Aquatic plant soil disinfecting method

Abstract

The invention provides an aquatic plant soil disinfecting method. Aquatic plants are crops with high economic efficiency and high nutritional value, but the aquatic plants always have a rot disease due to continuous cropping. Aquatic plant rot disease mainly occurs on underground stems and roots, and causes upper leaf yellowing, browning, rotting, and even withering of the ground plant. The underground stems and roots of the disease plant generate hypha and pink glutinous substances, and a part of underground stems and roots generate water-immersion scabs. Finally, lotus whip, the disease stems and the roots generate purple brown scabs, the inner part of the lotus whip is brown, the disease stems longitudinally shrink, and the lotus roots necrotize. A first rot disease site of the aquatic plant in the aquatic environment is difficult to detect and hard to control. Therefore, according to the aquatic plan soil disinfecting method, bamboo vinegar, Chinese herbal medicines and quicklime are combined to effectively kill pathogens in the aquatic plants, and pathogenic reason of the aquatic plants can be eradicated.

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 ...

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.
