摘 要: | 研究结果表明,退化天然草地通过补播,鲜草产量每公顷提高68%,经t检验差异显著(p<001)。施肥试验组与对照比较,各处理差异极显著(p<001),其中每公顷施1875kg尿素效果最佳。刈割试验与对照比较差异极显著(p<001),鲜草产量每公顷提高611%。

Abstract: | The Studying results indicated that through reseeding on those degenerated rangelands,the yield of fresh grass weight had gained an increase of 68%,the differences then showing at high significance level (p<001)When the fertilizer application trial group was in contrast with the control,the differences between each treatment group would be clearly showing their highest level statistically (p<001)From among,the effect of urea treatment (1875 kg/hm2) was shown up to the highest. In the next place,when the cutting treatment was compared with the control,the statistical difference would be manifested at the top level statistically with p<001,that means,the fresh weight increase was gained in a percentage of 611%。 |
