also known as big cherries, commonly known as cherries, which are the main direction of the development of cherries at present and in the future. The fruit of sweet cherry is bright in color, crystal clear and beautiful, red like agate, yellow like condensed fat, and sweet in taste. The fruit is rich in sugar, protein, vitamins, calcium, iron, phosphorus, potassium and other elements, especially i...

Problems solved by technology

[0005] In the warm regions of the south, the rain and heat in the warm regions of the south are in the same season, and the rainfall far exceeds the needs of cherries. Especially in May and June, the high temperature, high humidity and excessive rainfall not only cause cracking of sweet cherries in the mature stage, but also the flower bud differentiation period after fruit picking. High temperature and high humidity cause the tree body to grow excessively, which reduces the nutrients that can be used for flower bud differentiation. Insufficient flower bud differentiation will directly affect the next year's yield
