Plant fermentation extract for preventing and treating Chinese chive maggots and preparation method thereof

Abstract

The invention relates to the technical field of vegetable pest control, and particularly discloses a plant fermentation extract for controlling Chinese chive maggots and a preparation method thereof.The plant fermentation extract for preventing and treating Chinese chive maggots is characterized by comprising the following steps and raw materials: fermenting, extracting and pulverizing the following raw materials in parts by weight: 20 to 25 parts of radix sophorae flavescentis, 3 to 5 parts of pericarpium citri reticulatae, 20 to 25 parts of cyrtomium fortunei, 5 to 10 parts of akebiaquinata, 0.2 to 0.3 part of pollen, 15 to 20 parts of radix bupleuri, 0.01 to 0.02 part of cordyceps sinensis, 10 to 15 parts of pinellia ternate, 0.5 to 1 part of red ginseng, 0.02 to 0.03 part of iron-enriched yeast, 5 to 10 parts of liquorice and 0.01 to 0.02 part of selenium yeast. The product is non-toxic, pollution-free, green, environment-friendly, free of chemical pesticide components, capable oferadicating generation of chemical pesticide residues from the source, good in insecticidal effect, capable of effectively improving the soil structure and increasing the number and activity of microorganisms in soil, beneficial to vegetable growth and capable of increasing the yield and quality.

Description

[0001] (1) Technical field [0002] The invention relates to the technical field of vegetable diseases and insect pests prevention and control, in particular to a plant fermentation extract for preventing and treating leek maggots and a preparation method thereof. [0003] (2) Background technology [0004] Leek, a perennial perennial root vegetable of the Liliaceae family, is rich in nutritional value, rich in protein, calcium, iron, vitamin C, etc. At the same time, leeks contain special ingredients such as volatile essential oils and sulfides, which can help regulate liver qi, increase appetite, and enhance digestion. Wait, Li Shizhen praised leeks as "the most beneficial person in the dish." Leek has always been loved and welcomed by people, but as a persistent underground pest, leek maggots restrict the development of leek cultivation. [0005] Leek maggots are the larvae of the larvae of chives and onion flies. The larvae and onion flies suck juice when the leek is harvested, so...

Problems solved by technology

[0007] In the prior art, there have been reports on the prevention and treatment of chive maggots by botanical pesticides. For example, Chinese patent CN104086325A discloses a method for biological control of chive maggots. , although it is environmentally friendly and pollution-free, but due to the large number of bacteria in the biogas slurry, it will affect the normal growth of leeks, and the control effect is not ideal

Chinese patent CN105961460B discloses a plant-derived medicament for the prevention and treatment of chive maggots, which uses extracts of Pulsatilla inflorescences, Pulsatilla pulsatillae powder, Agarica powder, tea dregs, garlic powder, citrus peel extracts, scallion extracts, tobacco liquid, Castor leaf powder, matrine and water are mixed, which is also environmentally friendly and pollution-free, but the cost of raw materials is high, the preparation and synthesis are complicated, and the amount per unit area is large, which does not meet the actual production needs
