Embodiment 1

[0017] A method for preventing and treating watermelon wilt, comprising the following steps:

[0018] (1) First disinfect the watermelon seeds, soak them for 5-8 minutes, the disinfectant used contains potassium permanganate with a mass fraction of 10%, hydrogen peroxide with a mass fraction of 1.5%, and the rest is ethanol solution, and the solution is disinfected Afterwards, soak in hot water at 45°C for 12 hours, and then bury them in wet sand for germination. The materials used in the seed treatment process are all irradiated under ultraviolet light for 50 seconds;

[0019] (2) The germinated seeds are transferred to the seedbed for cultivation, and the seedbed is sprayed every 2 days with the prepared plant sterilizing liquid, which consists of: mugwort leaves, aloe vera, ginkgo leaves, white tea, dandelion, toad grass, and Viola chinensis Prepared, do not contact rainwater during the cultivation process, use sterile water to dilute the nutrient solution for irrigation, t...

Embodiment 2

[0025] A method for preventing and treating watermelon wilt, comprising the following steps:

[0026] (1) Firstly, disinfect the watermelon seeds and soak them for 6 minutes. The disinfectant used contains potassium permanganate with a mass fraction of 12%, hydrogen peroxide with a mass fraction of 1.8%, and the rest is ethanol solution. Soak in hot water at 48°C for 13 hours, and then bury in wet sand for germination. The materials used in the seed treatment process are irradiated with ultraviolet light for 55 seconds;

[0027] (2) The germinated seeds are transferred to the seedbed for cultivation, and the seedbed is sprayed every 2 days with the prepared plant sterilizing liquid, which consists of: mugwort leaves, aloe vera, ginkgo leaves, white tea, dandelion, toad grass, and Viola chinensis Prepared, do not contact rainwater during the cultivation process, use sterile water to dilute the nutrient solution for irrigation, the dilution ratio is 48:1, increase the temperatur...

Embodiment 3

[0033] A method for preventing and treating watermelon wilt, comprising the following steps:

[0034](1) Firstly, disinfect the watermelon seeds and soak them for 8 minutes. The disinfectant used contains potassium permanganate with a mass fraction of 15%, hydrogen peroxide with a mass fraction of 2.0%, and the rest is ethanol solution. Soak in hot water at 50°C for 15 hours, and then bury them in wet sand for germination. The materials used in the seed treatment process are irradiated with ultraviolet light for 60 seconds;

[0035] (2) The germinated seeds are transferred to the seedbed for cultivation, and the seedbed is sprayed with the prepared plant sterilizing liquid every 3 days. The plant sterilizing liquid is composed of: mugwort leaves, aloe vera, ginkgo leaves, white tea, dandelion, toad grass, Viola chinensis Prepared, do not contact rainwater during the cultivation process, use sterile water to dilute the nutrient solution for irrigation, the dilution ratio is 50:...

Abstract

The invention relates to the technical field of watermelon plantation and discloses a method for preventing and controlling watermelon fusarium wilt. Firstly, seeds are disinfected to eliminate the latency of pathogens, and then, watermelons are promoted to grow robustly on an aspect of a planting management way, so that the disease resistance is improved; and due to the use of a chemical agent, the synthesis of ergosterol serving as a pathogen of watermelon fusarium wilt can be inhibited, cell membranes can be destroyed, morphological and physiological changes can be induced, and finally, cell death is caused, in addition, the synthesis of wilting toxin serving as a pathogen of watermelon fusarium wilt can be inhibited, the pathogenicity of the pathogen of watermelon fusarium wilt is effectively reduced, meanwhile, the root activity of watermelons can be improved, the growth of the watermelons can be accelerated, the microorganism environment of soil around the watermelons can be improved, the self resistance can be improved, and a self disease-resistant gene can be gradually formed.

Description

technical field [0001] The invention belongs to the technical field of watermelon planting, and in particular relates to a method for preventing and controlling watermelon wilt. Background technique [0002] Watermelon, an annual vine; stems and branches are thick, with obvious ribs. The tendrils are thick, pubescent, with thick petioles and densely pilose; the leaves are papery, triangular-ovate in outline, with white-green, two short bristles, heart-shaped at the base of the leaves. Monoecious. Both male and female flowers are solitary in leaf axils. The pedicel of the male flower is 3-4 cm long, densely covered with yellow-brown villous hairs; the calyx tube is broadly bell-shaped; the corolla is light yellow; the stamens are nearly free, the filaments are short, and the cells are curved. Female flowers: calyx and corolla same as male flowers; ovary ovate, stigma reniform. The fruit is large, nearly spherical or oval, fleshy, juicy, smooth, with various colors and pat...
