| 摘 要： | 本文研究了不同绿肥在华北地区的越冬性及生长情况。结果表明:不同绿肥越冬性有显著差异,冬油菜越冬成活率最高,紫花苜蓿次之,剩余3种冬绿肥(二月兰、毛苕子、草木樨)较低;植被覆盖有助于减少土壤水土流失,冬油菜对土地的覆盖能力最强,紫花苜蓿和二月兰次之,毛苕子和草木樨最差;生物量调查结果表明,冬油菜的地上部生物量最大,紫花苜蓿和二月兰次之,毛苕子和草木樨最低。研究结果为绿肥在华北地区旱田的应用提供了参考。

Screening Test of Green Manure Varieties in Dry Fields in North China |
| |
| Abstract: | The overwintering characteristics and growth of different green manures in North China were studied in this experiment. The results indicated that there were significant differences in the overwintering properties of different green manures. The overwintering survival rate of winter rape was the highest, followed by alfalfa, while the remaining three winter green manures (February, Vetch, and Sweet Clover) were lower. Vegetation cover can help reduce soil erosion. Winter rape has the strongest ability to cover the land, followed by alfalfa and february orchids, while vetch and sweet clover are the worst. The biomass survey results showed that the above-ground biomass of winter rapeseed was the largest, followed by alfalfa and February orchid, and the lowest of vetch and sweet clover. The research results provide a theoretical basis for the application of green manure in dry fields in North China. |
