What effect does the rainy day have on the newly grafted fruit trees? What is the basis?

The survival rate of grafted fruit trees in summer is high, and bud grafting is simple. However, it is often rainy and cold, which leads to poor healing of grafting method and even leads to plant death. The adverse effects on grafted fruit trees are: the grafting method can't heal when it meets water, and the cambium of fruit trees is a thin meristem between phloem, which has strong working ability in daily life. The grafted fruit tree is a cambium of glued wood and budding, which continues to grow in divided cells.

Continuous rainy weather will lead to relatively high humidity in grafting environment, which will endanger the digestion and absorption of O2. Peach trees are bound with plastic film after grafting, which will not completely block the gas, and the grafting mechanism can grow and develop normally. In rainy days, O2 will be blocked, which will endanger planting activities. When newly grafted fruit trees encounter rainy days, it is easy to cause wound inflammation and bacteria, which makes the grafted parts shrink. Continuous rainy weather will reduce the temperature, and the grafting mechanism will heal slowly. When the temperature is below 20 degrees, the growth and development of the grafting mechanism will be very slow.

If it is less than 10 degree, the grafting method will not heal, resulting in unsuccessful grafting method and weak binding of plastic strips, so the budding is not easy to cater to glued wood. Precipitation enters the affected area, and water is stored in the wound, which leads to insufficient oxygen at the joints and harms the natural inhalation of the budding of sticky wood. The stored water will continue to cater to the small cracks that are not tight, penetrate into the internal structure of the wound, and form an isolation layer between the bud grafting and the glued wood, so that the wound cannot heal at all.

In the end, bud grafting itself consumes all nutrients and cannot be planted. To bypass the rainy day grafting method, this temperature will reduce the survival rate. Grafting with fresh-keeping bags tied tightly. It's okay. Be sure to wrap it up. If the bag is not sealed. Will greatly reduce the survival rate, as long as the package is tight, there will be no problem. After the rain stops, you can't touch the bud handle with your hands. Most of them fall off at the touch. Actually, they are in stock. The bud is small and dry, and you can see the end without using your hand. In that case, those who can live by themselves will not live.
