Problems solved by technology

[0004] Although the control of chemical pesticides has a certain effect, the pollution is serious, and with long-term application, many bacteria develop resistance, leading to an increase in the disease
At the same time, due to the large amount of pesticide application, the crops have phytotoxicity and poisoning, which seriously affects agricultural production. What is more serious is that there are a large number of toxic substances remaining in food, vegetables, fruits and all agricultural products. Animals are extremely harmful, and human and animal poisoning often occur, directly threatening human health

Embodiment 1

[0029] A natural plant fungicide for preventing and controlling dendrobium diseases and insect pests is prepared from the following raw materials in parts by weight: 20 parts of lantana, 20 parts of camellia oleifera cake, 10 parts of neem leaves, 5 parts of Polygonum oleifera and 5 parts of Moringa oleifera leaves. Mince lantana, neem leaves, Polygonum oleifera and Moringa leaves; crush the camellia oleifera cake and pass through a 100-mesh sieve to obtain the fine powder of camellia oleifera cake; put the raw materials processed in the previous two steps into a round bottom flask, Add 1 times the ethanol solution to the total weight ratio, soak for 18 hours, then add 2 times the water according to the total weight ratio of the raw materials, then heat to 80-90°C, and carry out heating and reflux extraction for 2 hours; after the extraction is completed, filter and take The filtrate is diluted 5 times to obtain the desired natural plant fungicide.

Embodiment 2

[0031] A natural plant fungicide for the prevention and control of dendrobium diseases and insect pests, prepared from the following raw materials in parts by weight: each raw material is composed of 30 parts of lantana, 25 parts of oil tea cake, 14 parts of neem leaves, 7 parts of Polygonum 8 parts, Moringa leaf. Chop lantana, neem leaves, Polygonum oleifera and Moringa leaves; crush the camellia oleifera cake and pass through a 120-mesh sieve to obtain the fine powder of camellia oleifera cake; put the raw materials processed in the previous two steps into a round bottom flask, press the Add 1.2 times the ethanol solution to the total weight ratio, soak for 20 hours, then add 4 times the water according to the total weight ratio of the raw materials, then heat to 80-90°C, and carry out heating and reflux extraction for 3 hours; after the extraction is completed, filter and take The filtrate is diluted 6 times to obtain the desired natural plant fungicide.

Embodiment 3

[0033] A natural plant fungicide for the prevention and control of dendrobium diseases and insect pests, prepared from the following raw materials in parts by weight: 40 parts of lantana, 30 parts of oil tea cake, 15 parts of neem leaves, 10 parts of Polygonum 10 parts, Moringa leaf. Chop lantana, neem leaves, Polygonum oleifera, and Moringa leaves; crush the camellia oleifera cake and pass through a 150-mesh sieve to obtain the fine powder of camellia oleifera cake; put the raw materials processed in the previous two steps into a round bottom flask, and press the Add 1-2 times the ethanol solution to the total weight ratio, soak for 22 hours, then add 3 times the water according to the total weight ratio of the raw materials, and then heat to 80-90°C for heating and reflux extraction, the extraction time is 2.5 hours; after the extraction is completed , filter to get the filtrate, dilute 8 times to get the desired natural plant fungicide.

Abstract

The invention relates to the technical field of agriculture, and concretely relates to a natural plant bactericide for controlling dendrobium insect diseases. The bactericide is prepared from, by weight, 20-60 parts of Lantana camara, 20-40 parts of oil tea cakes, 10-20 parts of chinaberry leaf, 5-15 parts of Polygonum glabrum and 5-15 parts of Moringa tree leaf through heating and refluxing extraction and through dilution. The natural plant bactericide prepared in the invention has the advantages of substantial control effect on dendrobium insect diseases, no need of chemical pesticide spraying in the plantation process, and obvious reduction of the incidence rate of insect diseases. Dendrobium produced by using the natural plant bactericide has no pesticides, no hormones or no chemical drug pollution, is pure natural, and has excellent quality, no peculiar smell and improved eating safety. Raw materials selected in the invention have few kinds, and a preparation method of the natural plant bactericide is simple, and is easy to grasp, promote and apply.

Description

【Technical field】 [0001] The invention belongs to the technical field of agriculture, and in particular relates to a natural plant fungicide used for preventing and controlling dendrobium disease and insect pests. 【Background technique】 [0002] Dendrobium is listed as "the first of the nine immortal grasses in China", and has been listed as a royal tribute since the Tang and Song Dynasties. Dendrobium is the first choice for nourishing yin, preventing tumors, and enhancing the body's immunity. It is the best Chinese herbal medicine for promoting body fluid and quenching thirst. It can significantly improve the yin deficiency constitution of middle-aged and elderly people, and has a very broad market prospect. Some scientific research institutions and business units in my country have continuously explored and tested the tissue culture and artificial cultivation techniques of the orchid plant Dendrobium, and have achieved certain results. However, due to serious pests and di...
