1956年天津第一农药生产合作社合成了α-萘乙酸,并制成其钠盐后,曾分送许多单位作田间试验,在1957-1958年作出了一些对农作物生长和增产作用的初步结果,现在综合报导如下:广东杨村农场用α-萘乙酸钠在水稻播种前浸种12小时,结果提早三天发芽,发芽率也提高。经过浸种的稻苗还有抗早性能。天津六里台农场报导,用10ppm 浓度浸稻苗根二小时,再进行插秧,秧苗返
In 1956, Tianjin No.1 Pesticide Production Cooperative synthesized α-naphthaleneacetic acid and made its sodium salt. After many units were distributed for field experiments, some preliminary results on crop growth and yield increase were made in 1957-1958. Now comprehensively summarized as follows: Guangdong Yangcun farms with sodium α-naphthalene soaked in rice before sowing for 12 hours, the results of three days earlier germination, germination rate also increased. Seed soaked rice seedlings also have anti-early performance. Tianjin Liulitai farms reported, with 10ppm concentration of rice seedlings immersed in two hours, and then transplanting, seedlings back
