| 摘 要： | 1981-1986年在黄潮土上的小麦-玉米肥料定位试验,对肥料用量、作物吸收量和土壤养分积累量的回归分析结果:化肥N和有机肥N有8.76%和42.54%进入土壤N库;化肥P和有机肥P有17.61%和17.20%进入土壤速效P库;化肥K和有机肥K有4.5%和2.3%进入土壤速效K库.化肥对土壤有机质含量略有增加趋势,有机肥对补给土壤P、K养分,改善土壤物理性状有明显效果.有机无机配合施用具有培肥、增产两方面的作用.

| Abstract: | The regression analysis results of raft of ferrtilizer,amount uptaken by crops and accumulation of soil nutrients in the localized trial of fertilizers on wheatcorn on yellow fluvo-aquic soils during 1981-1986 showed that 8.76% of chemical fertilizer-N and 42.54% of organic fertilizer-N entered into soil N pool,17.61% of chemical fertilizer-P and 17.20% of organic fertilizer-P into soil available P pool,and 4.5% of chemical fertilizer-K and 2.3% of organic fertilizer-K into soil available K pool.Chemical fertilizers tended to increase in organic matter content of the soils,While significantly good effect of organic fertilizers was found on supplementing soil nutrients such as P and K and improving soil physical properties.Combined application of chemical and organic fertilizers was effective both in promoting soil fertility and raising crop yield. |
