Pear fruit harvesting is an important period for tree nutrient accumulation and flower bud differentiation. Therefore, good orchard management during this period is of great significance for promoting flower bud differentiation, improving cold resistance of fruit trees and increasing the output in the coming year.
Deep-turning tree trays: There are many pathogens and pests in the winter in the soil. During the dormant period, deep turning is performed. The wintering insects, cockroaches, and cockroaches are turned to the ground to freeze to death, or they are deeply turned to the depths of the soil. Unearthed.
Clearing orchards: When the leaves of the pear orchard are basically finished, the leaves must be cleaned in time to remove the weeds, and they must be buried or burned in depth to eliminate overwintering pests and increase the fertility of the orchard soil.
Pull branches in autumn: At this time, pull branches have the characteristics of easy pull, fast setting, good effect of slowing down, and high flowering rate. In the fall, branches should be mainly open angles with non-backbone branches. The opening angle of the branches can be around 85, which can effectively alleviate the early results of tree vigor. The opening angle of the branch with a small opening angle can be controlled at 40-50, and the pear tree with a large tree age can increase the opening angle appropriately.
Scrape Bark: There are many overwintering pests in the pear bark seams and linings, such as Pyrosphaeridae, Red spider, etc. Scrape bark in the winter can scrape out the insects and eggs hidden in the bark and concentrate them to eliminate them. The density of insects in the coming year. Scrape skin to grasp the fruit trees light scratches, see the yellow and green bark prevail. Pear bark should be heavily scratched and scratched to see the red endothelium. Be careful not to injure the phloem while shaving.
The trunk is painted white: It is advisable to paint white at a height of 1-1.3 meters. Preparation method of whitening agent: take 2 parts of lime, 0.1 parts of salt, 0.1 parts of animal and vegetable oil, 0.2 parts of cow dung, and 10 parts of water. Liquefied lime is first used to make lime milk, then animal and vegetable oil and salt are added, and water is added by mixing. Pour milled manure into the mixture and serve. The amount of coating is not preferred.
Pouring frozen water: Before the soil is frozen, the entire garden shall be irrigated with frozen water to protect the root system from frost damage.
Chemical control: The pear orchard with heavy pests will be sprayed with 45% crystal lime sulfur 100 times for 4 times to kill the pests that have just entered dormancy and reduce the occurrence of pests.
Cut off pests and branches: In combination with pear winter cuts, branches, dead branches, dead shoots, and dead fruits of aphid holes or eggs are cut and burned together.
