Flowing gum is a common disease of stonefruit such as peach, apricot and plum. It has also occurred in apple orchards in recent years. Once the disease occurs in fruit trees, it begins to flow and the tree declines and even destroys the garden. When the fruit is damaged, the colloids seep out of the fruit surface; so that the fruit lengthens, the quality deteriorates, and it is difficult to eat. The direct cause of flow of fruit trees is the damage to the branches of tree branches, such as mechanical wounds, frostbite, sunburn, excessive trimming, and injury caused by phytotoxicity. The second reason is the pests and diseases, fungal and bacterial infections, dry rot, rot, scab and so on; Tianniu, Giardaki and other diseases and pests cause fruit trees to flow at multiple locations. The third reason is that fluids caused by physiological diseases, such as poor affinity of soil rootstocks, overload, etc. can lead to tree resistance fold. Practice has shown that the following four methods for controlling fruit flow are good. 1. To cultivate robust trees and apply organic fertilizers, combine inorganic fertilizers and organic fertilizers, combine a large number of elements N, P, K with trace elements, and formulate fertilization. Timely irrigation and rowing should be particularly well-enclosed with frozen water, fertility and fertility, loosen the soil, so that the tree enhances resistance to flow glue. 2. Strengthen tree protection The orchard should protect the tree body when it is done and avoid causing wounds. When cutting pruning mouth smear set seal, sterilization, healing as one of the wound protection agent, such as "fruit effect healing agent"; trunk in the early spring early winter white; in case of high temperature or ultra-low temperature to take emergency measures, such as using the most simple effect of "spray "Water law" eased to prevent sunburn and frostbite. 3, spraying pesticides to prevent budding before the fruit tree spray 5 Baume degree of lime sulfur, branches of plastic spray. During the growing season, it is sprayed with mancozeb carbendazim, bactericide and other fungicides to kill sterilizing protection. From May to June, it sprayed three times, two intervals and half months, and sprayed 1-2 times from August to September. For insect pests such as Red-necked beetles and Giardia, pests and branches should be cut in time. The omethoate was coated 30 times with stems and then wrapped with plastic film to kill its larvae. 10% cypermethrin EC was sprayed twice in the early stage of eclosion, with a 10-day interval between them. 4. The large class scraping cures the old cracked skin before entering the winter, especially when the branch is divided. For branches that have flowed, first use a knife to scrape off the flow glue and old cracks. After the tender skin is exposed, smear 1-2 times with the stone flow mixture or smear with 5 Baume degree lime sulfur before painting. . In recent years, we used lime powder to apply to flow plastics, which not only damages the tree but also is economical and convenient for operation. It is worth promoting. Liquefied rubber flow is best carried out in cloudy and light rain, because the glue flow out of the bark is strong and easy to make the lime powder stick. We can also scrape off gums from the diseased area and treat it with thiophanate-methyl wood ash. The method is to equip the same amount of thiophanate-methyl and ash to make a paste, apply it to the wound and wrap it in a film, and wrap it in 2 weeks. The film will be cured. We must constantly check the fruit trees, and immediately find out that they will immediately prevent and control the flow of glue before the onset of the disease to ensure that the tree grows robustly, seize high yields and stabilize production.
