Novel main and sub arch single body steel frame greenhouse

Abstract

The invention discloses a novel main and sub arch single body steel frame greenhouse, which comprises a wall base. The installation of a main arch and a sub arch is more stable and firmer; the main arch achieves the major support effect; the sub arch achieves a minor support effect; a longitudinal pull rod connects the main arch and the sub arch for forming a whole; a wind-proof clamp groove is a fixed film; a manual film winding device has the effect of opening and closing an adopted ventilation opening; an insect prevention net is a net additionally arranged at the ventilation opening; a film is a covering layer and achieves the heat insulation effect; the end parts of the greenhouse are two end parts of the greenhouse body, and the like. The novel main and sub arch single body steel frame greenhouse sufficiently overcomes the defects that a sunlight greenhouse is unfavorable for summer and autumn planting, and the single body greenhouse cannot realize overwintering culture. The greenhouse body adopts a main and sub arch steel structure and adopts double-layer coverage for heat insulation, the lowest temperature in winter reaches 10 DEG C, the greenhouse is suitable for hanging tendril crop planting, the space in the greenhouse is large, the ventilation is good, the crop yield is high, the land utilization rate is high, the repair cost is low, the material reutilization rate is high, the cost is low, and the greenhouse belongs to an ideal plastic greenhouse for facility culture.

Description

technical field [0001] The invention discloses a solar greenhouse in crop planting technology, in particular to a novel main and auxiliary arch single steel frame greenhouse. Background technique [0002] The current greenhouses are all single sheds, which cannot be cultivated over the winter. Insufficient sunlight in winter, high nitrate content in crops, long-term consumption will cause poisoning, and insufficient photosynthesis. The content of chlorophyll, vitamin C, and sugar in crops is insufficient, and the ventilation in the greenhouse is not good. The evaporation of water on the surface of the middle leaves decreases, and the corresponding mineral elements absorbed from the soil also decrease, which makes the mineral nutrient content of the crops insufficient. The planting temperature in summer and autumn is high, which is not conducive to the degradation of pesticides and easily causes pesticide residues. Contents of the invention [0003] In order to overcome the...
