Problems solved by technology

The disease mainly harms walnut fruit. Radial chlorotic spots appear on the navel of walnut fruit in the early stage, and then dark brown radial lesions form, causing the fruit to split in advance and the kernel to shrink, which seriously affects the yield and quality of walnut.

Embodiment 1

[0035] A method for preventing and treating walnut virus disease:

[0036] (1) At the beginning of March, whitewash the trunk, trim the tree body, remove litter and fallen leaves, take it out of the orchard for landfill or incineration, and then spray 40% MnZn 800 times diluted solution to disinfect the tree body.

[0037] (2) Soil micro-ecological regulation during the germination period of the tree body: in the early to mid-April period, during the germination period of the fruit tree, dig a 40cm wide and 30cm deep annular ditch at a distance of 50cm from the trunk under the canopy, and reduce the bacterial content to 10 billion spores / The 350-fold dilution of Bacillus amyloliquefaciens GLD191 inoculum of g is evenly poured into the annular ditch.

[0038] (3) Disease prevention and pest control during the rapid growth period of walnut fruit: from the beginning of May to the first ten days of June, spray 0.5% amino oligosaccharin 1000 times solution on the leaves, and spray...

Abstract

The invention discloses a method for preventing and treating walnut virus diseases, belonging to the technical field of agriculture. The method for preventing and treating walnut virus diseases comprises the following steps: irrigating a biological agent in a fruit tree germination period; spraying a disease-resistant agent and an imidacloprid buprofezin suspending agent with a concentration of 18% in a rapid growth period of walnut fruit to kill insects; spraying a mixed pesticide solution in a walnut kernel hardening period, and conducting prevention and treatment on walnut rot diseases; and irrigating a biological agent and spraying a macleaya cordata extract-veratrine aqueous solution with a concentration of 1% again in a walnut kernel filling period, and performing conventional field management in the period. According to the method, occurrence of walnut virus diseases is effectively controlled, the purposes of enhancing tree vigor and improving the yield and quality of walnuts are achieved, potential threats of the walnut virus diseases to the walnut industry are eliminated, and sustainable development of the walnut industry is ensured.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a method for preventing and treating walnut virus disease. Background technique [0002] Walnut (Juglans regia L.) is the largest fruit tree in Xinjiang, with a planting area of ​​more than 7 million mu, accounting for about one-third of the total forest and fruit area in Xinjiang. It is mainly distributed in Hotan, Kashgar and Aksu in Xinjiang. It has become one of the important pillar industries of regional economic development in Xinjiang. In 2017, a new walnut disease occurred in the walnut planting area of ​​Wensu County, Aksu Prefecture, and the affected area was about 450 hectares. The disease mainly harms walnut fruit. Radial chlorotic spots appear on the navel of walnut fruit in the early stage, and then dark brown radial lesions form, causing the fruit to split in advance and the kernel to shrink, which seriously affects the yield and quality of walnut. [0003]...
