[0006] CN104429548B) discloses a method for controlling exotic weeds Solidago canadensis, by planting kidney bean and calabash seedling plants to produce allelopathic effect, utilizing biological crusts etc. to have adsorption, absorbing allelochemical substances to weaken the allelopathic effect of Solidago canadensis Inhibition, at the same time, using the entwining characteristics of vines to achieve the purpose of shading to inhibit the growth of solidago canadensis, which mainly inhibits the growth of solidago canadensis through the symbiotic allelopathic effect of different species, which makes it in the process of use more limited
At present, there is no specific report stating which plants are extracted from which extracts and allelopathic effects are used to prepare biological agents for inhibiting the invasive plant Solidago canadensis

Embodiment 1

[0046] The area where the exotic species Solidago canadensis grows is selected to be irrigated with the aqueous solution of the biological agent containing the water extract of Setaria, specifically by watering from the roots, and the water extract of Setaria used here is the whole plant of Setaria. The concentration of the aqueous solution containing the foxtail water extract can be prepared according to actual needs, and the watering cycle can be watered once every 2 weeks after the first watering, and the growth plant height of the cycle can be analyzed in the actual process. The specific analysis results are as Figure 1-5 shown.

[0047] In order to better illustrate the ratio of experimental data, Figure 1-5 The biological preparations used in the experimental group are the aqueous solution of the foxtail water extract at a concentration of 0.1g / mL. from above Figure 1-5 The analysis results show that the biological agent adopted can effectively realize the growth o...

Embodiment 2

[0049] Select the area where the exotic species Solidago canadensis and the symbiotic plant Achyranthes bidentata are used for watering with an aqueous solution containing the water extract of Setaria, specifically by watering from the root, and the water extract of Setaria used here is the whole Setaria plant. The concentration of the aqueous solution that contains the foxtail water extract can be formulated according to actual needs, and the watering cycle can be watered once after the first watering every 2 weeks, wherein, the inhibitory effect on Solidago canadensis can reach the same level as in Example 1 The corresponding inhibitory effects are basically the same; at the same time, in order to better explain the proportion of experimental data, Figure 6-9 The biological preparations used in the study were all aqueous solutions of the aqueous extract of Setaria chinensis at a concentration of 0.1 g / mL. Then by analyzing the growth plant height of Achyranthes bidentata in...

Embodiment 3

[0052] The area where the exotic species Solidago canadensis and the symbiotic plant Polygonum cuspidatum is selected to be irrigated with an aqueous solution containing the water extract of Setaria, specifically by watering from the roots, and the water extract of Setaria used here is the whole plant of Setaria. The concentration of the aqueous solution containing the foxtail water extract can be formulated according to actual needs, and the watering cycle can be watered once after the first watering every 2 weeks; wherein, the inhibitory effect on Solidago canadensis can reach the same level as that of the embodiment 1 The corresponding inhibitory effects are basically the same; at the same time, in order to better explain the proportion of experimental data, Figure 10-13 The biological preparations used in the study were all aqueous solutions of the aqueous extract of Setaria chinensis at a concentration of 0.1 g / mL. Then by analyzing the growth and plant height of Polygon...

Abstract

The invention relates to a biological preparation and method for inhibiting growth of foreign species of solidago canadensis L., and belongs to the technical field of ecological prevention and controland biological agents for weed control. The invention provides the biological preparation and method for inhibiting growth of foreign species of solidago canadensis L. to avoid the harm and limitation of an existing inhibitor. The biological preparation contains an aqueous extract of green bristlegrass, and green bristlegrass adopted for the aqueous extract of green bristlegrass is the herbs of green bristlegrass. The method comprises the step of adopting the biological preparation containing the aqueous extract of green bristlegrass for watering an area in which solidago canadensis L. is grown, wherein green bristlegrass adopted for the aqueous extract of green bristlegrass is the herbs of green bristlegrass. The preparation is capable of inhibiting the absorption of nutrients by solidago canadensis L. and damaging a photosynthesis system of solidago canadensis L., so that the plant height and total biomass of solidago canadensis L. are inhibited, and the effect of effectively inhibiting the growth is achieved.

Description

technical field [0001] The invention relates to a biological agent and method for inhibiting the growth of foreign species Solidago canadensis, belonging to the technical field of ecological control and weed control biological agents. Background technique [0002] Solidago canadensis, also known as golden stick grass, yellow warbler, goldenrod, belongs to the genus Solidago genus in the family Asteraceae, and is a perennial herb. Solidago canadensis was introduced from abroad as an ornamental plant, and it became wild after the 1980s. It is an invasive alien weed and has been included in the list of important alien harmful plants in my country. [0003] Solidago canadensis competes with other symbiotic species for nutrients, water and space during the growth process, resulting in the death of the symbiotic local species, and also invades crop fields such as cotton, corn and soybean, affecting the yield and quality of these crops, causing direct And indirect economic losses,...
