Description
Technical Field
The invention belongs to the technical field of biological invasive malignant weed control, and particularly relates to a method for preventing and controlling invasive weed Solidago canadensis by using a Chinese jiajiao locust.
Background
Solidago canadensis (Solidago canadensis L.) is a malignant invasive weed and poses serious threats and hazards to the ecological environment, agricultural production and human health of China. In 1935, the extract is introduced into the Shanghai of China as an ornamental plant, and due to the lack of natural enemies and strong propagation and diffusion capacity, the extract is rapidly diffused to eastern coastal areas such as Jiangsu, Zhejiang and Shandong, and is continuously diffused to inland and is difficult to inhibit, the distribution range of the extract is accumulated to be more than 20 ten thousand mu, and researches show that the root-shaped sense extract of solidago canadensis can inhibit the germination rate of wheat by more than 50%; in view of the characteristics of severe harm, fast diffusion, strong adaptability and the like of solidago canadensis, the ecological environment department lists main foreign invaded species in China.
The malignant weeds are mainly controlled by physical, chemical, biological and other methods, wherein the physical method usually needs a large amount of manpower, material resources and economic investment, but usually can only take effect in a short term, cannot solve the problem in a long term, and can not treat the symptoms and the root causes; chemical methods are often accompanied by contamination and secondary hazards; therefore, biological control becomes a key field of current research, and the biological control of weeds is realized by using methods such as phytophagous animals, alternative plants, pathogenic microorganisms and the like. However, due to the extremely strong propagation and diffusion capacity of solidago canadensis, a biological method capable of effectively treating solidago canadensis is not found at present.
At present, the method for treating solidago canadensis in China mainly adopts glyphosate herbicide, manual cutting, extensive removal and the like, but the effect is not obvious, and the main reason is that natural enemy clonine for inhibiting the wild growth of the solidago canadensis is lacked, such as herbivorous animals including white tailed deer, phytophagous sphingomydia, beetles and the like in the original production place, and writers find that the solidago canadensis leaves are planted and eaten and part of seedlings even only remain main stems during the experiment in 2021 year 4-11, and after careful investigation and subsequent attention verification, the acridid chinese jiana has good prevention and control effects on solidago canadensis, and the distribution ranges of the acridida sinensis and the solidago canadensis are overlapped. Similar findings are not found at present in China, and a complete prevention and control ecological chain is not formed by specific collection, release and control.
Disclosure of Invention
Aiming at the problems in the prior art, the invention provides a method for preventing and controlling invasive weed Solidago canadensis by using a Chinese jiajiao locust, and particularly relates to a method for preventing, controlling and treating the Solidago canadensis by using the Chinese jiajiao locust under the supplement of a physical light source, so as to solve the problem that the Solidago canadensis quickly spreads and is difficult to control.
A method for preventing and controlling invasive weed Solidago canadensis by using a Chinesia ensisii, comprises the following steps:
(1) collecting the locusta zhonghuajiangjiao for later use;
(2) placing a solar LED lamp in a plant cluster of Solidago canadensis;
(3) putting the locusta chinensis collected in the step (1) in a seedling stage of solidago canadensis;
(4) and (3) putting the locusta chinensis collected in the step (1) again in the long-term solidago canadensis.
In the step (1), the collection method of the acridia sinensis comprises artificial culture or natural collection, wherein the artificial culture method comprises the steps of artificially capturing adults for indoor culture, pairing males and females to lay eggs, and hatching out larvae; the natural collection method is to artificially catch small adults with the length of about 1-3cm in an aeration wide-mouth bottle in a vegetable shed, a grass cluster and a weed community.
In the step (2), when the solar LED lamps are arranged in the Solidago canadensis distribution cluster, the irradiation area is selected<2m2The solar LED lamps are arranged according to the characteristic point sources of the clusters at intervals of more than 3m, and are beneficial to the accumulation of insects for feeding.
The solar LED lamps are placed on the ground mainly in the seedling stage and can effectively move horizontally along with the breeding state; in the growing period, new top leaves need to be supplemented with light along with the change of the plant height, and the lamp is moved vertically and horizontally to attract insects to breed and feed the top leaves.
In the step (3), when the Solidago canadensis is put in the seedling stage, 4-6 locusts are put in per meter2The population density of the insect is released. The seedling stage of the solidago canadensis is generally 3-4 months, and the leaves in the seedling stage are tender and have weak self-compensation capacity.
In the step (4), when the Solidago canadensis is put in the locusta chinensis for a long period (6-7 months) in the step (4), 10-12 heads/m are put in2The population density of the insects is released; the compensation capacity is strong in the growing period, but the formation of a large number of inflorescences can be prevented by putting a proper amount of larvae.
The method for feeding the locusta zhonghuajiangjiao comprises the following steps: slightly clamping the captured small adults onto Canadian Solidago canadensis leaves by using tweezers, wherein the whole area is uniform and is randomly released at multiple points; the pest control agent can be thrown for multiple times at different time, the interval period of the throwing time is 7 days, and the survival rate of target species is prevented from being reduced or the target species is prevented from rapidly moving across regions due to weather and natural enemy catching and killing because the small adults like dry heat, so that the biological control efficiency and effect are influenced.
The acridia sinensis is a parasitic insect, but the acridia sinensis has a short migration distance and phototaxis, so that the acridia sinensis is an ecological risk and small biological method for attracting the acridia sinensis by physical supplementary lighting in a densely distributed region of solidago canadensis. The even number pairs are mainly put into the acremophilus canadensis, so that the acremophilus canadensis after being grown is facilitated to be mated and propagated, and the control efficiency of solidago canadensis is improved.
The control of the Chinese acridid locust is that in the later stage of the prevention and control of the solidago canadensis, some animals with higher food chains such as beneficial birds and the like can be introduced into the feeding area of the Chinese acridid locust to cooperatively prevent the flood and disaster formation of the Chinese acridid locust; the phototaxis of the acridida sinensis can be utilized, and a light source is utilized to attract, gather and trap the acridida sinensis at night; especially, the locusta zhonghuajiangjiao has short life (2-3 months) and can die naturally, so the harm is extremely small.
The method for preventing and controlling the Solidago canadensis by using the locusta chinensiss has the overall implementation process of placing a solar light supplement lamp, throwing insects at a seedling stage, adjusting light supplement at a growth stage, and throwing the insects at the growth stage again.
Compared with the prior art methods such as chemical prevention and removal, artificial mowing and the like, the method has the advantages that:
1) the survival state of the solidago canadensis without natural enemies in China is thoroughly changed;
2) the acquisition method is simple, strong in operability, wide in application range, small in ecological interference to the region and free of risks;
3) the adult Chinese glaucous xyphocarpus has strong reproductive capacity, and can thoroughly destroy the growth diffusion situation of solidago canadensis in a large area for a long time;
4) makes full use of the biological characteristics of the locusta chinensises, not only can effectively control the diffusion and the propagation of the solidago canadensis, but also can avoid the flood and the disaster of the released locusta chinensises,
5) in the long-term of Canada solidago, the light source is used for attracting insects to the top leaves for planting, so that the flower species are further limited, and the purpose of delaying invasion and diffusion is achieved.
