Management experience of planting pear trees in early spring

"rational distribution of tree storage nutrients and reducing useless consumption is one of the important techniques to promote the normal growth of trees and produce high quality fruits. During this period, the useless consumption of trees can be reduced by wiping buds and thinning buds, which is an important step in the management of pear trees in early spring. " Wu Sijiang, an agronomist from the Agricultural Technology Center of Jine Town, Longchang County, introduced early spring management techniques to pear growers.

He said that after the spring buds sprout, they should be erased when they grow to 2mm or 5mm. Sprouts should be sprouted as soon as possible until flowering. If the delay time, although it can reduce the occurrence of overgrown branches, but the loss of storage nutrients is more, easy to weaken the tree potential. After cutting off great skills in winter, it is often easy to form useless skills or useless skills, which should also be erased in time. Buds can be removed from scale shedding to pre-flowering, but it is appropriate to remove buds when they are exposed. When thinning buds, you can press the buds from top to bottom with your fingers to break the pedicel. At the same time, attention should be paid to the protection of young leaves in inflorescences. When thinning buds, generally retain an inflorescence according to the standard of about 20 cm, with fruit to control the upper growth; when removing the late budding buds, when the inflorescence protrudes, the accessory inflorescences should be removed in time to retain normal flowers. When the pollination conditions are good and some flowers have been fertilized and can meet the requirements of high yield, stone-sulfur mixture can be sprayed in combination with pest control to kill the late flower stigma and play the role of flower thinning.
