Early spring orchard management
Although the temperature is still low at the moment, as the winter goes, germs and pests will gradually become active. In early spring, the orchard needs to grasp the following points:
Saw to the rot that has not been saved, should be removed with a hand saw, pay attention to saw the mouth to be smooth, if space can be bridged.
Cut off pests and branches, dead branches should be promptly cut off, get outside the park, concentrated burned.
Scrape the diseased skin and necrotic tissue in time and remove the overwintering pests in the bark cracks. Squeegeeing is best done while the sap is flowing. It should not be too early or too late. Premature trees lose much water, and most pests do not have activity; late-rot disease has spread hazards and pests have spread out. The rot disease should be scraped to a depth of 0.5 cm from the skin, preferably into a shuttle to facilitate healing. In addition, we must completely scrape off the old presbyopic and rotenia tumors. We should not miss a single tumor. Perennial and 1-year-old tumors must be scraped. The depth is dominated by white trees and green trees. It must not be too deep or too shallow, and at the same time, it should be deeply buried. According to the survey, the scraping of skin scrapings has been reduced by more than 5%, and there has been very little outbreak of hawthorn leafhoppers.
Apply all kerfs, cuts, and irritants to all rot-purified clarifiers to prevent loss of water from wounds, prevent germ invasion, and promote healing.
Sick branches, diseased fruits, and broken bark under the trees on the clear trees should all be cleaned up outside the garden. The defoliation does not have to be cleared outside the garden and can be used as a fertilizer. Digging organic fertilizer and chemical fertilizer digging pits are concentrated deep below 25 cm on the surface.
In the early spring, two sprays of medicine are required. The first time the flower bud just germinates, 5 Baumite lime sulfur is sprayed, because when the flower buds just germinate, the main component of the lime sulfur is released by the polysulfide to kill the insects. And the role of bacteria; another lime sulfur is a strong alkaline drug, can penetrate and erosion of the cell wall and pest parasite waxy layer, while a strong alkaline environment is also not conducive to the survival of pathogens; lime sulfur spray on the tree A layer of protective film is formed, making it difficult for foreign pests to invade, while causing the diseases and insects under the membrane to die without oxygen, and has a good control effect against overwintering pests and pests. Practice has shown that the pests are basically not resistant to lime sulfur. Sex. The second time in the flower red season, spray 2000 times the solution of Benzene plus 5,000 times the Fuxing solution, the last remaining pathogens and overwintering pests further killing.
