Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of watermelon grafting, especially to a protection clamp for preventing high-temperature and humidity infection of a watermelon grafting seedling interface in a hot region. BACKGROUND

[0002] In the tropics and subtropics (hereinafter referred to as "hot region"), grafting seedling technology is often used to improve the disease resistance and stress resistance of watermelon plants during cultivation. The healing quality of the grafting interface directly determines the success rate of seedling cultivation. However, the hot region is characterized by high temperature (daytime temperature often reaches 30-40°C) and high humidity (air relative humidity is usually above 75%), which easily leads to bacterial and fungal growth at the interface, causing infection and rot, and significantly reducing the survival rate of grafting.

[0003] Currently, a protection clamp is used to hold the top of the stock stem after watermelon grafting, so that the bottom of the inserted watermelon scion is tightly attached to the stock. However, the existing watermelon grafting seedling protection clamp is usually a single plastic clamp structure, which can only achieve the function of fixing the interface. In a high-temperature environment, the clamp body is tightly attached to the stem, which easily forms a local hot area, and the moisture is difficult to discharge, providing conditions for the reproduction of pathogenic bacteria, which easily leads to high-temperature and humidity infection. Moreover, the weight of the protection clamp after clamping is completely supported by the stem, which easily leads to bending of the stem and affects the recovery of the interface.
