Reusable fruit and vegetable seedling stage protection device

Abstract

The invention discloses a reusable fruit and vegetable seedling stage protection device which comprises a cone frustum-shaped protection cover body, the protection cover body is transparent and is made of polyethylene added with dripping functional master batch, light receiving convex edges are evenly arranged on the protection cover body, a heat dissipation hole is formed in the leeward face of the protection cover body, and the heat dissipation hole is communicated with the protection cover body. A fixed water absorption ring is arranged at the bottom end of the protective cover body in the circumferential direction of the protective cover body, and a plurality of cross-shaped fixed water absorption holes are formed in the fixed water absorption ring. The protection device is only arranged for a single fruit and vegetable seedling, so that the situation that the whole seedling is infected by insect pests or diseases of one seedling is effectively prevented; the protective cover body is of a three-dimensional structure and can be installed and fixed only by inserting a fixing rod into the fixing and water collecting hole, installation is easy and convenient, and operation can be completed by one person. In addition, the protective cover body is low in manufacturing material, low in manufacturing cost and capable of being repeatedly used, the light receiving protruding edges for increasing the light receiving area are further arranged, light transmission is high, taper arrangement is achieved, and the water collecting performance is good.

Description

technical field [0001] The invention relates to a protective device for fruit and vegetable seedling stage, in particular to a reusable protective device for fruit and vegetable seedling stage. Background technique [0002] Due to the cold wind and low temperature in winter and spring, when planting fruit and vegetable seedlings with a density of less than 500 plants / mu earlier in winter or spring, such as bitter gourd, loofah, wax gourd, pumpkin, banana, passion fruit, etc. The arch shed film is used for windproof and thermal protection of the entire row or single plant. In addition, in summer and autumn in the south, affected by severe weather such as typhoons and heavy rainfall, it is inconvenient to use small arch sheds for protection during the open-air planting of fruit and vegetable seedlings due to factors such as high temperature and cost. There are certain difficulties in reuse, resulting in environmental pollution. [0003] At present, most of the production use...

AI Technical Summary

Problems solved by technology

The protection device of this structure has the following defects: First, at least three people are required to install the small arch shed, and it needs to be covered with soil, the installation procedure is complicated and troublesome, the workload is large, time-consuming and labor-intensive, the efficiency is extremely low, and the installation and use cost is high 2. For ventilation, the protective film needs to be punched. In addition, due to fixing with soil and polluting the film, the protective film is mostly disposable and cannot be reused. It is thrown away after use, which not only pollutes the environment but also increases The cost, plus the protective film needs multiple supports to support and fix, and the labor cost is more; third, the evaporation of soil moisture in the small shed tends to form water droplets on the protective film against the ground, thereby reducing the light transmittance of the protective film, which in turn affects the growth of fruit and vegetable seedlings

In addition, when water drops onto the plants, it is easy to cause the plants to be susceptible to diseases; Fourth, the entire small shed is covered with many fruit and vegetable seedlings. When a certain seedling has insect pests or is susceptible to disease, it is easy to infect and spread to the seedlings in the entire protective film. Increased pest control costs
