For the purpose of promoting flower bud differentiation and preventing excessive vegetative growth, new shoots should be controlled by the method of fresh shoots. That is, the new shoots that have not stopped growing will be picked up, and the picking position will be generally bounded by a half leaf. After picking the heart, it will stop for 10 to 15 days to send out secondary shoots. When it reaches 15 to 20 centimeters, it will be picked again for the second time. Still half a leaf as the boundary.
After the cherry tree was harvested, the branches with small angles on the first branch can be pulled to make the angle between the angle and the main branch of 70 to 80 degrees. It can improve the ventilation and light transmission of trees, and at the same time ease the growth potential, which is very beneficial to flower bud differentiation. Pay attention to the mat before the pull to prevent damage mats, so as not to pull the big branch of the skin.
Excessive pruning of large branches, and tree closure, is one of the important causes of the debilitating cherry tree, reduced resistance, and the occurrence of diseases and insect pests. The younger the cherry tree is, the stronger the resistance is, and the pruning of a large branch can improve the overall stress resistance of the cherry. At the same time, through pruning, reduce excessive flower buds and ensure that the next year's fruit is larger.
Removal of large branches should grasp the following aspects:
First, large branch pruning should be carried out from top to bottom. Can not be rushed too much. The large branches removed in summer pruning are about 15% to 20% of the total amount. It is removed year by year according to the condition of the tree. Generally, it is appropriate to complete trimming in 3 to 4 years. . Maintain a relatively dense overall tree shape with a relatively thin main branch above and a lower main branch below.
The second is based on the length of the resulting branch. As a result, the longer the branch, the earlier it needs to be removed, and the more retracting the fruit branches. The tree is compact.
The third is to selectively remove the shoot growth. New shoots with small growth should be removed first.
The fourth is to remove the mastery of time. Removal of large branches can generally be carried out from mid-July to mid-July. In some cases, it can even be carried out during the fruit harvesting period. For instance, the heads of fruits and vegetables may be sawn off under the heads of the fruit after harvesting. Can be. In addition, sawing large branches is generally to avoid the period of heavy rainfall and prevent the flow of glue.
Note that when large branches are removed, it is generally necessary to leave a certain length of branches at the trimming site to promote wound healing and prevent excessive retraction of fruit branches.
Hearing Protection refers to devices used to protect the ear, either externally from elements such as cold, intrusion by water and other environmental conditions, debris, or specifically from noise. High levels of exposure to noise may result in noise-induced hearing loss. Measures to protect the ear are referred to as hearing protection, and devices for that purpose are called hearing protection devices. In the context of work, adequate hearing protection is that which reduces noise exposure to below 85DB over the course of an average work shift of eight hours.Different types of hearing protection may be utilized to maximize hearing protection. OSHA regulations dictate whether hearing protection is required and if the company must participate in a hearing conservation program.
