Embodiment 1

[0025] A method for preventing and controlling notoginseng nematode disease, comprising the following steps:

[0026] (1) Soil improvement: select nematicidal plants: aerial parts of Artemisia annua, Eupatorium adenophorum and Echinopsis (avoid the aerial parts of nematicidal plants harvested during the flowering and fruiting period), and mix them in a mass ratio of 2:2:1 Carry out decomposing for 30 days, deeply plow the soil by 40-45cm, mix nematicidal plants, biochar, and organic fertilizer into the soil at a mass ratio of 2:1.5:1, and apply the total amount of nematicidal plants, biochar, and organic fertilizer per mu 1800-2000kg, cover with film for 45 days, remove the film and dry for 10 days before planting Panax notoginseng seedlings;

[0027] (2) Plant coverage: directly and evenly lay the aboveground parts of Artemisia annua and thistle on the planting surface of Panax notoginseng, and then lay pine hairs, and the density of nematode-killing plants is 2kg / m 2 Laying...

Abstract

The invention relates to the technical field of green disease prevention and control of medicinal plants, and particularly discloses a method for preventing and controlling nematode disease of panax notoginseng. The method comprises the following steps that nematode-killing plants of overground parts of artemisia abrotanoides, eupatorium adenophorum and circium japonicum are selected, mixing and decomposing are carried out, the mixed and decomposed nematode-killing plants, biochar and organic fertilizer are mixed according to a mass ratio of 2: 1.5: 1, and then the mixture is mixed into soil; the overground parts of the artemisia abrotanoides and the circium japonicum are uniformly mixed and paved on the panax notoginseng planting moisture surface, and then pine leaves are paved; and the overground parts of the artemisia abrotanoides and the circium japonicum are crushed to 20-30 meshes, and correspondingly and uniformly spread to the panax notoginseng planting moisture surface in the sixth month, the eighth month and tenth month of panax notoginseng planting. According to the technical scheme, the nematode disease inhibition rate of panax notoginseng reaches up to 90%-92%, the use amount of chemical agents and pesticides is reduced by 60%, and ecological planting and green disease prevention and control of panax notoginseng are achieved.

Description

technical field [0001] The invention relates to the technical field of prevention and control of green diseases of medicinal plants, in particular to a method for prevention and control of notoginseng nematode disease. Background technique [0002] Sanqi (Panax notoginseng (Burk.) F.H.Chen) is a plant of the genus Ginseng in the family Araliaceae, and is a traditional precious Chinese medicinal material well-known at home and abroad in my country. However, nematode disease has developed into the main obstacle factor of the Panax notoginseng industry. The nematode disease mainly harms the medicinal parts of Panax notoginseng, which can cause root galls, clubroot, thick and short roots, root cortex swelling and root rot in the roots, and cause plant damage. wilting. At the same time, in addition to direct damage to the roots, nematodes can also spread fungi, bacteria, viruses, etc., resulting in compound infections and complex diseases, such as nematodes and wilting fungi Fus...
