Abstract
The invention belongs to the environment-friendly technical field of snail-killing plant resource utilization, and particularly relates to a method of utilizing an alien invasive plant Ambrosia artemisiifolia to control a harmful mollusc golden apple snail which invades South China. The method comprises the step of adding dried powders of the alien invasive plant Ambrosia artemisiifolia to directly control the golden apple snail, and is characterized in that 1) the utilized plant is Ambrosia artemisiifolia (asteraceae); and 2) the dosage of the dried powders of Ambrosia artemisiifolia is 10 g/L. The method has the advantages that the plant material which is Ambrosia artemisiifolia is a common alien invasive plant in South China, so that the plant is easily obtained, and under a certain dosage, the golden apple snail can be effectively controlled.
Description
Technical field
The invention belongs to the environmentally friendly technical field of killing spiral shell plant resources utilization, be specifically related to the method for Alien Invasive Plants artemisiifolia in the application killed in Pomacea canaliculata and this application.
Background technology
Pomacea canaliculata is that the danger received much attention in the world is in recent years harmful to biological invasion, and its strong stress resistance, feeding habits are assorted, heavy, the growth rate having surprising fertility He be exceedingly fast, and endangers serious to south China eating rice production and rice field bio-diversity.At present, the medicament that China's control Pomacea canaliculata uses is chemical agent substantially, except easy contaminated environment, also there is the problem that price is high, large to nontarget organism toxicity.The development and utilization of killing spiral shell plant resources is one of biology important channel of killing spiral shell.Utilize botanical pesticide to prevent and treat Pomacea canaliculata and there is the features such as easy to use, with low cost, environmental pollution effect is relatively little.Up to now, nearly 1500 Plants are used to ovicidal trait test, but this is numerous floristic sub-fraction on the earth.Artemisiifolia
ambrosia artemisiifoliabe the malignant weed of invading South China of China in recent years, have and breed rate of propagation faster, cause serious economic loss with having given invasion, also threatened the bio-diversity of South China simultaneously.Therefore, utilize this pernicious instruction plant of artemisiifolia to kill Pomacea canaliculata, not only effectively can prevent and treat Pomacea canaliculata, spreading of instruction plant can also be controlled to a certain extent, and then play effect of " double gain ", " combatting poison with poison ", " turning harm into good ".
Summary of the invention
A kind of Alien Invasive Plants artemisiifolia is the object of the present invention is to provide to kill the application in Pomacea canaliculata, and utilize this Alien Invasive Plants artemisiifolia to kill the method for rice field Pomacea canaliculata application, suppress the diffusion of instruction plant to spread to a certain extent, i.e. " double gain " simultaneously.The method, by adding the dried powder of instruction plant artemisiifolia in paddyfield water, directly kills Pomacea canaliculata.
In order to reach above object, the present invention by the following technical solutions:
Alien Invasive Plants artemisiifolia is killing the application in Pomacea canaliculata, it is characterized in that killing Pomacea canaliculata with artemisiifolia.
The present invention provides a kind of described artemisiifolia killing the method applied in Pomacea canaliculata in addition, it is characterized in that directly adding in the water body containing Pomacea canaliculata by disposable for artemisiifolia powder day or night, wherein artemisiifolia powder is being 2 ~ 20g/L containing the consumption in the water body of Pomacea canaliculata, and the distribution density being applicable to Pomacea canaliculata is no more than 80/m
2the rice field of left and right.The lower limit that the experiment proved that this consumption is 2g/L, if consumption is too small, then and only can partial injury Pomacea canaliculata.After adding, a powder part floats on the water surface, and a part of sedimentation is water-bed, all can play toxic action to Pomacea canaliculata.
The consumption of described artemisiifolia powder is 2-20g/L
The consumption of described artemisiifolia powder is preferably 5-15g/L.
