What is the new method for the application of paclobutrazol in fruit trees?
1. The trunk is perforated and buried. Punch holes in the lower trunk of the main branch of the base (one hole under the three main branches, a total of 3 holes). The size, depth and biopesticide dosage of the base are determined by the size of the tree, the thickness of the trunk and the age of the tree. . Drill a hole with a diameter of 0.6-0.8 cm and a depth of 3 to 5 cm by hand, and adjust 15% of the paclobutrazol powder into a puree with a small amount of water. According to 3 to 5 years old saplings 6 to 9 grams, 6 to 10 years old trees 10 The dose of ~15 grams was buried in three holes, and the amount of the three holes was the same as possible, so that the agent was evenly transported to all parts of the tree. The Qiaohua dense planting tree without main branches has three holes uniformly on the circumference of the trunk, and the height from the ground is convenient for operation. After filling the drug, the hole can be closed with yellow mud. 2. Trunk coating method. The oligo-mature tree of adult age scrapes off the old warp on the trunk, and the smooth saplings of the trunk can not be scraped. The width of the coating ring is about 1/3 of the circumference of the trunk, and the paclobutase powder with the concentration of 15% is 200 times. The film is tightly wrapped with a film to keep the pesticide ring at a certain humidity and is easily absorbed and utilized by the tree. The above two methods allow the medicine to directly enter the fruit tree through the stem tissue, thereby reducing the distance of soil roots absorption and transportation, and the effect is quick. It is not restricted by time, climate and soil, and can be applied all year round.
