摘  要:
重庆地区中性紫色土属中钾少磷缺氮型。稻草还田可增加土壤养分贮备,维持 P、K 活性,但对当季小麦的影响则与配施化肥类型有关,配施 NK 或 NPK 小麦养分吸收和土壤对(?)季小麦供肥量减少,籽粒/秸秆比降低。稻草与 NP 配施对土壤和作物均有良好影响。为发挥稻草的培肥土壤和增产作用,必须根据土壤、秸秆和作物养分供需状况,调节养分的平衡供应。

摘  要:
In a field experiment carricd out in 1991-92 in Chongqing on ncutral purple soil deficent in N,marginal in P and moderately adequate in K,rice straw application was shown to help increase nutrient storage and maintain high levels of available P and K in the soil.Its effects on wheat yield,however,depended on the fertilizers appied in combination with it.Straw combined with NK or NPK reduced nutrient uptake by the crop,grain:straw (w/w)and the amount of nutrient supplied by the soil to the crop of the season.Straw combined with NP proved beneficial to both the soil and the wheat crop.
