There are often mosses on fruit trees. Is there any way to get rid of it

Moss usually grows on the surface, branches and leaves, which weakens the photosynthesis of plants, affects the growth of trees and reduces the survival rate of trees. This has seriously affected the yield and quality of citrus fruits. Many old parks tend to grow moss. Moss absorbs the nutrients of trees parasitic on branches, weakens the nutrients of trees and makes them lose, while weak trees make trees fall into a vicious circle. Moss parasitic on fruits lacks photosynthesis. Small fruit has a certain influence on the appearance of fruit, and the loss of nutrients seriously reduces the quality of fruit, thus affecting its price. Moss attached to the surface will absorb water and fertilizer, while a thin layer will affect the infiltration of water and the exchange of gas in the soil. Soil permeability decreases, water retention and fertilization ability decreases, and root absorption weakens.

The growth law of moss: the moss in high humidity garden is heavy; High density citrus cultivation and lichen have poor permeability and are easy to grow; The old park is widely cared for, the old trees are weak and the moss is weak; The lower leaves are often used. Chemical fertilizer is easy to stimulate the development of moss.

Moss control measures: 1. Reasonable close planting, increase light transmission and ventilation. 2. Loosen soil and improve soil permeability. 3. Many fruit farmers use bark to remove moss. Artificial scraping of necrotic bark destroys the normal metabolism of plants. Over the years, the normal physiological structure was destroyed and the differentiation of buds was unbalanced. Spraying Sophora flavescens+garlic oil on the ground and branches can make moss wither and turn white, which has obvious effects on preventing and controlling moss and killing fungi in soil and branches. It is effective not only for citrus fruits, but also for mosses of mango, grape, bayberry, kiwi fruit and other fruit trees.

Effective methods to prevent and control moss: 1, timely ventilation and drainage, reduce soil surface humidity and reduce the occurrence of moss. 2. We should choose a more suitable fertilization method and pay attention to the balance of soil nutrients. 3. Improve soil quality to maintain soil quality, especially pH value and soil permeability. Soil improver Aolongle can be used to activate soil nutrients, balance various trace elements and improve nutrient utilization rate, that is, to improve plant root development and nutrient intake. It is essential to prevent garlic oil from spreading on moss. In the dry season, it can be sprayed 2-3 times throughout the season, and the moss will automatically fall off, effectively preventing the spread of moss. Garlic oil contains various thioether compounds, which are in direct contact with moss. In addition, we must consider nutrition, increase the potential of trees, increase the application of organic fertilizer, do not apply nitrogen fertilizer, and supplement trace elements to leaves. The second is to strengthen orchard management, reduce orchard humidity and improve orchard permeability. Moss appeared.
