Problems solved by technology

However, due to suitable climate and soil conditions, osmanthus seedlings are often infested by diseases and insect pests during planting, especially root-knot nematode, the incidence rate can reach more than 90%. Therefore, the prevention and treatment of osmanthus seedling root-knot nematode must be done enough attention
The current treatment methods are mainly to kill root-knot nematodes by spraying insecticides. This method is not very effective, and if things go on like this, root-knot nematodes have undergone genetic mutations to become resistant to insecticides. Some The growers do not hesitate to increase the amount of use, but there is no obvious effect, and it also causes great chemical pesticide pollution

Embodiment 1

[0014] A method for controlling root-knot nematode of osmanthus osmanthus seedlings, comprising the following steps:

[0015] (1) Dig up the 1-2-year-old osmanthus seedlings by their roots, clean the soil on the roots, and dry them to keep the water content in the roots at 40-50%, which can ensure the survival of osmanthus seedlings and inhibit root formation For the growth and reproduction of nematodes, refrigerate the roots of the saplings at 3-5°C for 5 hours. This low temperature environment can kill most of the root-knot nematodes and their eggs, and then quickly use reed leaves to fumigate for 8 minutes. After fumigation, ensure All the root-knot nematodes and their eggs were killed. At the same time, the pentosan and coixin in the reed leaves can regulate the root cells of the sweet-scented osmanthus seedlings and promote their root development. After cooling at room temperature, spray with clean water;

[0016] (2) Prepare an insect repellant, the ingredients of which ...

Embodiment 2

[0022] A method for controlling root-knot nematode of osmanthus osmanthus seedlings, comprising the following steps:

[0023] (1) Dig up the 1-2-year-old osmanthus seedlings by their roots, clean the soil on the roots, and dry them to keep the water content in the roots at 40-50%, which can ensure the survival of osmanthus seedlings and inhibit root formation For the growth and reproduction of nematodes, refrigerate the roots of the saplings at 3-5°C for 6 hours. This low temperature environment can kill most of the root-knot nematodes and their eggs, and then quickly use reed leaves to fumigate for 10 minutes. After fumigation, ensure All the root-knot nematodes and their eggs were killed. At the same time, the pentosan and coixin in the reed leaves can regulate the root cells of the sweet-scented osmanthus seedlings and promote their root development. After cooling at room temperature, spray with clean water;

Abstract

The invention relates to the field of competitive nursery stock planting, in particular to a method for preventing and treating eloidogyne disease of sweet osmanthus seedling. In raising seedlings by cuting of the sweet osmanthus, morbidity of the meloidogyne disease is often up to 90% or above, the meloidogyne disease harms the growth of the sweet osmanthus, and therefore, by means of a combination of a physical method and a chemical method, the meloidogyne is killed fundamentally, so as to reduce the morbidity of the meloidogyne disease to 1%. The physical method is mainly to treat the root of the sweet osmanthus seedling between by sudden change between high-temperature and low-temperature to achieve the effect of killing parasites, while the chemical method is to spray the planting soil by preparing an insect repellent to destroy the growth and development environment of the meloidogyne. The insect repellent is prepared by natural plants, contains no pesticides, does not cause chemical pollution, and at the same time does not make the meloidogyne resistant to the insect repellent.

Description

technical field [0001] The invention relates to the field of high-quality seedling planting, in particular to a method for preventing and treating root-knot nematode disease of sweet-scented osmanthus seedlings. Background technique [0002] Osmanthus fragrans is one of the ten famous traditional Chinese flowers. It is an excellent garden tree species that integrates greening, landscaping and fragrance, and has both ornamental and practical features. Especially in the mid-autumn season, when the osmanthus clusters are in full bloom, and when the night is quiet and round, you can enjoy the osmanthus with wine, and the fragrance is fragrant, refreshing. In ancient Chinese poems chanting flowers, the number of chanting osmanthus is also quite considerable. Just be deeply liked by the Chinese since ancient times, be regarded as traditional famous flower. It is now widely planted in the Huaihe River Basin and the areas south of it. Its suitable habitat can reach the lower reach...
