| 摘 要： | 采用裂区试验方法。结果表明：喷洒后７ｄ，株高ＧＡ３处理极显著高于ＮＡＡ处理（Ｐ＜０．０１）。１００ｍｇ．Ｌ－１ＧＡ３１５．１０－３ｋｇ．ｍ－２处理互作效应显著（Ｐ＜０．０５）。ＧＡ３处理使干物质中ＣＰ含量上升，ＣＦ含量下降。ＮＡＡ处理则相反。ＧＡ３处理影响一、二茬草，ＮＡＡ处理影响第一茬草。１００ｍｇ．Ｌ－１ＧＡ３、１５．１０－３ｋｇ．ｍ－２处理组合显著提高ＤＭ产量（Ｐ＜０．０５）。

| Abstract: | The results show that after spraying 7 days, the effects on individual height were more significant than that of NAA (P<0.01). 100mg. L-1 GA3 and 15.10-3kg. m2 treated took cooperative effects significantly (P<0.05). Sudangrass treated with GA, has an increase in crude protein (CP), but a decrease in crude fiber (CF) and that treated with NAA is to the contrary. GA3 mainly influenced the yield of DM and CP of grass at the lst and 2nd cutting time while NAA at the lst. The effect of 100mg. L-1 GA3 and 15. 10-3kg. m-2 significantly increased DM yield (P<0.05). |
