| 摘 要： | 目的]研究油菜秸秆全量还田与移栽稻施氮量互作效应。方法]以早熟晚粳南粳44为试材，在油菜秸秆全量还田无害化处理下，探讨了不同施氮量与秸秆腐熟释氮对水稻群体建成的五作效应。结果]当全生育期纯氮施用量为300kg／hm^2，基肥、分蘖肥、促花肥、保花肥运筹比为4：6：5：5时，南粳44群体质量指标最为理想，产量超过9750kg／hm^2。结论]该研究为实现耕地的可持续利用提供了理论依据。

| Abstract: | Objective] The aim was to study interaction effects between returning total rape straw to field and nitrogen application rate in transplanted rice cultivation.Method] Taking early maturing japonica Nanjing 44 as material,interaction effects between different nitrogen application rates and rotten rape straw on rice population formation were studied by returning total rape straw to field.Result] When purity nitrogen was applied at the level of 300 kg/hm2 in the whole growth period,furthermore the proportio... |
