Problems solved by technology

[0004] The object of the present invention is to provide a method for preventing and treating root-knot nematode disease in solar greenhouses, which can effectively control the occurrence and harm of root-knot nematode disease, ensure the production safety of greenhouse vegetables, and solve the problem of low quality agricultural products caused by excessive use of chemical pesticides. Compared with root-knot nematode control measures, it not only has low cost, high control efficiency, simple operation and no pollution, but also effectively slows down the resistance of nematodes, ensuring the quality of agricultural products, the safety of operators and the environment

Embodiment 1

[0022] From July 15th to August 11th, 2010, smothering was carried out during the period when the greenhouse was closed. Under the condition that the shed film used the old shed film used in the previous stubble and the straw curtain was not covered at night, a total of 3 treatments were set up and repeated three times. A total of 9 plots with an area of ​​40m 2 .

[0023] Treatment 1: Deep plow the soil first, and then 400kg / 667m of straw 2 After application, use a rotary tiller to mix it with the soil, then cover it with plastic film, then fill it with sufficient water, and seal the shed for 25 days.

[0024] Treatment 2: Dig the soil deeply first, then cover with mulch without applying straw, then fill with sufficient water, and seal the shed for 25 days.

[0025] Treatment 3: blank control, deep plowing of the soil first, no application of straw and no mulch film, only enough water, and airtight greenhouse for 25 days.

Embodiment 2

[0037] In 2011, the smothering conditions were optimized and tested again. During the period from July 20 to August 13, 2011, when the greenhouse was closed, three treatments were set up under the condition that the film was replaced, the straw curtains were covered from 19:00 to 8:00 the next day, and the straw curtains were drawn at 8:00 am. Three repetitions, a total of 9 plots, with a plot area of ​​70.8m 2 .

[0038] Treatment 1: Deep plow the soil first, and then 400kg / 667m of straw 2 After application, use a rotary tiller to mix it with the soil, then cover it with plastic film, then fill it with sufficient water, and seal the shed for 25 days.

[0039] Treatment 2: Dig the soil deeply first, then cover with mulch without applying straw, then fill with sufficient water, and seal the shed for 25 days.

[0040] Treatment 3: Blank control, no straw application, no mulching film, only enough water, airtight greenhouse, last 25 days

Abstract

The invention discloses a method for preventing solar greenhouse root-knot nematode disease. The method comprises the steps of replacing an old greenhouse membrane with a new greenhouse membrane in a greenhouse-resting period during a high-temperature season, conducting deep ploughing on soil in the greenhouse for 30-50 cm and afterwards conducting levelling, and forming multiple parallel water-conducting ditches on the soil; using plastic mulching film to cover the soil in the greenhouse, irrigating the soil with sufficient water from water-irrigating holes of the water-conducting ditches , and afterwards conducting smothering in the sealed greenhouse, wherein in the smothering period, the greenhouse is covered with a greenhouse mat from every dawn to next morning, and the greenhouse mat is drawn back from the morning to the dawn; conducting continuous smothering for 15 d-25 d, then opening a wind opening of the greenhouse and conducting ventilation for 5-7 days, and uncovering the mulching film so that sowing can be conducted. By means of the method for preventing the solar greenhouse root-knot nematode disease, the occurrence of danger of root-knot nematode can be effectively controlled, the safe production of greenhouse vegetables is guaranteed, and the problem of inferior quality of agricultural products caused by excessive use of chemical pesticides is solved.

Description

technical field [0001] The invention belongs to the technical field of prevention and control of agricultural diseases and insect pests, and in particular relates to a method for preventing and controlling root-knot nematode disease in a solar greenhouse. Background technique [0002] Root-knot nematode root-knot nematode is the most serious soil-borne disease of greenhouse vegetables, and the output of greenhouse vegetables can be reduced by up to 50%, and some greenhouse vegetables even become extinct. The prevention and treatment of this disease mainly uses thiazophos, carbofuran, methinamid and other medium and high-toxicity pesticides at present (see references for details: Guojin, Xu Meirong, 5% thiazophos granules to control eggplant root-knot nematode in greenhouses, "China Fruits and Vegetables, 2009 (7): 22-23; Gan Jiyuan, Tang Junling, field chemical control experiment of watermelon root-knot nematode in solar greenhouse, "Plant Doctor", 2009 (5) 39-40) not only t...
