Kiwifruit winter clearing five measures
Before cultivating the soil, the soil is chilled by 20~30 cm, so that the pests turned to the ground are frozen or eaten by birds. Combined with irrigation, change the environmental conditions of the soil and reduce the source of overwintering insects. Scrape the old and old skins and use the winter dormancy period to scrape off the rough skin and the skin of the main trunk of the fruit tree, and kill the overwintering insects such as red spiders and scale insects hidden in the rough skin, skin and cracks of the branches. The affected ulcers are scraped off in time, and the plastic film is laid under the tree when scraped. The thick old skin and the sick belt are scraped out of the orchard and burned intensively. Cut off the pests and diseases combined with winter pruning (from mid-December to early January), cut off infected branches with disease, disease, eggs and weak growth, and take them out of the park for centralized destruction. When pruning in winter, first cut the tree, then cut the diseased tree, and pay attention to the disinfection of the pruning tools (scissors, saws), which can be treated with 75% alcohol solution. The large wound after pruning can be protected by the original drug of 1.6% thiazolone ointment, the original drug of 2.4% humic acid copper sulphate, and artificial bark. After cleaning the pastoral pruning, it is necessary to cut off the dead branches, the dead fruits of the pests and diseases, the remaining bagging and other sundries, the fallen leaves, the scraped rough old skin, the diseased insects, the weeds, the fruit and fruit waste, etc. Provide items for wintering places for pests and diseases, thoroughly clean out the orchards, and burn them intensively to eliminate the overwintering pests hidden in them. After the fruit tree is pruned, the whole tree is sprayed 1~2 times to protect the wound after the leaf is cut, and the high-efficiency and low-toxic agents such as myclobutanil + chlorpyrifos, copper hydroxide, stone sulfur mixture, etc. are selected. Alternate use to kill pathogens and wintering pests on trees. Disclaimer: Some articles on this website are transferred from the Internet.
