Shed frame capable of increasing quantity of illumination of vine crops on roof

Abstract

The invention relates to a shed frame capable of increasing the quantity of illumination of vine crops on the roof. The shed frame is composed of bearing legs, transverse beams, longitudinal beams, longitudinal rods, transverse rods and tie lines on joints, wherein the bearing legs, the transverse beams and the longitudinal beams are connected. When vines are led onto the frame, enough length needs to be reserved considering vertical displacement of the frame so that vine leaves cannot be damaged or broken. The bearing legs are connected with the transverse beams and the longitudinal beams, and the longitudinal rods, the transverse rods and the tie lines on the joints are arranged, so that when a shed needs to be lifted or lowered, the shed is just moved to corresponding buckles. When vines are led onto the frame at the first time, the vines need to be led to the highest position, so that when the shed is lowered later, the obliquely upward vines only need to be further bent; if the vines are fixed at a lower position at first, the vines cannot be lifted and the main vines may be pulled damaged or even pulled broken. In the morning when the sun rises in the east, main rods in the east are adjusted to be low; at noon from 11 o'clock to 14 o'clock, the main rods in the east are adjusted to be flush with main rods in the west; in the afternoon, the main rods in the west are adjusted to be lower; thus, the light receiving area is increased, the photosynthesis is enhanced, the photosynthetic yield is increased, and the yield of andromonoecious downy grapes on the shed frame can be improved by more than 18% compared with a common frame.

Description

technical field [0001] The invention belongs to the field of fruit and vegetable production, and in particular relates to a trellis capable of increasing the light quantity of roof vine crops. Background technique [0002] Due to population growth, per capita arable land is getting less and less. People think of using reinforced concrete flat roofs to plant vine crops. One is to increase agricultural products and the other is to improve the environment. Planting vines on the roof has its particularity, because its area and orientation are fixed. In this case, to improve the output and quality of vines, people have made many attempts, such as CN103650986A adjustable vegetable greenhouse, CN103907491A solar energy Coordinated ventilation cooling system for vegetable greenhouses, CN103891549A three-layer double-protected vegetable greenhouse, CN103891550A three-layer single-protected vegetable greenhouse, CN103891556A cooling device for vegetable greenhouses, CN103782843A labor...
