摘要
为了深度地开发丘陵旱坡耕地和有效地防止水土流失,自1984年以来开展了多熟作物覆盖,结合少耕的长期定位试验研究。三年的结果表明,在川中丘陵区酸性较强的旱坡地上,应用这一综合的配套技术措施,不仅可节省投资6.55％、增产正副产品7.14％、纯收益增值15.28％,而且还有改善土壤理化性状和保护土壤的生态效益。
In order to deep exploit the sloping land of hilly region in Sichuan Basin, the location experiment with multiple cropping and less tillage was conducted from 1984 to 1986. The results showed that this new comprehensive technique could not only reduce the agricultural investment of 6.55%, increase the crop yield of 7,14% and the net gain of l5.28%, but also had the betterment of chemical and physical properties and had the protective effect on soil ecological environment for the stronger acidic dry sloping land in Sichuan Basin.
