一、幼树的修剪1.定干:定干的目的在于控制第一层主枝的高度、枣粮间作地树势较弱的品种。定干高度在1.4米左右,树势强的品种可在1.6~1.8米之间,纯枣园以11.22米为宜。定干高度确定后,向上留4~5节作为培养第一层主枝的整形带,截除顶梢,并剪除剪口下的二次枝。如果只剪一剪子,截去枣头第二年就不容易抽生出新的枣头向上生长。对整形带内的二次枝,要保留1～2节,在节位前面重截,使主枝尽可能从保留的二次枝上抽生,形成第一层主枝,如果在定干高度内没有健壮的二次枝着生,可适当提高定干高度。2.清干:幼树定干后要对整形带以下的分枝,从下往上逐年清除,但应注意不要一次完成,每年清干应掌握不超过整个树
First, the pruning of young trees 1. Fixed dry: The purpose of dry set is to control the height of the main branch of the first layer, jujube grain between the weaker species. Set at a dry height of about 1.4 meters, strong tree vigor varieties can be between 1.6 to 1.8 meters, pure jujube to 11.22 meters is appropriate. After determining the height of the dry, leave up to 4 to 5 as the training of the first layer of the main plastic band, cut off the top, and cut off the second branch under the cut. If you only cut a pair of scissors, truncated jujube first year is not easy to pump up a new jujube head growth. For the secondary strands in the shaping band, keep 1 to 2 knots and re-cut them in front of the knuckles so that the main straws will be aspirated from the remaining secondary branches as much as possible to form the first layer of main knuckles. There is no robust secondary branches, may be appropriate to increase the fixed dry height. 2. Drying: After the young tree is fixed to the plastic band with the following branches, year by year from the bottom to remove, but should be careful not to be completed once each year should be mastered not more than the entire tree
