The artemisia annua tobacco vinegar liquid with the weight of 25 times to 100 times has the inhibition rate of the fusarium oxysporum of 79.17-100 percent. The soil with root knot nematode disease all the year round is irrigated, and the inhibition rate of the root knot nematode reaches 90-100%.
Description
Technical Field
The present invention belongs to the field of plant source material technology for preventing and controlling root-knot nematode disease and root rot of crops and Chinese herbal medicine. Relates to a vinegar liquid prepared by mixing artemisia annua straws and tobacco straws, and the vinegar liquid can inhibit root-knot nematodes and Chinese herbal medicine root rot pathogens.
Background
Artemisia annua Linn, also called Artemisia annua L, is an annual herb of Artemisia of Compositae, widely distributed in various provinces of China, is a traditional Chinese herbal medicine, and has different action mechanism of effective component artemisinin in antimalarial field from traditional quinine antimalarial drugs. However, although the artemisia annua plays an indispensable role in the medical health of human beings, because the artemisia annua grows and breeds very quickly and has strong habitat adaptability, the east and south provinces of China grow on roadside, wasteland, hillside, forest edge and the like, other provinces also grow on grassland, forest grassland, dry river valley, semi-desert, gravel slope and the like, and also grow on salinized soil, often germinate in large quantities in the late spring and early summer to develop dominant weeds, and in order to prevent and control the harm of the artemisia annua serving as weeds to farmlands, grassland or forests, research and development of other potential utilization values of the artemisia annua are also needed.
After the tobacco leaves are harvested, a large amount of tobacco plant residues such as tobacco stems, tobacco roots and the like are remained, and if the tobacco plant residues are not removed in time, the environment of a tobacco planting area is easily polluted. The lignification degree of the tobacco (Nicotiana tabacum) straw is high, the tobacco is very difficult to decay, and the resource utilization of the tobacco (Nicotiana tabacum) straw is always a difficult problem. In recent years, the tobacco main production area has serious straw burning pollution. After tobacco is harvested, in order to treat tobacco straws, the situation that dense smoke is rolled in partial areas is achieved, the treatment mode wastes precious natural resources, causes environmental pollution and multiple accidents, poses great threats to traffic safety of highways and railways, take-off and landing safety of civil aviation flights and the like, causes serious harm to human health and safety, and becomes a social problem. In order to solve the problem of relation among human resources, environment and development, the tobacco straws are efficiently and reasonably utilized, the potential utilization value of the tobacco straws is researched and developed, and the tobacco straws are also an important measure for reducing the negative influence of the tobacco straws.
The traditional Chinese medicine is a traditional Chinese medicinal material and is an important component of excellent Chinese culture. The Chinese herbal medicines belong to the most important parts of the Chinese herbal medicines, and as the economic parts and the medicinal parts of most Chinese herbal medicines are roots of the Chinese herbal medicines, with the rapid increase of the planting area of medicinal plants and the domestication of wild resources of most varieties into the large-scale planting of cultivated varieties, the rotting of the roots evolves into the most serious diseases which directly affect the yield, the quality and the commodity value of the Chinese herbal medicines, and the value of the Chinese herbal medicines is greatly affected. Moreover, the disease problem of the Chinese herbal medicine is increasingly prominent, because the microbial composition in the soil is very complex, the pathogens are various, fungi, bacteria and nematodes can cause the root rot of the Chinese herbal medicine, wherein the fungi harm is the most serious, and the root rot of various Chinese herbal medicines can be caused, for example, Fusarium oxysporum (Fusarium oxysporum) can cause the root rot of Chinese herbal medicines such as medlar, panax japonicus, polygonatum odoratum, salvia miltiorrhiza and panax notoginseng, and is one of the most harmful pathogens. The common annual incidence rate of panax notoginseng root rot is 5-20%, the serious annual incidence rate is 70%, and the incidence rate of angelica dahurica root rot is about 30%, and sometimes 80%. The overuse of chemical pesticides is increased for controlling diseases, so that the risk of qualified quality of Chinese herbal medicines and the environmental friendliness are increased, and the overuse of chemical pesticides becomes a main obstacle for the production of Chinese herbal medicines.
Root-knot nematodes (Meloidogyne spp.) are highly obligate, parasitic phytopathogenic nematodes occurring in the underground parts of plants. Root knot nematode disease is one of the main diseases in crops, economic crops and Chinese herbal medicine cultivation, and occurs to different degrees every year. As the economic parts and the medicinal parts of most Chinese herbal medicines are roots of the Chinese herbal medicines, the root-knot nematode diseases of the medicinal plants are increased along with the rapid increase of the planting area of the medicinal plants and the large-scale planting of most varieties of wild resources acclimatized into cultivated varieties. In order to control the diseases, the overuse of chemical pesticides is increased, so that the risk of qualified quality of Chinese herbal medicines and the unfriendliness to the environment are further increased, which becomes one of the main obstacles for the production of Chinese herbal medicines.
Through the literature search, the same public reports as the invention are not found.

Treatments 1, 2, 3, 4 and 5 the experimental operations were carried out as follows, except for the different vinegar solutions used as described above:
200ml of vinegar prepared by the preparation method is respectively prepared into 5000ml of solutions of 25 times, 50 times, 75 times, 100 times, 150 times and 200 times by using tap water according to the set 6 dilution gradients for later use. And (3) the prepared soil of the plot which has root knot nematode disease all year round and is uniformly developed is subpackaged in flowerpots, the israeled 208 tomatoes which are susceptible to the root knot nematode are planted, the prepared vinegar is used for irrigating (the amount of the vinegar for each irrigating treatment is equal), and the management is carried out according to a conventional planting method. After 8 weeks, the proportion of the root knots in the tomato root system in the whole root system, i.e. the percentage of the root knots, was investigated.
And (6) treatment: and (3) filling 1 part of equant soil into a flowerpot, planting the variety Israel 208 tomatoes susceptible to root-knot nematodes, and managing according to a conventional planting method. After 8 weeks, the proportion of the root knots in the tomato root system in the whole plant root system, namely the percentage of the root knots, is investigated.
And (3) test results: the vinegar solution with different dilution concentrations has an inhibition effect on the root-knot nematodes, but the inhibition effect is reduced along with the increase of the dilution times. Under the same dilution factor, the artemisia annua straws: the mass ratio of the tobacco straws is 2: the suppression effect was the best when 1 was used.
The inhibition rate of root-knot nematode is 1-root-knot percentage%.
The experimental results of example 2 are detailed in table 1.
