Abstract

The invention discloses a traditional Chinese medicine composition used for preventing and treating pest and disease damage of greenhouse water convolvulus. The traditional Chinese medicine composition is prepared from the following raw materials by weight: 18 to 22 parts of Semen Ulmus macrocarpa, 16 to 20 parts of grand torreya seed, 3 to 5 parts of Omphalia lapidescens, 4 to 6 parts of quisqualis, 5 to 7 parts of melia root bark, 3 to 5 parts of Ferula asafoetida, 6 to 10 parts of Cyrtomium fortunei, 8 to 12 parts of hydnocarpus seeds, 9 to 11 parts of Tripterygium wilfordii, 5 to 15 parts of jequirity bean, 8 to 14 parts of Radix euphorbiae, 3 to 5 parts of sulfur, 2 to 4 parts of common cnidium fruit and 1 to 3 parts of golden larch bark. The traditional Chinese medicine composition used for preventing and treating pest and disease damage of greenhouse water convolvulus can reduce both pest and disease damage and harm to tender shoots and tender leaves of crops in a greenhouse; and effective components and special smell of the traditional Chinese medicine composition can last for a long time on leaves and in soil, so time for prevention and treatment of pest and disease damage is greatly prolonged.

Description

technical field [0001] The invention relates to a traditional Chinese medicine composition and a preparation method thereof for controlling pests and diseases of water spinach in greenhouses. Background technique [0002] Greenhouse vegetables refer to the vegetables grown by covering plastic films on the greenhouses. It is one of the effective means to increase farmers' income by artificially creating a suitable ecological environment, adjusting vegetable production seasons, adjusting market demand, and promoting high-quality and high-yield vegetables. Due to the high temperature and humidity in the greenhouse, weak light, and slow air flow, it is almost not directly affected by wind and rain from the outside. Vegetables grow vigorously and their buds are tender, and vegetables are vulnerable to diseases and insect pests. Traditional chemical control methods usually have strong drug effects, which are easy to cause damage to the tender shoots and leaves of vegetables, and t...
