Effects of different tending measures on growth and yield of Juglans regia L

In the walnut orchard with the same site conditions, four kinds of tending measures were taken to observe and compare the effects of different tending measures on the ground diameter growth and dry fruit yield of walnut trees. After three consecutive years of observation, the results showed that: under the same site conditions, strengthening the tending management measures is conducive to improving the growth of the ground diameter of walnut trees and promoting the fruit and high yield of walnut trees;there are differences in the effects of different tending management measures on the ground diameter growth and dry fruit yield of walnut trees. The more effective the tending management measures are, the better the growth of the walnut tree is, the more conducive to the high yield of walnut fruit. The more extensive the tending management measures are, the worse the growth of the ground diameter of the walnut tree is, and the lower the fruit yield is.
