Method for preventing and treating jujube witches broom by using anti-broom stock

Abstract

The invention discloses a method for preventing and treating jujube witches broom by using an anti-broom stock. The method comprises the following steps of: (1) cutting new shoots of anti-broom wild jujubes in a jujube witches broom occurrence area, cutting and rooting, and transplanting to a nursery garden; collecting seeds of the anti-broom wild jujubes and sowing in the nursery garden; and after the nursery stock reaches the grafting thickness, screening to obtain a high-resistance or immune strain for the jujube witches broom in a mode of continuously and intensively inoculating branch bark blocks of a broom tree and eliminating diseased plants at any time; (2) establishing a cutting orchard and propagating the high-resistance or immune strain for the jujube witches broom; (3) breedingjujube seedlings by using an asexual propagation material of the anti-broom strain as a root stock or an intermediate stock to fulfill the aim of preventing and treating the jujube witches broom; and(4) bridging the anti-broom stock on a trunk of a tree body of a planted big tree which is not diseased or is diseased to achieve the effect of preventing or treating. The method adopts an anti-broomresource of Ziziphus Mill. As the root stock or the intermediate stock, has the advantages of close genetic relationship, good grafting affinity, strong environmental suitability, good quality maintenance, resistance acquisition of any jujube variety, low cost, high prevention effect, strong operation practicability, easy popularization and promotion and the like, can directly meet the current industrial requirement, and has great significance.

Description

technical field [0001] The invention relates to a method for controlling jujube madness by using an anti-mad rootstock, and belongs to the technical field of jujube seedling cultivation and disease prevention and control. Background technique [0002] Jujube (Zizyphus jujube) is native to my country and is one of the important dried fruit and characteristic economic tree species in China. Jujube madness is a disease caused by the systemic infection of phytoplasmas, which occurs to varying degrees in jujube producing areas at home and abroad, causing huge economic losses to the jujube industry, and is a kind of destruction in jujube production. sexual disease. Phytoplasmas are mainly transmitted by leafhoppers (Hishimonoides sp.), and exist in the parenchyma cells of the phloem after invading the host, and move up and down in the body with the seasons. Small trees will die within 1 to 2 years, and large trees will die gradually within 3 to 6 years. [0003] Clearing diseas...

AI Technical Summary

Problems solved by technology

Although the trunk injection of drugs such as tetracycline or oxytetracycline has a certain curative effect, the symptoms will reappear soon after losing the drug, and the source of the disease cannot be eliminated

Anti-crazy varieties are also recommended, but it is difficult to meet the market's demand for quality and variety diversity

Removing diseased trees to eliminate the source of the disease, timely spraying insecticides to kill the media are also important measures, but it is difficult to fundamentally control the serious harm of jujube madness to the industry
