摘    要:红壤长期连作花生产生严重连作障碍,影响花生生产。本试验研究磷化工废弃物在缓解花生连作障碍上的效果,采用磷石膏与化学氮肥、化学磷肥、化学钾肥不同比例制成磷石膏专用复混肥,施用于中科院江西红壤生态试验站花生连作田块,考察对红壤养分及花生生理性状及产量的影响。结果表明: 施用含磷石膏专用复混肥比使用常规复合肥处理增产3.5-45.1%,土壤中的全氮、速效氮、和速效钾含量升高,植株全N、P、K含量均有提高,施用磷石膏专用肥可以有效缓解红壤地区花生连作障碍。

关 键 词:红壤地区  磷石膏  花生  连作障碍

Abstract:Peanut production has been severely repressed by sick soil resulting from long term monoculture of peanut in red field in Jiangxi. Phosphorus chemical waste solid, phosphogypsum , wasinvestigated to alleviate the sick soil due to continuous monocropping of peanut in red soil. Mixture of phosphogypsum with chemical nitrogen, phosphate and potassium fertilizer in a different ratio were applied to peanut plots in Jiangxi Red Soil Ecology Experimental Station, China Academy of Sciences to assess their effect on nutrients of red soil and peanut yield and physiological and biochemical properties. The results showed that peanut yield in treatment of phosphogypsum-containing mixed fertilizer was increased by 3.5-45.1% compared to comventional fertilizer treatments.The soil total nitrogen, available nitrogen and potassium was increased, while plant total N, P, K were raised compared with control.This indicated man-made phosphogypsum-containing mixed fertilizer would effectively relieve sick soil in red soil in the region of continuous monocropping of peanuts.
Keywords:Phosphogypsum  Red soil  Peanut  Continuous monocropping
