How to trim the winter planting walnut garden

In the cultivation of the result tree and branch groups, we must pay attention to small and large, thin and dense. In the lower part of the tree, 1 to 2 large branches (restricted branches) should be taken, so that the water and nutrients flow from the lower part, inhibiting their strong apical dominance, avoiding the upper ones and causing the flowers to move upwards and the lower ones to die. When cutting in winter, no two-year-old branches are left, leaving no fruiting branches. Only the good result branches with a thickness of 0.4 cm or less are selected. The lower branches are shorter, and the top leaves only one branch, spirally arranged, and single branches updated. Yes, all others will be eliminated. Another point worth noting is that there are two reasons for the upper part of young trees in the dry trunk: one is to avoid bending the middle stem and affect the lower light; the other is because the fruit trees have the advantage of nutrient concentration, so the top does not stay. As a result, in order to reduce the amount of nutrients transported to the upper part, the nutrient supply is unbalanced and the lower fruit is small and colorless. 1 to 2 years, the top of the sapling does not take the lead, wait until the middle of the rough and fall.
