Q: After the walnut seedlings are brushed and putty powder, will they die? Is it due to the use of putty powder?
Dong Zhishui replied: Upon inquiry, it was learned that a large number of high-quality walnut seedlings were planted in this place. In order to visually look good, the farmers painted a large amount of putty powder for the wall, and some putty powder brushed the whole tree seedlings. The saplings died. Some of the saplings were painted with putty powder underneath and the upper part was not painted. The unpainted parts were dry green lacking moisture. Pulling out the roots of the saplings is still very good, but there is a clear lack of moisture in the tree pits.
As for the behavior of putty powder, it is very absurd. Putty powder is a kind of decoration wall paint. In addition to talcum powder, putty powder raw materials also contain natural vegetable adhesives. The walnut skin pores are coarse, and the putty powder coating creates an airtight and airtight environment, making it easy for the tree to die. Lime is a strong alkaline bactericide. The lime water applied to the tree trunk will naturally crack and will not affect the breathing and transpiration of the lenticels.
I do not know whether the reader said that the walnut seedlings are seedlings or grafted seedlings, if it is seedlings, it is recommended to cut off the ground as soon as possible, to strengthen water and fertilizer management, to promote the emergence of new shoots rhizomes, and then picking buds in the summer and fall season or grafting grafting; If it is a grafted seedling, check whether the grafted joint is alive. If the grafted seedling is not painted near the interface, leave one or two buds at the top of the interface to cut it, strengthen the management, and promote the emergence of new shoots.
