Embodiment 1

[0044] Example 1 Invading Weeds' Competitive Effect and Screening of Its Alternative Species

[0045] Test Materials: Materials in Mikania Micrantha H.B.Key from the Town of Dehong Prefecture Mangshi. The local plant species is based on the occurrence of Tropical Fruit (Orange, Lemon, Litchi, Litchi, Litchi, and Passion Fruits, etc.), and select 4 categories of 16 plants to Weakani competition through investigations, collection, expansion and pre-experiment. Trait system research, including:

[0046] Class A is a one-year single leaf plant A1 rice, A2 ducks (ARTHRAXON HISPIDUS) and A4 Dog Tail (Setaria Viridis).

[0047] Class B is a year of bonchiya B1 sweet potato (Ipomoea Batatas), B2 Pursum (ACALYPHA Australis) and B4 Dragonfumes (Solanum Nigrum).

[0048] Class C is a perennial leaf plant C1 wrinkled dog tail straw (Setari APLICATA), C2 蔗 蔗) (Triarrhena Sacchariflora) and C4 荻 (Triarrhena Sacchariflora).

[0049] Class D is a born twin plant D1 Piglore (Crotaacummongolicum), ...

Embodiment 2

[0070] Example 2 Invader of Weedushai and Cave on Alternative Species Difference

[0071] 2.1 Test Materials: According to Example 1, the results of the rated competitiveness of the martyrid were measured, evaluated, and alternative species screening results by local plants. Taking miogan as a chemical donor plant, rice, purslane, and wrinkled dog tail straw, etc., as well as internationally recognized chemical model receptor plant lettuce, a chemical surveillance plant (chemostat receptor plant See Table 2 to implement the series 2-1 to 2-14). Testing 4-story orchard soil with the difference of Wikaniosis (see Sample Logging A, B, C and D), respectively

[0072] 2.2 Test method:

[0073] 2.2.1 Vulough invasive soil sample selection, selecting ecological geography, soil types, and the same citrus garden as the texture. Specifically, it is Fengping Town, Mangshi City, Dehong, Yunnan Province (Northern 98.45499, north latitude 24.364604, 857.5m altitude); the soil type is red soil (...

Embodiment 3

[0097] Example 3 Alternative Control combined with agricultural prevention measures to the prevention and treatment of miracoo

[0098] Test materials: rice grass, grass, fruquetted dog tail grass, maplemao, sweet potato, purslane, odor Dan and Dandelion 8 local plants as an alternative to control the trick test.

[0099] Test method: Based on the sample B (Wikihidi cover 0.8), the sample C (Wikhani cover 30 ~ 60%, the chemical effect of lettuce Comprehensive index RIS is 0.5 ~ 0.8) and sample D (Wikanji cover> 60%, the average macaromile average density of all-year marticity RIS 2 4-6 strains / m 2 And 9 / strain M 2 The above, 8 local plants (see Example 3 Test Material) were screened, and alternative species were taken in conjunction with the basic seedlings of each alternative species and the basic seedlings of the alternative species in Example 1: the density ratio of miogans 1: 1, alternative species: mild density ratio 3 to 1: 1, alternative species: the density ratio of t...

Abstract

The invention discloses an orchard ecological control and restoration construction method based on allelopathy of invasive weed mikania micrantha. According to the method, on the basis of allelopathy and selectivity of the mikania micrantha on alternative species, the alternative species with high tolerance and competitiveness are reasonably planted, and agricultural control, physical control or chemical control is combined. For plots with the allelopathy comprehensive index RIS ecologically determined to be greater than 0.8 according to an allelopathy mode receptor plant lettuce, bengonium bracteatum, hispid arthraxon, sweet potato or purslane are interplantedafter deep and shallow rotation tillage; for plots with RIS equal to 0.5-0.8, a sweet potatoes, purslane, laggera pterodonta or dandelion is interplanted after deep ploughing; and for plots with RIS smaller than 0.2, after shallow ploughing or no-ploughing, setaria viridis, daphne odora, benthraxon or hispid arthraxon are planted in a mixed mode, and 83.0-123.0 g(ai) / hm<2> of selective herbicide clopyralid is applied. The control effect of the method on the mikania micrantha reaches 90.0% or above, and the plant diversity is remarkably improved by 15.0% or above.

Description

Technical field [0001] The invention belongs to the prevention and control of invasive weeds in the field of plant protection technology. Based on the allelopathic effect and selectivity of the alien species Mikania micrantha on plants in invasive habitats, alternative species with strong tolerance and competitiveness and their planting patterns are reasonably selected, and Combining agricultural control, chemical control and physical control measures respectively, an orchard ecological control and restoration method with alternative control as the core is constructed. It is a technical solution with good economic value and ecological value, and can achieve a control effect of more than 90.0% on Mikania micrantha. , a substantial technical effect that significantly restores the diversity of other plants. Background technique [0002] Mikania micrantha H.B.K, a major invasive species under key control in my country, is a perennial vine of the genus Asteraceae in the Asteracea...
