摘要
通过油菜不同密度免耕栽培与翻耕栽培试验对比 ,结果表明 :以 6 0 0 0株 / 6 6 7m2 免耕栽培的群体结构合理 ,经济性状好 ,产量高 ,效益佳。证明油菜免耕栽培是一项节本增效的有效措施。在土壤肥力水平较高。
The results from the experiment between different densities under no tillage system and ploughed system in rape indicated that 6000 plants/667m 2 under no tillage system had reasonable population structure, good economical characters, higher yield and better benefits, which showed that no tillage system was an effective way with lower cost and higher benefit. The technique can be popularized on the sandy loam soil and alluvial land with higher fertility.
