Temperature regulation shield for controlling growth period of peach trees

Abstract

The invention discloses a temperature regulation shield for controlling a growth period of peach trees. The temperature regulation shield comprises an arc-shaped shield body and a support frame for supporting the shield body, and further comprises a temperature control device, wherein the shield body is provided with a through hole and a hole lid for opening or closing the through hole; a drip fogdispersal layer covers the side, which is close to the peach trees, of the inner side of the shield body; and a PET reflective film covers the outer side of the shield body. The temperature regulation shield has the characteristics of good insulating effect, a function of drip fog dispersal and capability of controlling the growth period of the peach trees. The temperature regulation shield is suitable for culture of the peach trees.

Description

technical field [0001] The invention belongs to the field of cultivation equipment for fruit trees, and in particular relates to a temperature regulating cover. Background technique [0002] Nowadays, in order to control the growth cycle of fruit trees, people often use greenhouses to achieve it; there are three types of greenhouse films currently used, one is a blow-molded polyolefin film, and its dripping and anti-fog function is realized by the internal addition method. With this structure, the heat preservation effect is poor, and the service life of dripping and defogging is 4-6 months, which cannot be synchronized with the service life of the shed film of 1-3 years; the other is the calendered PVC shed film, which also exists The thermal insulation effect is poor and the dripping and defogging function cannot be synchronized with the service life, and the physical and mechanical properties of these two types of shed films are low, and the phenomenon of shed tearing oft...

[0002] Nowadays, in order to control the growth cycle of fruit trees, people often use greenhouses to achieve it; there are three types of greenhouse films currently used, one is a blow-molded polyolefin film, and its dripping and anti-fog function is realized by the internal addition method. With this structure, the heat preservation effect is poor, and the service life of dripping and defogging is 4-6 months, which cannot be synchronized with the service life of the shed film of 1-3 years; the other is the calendered PVC shed film, which also exists The thermal insulation effect is poor and the dripping and defogging function cannot be synchronized with the service life, and the physical and mechanical properties of these two types of shed films are low, and the phenomenon of shed tearing often occurs during use; there is also a polyolefin woven cloth shed film, although this The shed film has high physical and mechanical properties and excellent wind resistance, but this kind of shed film has no dripping and defogging function, poor heat preservation ability, and limited use

[0003] In recent years, dripping anti-fogging agents have been applied on PE blown film lines, but limited to PE film products with high elongation, easy stretching, deformation, damage to the surface coating, and stress whitening that affect the use effect
