临安县上甘公社农科站、供销社和樟村大队科研小组一起,在区、社领导的支持下,在科教电影《青蛙》的启发下,在1973年早稻生产中开展养蛙治虫试验,获得了可喜的成果。他们在总结两次失败的教训的基础上,在一丘1.40亩田里用竹帘子拦出0.18亩田,放养了一水桶蝌蚪,与不放养的1.22亩田进行对比。但由于竹帘间隔太大,小蝌蚪慢慢地钻到外面去了。于是他们活捉了100只会跳的大小青蛙放入试验区,叫一只青蛙管50丛稻。于7月2日检查
Lin’an County Shanggong Commune Agricultural Station, supply and marketing cooperatives and Zhangcun brigade research team, with the support of district and community leaders, science and education film “Frog” inspired by the early rice production in 1973 to carry out frog pest control experiment, Get gratifying results. On the basis of summing up the lessons of the two failures, they stopped the 0.18-mu farmland with bamboo curtains on a 1.40-acre plot of a hill, stocked a bucket of tadpoles, and compared them to 1.22-mu of untreated land. However, due to bamboo curtain interval is too large, small tadpoles slowly went outside to go. So they captured 100 will jump the size of the frog into the test area, called a frog tube 50 rice.
