Walnut tree management method in June
Since the walnut suffered from frost damage in April this year, the amount of the walnut was reduced. Therefore, the excess of water and nutrients in the walnut tree at the beginning of the result was prosperous, and it was necessary to carry out the topping to increase the fruit setting rate.
First, the length of the heart
Generally, 5 or 6 leaves are used for topping, because the length of the topping is more than 5 or 6 leaves, and the base is bare. In the coming year, the base is bare and the top of the light is the result.
Second, pick the heart under the cut, try to stay outside the bud
The outer buds are good for expanding the canopy, so try to keep the outer buds and then pick the heart. This can promote fruit tree growth and increase the rate of results.
Third, the number of topping
Look at the new shoot growth leaves, there are no more than 5 or 6 leaves, generally last until the end of June.
Fourth, not picking new shoots
1, the new shoot base 5, 6 leaf disease, the insect is serious, do not pick the heart
Such as: due to the rain in the first half of this year, extensive management of the orchard, remove the good tips that can supply nutrients, leaving 5 or 6 leaves of serious black spot disease, will fall off early, life is difficult to protect, but can not supply walnuts And the walnut tree body needs nutrition, and it will weaken the tree potential, so the roots of the new shoots are not able to pick the heart.
2, fruit table secondary tips, do not pick the heart, only a new tip at the end of the month
The fruit top is the new tip that supplies walnut nutrition nearby. When picking the heart, you need to leave a fruit stand and the other to be removed.
3. After the topping of the new shoots, the excess new shoots should be removed.
After the topping of the new tree, the new shoot will come out with 5 or 6 tips. After the second picking, the 5 and 6 tips will not only affect the ventilation and lightness of the tree, but also the quality of the walnut.
Topping is an important part of the cultivation of many fruit trees, because topping can ensure the nutrient supply of the main branches, increase the yield, and do not underestimate the process of walnut planting.
