Insect pest control method for medicinal plant cultivation base

Abstract

The invention discloses an insect pest control method for a medicinal plant cultivation base. The method comprises following steps: (1) performing high-temperature steam sterilization for crushed and mixed soil matrixes so as to reduce eggs in the soil; (2) for platform beds and ground beds of greenhouses, employing lack light lamps to trap and kill insect pests; (3) for field ridges and seedbeds attacked by the insect pests, mixing a chlorpyrifos solution which is diluted by 2000 times with cabbage leaves, and placing the mixture near the field ridges and seedbeds; and (4) for field ridges and seedbeds attacked by fungus gnats, employing yellow boards and blue boards to trap and kill fungus gnat adults. Through the combination of physical control and chemical control, insect pests, such as cutworms, scarabs, sciarid flies and soil root-knot nematodes, which severely do harm to seeds, seedlings and adults of pairs polyphylla and panax japonicas majoris can be targetly and comprehensively controlled, the method is low is cost and is easy to perform, and the method can be used for bases and farmer households on a large scale.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a method for preventing and controlling pests in medicinal plant cultivation bases. Background technique [0002] Dianzhonglou and Pearl Ginseng are both listed in the "Chinese Pharmacopoeia" and "Drug Standards of Yunnan Province". They are mainly produced in Yunnan and are relatively expensive traditional Chinese medicines. As an important medicinal plant resource, some medicinal plant cultivation bases have carried out large-scale introduction, planting and breeding. Due to the lack of natural enemies and changes in the growth environment, the introduced and cultivated Prunus dianthus and Ginseng are faced with the threat of insect pests that do not exist in the wild environment, mainly including cutworms (larval damage), scarabs (larvae and adult damage), and fungi mosquitoes ( Larva damage), soil nematodes, etc., have a great degree of harm to the introduced and cultivated plan...

AI Technical Summary

Problems solved by technology

Due to the lack of natural enemies and changes in the growth environment, the introduced and cultivated Prunus dianthus and Ginseng are faced with the threat of insect pests that do not exist in the wild environment, mainly including cutworms (larval damage), scarabs (larvae and adult damage), and fungi mosquitoes ( larva damage), soil nematodes, etc., have a great degree of harm to the introduced and cultivated plants, germinated seedlings, and even sowed seeds, which can lead to plant yield reduction, crop failure, and even large-scale death

Among them, cutworms are the larvae of Noctuidae insects, also known as root-cutting insects and night robbers. They mainly harm the stems and fine roots of plants. Or bitten off, will directly affect the transportation of nutrients and flowering and fruiting, which is extremely harmful, and the wound is also very easy to infect other diseases, such as stem rot. Effectively protect plants from damage; scarabs, larvae also known as grubs, larvae gnaw on plant roots underground, adults gnaw on leaves, are a very harmful common field pest, found in many medicinal material planting bases, mainly It is controlled by trapping adult lamps and larva poisonous bait; Oculomyces is a pest under the genus Oculomidae, which mostly occurs in high temperature and humid environments, and the succession speed is extremely fast. It can reproduce one generation in an average of 15 days, and many The mushroom cultivation industry has been greatly affected. Since the genus Dianchi and Ginseng are mostly propagated by seeds, the germination environment of the seeds is usually warm and humid, and they are very vulnerable to the fungus. The larvae of the mushrooms file through the file-sucking mouthparts to open the seed coat and release it. Eating endosperm and embryos can easily lead to seed mildew, deterioration and embryo necrosis, greatly reducing the germination rate of seeds, and will also eat new roots and shoots of seedlings, especially newly germinated seeds. It is a kind of medicinal plant planting base. As a newly discovered important pest, there has been no report on the impact of the fungus on the planting of P. dianthus and Ginseng. For the fungus, the physical trapping and killing of the fungus is mainly done by setting up yellow boards and blue boards, which greatly reduces the population density and reproductive efficiency, and reduces Probability of plant seedlings and seeds being eaten by fungus larvae; soil nematodes are an important soil-borne pest with strong adaptability and are easily spread with animal feces, especially in soil that has been cultivated for many years. The current price range is large Some medicinal material planting bases and farmers still retain the habit of applying farmyard manure, which greatly increases the chance of plants being infected with soil nematodes. In addition to drilling into plant tissues to lay eggs, soil nematodes can also spread root rot, root nodule, stem A series of bacterial and fungal diseases, such as rot and stem blight, cause compound infections and are extremely harmful. Sterilization of the soil matrix can effectively prevent nematodes and eggs in the soil, and reduce the chance of plant infection and disease

[0003] So far, the control methods related to scarabs, cutworms and soil nematodes in the prior art are mostly the chemical poisoning method of spraying pesticides, and the use of physical+chemical comprehensive trapping and targeted control in actual production has not been reported. The present invention It is a comprehensive control method for pests in the cultivation base of medicinal plants (Dian Chonglou, Pearl Ginseng). According to the actual pests, targeted, multi-method and phased prevention and control can avoid the impact of pesticide residues caused by blind application of pesticides. , to ensure plant reproduction, growth and health
