林木生长过程中的生物电现象,国外科学家已进行过实验研究。1984年初,国内报刊也有过特定电磁波用于治疗人、畜、禽疾病和刺激植物生长的报道。为了探明电回馈对林木生长的影响,我们于1984年7月下旬在我所四合实验站进行了电回馈对德国杂杨第一次平茬后萌生苗生长影响的试验。试验在萌生苗地块中间进行,采用田间对比试验设计,共分六组。第一组用直流+500v,第三组为直流-500v,考虑到电场对附近苗木的影响第二组为隔离组;第四、第五组采用了
Bioelectrical phenomena in the growth of trees, foreign scientists have conducted experimental studies. In early 1984, domestic newspapers and magazines also reported on the use of certain electromagnetic waves in the treatment of human, livestock and poultry diseases and stimulation of plant growth. In order to find out the effect of electric feedback on forest growth, we conducted an experiment on the effect of electric feedback on the growth of sprouted seedlings after the first stubble harvest of Populus tomentosa at our Sihe Experimental Station in late July 1984. The experiment was carried out in the middle of the sprout seedling plot. The experiment was designed by field comparison and divided into six groups. The first group with DC +500 v, the third group is DC -500 v, taking into account the impact of the electric field on the nearby seedlings in the second group for the isolation group; fourth, fifth group
