The advantage of the glutinous rice paper grafting belt is that the bud point can break through the grafting belt by itself, and the subsequent grafting belt can slowly age and degrade under the irradiation of ultraviolet rays. However, the rainproof effect is not superior to that of ordinary plastic film, cling film and plastic grafting. When we graft the rose or fruit tree with the glutinous rice paper grafting belt, the bud point can be completely wrapped in it, and the bud point can break through the grafting belt without paying attention to it later, but the ordinary plastic grafting belt needs to expose the bud point and need to do so by itself in the later stage.

The tree-shaped Chinese rose I grafted below, the bud point can break through the grafting zone by itself.

Generally speaking, when Chinese rose or fruit trees are grafted in spring, there is relatively little rain, and it is often only light rain. Generally, there is no heavy rain for 7-1 days after grafting. No matter whether it is a sticky rice paper grafting belt or a common grafting belt, it is not necessary to deliberately prevent rain. According to my own experience in grafting Chinese rose, the healing time of the grafting joint is usually 7-1 days. If there is heavy rain during this period, Rain will enter the marriage interface along the gap between the grafting belt and the trunk, which will lead to the infection of the marriage interface becoming black. If the grafting has been half a month later, the marriage interface has basically merged. At this time, even if it encounters heavy rainfall, there is no need to worry.

when tying the grafting belt, it is generally wound up from the bottom, so that the grafting belt is the upper layer pressing the lower layer. Like tiles, even if there is little impact from sporadic rain, certain rainproof measures are needed if the rain is heavy. Summer is generally the forbidden time for grafting. The reason is that it is hot and rainy in summer. If it rains after grafting, it is easy for rain to enter the grafting interface. In addition, the high temperature and rapid microbial reproduction will easily lead to the failure of grafting.

Therefore, I think that no matter what kind of grafting belt is grafted, it needs to be covered with a plastic bag to prevent rain in case of heavy rainfall. If you forget to cover the bag, you can pick a small hole in the grafting belt with a needle or pointed tweezers in time and use toilet paper to absorb water. If it is handled in time, it will generally not affect the survival of grafting.
