, 2008 通过两室根箱栽培棉花新陆早13号实验,研究了磷酸二氢钾、植酸钠(Na-phytate)2种磷源形态对AM真菌Glomus mosseae接种效应的影响及棉花生长的影响。结果表明:在不施磷肥的条件下,接种Glomus mosseae真菌时,棉花的生长势没有显著差异,棉株地上部磷含量显著高于没有接种Glomus mosseae真菌的处理。施磷酸二氢钾时,接种Glomus mosseae真菌对棉花生长势起到显著的促进作用,棉株地上部磷含量也显著提高;施用植酸钠时,接种Glomus ...

, 2006 根据相关农业统计和农户调查资料,对新疆棉花生产中化肥施用与产出效率状况进行了分析。结果表明:近8 a来新疆棉田化肥投入量在400~450 kg/hm2之间徘徊。当前新疆棉田平均施用水平为429.1 kg/hm2,其中氮、磷、钾养分比例为1∶0.63∶0.027各地区棉田化肥分配很不平衡。棉田投入化肥的种类较单一,其中二铵为187.1 kg/hm2,占棉田化肥投入总量的44%,尿素为183 kg/hm2,占化肥总投入量的45%。新疆棉田化肥产出效率大都在2.9~3.7 kg/kg(棉花/化肥)之间 ...
