摘要: 试验以垦鉴稻6号为供试材料,研究了不同氯肥处理对其生长发育、产量及氯肥利用率的影响,以期为氯肥的合理施用提供依据。结果表明:优化施肥+腐殖酸处理(T3)与不施氯肥相比,垦鉴稻6号的叶龄指数、茎数不同程度的增加,而株高降低;T3处理下,其分蘖成德率、单位面积德数、穗粒数、千粒重、结实率均有昕增加。氯肥农学利用率及偏生产力最高,分别为23.4%,46.7kg/kg。T3施肥处理下垦鉴稻6号产量最高,为8422.5kg/hm^2。

Abstract: In order to provide a basis for the rational application of terfilizers tor Kenjiandao 6, the ettects of ditterent nitrogen terfilizer treatments on its growth, development, yield and nitrogen use efficiency were studied. The resuhs showed that the opfimmn tertilization + hunfic acid treatment (T3), compared with no nitrogen terfilizer, increased the leaf age index and stem number of Kenjiandao No. 6, while the plant height decreased. Under T3 treatment, the tiller heading rate, number of ears per unit area, grain number of ears, 1000-grain weight and seed setting rate were all increased. The highest utilization rate and partial productivity values were 23.4% and 46.7%, respectively. The yield of Kenjiandao No. 6 was the highest at 8 422.5 kg/hm^2 under terfilization + hmnic acid treatment (T3).
