The shaping craft of the termite bait was studied by orthogonal method.The results of the experiment showed that the best shaping craft of the termite bait of the cane powder was:the thin cane powder,10% adhesive, 5 s of crush time and 200% water;while the best shaping craft of the termite bait of the pine fritter was:the thin pine fritter,10% adhesive,5 s of crush time and 100% water.展开更多
