Kill the dish worm after washing the hydroenergy of fish's viscera The expert claims to be effective but the reason is not clear
A citizen recommends the insecticidal new method to this newspaper, expert's test has slight results, but does not still know the reason. Recently, one come from the intersection of Jiangsu and Xinyi call, eat, print reader of younger brother claim, say he finds a kind of biological method can drive away the common insect pests such as blue and green worm, aphid on the vegetable plot - -Water that will wash fish's viscera is sprayed in the vegetable plot. Mulberry leaf affix wash fish and water, feed, die silkworm " I oneself make numerous experiments at home, water using washing the fish, especially has washed water of the viscera is put into the beverage bottled, spray it to the infested dish on the ground, the insect will roll up for a moment, will die in the near future, within some time, the regenerated worm of vegetable plot, I think if this kind of method can be popularized out, the vegetable grower can no longer use chemical pesticide, ordinary people can eat the vegetables of high quality. " Eat the old gentleman for 67 years old this year, work in the Xuzhou machine factory before retiring, retire, make earnest efforts to study various practical methods. He holds a pile of handwritten paper to represent to a reporter, record the concrete working technique above. The old gentleman claimed to have a piece of ground to plant vegetables at the gate of home oneself, once drove worms by this kind of method many times, tell to the neighbours of some relatives, has practised too. "Fresh-water fishes and ocean fishes are all all right, should wash fish's viscera, the rainwater is better, the running water is possible. " Eat the principle that the gentleman claims this kind of method drives the worm to lie in the viscera of the fish can be melted in water, produce the mould, eating the grass insect will die after eating this kind of mould, but curiously, after beneficial insect such as the mantis, ladybug, dragonfly have eaten the insect after poisoning, but will not die. Eat and print the younger brother and introduce, the reason why will find this kind drives worm way, it is the experience that the mulberry of complexion of once while stemming from youngly is fed to the silkworm. "Once I picked the mulberry leaf after killing the fish, the silkworm had died manily after eating the mulberry leaf finally, I suspected whether to relate to my adhesive thing on the hand at that time. " Can test really the part and drive worms and wash fish and water and drive worms briefly? Is there a result on earth? The reporter finds limited company of biological development in science and technology of nine health that specially produces biological pesticide of Nanjing for this, invite laboratory technician Xu ZhiHui of the research and development department of this company to carry on a simple test. "I have been selected a carp, use killing a basin of water of the fish for the experiment. Divide three steps altogether. Put aphid and little blue and green worm used for experiment on a basin of green plants first, will wash fish and water to put into the bottle, the first step is to spray water, several minutes later, the insect is still here. The second step, I splash on the plant with water of the handle, we can see, there are insects that have fallen down, but the result is not obvious. The third step, in I soak the insect to and wash fish and water, will find in the near future, the insect will really die. " "This is only the simplest test, a test has contingency too, should prove that can drive worms while washing fish and water, far from enough, need very complicated test and long-time observation research. " Xu ZhiHui introduces to the reporter, through this test, can learn tentatively, washing fish and water may have some driving worm's function slightly, cause death eating the what is called Mr. on earth of the worm " The mould " Can't draw a conclusion. Reason need further proving, in above-mentioned test, washing why on earth causing death the insect finally fish and water also? Researcher Xu says, perhaps the multi-type that have, probably really have a certain material which kills the insect in the viscera of the fish on one hand, on the other hand, get rid of in the feed to feed fish, contain, can cause death things of insect in the used for studying water, that is to say " perhaps the fish are problematic, perhaps water is problematic too. " "Another one have to be considered, after driving worms like this, it is hard to tell too whether the vegetables are polluted at the same time, need detailed test and draw the conclusion. " Researcher Xu tells reporters. Chain: Surround plant biological pesticide further, protect, " heard that uses tobacco water, water displaced worm of soap, but not still really heard that used washing fish and water. " Jiangsu Province the intersection of Academy of Agricultural Sciences and the intersection of vegetables and the intersection of sheep and chief introduce, biological pesticide at the market basically adopts the plant thing at present, for instance China tree fruit, Radix seu Caulis Derridis Trifoliatae are precise,etc., utilize the material extracted and drawn from it, make into the plant anthelmintic, has already been proved to be pollution-free, without residue, nonpoisonous and harmless to people and animals. Reporter know compared with chemical pesticide, biological pesticide adoption rate high in our country's agricultural production at present, the result is not so with instant effect as chemical pesticide on one hand, on the other hand the cost is higher. But from the angles of the environmental protection and security, biological pesticide is really even better. (reporter Liu Yang)
