摘要 为研究元阳传统栽培品种和外来引入新品种对不同氮肥用量的响应,在不同的氮肥处理下,对元阳地区月亮谷(传统品种)和楚粳26号(新品种)的氮素吸收量、水稻稻瘟病病情指数及产量构成因素进行了分析研究。结果表明,随着氮肥投入量的增加造成月亮谷减产,并引发了稻瘟病,氮素的吸收、利用效率随氮肥投入量的增加而下降,处理2(7500kg/hm2有机肥)产量最高,分别比处理1(不施肥)、处理3(7500kg/hm2有机肥+75kg/hm2氮肥)、处理4(7500kg/hm2有机肥+150kg/hm2氮肥)增产14%,10%,11%。而对于楚粳26号,氮素用量最高的处理4(7500kg/hm2有机肥+150kg/hm2氮肥)相比处理1(不施肥)、处理2(7500kg/hm2有机肥)、处理3(7500kg/hm2有机肥+75kg/hm2氮肥)分别增产77%,46%,10%,氮素利用效率随氮肥投入量的增加呈上升状态。

Abstract: o study the effects of different nitrogen fertilizer use levels on local traditional and intro-duced rice varieties in Yuanyang terrace,the nitrogen uptake,diseased index and yield of Yuelianggu (traditional) and Chu 26(introduced) were analyzed in the different nitrogen treatments. The experi-mental results showed that,with the increase of nitrogenous fertilizer inputs,the yield of Yuelianggu declined,rice blast happened,nitrogen uptake efficiency and nitrogen utilization efficiency wentdown. The yield of treatment 2(7 500 kg/hm2 organic fertilizer) had raised 14%,10% and 11%,respectively,compared with that of treatment 1(without fertilizer),treatment 3(7 500 kg/hm2 or-ganic fertilizer+75 kg/ hm2 nitrogen fertilizer) and treatment 4(7 500 kg/hm2 organic fertilizer+150 kg/ hm2 nitrogen fertilizer).Meanwhile,the Chu 26 had positive responds to the exogenous ac-tive nitrogen. The yield of treatment 4(7 500 kg/hm2 organic fertilizer+150 kg/ hm2 nitrogen fertil-izer) had raised 77%,46% and 10%,respectively,compared with that of treatment 1(without fertilizer),treatment 2(7 500 kg/hm2 organic fertilizer),and treatment 3(7 500 kg/hm2 organic fertilizer+75 kg/ hm2 nitrogen fertilizer).The nitrogen utilization efficiency became higher along with the nitrogenous fertilizer inputs increased.
