目前有不少国家利用物理效应来增加农作物产量和改善品质,取得了明显的效果。电效应:科学家研究发现,给植物施加微弱电流,可以加快植物的新陈代谢,增强光合作用,从而增加产量。原苏联专家用电流处理西红柿,结果增产10～20％,果实中含有的维生素C也增加。美国采用人造电场种作物,可使棉花增产30％以上,使黄瓜,西红柿增产1倍以上。匈牙利利用静电处理作物种子,使蔬菜增产20～25％,饲料作物增产15～20％。磁效应:日本利用比地球磁场高一万倍的磁场和电磁场处理大豆和菜豆种子,使大豆发芽提早几天,成熟期也提早10多天;菜豆也提早10多天成熟。光效应:专家们发现,植物不仅具有趋光性,而且对光有选择性,不同植物喜欢不同颜色的光。如小麦、水稻喜欢红色和橙黄色的光,如照射这样的光,能使其生长
At present, many countries use physical effects to increase crop yield and improve quality, and have achieved remarkable results. Electrical Effects: Scientists have found that applying weak currents to plants can speed plant metabolism and increase photosynthesis, thereby increasing yields. The original Soviet experts treated tomatoes with current, the result of an increase of 10 to 20%, the fruit contains vitamin C also increased. In the United States, man-made electric field crops are used to increase the yield of cotton by more than 30%, so that cucumber and tomato yield more than double. Hungary uses the electrostatic treatment of crop seeds, increasing the yield of vegetables by 20-25% and that of fodder crops by 15-20%. Magnetic effect: Japan uses a magnetic field of 10,000 times higher than the Earth’s magnetic field and electromagnetic field treatment of soybean and bean seeds, so that soybean germination a few days earlier, the maturity of more than 10 days earlier; beans also mature more than 10 days earlier. Light Effects: Experts have found that plants are not only phototropic but also light selective, and different plants like light of different colors. Like wheat, rice like red and orange light, such as light such as irradiation, can make it grow
