Abstract:
Provided is a method for preventing and controlling the citrus greening disease and yellows disease by applying a biological carbon fertilizer. Hai Jin Gang carbon fertilizer is used as the main material to rapidly increase the effective carbon content in the soil. Pit-digging for the application of fertilizers is replaced with the application of fertilizers with irrigation water on the earth's surface to rapidly replenish carbon in the soil. Grass serves as a natural carbon source for carbon supplementing of the soil. In order to make use of grass, grass is planted or self-sown grass is allowed to grow in orchards, and clean tillage of the soil is replaced with no-tillage or minimal tillage to grow grass. Girdling and ring girdling and cutting-back pruning are cancelled, a trunk as a central leader is cultured with concentration, the tree structure has a distribution of 2-3 layers, and each layer has 2-4 lateral branches. Mature trees have a desirable planting density of 3 m X 5 m per mu, aeration and photopermeability are maintained across the whole orchard, and one fruit is allowed for every 60-80 leaves. By using this method, the incidence of plants can decrease, infected trees can be cured earlier, and the fruits are fragrant and sweet and are of high quality and stable yield. With the same management and investment, the increased range in yield can be up to 30% or more. No tillage is needed during the whole process, thereby saving labor and time. The dosage of fertilizers is decreased, thereby alleviating the problems of soil hardening, acidification, salinization, etc.
