摘要
1983～1987年期间研究了甘蔗生长后期叶面喷施草甘膦、乙烯利等10种药剂对甘蔗生长、糖份积累等工农艺性状及某些生理特性的影响。结果表明,施草甘膦、乙烯利后蔗茎伸长速度比对照少0.17～0.84厘米/月,收获时单株绿叶数少1～2片。+3～+6叶鞘鲜重、含水率降低,此四项差异均达极显著水平,但它们对+1叶胞质酸、中性转化酶的相对活性和原料蔗产量的影响不显著。在工艺性状方面。草甘膦、乙烯利明显加快了甘蔗糖积份累速度,极显著地提高了甘蔗上半株的锤度和原料蔗品质(蔗糖份、纯度提高,还原糖降低),亩含糖量分别比对照提高46.2～52.1公斤和34.0～35.5公斤。草甘膦对蔗尖做种和宿根发株有一定不良影响,而乙烯利则明显改善了这两种性能。此外,硅酸钠也极显著地提高了甘蔗亩含糖量。其他药剂对甘蔗的上述性状无显著影响,本文未作详细报道。
In this paper,the author had been carrying the experiments with the chemical substances to stimulate the growth for several years.Its results show that there are some effects on the physiological characters and the yield, as well as the sugar quality.
