''W''-shaped greenhouse

Abstract

The invention relates to a ''W''-shaped greenhouse. The ''W''-shaped greenhouse comprises four upright pillars, wherein two upright pillars form a right support, and the other two upright pillars forma left support, the two upright pillars forming the right support are adjacent upright pillars, and the two upright pillars forming the left support are adjacent upright pillars; each two adjacent upright pillars are connected through an upper connecting rope and a lower connecting rope, the two upper connecting ropes are connected through an upper transverse connecting rope, the two lower connecting ropes are connected through a lower transverse connecting rope, the upper connecting ropes and the lower connecting ropes are horizontal with each other, and the upper transverse connecting ropeand the lower transverse connecting rope are horizontal with each other; and a film sequentially passes through the upper transverse connecting rope and the lower transverse connecting rope. The ''W''-shaped greenhouse provided by the invention has a small-unit water storage function, and soil is not directly flushed with rainwater, so that the water and soil loss phenomena are reduced; the ''W''-shaped greenhouse is suitable for planting fruit trees sand forests, meanwhile, the input of the unit area of the greenhouse can be greatly reduced, and the large-area popularization of farmlands is facilitated; and the ''W''-shaped greenhouse is combined with a fly net, so that the dosage of a drug for preventing pests and treating diseases can be decreased.

Description

technical field [0001] The invention belongs to the field of agricultural equipment and relates to a "W-shaped" greenhouse. Background technique [0002] At present, there are relatively large risks in farmland planting in our country. In the case of frequent extreme weather, it has caused huge losses to growers. In order to encourage growers to expand their planting area, the government invests huge sums of money every year to renovate farmland facilities. Little effect has been achieved, mainly because the following problems have not been solved. The demand for rainwater by the first crops cannot be controlled, which is equivalent to relying on the weather. By increasing storage facilities, the problem cannot be solved fundamentally, and disputes will also arise due to water distribution issues; Second, soil erosion is serious in slope fields in most areas of my country, the living soil layer is reduced, and the fertility is reduced.

Problems solved by technology

[0002] At present, there are relatively large risks in farmland planting in our country. In the case of frequent extreme weather, it has caused huge losses to growers. In order to encourage growers to expand their planting area, the government invests huge sums of money every year to renovate farmland facilities. Little effect has been achieved, mainly because the following problems have not been solved. The demand for rainwater by the first crops cannot be controlled, which is equivalent to relying on the weather. By increasing storage facilities, the problem cannot be solved fundamentally, and disputes will also arise due to water distribution issues; Second, soil erosion is serious in slope fields in most areas of my country, the living soil layer is reduced, and the fertility is reduced. Planters increase the amount of fertilizer, which not only increases the cost of planting, but also aggravates soil compaction; third, excessive rainfall will cause severe waterlogging, resulting in The reduction in production and income is basically insurmountable

[0003] In order to solve the problem of out-of-season planting, the government has promoted greenhouse planting technology, but the existing greenhouses have particularly high requirements on water sources and topography, and most farmlands are not suitable for them. If the reservoir is rebuilt, the ecological environment will be affected; The cost of greenhouses is high, and farmers cannot afford it economically; the height of greenhouses is limited, and it is difficult to plant economic trees in greenhouses
