Abstract

Abstract:

【Objective】Our aim is to investigate the differences in response of grain yield, nitrogen absorption and utilization toFACE (atmospheric CO₂ concentration increase) of different rice varieties. 【Method】Six rice varieties, including conventional japonica rice, hybrid indica rice, and conventional indica rice, were used to study the effects of free-air CO₂enrichment (FACE) (atmospheric CO₂ concentration increase) on the nitrogen absorption, utilization, and yield of different types of rice.【Result】1) FACE treatment dramatically increased rice yield by 24.17% on average and the maximum increment was observed in conventional indica rice. Compared with other types of rice varieties, hybrid indica showed the highest grain yield under both FACE and control (CK) treatments. 2) Panicle number was significantly improved in FACE treatment with conventional japonica rice varieties having the maximum increment.Spikelet number per panicle was significantly improved in hybrid and conventional indica rice varieties in FACE treatment. 3) The nitrogen absorption(NA) and nitrogen use efficiency for grain yield (NUEg) were significantly higher in FACE treatment than those in CK treatment. The average increase of NA was 21.23% with the maximum increment in hybrid indica rice varieties. Compared with other rice varieties, conventional indica rice varieties had the highest NA both in FACE and CK treatments. The average increase of NUEg was 7.33% with hybridindica rice varieties enjoying the maximum increment. The hybrid indica rice varietieshad the highest NUEg in FACE treatment and in CK treatment, respectively.4) Nitrogen content was decreased in FACE treatment with the average decrease of 0.105%, amongwhichthe maximum decrease was observed in conventional japonica rice. Dry matter weight was extremely and significantly increased in FACE treatment. The average increase of dry weight was 23.95% with the maximum increment in conventional indica rice varieties. NA of single panicle was significantly improved in FACE treatment with the average increase of 10.79% in conventional indica rice varieties and 13.93% in hybrid indica rice varieties, but NA of single panicle was decrease by 9.60% in conventional japonica rice. FACE treatment significantly increased rice NA intensity with an average increase of22.29% and the maximum increment was observed inhybrid indica rice varieties. The growth duration was not influenced by FACE treatment in all rice varieties. NAs of stem, leaf and panicle were significantly higher in FACE treatment than in CK treatment with the highest increase of 51.86% in leaf. The largest increase of NA was observed in hybrid indica rice. NA in different rice growth stageswassignificantly improved with the maximum increment of 108.90% during heading-maturity. The maximum increment of NA from heading to maturity was observed in hybrid indica rice varieties. 5) Effects of dry matter weight, NA per panicle, NA intensity, NA of panicle and NA from heading to maturity on NA at maturity were greater thanthose of nitrogen content, panicle number, growth duration, NAA of leaf, stem andsheath, NAA during transplanting-tillering and tillering-heading. 6) Partial productivity of nitrogen fertilizer (PFP_N) was significantly improved in FACE treatment with an average increase of 24.16% and the maximum increment in conventional indica rice. NAA per 100 kg grains was significantly reduced in FACE treatment with an average decrease of 4.7%.The maximum decrease of NAA per 100 kg grains was observed in conventional indica rice varieties.【Conclusion】The results indicated that FACE could markedly increased both grain yield and nitrogen use efficiency in all rice varieties, but theincreases variedwith the variety types.

摘要： 目的探明不同类型水稻品种产量和氮素吸收利用对FACE(大气CO₂浓度增高)响应的差异。方法以常规粳稻、杂交籼稻、常规籼稻共6个品种为供试材料,研究FACE对不同类型水稻产量、氮素吸收利用的影响。结果 1）FACE处理极显著提高了水稻产量,平均增加24.17%, 常规籼稻增幅最大,FACE和对照均以杂交籼稻最高;2）FACE处理显著增加了单位面积穗数,常规粳稻增幅最大,并显著增加了杂交籼稻和常规籼稻每穗粒数;3）FACE处理显著提高了成熟期吸氮量和氮素籽粒生产效率,成熟期吸氮量平均增加21.23%,杂交籼稻增幅最大, FACE和对照均以常规籼稻最高;氮素籽粒生产效率平均增加7.33%,杂交籼稻增幅最大,FACE和对照均以杂交籼稻最高。成熟期吸氮量对产量促进作用略大于成熟期氮素籽粒生产效率;4）FACE处理降低了植株含氮率,成熟期平均下降0.105个百分点,常规粳稻降幅最大。FACE处理极显著提高植株干物质量,成熟期平均增加23.95%,常规籼稻增幅最大;FACE处理显著提高常规籼稻和杂交籼稻成熟期单穗吸氮量,分别增加10.79%、13.93%,但常规粳稻下降了9.60%;FACE处理显著提高了成熟期群体吸氮强度,平均增加22.29%,杂交籼稻增幅最大。FACE处理对水稻全生育期天数无显著影响;FACE处理显著提高茎鞘、叶片、穗各器官吸氮量,叶片增幅最大,平均增加51.86%,杂交籼稻增幅最大;FACE处理显著提高了不同生育阶段吸氮量,抽穗-成熟阶段增幅最大,平均增加108.90%,杂交籼稻增幅最大;5）植株干物质量、单穗吸氮量、吸氮强度、穗吸氮量、抽穗-成熟阶段吸氮量对成熟期总吸氮量的促进作用分别大于植株含氮率、单位面积穗数、生育天数、茎鞘叶吸氮量、移栽-分蘖和分蘖-抽穗阶段吸氮量;6）FACE处理显著提高了氮肥偏生产力,降低了每百千克籽粒需氮量,前者平均增加24.16%,常规籼稻增加最多;后者平均降低4.7%,常规籼稻降幅最大。结论 FACE处理可显著提高水稻产量和氮素吸收利用效率,但品种间差异较大。
