施肥对香根草篱长势及护土保水效果的影响

Effects of Fertilization on Vetiver Grass Hedgerow Growth and its Water and Soil Conservation

连续 6年的试验结果表明 :施肥能加速香根草的生长 ,促进浓密的香根草篱的形成 ,对分蘖的影响达到极显著水平。施肥处理的土壤侵蚀总量、径流量、径流系数分别为无肥处理的 5 1.4 %、79.5 %和77.8% ,更快、更好地起到水土保持的作用。

The experimental results in successive 6 years showed that applying fertilizer could accelerate Vetiver grass growth and the formation of Vetiver grass hedgerow. The Vetiver grass hedgerow of being fertilized was more effective: on water and soil conservation the total amount of soil erosion, runoff amount and runoff coefficient accounting for 51.4%, 79.5% and 77.8% of no fertilization treatment respectively.
