[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 is grown is selected to be irrigated with an aqueous solution containing a biological preparation of foxtail grass water extract, specifically by watering from the roots, where the foxtail grass water extract used here is the whole plant of foxtail grass. The concentration of the aqueous solution containing foxtail water extract can be prepared according to actual needs. The specific analysis results are as Figure 1-5 shown.

[0047] In order to better explain the proportion of experimental data, Figure 1-5 The biological preparations used in the experimental group were all aqueous solutions of foxtail water extracts at a concentration of 0.1 g / mL. from the above Figure 1-5 The analysis results show that the biological preparations used can effectively achieve a good inhibitory effect on the plant height, total biomass and root, stem and leaf biomass growth of Solidago canadensis, indicating that the used foxta...

Embodiment 2

[0049] The area where the exotic species Solidago canadensis and the symbiotic plant Achyranthes are grown is selected to be irrigated with an aqueous solution containing a foxtail water extract, specifically by watering from the roots, where the foxtail foxtail water extract used here is the whole plant of foxtail. 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 again after 2 weeks after the first watering. 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 this study were all aqueous solutions of foxtail foxtail water extracts at a concentration of 0.1 g / mL. Then, through the analysis of the growth plant height of Achyranthes in the process, the specific analysis results are as follows: Figure 6-9 shown.

Embodiment 3

[0052] The area where the exotic species Solidago canadensis and the symbiotic plant Polygonum cuspidatum are grown is selected to be irrigated with an aqueous solution containing a foxtail water extract, specifically by watering from the roots, where the foxtail foxtail water extract used here is the whole plant of foxtail. 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 again after 2 weeks after the first watering; wherein, the inhibitory effect on Solidago canadensis can reach the same level as the example in the 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 10-13 The biological preparations used in this study were all aqueous solutions of foxtail water extracts at a concentration of 0.1 g / mL. Then, through the analysis of the growth and plant height...

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 preparation and a method for inhibiting the growth of foreign species Solidago canadensis, belonging to the technical field of ecological prevention and control and weeding biological agents. Background technique [0002] Solidago canadensis, also known as goldenrod, yellow warbler, and unicorn grass, belongs to the genus of goldenrod, and is a perennial herb. Solidago canadensis was introduced from abroad as an ornamental plant, and 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 symbiotic native species, and also invades cotton, corn and soybean fields, affecting the yield and quality of these crops, causing direct damage. And indirect economic losses, coupled with the envi...
