1. The pathogens and pests of various diseases that have occurred in the Qingyuan tree during the fruiting period, they all choose diseased leaves, diseased fruits, weeds, etc. as wintering places. Therefore, after the fruit is harvested, the litter, rotten fruit, weeds, etc. in and around the orchard should be carefully cleaned.
2. Some disease-causing bacteria are overwintered on the diseased branches that have been infected, and some pests overwinter with insects and eggs on diseased branches or young branches. Therefore, when combining winter shears, these dry branches and diseased branches should be cut off, and the diseased fruits remaining on the trees should be removed. Burning the branches with pathogens and eggs can effectively reduce the wintering base of pests such as aphids, heartworms, and hibiscus, and delay the occurrence of pests and diseases.
3. Bark bark Some germs and pests are easy to choose to overwinter in the rough skin and cracks of the trunk, such as apple small heartworm, pear small heartworm, red spider, rot disease, round disease. The rough skin, skin, and skin of these trunks should be scraped off and burned out. After the skin is scraped, it should be treated with chemicals.
4. The white trunk of the tree trunk and the white agent under the big branch can prevent freezing damage and have the functions of sterilization and pest control. It can also weaken the absorption of solar radiant heat from the trunk, delay the germination and flowering of the fruit trees, and avoid frost damage in early spring. The commonly used formula is: 10 parts of water, 3 parts of quicklime, 0.5 parts of stone sulfur mixture, 0.5 parts of salt, and appropriate amount of oil. First use a small amount of water to open the lime, pour the oil into the mixture, add water to make the lime milk, and finally add the stone sulfur mixture and salt water. You can also add the adhesive to extend the life of the whitening agent. You can also use 10 parts of lime. 1 part of sulfur powder, 40 parts of water is added. Generally, the brushing time is in the middle of November, and the main parts and branches are 1.3 meters below.
5. After the fruit is sprayed, the insecticide and bactericidal agent should be sprayed according to various pests and diseases that occur during the fruiting period. It can be sprayed 1 or 2 times with 4 to 5 Baise of stone sulfur mixture after clearing the garden, which can effectively prevent pests such as red spider, pear black spot, apple rot, and grape black pox.
6. The trapped pests use the larvae to have a habit of choosing for wintering places. In winter, they hang grass on the big branches or trunks of the trees, attract more pests to the grass handles, and then remove the grass to concentrate the burns.
7. There are many germs and pests that turn over the soil in the winter, such as apple flower rot, peach worm, grape worm, etc. The soil of the orchard is turned over before freezing, and some worms can be directly injured and killed, lurking in the soil. The pests in the field can be frozen, dead or eaten by birds, and surface bacteria and pests can also be suffocated into the soil. (Henan Daily, Chen Xianxia)
