Embodiment Construction
[0017] The present invention will be further described below in conjunction with specific examples.
[0018] A method for controlling watermelon continuous cropping diseases by inducing natural factors, comprising the steps of:
[0019] Step 1. Use organic matter to fully fertilize the soil before watermelon planting. Crop stalks, edible fungus residues, cow dung, sheep dung, cake fertilizer and other materials can be used. After fertilization, the soil is loose and air-permeable, and the organic matter content of the soil is controlled to exceed 4%. Among them, fully fertilizing the soil with organic matter is to apply crop straw, edible fungus residue, cow dung, sheep manure, cake fertilizer, etc. to the field after fully decomposing and fermenting, and plow the plow layer soil (20-30cm), after 2 weeks Afterwards, the soil organic matter content was measured, and the organic matter content was controlled to exceed 4%.
[0020] Step 2. The first batch of watermelon is plant...

The invention discloses a method for controlling watermelon continuous cropping diseases by inducing natural factors. The method comprises the following step that firstly, soil is fully fertilized before planting; secondly, a first crop of watermelons are planted in a common planting mode; thirdly, after the first crop of watermelons are harvested, watermelon vines are cut off along the ground, fields are cleaned, the fields are not tilled, and watermelons are directly sown on original planting lines; fourthly, thinning is not conducted after seedling emergence of a second crop of watermelons, and seedlings freely grow; fifthly, about three months after sowing of the second crop of watermelons, watermelon vines are cut off along the ground again, and a third crop of watermelons are planted in a planting management mode of the second crop of watermelons; sixthly, three crops of watermelons are planted in a year under the conditions of greenhouse facilities. After planting of the three crops of watermelons is completed, inhibition factors of the watermelon continuous cropping diseases in soil can be induced. By utilizing the method, the watermelon continuous cropping diseases basically do not happen to watermelons planted within three continuous years after one year of induction, and the stable yield of the watermelons is maintained.
Description
technical field [0001] The invention relates to a method for preventing and controlling plant diseases, in particular to a method for controlling watermelon continuous cropping diseases by inducing natural factors, and belongs to the technical field of watermelon disease prevention and control. Background technique [0002] Fusarium wilt, a soil-borne disease of watermelon, is a disease that seriously threatens watermelon production. The pathogen mainly overwinters in the soil and can survive in the soil for more than 10 years. Invasion of external wounds. In addition, the long-term continuous cropping of watermelon leads to the lack of certain nutrient elements in the soil and the accumulation of plant root exudates and residues, resulting in self-poisoning, affecting the growth of plants, and continuous cropping obstacles. [0003] Therefore, in the process of watermelon planting, it is necessary to adopt corresponding technical means to control watermelon continuous cr...
