Apple's face disease focuses on prevention

Apple blossom face disease is a manifestation of viral disease, mainly in the fruit. The surface of the diseased fruit is uneven, and there are patches of different colors on the surface, forming a flower-faced shape. This disease is difficult to treat, so early prevention is particularly important.

Cautiously selecting seedling apple blossom facial disease belongs to virus disease. Many times the virus has hidden in the tree body from the seedling stage, but it does not have any external symptoms until the trees are gradually exposed. Therefore, the prevention and treatment of flower face disease should start from the seedling selection. Need to be alert to the virus vaccine.

To strengthen the management of apple blossom face disease is often very fast, so when a small number of face disease strains are found, they must be excavated in time to ensure that most of the fruit trees are not invaded; organic fertilizers and trace elements play a role in the suppression of viruses. In the case of too many viral trees, applying more organic fertilizers and trace elements can relieve symptoms; pear trees can also carry the Facial Disease Virus. It is best not to bring the apple orchard too close to the pear orchard to avoid foreign virus infection. Facial disease virus can spread through the roots of trees, so it can appropriately widen the spacing between trees to reduce the possibility of root propagation; Facial disease is often more obvious when the tree is overly tired, reasonable pruning, increased tree vigor, can increase tree resistance Ability to reduce disease. In addition, because the Facial Disease virus is easy to spread through the pruning tool, the tool must be disinfected after each virus tree is trimmed (fire, hot water, and lime sulfur disinfection).

Greenhouse Automatic Proportional Pump

Fertilizer pump mounted directly on the pipe, the kinetic energy of pipe flow to drives the pump to work at a set ratio to suck high erconcentration drug or quantitative fertilizer in to the pump. After mixed with the water and delivered to downstream. No matter How to change the water pressure, Drug or fertilizer will be mixed and discharged according to a certain proportion.
