Embodiment 1
[0040] A method for acclimating dwarf and premature birth of fine fragrant walnut, comprising the following steps:
[0041] 1) Young trees:
[0042] A. Butcher branches: control the growth of trees by butchering branches, specifically, when the saplings of the fragrant walnut grow to 1.5m, butcher the tip at 1.2m;
[0043] B. Bud picking: Control the growth quantity and direction of branches by picking buds. Specifically, in the second year, redundant tree buds are removed, and 3 buds are left. The best buds are located in the sunny direction. As the main branch bud; the distance between the three buds is 25cm, and they form an angle of 120° with each other, the base angle of the three buds is 60°, the waist angle is 70°, and the tip angle is 55°;
[0044] C. Shaping: Control the shape of the tree through shaping. Specifically, in the third year, the amount of branches is controlled according to the terrain. Prune the main buds left in step B and leave 3 side buds, and remove...
Embodiment 2
[0050] A method for acclimating dwarf and premature birth of fine fragrant walnut, comprising the following steps:
[0051] 1) Young trees:
[0052] A. Butcher branches: control the growth of trees by butchering branches, specifically, when the young walnut trees grow to 1.4m, butcher the tip at 1.15m;
[0053]B. Picking buds: Control the number and direction of branch growth by picking buds. Specifically, in the second year, excess tree buds will be removed, and 3 buds will be left. The best buds are located in the sunny direction, and the 3 buds are ringed into 360° as Main branch bud; the distance between the three described buds is 20cm, forming an angle of 110-130° between each other, the base angle of the three buds is 60°, the waist angle is 70°, and the tip angle is 55°;
[0054] C. Shaping: Control the shape of the tree through shaping. Specifically, in the third year, the amount of branches is controlled according to the terrain. Prune the main buds left in step B a...
Embodiment 3
[0060] A method for acclimating dwarf and premature birth of fine fragrant walnut, comprising the following steps:
[0061] 1) Young trees:
[0062] A. Butcher branches: control the growth of trees by butchering branches, specifically, when the young walnut trees grow to 1.6m, butcher the tip at 1.25m;
[0063] B. Bud picking: Control the growth quantity and direction of branches by picking buds. Specifically, remove redundant tree buds in the second year and leave 3 buds. The best buds are located in the sunny direction. When the buds are not good, keep 4 buds, all of which are used as the main buds; the distance between the 3 buds is 30cm, and they form an angle of 110-130° between each other, and the base angle of the 3 buds is 65°. Angle 80°, tip angle 65°;
[0064] C. Shaping: Control the shape of the tree through shaping. Specifically, in the third year, the amount of branches is controlled according to the terrain. Prune the main buds left in step B and leave 3 side b...
