水稻施用三十烷醇—1后,植物体内碳氮代谢有很大的变化,氮素营养的吸收及光合作用的产物淀粉的积累量都有很大差异。1982年在水稻幼穗分化期(7月3日)和圆秆期(7月14日),用不同浓度的三十烷醇—1,喷雾法处理稻株,前者分三期取样进行分析;后者三次重复顺序排列,于7月19日取样测定叶鞘淀粉量的比值。根据水稻体内淀粉含量的多少,可间接推断出水稻氮素营养水 After applying triacontanol-1 to rice, the metabolism of carbon and nitrogen in plants changed greatly, and the absorption of nitrogen and the accumulation of starch, which is the photosynthesis product, all differed greatly. In 1982, the rice plants were treated with different concentrations of triacontanol - 1 and spray method in the panicle stage (July 3) and the round stem stage (July 14). The former was sampled in three phases for analysis. The latter three repeated order, sampling on July 19 to determine the amount of leaf sheath starch ratio. According to the amount of starch in rice body can indirectly infer rice nitrogen nutrition water
