What is the cherry dead tree?
Under Wang Xinrui’s guidance, the reporter came to her cherry shed. When she first entered the greenhouse, the reporter saw the yellow cherry trees on the leaves. Many piles of rotten leaves were piled on the ground, and many cherry trees were cut down and planed. Come out and fall to the ground.
Wang Xinrui said that 132 groves were planted in her shed. They were all in the thirteen years. They are now in full bloom. A tree can bring her more than a thousand bucks each year. The direct loss was nearly 30,000 yuan.
After listening to the introduction, Zhang Chuanyi observed these dead cherry trees and made people plan a tree. After observing several trees, Zhang Chuanyi reached a conclusion.
"These trees have acquired a disease called white feather disease. There are obviously some white hyphae on the roots. These mycelia have caused the rot of cherry trees," said Zhang Chuanyi.
After talking about the disease of white lines and feathers, Zhang Chuanyi discovered another disease in another tree. He said: "The dead tree of this tree was caused by root nodules. This is called root cancer disease. Root cancer is a bacterial disease. After the tumor grows, the roots absorb the nutrients poorly, the weaker tree causes the yellow leaves, and finally it causes the whole tree to die."
After reading the illness, Zhang Chuanyi gave a solution: root cancer is a bacterial disease, it is best to use bactericidal drugs, such as streptomycin sulfate, can be killed, DT or copper bacteria, to carry out the irrigation .
For the prevention of white feather disease, Zhang Chuanyi said that with 43% of tebuconazole 2000 times, plus 50% of the 500 times of dexamethasone, or plus 50% of the eubacteria 250 ~ 300 times, plus rooting agent , One to irrigate the root, can well control white feather disease.
