Embodiment Construction

[0019] The present invention provides many applicable inventive concepts that can be embodied in numerous specific contexts. The specific examples described in the following embodiments of the present invention are only used as illustrations of specific embodiments of the present invention, and are not intended to limit the scope of the present invention.

[0020] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] The invention provides the use of horseradish as a fumigant in soil disinfection of Panax notoginseng continuous cropping. Horseradish refers to a class of secondary metabolites extracted from horseradish Armoracia rusticana (Lam.) Gaertn., B.Mey.etScherb. and other cruciferous plants, all containing -N=C= S active group, which can be volatile at room temperature and looks like an oily liquid. The application of horseradish as a fumigant in the disinfection of Panax notoginseng cont...

Abstract

The invention discloses a purpose of allyl isothiocyanate for disinfection of panax notoginseng continuous cropping soil. Disinfection of the panax notoginseng continuous cropping soil includes the following steps that the soil is processed, the soil in which panax notoginseng is planted is deeply harrowed, aired and ridged, the absolute water content of the soil is adjusted, and the soil is kept moist; fumigant is sprayed, a dilute aqueous solution of the allyl isothiocyanate is evenly sprayed on the processed soil; sealed fumigation is conducted, and the ground surface is sealed for 7-15 days through a transparent film. The allyl isothiocyanate is used for fumigation disinfection of the panax notoginseng continuous cropping soil, the good nematode killing and bacterium resistance activity is achieved, meanwhile, the allyl isothiocyanate is from plants and belongs to a environment-friendly compound, and pollution to the environment is avoided.

Description

technical field [0001] The invention relates to the field of agricultural plant protection, in particular to a use of horseradish for soil disinfection of Panax notoginseng cropping. Background technique [0002] The obstacle of continuous cropping of Panax notoginseng is particularly prominent, and its mechanism is very complex, including soil-borne diseases, autotoxicity, nutrient balance, growth and decline of soil microorganisms and other factors. Soil-borne diseases are the primary limiting factors of Panax notoginseng continuous cropping obstacles. The current research shows that Panax notoginseng root rot is caused by the complex infection of more than ten kinds of pathogens such as underground pests, root-knot nematodes, fungi Fusarium, bacteria Erwinia and so on. [0003] Traditional control methods include disease-resistant breeding, grafting, crop rotation, deep plowing, soil replacement, and root irrigation with chemical pesticides. However, due to limited land...
