In 1981, I stood in the field of seeds under different conditions weeding herbicidal effect comparison test. Community trial area of 0.0765 acres, choose a more uniform soil fertility of yellow soil for seedbed. Base fertilizer: 400 barrels of mud, superphosphate 150 pounds / mu. Nutritional Bowl film cover nursery, a total of three sheds, each shed 10 meters long, 1.7 meters wide, an area of 0.0255 acres.
