First, the advantages

1. Less loss of output Because the trunk has not been completely removed, more than half of the output can still be maintained during the year. 2. High safety factor If the scion is dead, the roots of the tree will not be affected and will not die. The second year will continue to be high. 3. Increased scion growth Since all trunks are not sawn off, the balance between the upper and lower parts of the tree is not destroyed, the roots are withered and dried, the nutrition on the upper part is sufficient, and the scion is at the corresponding top, maintaining the apical dominance, and the scion growth can be increased. Big.

Second, the technical points

1. Push down the main trunk and select the smooth part under the trunk from 30 to 50 centimeters from the ground. Saw the trunk 2/3, and cut 1/3 of the sawn cut, so that the tree is lying horizontally and sawing The excess section of the section exposes the lower kerf section. 2. Connect the upper and lower blades to the upper and lower blades and select the fine variety for the scion. 3. Pruning Due to the destruction of the conducting tissue of the fallen tree, the pruning should reasonably reduce the load to about 1/2 of the original load, and eliminate the dense branches and the diseased shoots. Scion management According to the management method of the general high tree accession, the management of lying down tree body is managed according to the conventional tree body, and after 3 to 4 years the new breed is removed and the fallen tree body is removed. In addition, after the main trunk is toppled, the tree head is directly placed on the ground and it is very difficult to rake the grass. Therefore weeds should be prevented from weeding within the canopy and affect yield.
