国外许多研究证明:小剂量电离辐射对生物的生长、发育、营养利用、生殖、抗辐射和感染以及寿命的延长是有益的,并已广泛用于生产实践。如苏联用小剂量电离辐射处理作物,谷物和豆类作物增产10—20％,蔬菜增产20—30％,马铃薯增产15—20％。我们对佛罗里达和凤尾菇两个栽培菌种,用~(60)Co—γ射线照射。剂量率为1.5戈瑞/分。每个菌种作5个剂量处理,分别为1.9、3.8、5.7、7.6、9.5戈瑞,三次重复,另设对照。照射
Many foreign studies have proved that low dose ionizing radiation is beneficial to the growth, development, utilization of nutrients, reproduction, radiation and infection, as well as to the extension of life expectancy and has been widely used in production practice. For example, the Soviet Union used small doses of ionizing radiation to treat crops, cereals and legume crops by 10-20%, vegetables by 20-30% and potatoes by 15-20%. We cultivated two cultivated species of Florida and Pleurotus ostreatus with ~ (60) Co-γ rays. The dose rate is 1.5 Gy / min. Each strain for 5 doses, respectively, 1.9,3.8,5.7,7.6,9.5 Gy, repeated three times, another set of controls. Irradiation
