摘要
依据 1992年以来在贵州省罗甸县边阳镇的长期水保试验基地 9年的定位观测 ,证明植物篱 (绿篱 )逐步梯化技术有显著的水土保持效果 ,能使土壤侵蚀由传统的年均 43.2 t/ hm2迅速下降到 4t/ hm2 ,能增加水分年均保蓄量 36 0 m3/ hm2 ,使作物产量逐年增加。试验还表明 ,自然翻耕使坡度年均下降 1.1°,形成 17.1～ 2 0 .0 cm 高的梯埂。此项技术省时省资省劳 ,易操作易管理 。
According to the nine year data collected from the long term soil conservation experiment site since 1992, which located in Bianyang township of Luodian county of Guizhou province, the alley cropping technology integrated with terracing slopping land had significant impact on soil and water conservation. The average annual quantity of soil erosion declined from 43.2 t/hm 2 in traditional farming to 4 t/hm 2 in this technology on slopping land, and capacity of water holding increased 360 m 3/hm 2. Crop yield also increased yearly. The experiment also showed that the slope gradient decreased 1.1° per year and earth ladder of 17.1~20.0 cm formated along the hedgerows per year in average. This technology had the advances on saving time, saving money, saving manpower, and easy to be implemented and managed, so it is easy to be extended in proper mountainous areas.
