赤霉素能否促进块根类作物——甘薯增产,以及使用的浓度和方法等问题,我们于一九五九、一九六○两年进行了试验研究,并已获得一定的增产效果,兹扼要报导如下。 一 赤霉素喷叶处理对甘薯块根的产量和地上部分的影响 (一)对甘薯块根产量的影响 在甘薯扦插后三十九天,以百万分之零点五、十、二十、四十和一百等五种不同浓度的赤霉素水溶液(对照用同量蒸馏水)喷叶一次,平均每株喷四毫升左右,结果表明处埋浓度过低则效果不明显;

Gibberellin can promote root tuber crops - sweet potato yield, as well as the use of the concentration and method of such issues, we in 1959,1960 years conducted a pilot study, and has been to increase the yield effect, we have The main report is as follows. Effects of gibberellic acid sprayed leaves on yield and aerial parts of sweet potato root tuber (a) Effects on yield of sweet potato tuber root Thirty-nine days after sweet potato cuttings, Ten and one hundred five different concentrations of gibberellin aqueous solution (control with the same amount of distilled water) leaf spray, an average of about four milliliters of spray, the results show that the concentration is too low buried effect is not obvious;
