There are so many upright branches growing at the top of the canopy, if it is not treated in time now, the middle and lower flower buds are difficult to differentiate, and even the best varieties will be low-yield gardens in the coming year. This type of tree, more than 50% of the strong branches and long branches on the head should be removed, and the sooner the flowering effect, the better. Now the main task is to control the top, less tossing in the lower part of the canopy.
Q: How do walnut trees hold their crowns?
A: Remove more than 50% of the long branches on the head of the tree, and the lower backbone branches will not move for the time being.
Guotai vice-tip three to two, two to one, we have repeatedly stressed, some people just don't listen. No, after all the fruit table side shoots are removed, the flower buds that have been formed behind the fruit are now germinating, and it is difficult to become flowers on the autumn shoots, and the yield will definitely be greatly reduced next year. As long as the variety is good, the buds on the secondary branches of the fruit table are full, and they can also be used as scion.
Q: What is this problem on walnut leaves?
A: Is the back of the blade normal? From the analysis of the current situation of the front of the leaf, the back of the leaf should be caused by the harm of military insects, the size of mung beans, flying with wings, and living in groups. Kill it with 3721 or Long Lile.
If the back of the leaf is normal and white spots appear on the leaf surface, two points should be noted when spraying later:
First, the high temperature at noon should not spray, in the morning and evening is appropriate;
Second, when dispensing drugs, do not artificially increase the concentration, according to the instructions of the drug strict operation.
