为探明施钙与覆膜栽培对南方典型缺钙红壤(第四纪红土发育而成)花生氮、磷、钾吸收分配的影响,本试验以大籽品种湘花2008为材料,设置3个基施钙肥梯度(不施钙、每公顷施钙肥375kg、每公顷施钙肥750kg,分别标记为Ca0、Ca375、Ca750)和2种栽培方式(露地OF与覆膜栽培PF),采用土柱栽培,测定花生植株氮、磷、钾素含量、积累与分配特性。结果表明:随施钙量增加,花生叶、茎秆、根、果针、果壳氮素积累和分配率显著降低,而籽仁的氮素积累量和分配率、植株总氮素积累量提高,覆膜栽培降低叶和果针氮素分配率。增施钙肥有利于花生籽仁磷素的吸收积累、提高其分配率,但显著降低叶、茎秆、根系、果针、果壳磷素...

The effects of calcium application and plastic film mulching cultivation on accumulation,distribution and utilization efficiency of N,P,K in peanut(Arachis hypogaca L.)were investigated in red soil of southern China under calcium deficiency. Large seed variety Xianghua 2008 and the typical red soil under calcium deficiency were used as material for the soil column experiment from June 2014 to October 2015. Different calcium fertilizer gradi-ents and two cultivation methods(open field and plastic film cultivation)were used in this experiment including no calcium(Ca0),medium calcium fertilizer(C...
