Planting method for comprehensive control of citrus Huanglongbing

Abstract

The invention discloses a planting method for comprehensive prevention and treatment of citrus huanglongbing, and the technical problem to be solved is to prevent and control citrus huanglongbing. The planting method of the present invention includes: fertilizing underground in spring, fertilizing on the ground, pruning branches and leaves, applying biological pesticides, spraying or dripping liquid fertilizer after flowering, spraying diluted foliage fertilizer, pruning branches and leaves, spraying or dripping liquid fertilizer during the fruit expansion period , Spray diluted foliage fertilizer, trim branches and leaves, cut off diseased branches, dead branches, diseased leaves and diseased fruits after harvesting, sterilize and eliminate insects. Compared with the prior art, the present invention carries out comprehensive prevention and control in the citrus park, increases the organic matter and mineral elements in the soil, improves the water and fertilizer retention capacity of the soil, and three-dimensional fertilization supplies sufficient nutrients to the tree, effectively promotes the growth and development of the tree, and restores the citrus. The self-resistance ability of the tree can improve the ecological environment of the rhizosphere and the phyllosphere, cooperate with the pruning of branches and leaves, and spray biological pesticides to create a good growth condition, reduce the chance of Huanglongbing transmission, and control the spread of Huanglongbing.

Description

technical field [0001] The invention relates to a method for preventing and treating plant diseases, in particular to a method for preventing and treating citrus huanglongbing. Background technique [0002] Citrus huanglongbing is mainly caused by a bacterium named Candidatus liberibacterasiaticus, which is transmitted and spread among citrus trees by psyllids. It mainly harms the new shoots, young leaves, flowers and fruits of citrus trees. In the early stage of citrus huanglongbing, a few new shoots of citrus huanglongbing appear in the dark green crown, commonly known as "Jinhua", and the leaves appear evenly. types of symptoms. The fruit setting rate of fruit trees is extremely low, the fruit is small, deformed, and of poor quality, and some varieties have "red-nosed fruit" in the near-maturing stage. With the development of the disease, there are more and more yellow shoots, and some leaves are like mosaic leaves similar to zinc deficiency. Within 3 to 5 years, the ...

Problems solved by technology

According to incomplete statistics, more than 40 million diseased trees in Guangdong, Guangxi and Fujian have been cut down due to infection, which not only caused economic losses, reduced farmers' income, but also affected the prospects for the sustainable development of the local citrus industry.

[0003] The prior art prevents and controls citrus greening disease by strengthening the quarantine of seedlings, cutting down diseased trees, spraying chemical pesticides to kill psyllids, and establishing new disease-free orchards. Production reduction and quality decline, the economic loss caused by fruit farmers due to production reduction and loss of harvest
