据报道,在大豆开花初期至成熟期之间,每亩施PGR—1有效成分21.42克可提高产量28％。据此,我们与南开大学元素所协作,并在该所陈茹玉教授的指导下,于1978—1979年进行了试验、示范。 PGR—1的化学名称为:3—(2—吡啶基)丙醇。
It has been reported that 21.42 grams of PGR-1 active ingredient per mu per acre can increase the yield by 28% between the initial flowering stage and the maturity stage of soybean. Accordingly, we collaborate with the elements of Nankai University and under the guidance of Professor Chen Ruyu, conducted experiments and demonstrations in 1978-1979. The chemical name of PGR-1 is: 3- (2-pyridyl) propanol.
