摘要
To determine the fertilization effect of the rapeseed green manure Youfei1, we assessed soil physical and chemical properties and the yield of succeeding crop before and after planting Youfei 1. Compared with basal soil samples and controls,improvements were observed in the soil content of available N, P, K, and organic matter. The content of available K and organic matter increased significantly by17.99% and 25.45%. The soil pH did not change noticeably, but the soil bulk density decreased significantly by 22.55%. After planting Youfei 1, the yield of a succeeding rice crop increased significantly by 6.62% in two years. We conclude that planting Youfei 1 can help maintain and improve soil fertility and significantly increase the yield of succeeding crop.
研究了绿肥专用甘蓝型油菜品种——油肥1号翻压还田对土壤理化性质以及后茬作物产量的影响,初步探讨了该油菜品种的培肥效应。结果表明:与基础土样及对照处理相比,种植翻压油肥1号后,土壤中碱解氮、有效磷、有效钾及有机质含量均有所提高,其中有效钾和有机质含量增加较为显著,与基础土样相比,分别提高了17.99%和25.45%;土壤pH值变化不大,土壤容重下降明显,降低了22.55%;同时,种植翻压油肥1号对后茬作物水稻的增产效果显著,2年平均增产6.62%。由此可见,种植翻压油肥1号对维持和提高土壤肥效以及促进后茬作物增产的效果显著。
