Embodiment Construction

[0016] A kind of cultivation method of preventing spring cabbage soft rot of the present invention comprises the steps:

[0017] (1) Selection of disease-resistant varieties Select high-quality varieties with high resistance to soft rot to enhance the disease resistance of cabbage itself from the source.

[0018] (2) Site selection and fertilization and pesticide application In the first ten days of March, select a plot with fertile land and non-cruciferous crops in the past, apply enough base fertilizer, and at the same time sprinkle insecticides and fungicides, deep plow and rake in the sun to eliminate soil Medium pathogenic bacteria and insect eggs, reduce the number of initial pathogenic bacteria and insect eggs in the soil.

[0019] (3) Ridging and drip irrigation pipes In mid-March, ridges were formed along the north-south direction of the extended land, and the ridges were in the shape of trapezoids, which is convenient for the placement of drip irrigation pipes. The ...

Abstract

The invention discloses a cultivation method for preventing soft rot of spring Chinese cabbage. The cultivation method comprises the following steps: selecting a disease-resistant variety, selecting land for applying a fertilizer and a pesticide, carrying out ridging and distributing drip irrigation pipes, carrying out plug seedling cultivation, carrying out management in a seedling period, carrying out field planting, carrying out insect prevention net covering, carrying out field management and carrying out harvesting. Through the adoption of the measures, disease resistance of Chinese cabbage is enhanced, the number of pathogenic bacteria and eggs in the soil is reduced, the probability that pathogenic bacteria are transmitted through a water source is avoided, the seed utilization rateand seedling breeding efficiency are improved, probability of invasion by pathogenic bacteria in a seedling stage is reduced, activity frequency of workers in fields is reduced, and probability of damage caused by humans to the Chinese cabbage is reduced. The morbidity is controlled to be 1% or below of morbidity of current conventional fields.

Description

technical field [0001] The invention relates to the field of vegetable disease prevention and control, in particular to a cultivation method for preventing and treating spring cabbage soft rot. Background technique [0002] The spring cultivation of Chinese cabbage is an important stubble to achieve a balanced supply of Chinese cabbage annual production. Spring cabbage is an off-season cultivation of Chinese cabbage. During the cultivation process, as the temperature rises, the incidence of soft rot becomes more and more serious. At present, the average incidence rate in the field is about 20%, and the diseased plant rate can reach 100% in the worst case. . Soft rot is a bacterial disease and one of the three major diseases of Chinese cabbage. Soft rot has always been a key factor restricting the large-scale development of spring cabbage, and has a great impact on the growth quality of spring cabbage and the economic benefits of vegetable farmers. In the early stage of th...
