Simple building and covering method for vegetable steel frame greenhouse sunshade net

Abstract

The invention discloses a simple building and covering method for a vegetable steel frame greenhouse sunshade net. The method comprises the specific steps that a, the sunshade net is unfolded in the axial direction of a greenhouse, and one side of the sunshade net is pulled by a rope to the other side of the greenhouse along a top film of the greenhouse; b, the edge is fixed to a film rolling shaft through a film pressing clamp; c, the sunshade net is pulled to the other edge of the greenhouse along the top of the greenhouse, the rope is removed when the sunshade reaches the shoulder height of the greenhouse, and the edge of the other side of the sunshade is fixed to a film rolling shaft through a film pressing clamp; d, the sunshade net is folded through the film rolling shafts at the two ends of the sunshade net, the two film rolling devices are close to the greenhouse spine position of the vegetable steel frame greenhouse, and then a film pressing rope is used for the fixing the portion, located in the area, of the sunshade net to the corresponding greenhouse spine steel frame. The sunshade net is positioned to the corresponding greenhouse spine steel frame through the film pressing rope, and therefore shifting is prevented from being caused during covering and folding of the sunshade net in the using process; and the rope is used for pulling in the building process, so that manual climbing is avoided, and accidental injuries are reduced. The method is economical, practical and easy to popularize.

Description

technical field [0001] The invention relates to a simple method of building and covering sunshade nets for vegetable steel-frame greenhouses, especially a method for building and covering sunshade nets on vegetable steel-frame greenhouses, aiming at the problem of difficult growth of vegetables in high-temperature steel-frame greenhouses in summer, and belongs to special agricultural facilities technology field. Background technique [0002] High temperature and strong light in summer have adverse effects on vegetable planting, and the growth and development of greenhouse vegetables are seriously hindered, usually manifested as slow plant growth, poor flower bud differentiation, flower and fruit drop, sunburn disease, etc. in melon and fruit vegetables, which directly reduce vegetable quality and yield , Fast-growing leafy vegetables have problems such as difficult emergence and difficult growth, resulting in an imbalance in the supply of seasonal vegetables. The traditiona...
