1972年秋季我们进行有机砷农药“稻脚青”在水稻上去雄作用的探讨,供试品种为大田生产用的“农红73”(6月28日播),“京引15”(7月10日播),“广陆矮4号”(7月25日播),于8月25日亩喷1.5%稻脚青溶液150～200斤(代号处理Ⅰ,小区面积0.003亩),另在9月8日和9月11日各喷射一次(代号为Ⅱ、Ⅲ),此外,还对单丛和多丛稻株喷射,并喷有1%浓度的,以作辅助试验。 In the autumn of 1972, we explored the effect of organic arsenic pesticide “Atractylodes japonica” on rice. The tested varieties were “Red Red 73” (sown on June 28), “Jingyin 15” (July 10 on the broadcast), “Guang Lu short 4” (July 25 broadcast), on August 25 acres spray 1.5% rice paddy green solution 150 to 200 pounds (code-named treatment Ⅰ, plot area 0.003 acres), the other in September 8 and September 11 each spraying once (code Ⅱ, Ⅲ), in addition, the single plexus and multi-cluster rice plants sprayed and sprayed with 1% concentration, as a supplementary test.
