浙江省嘉兴市清河中学生物兴趣小组在沈莹老师指导下,于1996年4月至8月进行了微波辐射对菜豆生长发育影响的实验。 他们将280颗粒大饱满的菜豆种子平均分为两组,实验组的140颗种子用家用微波炉(150W)照射30秒;另一组的140颗未经处理,作为对照组。在1996年4月24日,选择本市嘉北乡百花村4组一块座北朝南,长9.5米、宽3.2米的壤土地播种。将280颗种子分播4畦,每畦有两纵行,每行35穴,行距40厘米,穴距25厘米,靠西侧的两畦(4行)为实验组,靠东侧的两畦(4行)为对照组,分别插入木牌标
Under the guidance of Professor Shen Ying, a group of interest in Qinghe Middle School, Jiaxing City, Zhejiang Province conducted an experiment on the effects of microwave radiation on the growth and development of kidney beans from April to August 1996. They average 280 seeds of full bean seeds into two groups, 140 seeds of the experimental group were irradiated with household microwave oven (150W) for 30 seconds; the other 140 were untreated as a control group. On April 24, 1996, 4 groups of Baihua Village, Jiabei Township, Jiaocheng City of this Municipality were selected to sow a piece of soil spreading southward, 9.5 meters long and 3.2 meters wide. 280 seeds were distributed 4 每, each 畦 has two vertical lines, each 35 lines, spacing 40 cm, hole distance of 25 cm, by the west of two 畦 (4 lines) as the experimental group, by the eastern two 畦(4 lines) as the control group, respectively, insert the wooden sign
