摘要
针对我国北方水稻氮肥利用率低、土壤积盐严重的问题 ,对不同程度的盐碱地水稻生长性状进行分析 ,并利用氮素总量平衡原理 ,分别监测六种灌水技术条件下水稻全生育期内氮素的去向 ,进行定量分析计算 ,为我国北方盐碱地水稻生产提出了较为可行的参考依据 .
Aiming at the problem about the low utilized coefficient of nitrogen manure and serious accumulation of salt in north China, the physiological feature of rice in different saline-alkaline field has been analyzed and the direction in which nitrogen has gone is monitored and analyzed quantitatively in a growth period duration.
