　　在冷浸田上研究施用化肥与不施化肥以及在施用化肥的基础上增施单一的中、微量元素和复合微量元素对冷浸田水稻产量和养分吸收的影响。经2年的研究结果表明：全部施肥措施均能有效地提高水稻对养分的吸收和水稻产量水平。施肥比不施肥（ CK）增产5．8％～40．7％。在100％化肥的基础上，增施锌和硫肥，水稻的产量增加5．3％～26．7％。增施锌肥，氮、磷、钾的利用率增加明显；但增施硫肥，效果不明显。综合产量和对养分利用率增施量微量元素的效应为：100％化肥＋硫酸锌＞100％化肥＋氧化锌＞100％化肥＋硫磺＞100％化肥＞对照（不施肥）。

Two years'field experiments for the application of different chemical fertilizers ( CF) and the added application of middle and micro-elemental fertilizers were conducted in cold waterlogged paddy filed to study their effects on rice yield and nutri -ent uptake .The results indicated that:as compared with CK ( without fertilization ) , all fertilization treatments effectively increased the uptake of rice to nutrients and rice yield , and the yield-increasing rate was 5.8%~40.7%.On the basis of applying 100%chemical fertilizer, the added application of Zn and S fertilizers could further increase rice yield by 5.3%~26.7%.The further a-nalysis showed that the added application of Zn fertilizer could significantly improve the utilization rates of N , P and K fertilizer . However the added application of S fertilizer did not obviously enhance the utilization rates of N , P and K fertilizer .Taking the yield of rice and utilization rate of fertilizer into account , the treatment of 100%CF+ZnSO4 was the best , followed by the treatments of 100%CF+ZnO, 100%CF+S, 100%CF and CK one by one .
