Problems solved by technology

However, for the situation of not changing the species of aquatic plants and continuous cropping, there is no technical plan to ensure that the rotten diseases of aquatic plants do not occur. After the fungicides have been used to kill the rotten bacteria, the chances of the rotten bacteria coming back after the fungicide toxicity fades are very high. Big
Moreover, the use of fungicides for years will cause pathogenic bacteria to develop drug resistance and drug resistance, resulting in a decline in the bactericidal effect year by year.

Embodiment 1

[0022] Drain the water from the aquatic plant soil. The bamboo vinegar liquid of 1 weight part is diluted with 500 times of pure water, mixed and applied to the soil of aquatic plants, and 1 kilogram of diluted and mixed bamboo vinegar liquid is used per mu. After the bamboo vinegar solution was applied for 24 hours, the Chinese herbal medicine composition that was formed into 80 meshes was ground after mixing 1 weight part of Herb Lemongrass, 1 weight part of Chaku and 1 weight part of Semen Cassiae, and put the Chinese herbal medicine composition into the soil, Use 5000 grams of Chinese herbal medicine composition per mu to turn the soil and mix the Chinese herbal medicine composition with the soil on the soil surface. After the Chinese herbal medicine composition is put into the soil for 48 hours, quicklime is put into the soil, using 500 grams per mu, the soil is turned over to mix the quicklime with the soil on the soil surface, and the disinfection is completed after 48 ...

Embodiment 2

[0024] Drain the water from the aquatic plant soil. The bamboo vinegar solution of 1 weight part is diluted with 1000 times of pure water, mixed and applied to the soil of aquatic plants, and 10 kilograms of the diluted and mixed bamboo vinegar solution is used per mu. After the bamboo vinegar solution was applied for 72 hours, the Chinese herbal medicine composition formed by grinding into 400 meshes after mixing 1 weight part of lingxiangcao, 1 weight part of Chaku, and 1 weight part of Semen Cassiae, and mixing the Chinese herbal medicine composition with the same weight part of Put the green brick powder into the soil, use 2000 grams of Chinese herbal medicine composition and 2000 grams of green brick powder per mu, turn over the soil to mix the Chinese herbal medicine composition, green brick powder and the soil on the soil surface. Put the Chinese herbal medicine composition and green brick powder into the soil for 72 hours, put quicklime into the soil, use 5000 grams pe...

Embodiment 3

[0026] Drain the water from the aquatic plant soil. The bamboo vinegar liquid of 1 weight part is diluted with 700 times of pure water, mixed and applied in the soil of aquatic plants, and 5 kg of diluted and mixed bamboo vinegar liquid is used per mu. After the bamboo vinegar solution was applied for 48 hours, the Chinese herbal medicine composition that was formed into 240 meshes was ground after mixing 1 weight part of Herbal Herbs, 1 weight part of Chaku, and 1 weight part of Semen Cassiae, and the Chinese herbal medicine composition was put into the soil, Use 3300 grams of Chinese herbal medicine composition per mu to turn the soil and mix the Chinese herbal medicine composition with the soil on the soil surface. After the Chinese herbal medicine composition is put into the soil for 64 hours, quicklime is put into the soil, using 2500 grams per mu, the soil is turned over to mix the quicklime with the soil on the soil surface, and the disinfection is completed after 64 ho...

Abstract

The invention provides a method for soil disinfection of an aquatic plant. The aquatic plant is an economical crop with very high nutritive values, but rot diseases of the aquatic plant are often caused by continuous cropping. The rot diseases of the aquatic plant mainly happen at underground stems and roots of the aquatic plant and cause yellowing, browning and rot to aboveground leaves, and even cause blight to aboveground parts. The underground stem of a diseased plant generates mycelial and pink sticky substances, and part of the underground stem shows water-logging type specks. Finally, lotus whips, diseased stems and diseased roots show purple brown specks, the inside of the lotus whips is browned, the diseased stems shrink longitudinally, and lotus roots are necrotized. The first part infected by rot diseases of the aquatic plant is in an aquatic environment, so that the symptoms of the disease are difficult to discover and are difficult to control. Therefore, the method provided by the invention adopts a manner of combined application of a bamboo vinegar solution, Chinese medicinal herbs and quicklime, and can be used for effectively killing pathogenic bacteria in the aquatic plants, and eliminating pathogenic causes of the aquatic plant.

Description

technical field [0001] The invention relates to the technical field of soil disinfection, in particular to a soil disinfection method for aquatic plants. Background technique [0002] Aquatic plants, such as lotus root, are economical crops with high nutritional value, but continuous cropping often causes aquatic plant rot. Aquatic plant rot mainly occurs in the underground stems and roots of aquatic plants, causing the aboveground leaves to turn yellow, brown and rot, and even cause the aboveground parts to wither. Hyphae and pink viscous substances appeared on the underground stems of the diseased plants, and some of them showed water-soaked lesions. Finally, the lotus whip, the diseased stem and the damaged part of the root all showed purple-brown lesions, the interior of the lotus whip was brown, the diseased stem shrank longitudinally, and the lotus root was necrotic. The first infection site of aquatic plant rot disease is in the aquatic environment, and the disease ...