The consumption of described artemisiifolia powder is more preferably 10g/L
The preparation method of described artemisiifolia powder is: by air-dry for artemisiifolia plant, shred post-drying, pulverizing, cross 40 ~ 60 mesh sieves (particle diameter 0.425mm ~ 0.250mm).
The preparation method of described artemisiifolia powder, after being preferably the oven dry of artemisiifolia plant, pulverizing, crosses 40 mesh sieves.
The preparation method of described artemisiifolia powder, is preferably the whole plant of artemisiifolia.Such artemisiifolia powder that can make comprises composition as much as possible, ensures killing effect.
The present invention has following beneficial effect:
(1) vegetable material artemisiifolia is the common instruction plant of South China, obtains easily;
(2) processing method is easy and simple to handle, without the need to the program of complexity, is convenient to peasant and operates in field, cost-saving, reduces and pollutes;
(3) be conducive to carrying out Ecological Control to invasion animal Pomacea canaliculata, and be that the recycling being harmful to instruction plant opens new approach, research that is ecological for invasion and biotic intrusion control technology has great reference value.
Accompanying drawing explanation
The relation of Fig. 1 artemisiifolia dosage and adult Pomacea canaliculata lethality
Embodiment
Embodiment 1
This research and utilization instruction plant artemisiifolia kills rice field Pomacea canaliculata, and concrete steps comprise:
1. gather instruction plant artemisiifolia, by vegetable material wash clean, dry in the shade in ventilation;
2. the vegetable material after shredding dries 24 h in the constant temperature blast drying oven of 60 DEG C, is pulverized by vegetative sample cracker, crosses 40 mesh sieves, is loaded in plastic sack by dry powder sample and seals, be placed in drier and save backup.
3., when using, artemisiifolia dry powder 10 g/L is added in water body the Pomacea canaliculata killing 95% after 3 days.
Method provided by the present invention effectively can kill Pomacea canaliculata, and the artemisiifolia through different dosage is verified Pomacea canaliculata toxicity test, and experiment contrast does not add artemisiifolia.Pomacea canaliculata is put into, clear water 1.0 L(water temperature 25 ~ 30 DEG C in plastic basin), after adding artemisiifolia dry powder 5 g, 10 g, after 5 days, Pomacea canaliculata lethality reaches 41% and 98% respectively, low concentration adds artemisiifolia dry powder 2g, and also cause the Pomacea canaliculata of 25% dead after 5 days, its lethality is as shown in table 1.
The artemisiifolia powder of the different addition of table 1 is to the killing effect of Pomacea canaliculata
Embodiment 2
Collect artemisiifolia, by artemisiifolia wash clean, dry in the shade in ventilation, shred;
Artemisiifolia after shredding dries 24 h in the constant temperature blast drying oven of 60 DEG C, is pulverized by vegetative sample cracker, crosses 40 mesh sieves, is loaded in plastic sack by gained artemisiifolia dry powder and seals, be placed in drier and save backup.
Pomacea canaliculata of growing up is large to paddy rice food ingestion, and harmfulness is the most serious, and Ontogenetic pattern is strong, therefore tests described artemisiifolia dry powder in this example to the toxicity of adult Pomacea canaliculata.80/m is put in basin
2adult Pomacea canaliculata (spiral shell weighs more than 6.5 grams /), clear water 1 L(water temperature 25 ~ 30 DEG C), process dosage is respectively 2 g, 5g, 10g, 15g, 20g.Observe at different time and find, add artemisiifolia dry powder 10 g/L, Pomacea canaliculata lethality of growing up afterwards for 3 days reaches 83%, and the lethality of Pomacea canaliculata of growing up afterwards for 4 days reaches 90%.Meanwhile, when adding after artemisiifolia powder the 5th day, the lethality of Pomacea canaliculata of growing up raises (Fig. 1) gradually along with the increase of different artemisiifolia powder dosage, and therefore artemisiifolia has good killing effect to adult Pomacea canaliculata.
