摘要
为筛选出熟期适宜、抗逆性好、产量高、米质优,综合表现突出,适合沿淮流域推广种植的节水抗旱稻新品种,以期指导广大农民科学种植管理,从而提高节水抗旱稻种植效益。根据沿淮流域节水抗旱稻生产实际,近两年引进了11个节水抗旱稻新品种进行对比筛选试验,从品种生育特性、主要经济性状、主要农艺性状、产量与田间自然发病情况等进行综合分析评价,从而筛选出适合沿淮流域种植的优质、高产、多抗节水抗旱稻新品种。试验结果表明,“旱优650”、“旱两优8200”的产量较高、农艺性状、抗性等综合性状表现较好,适宜在沿淮流域推广种植。初步筛选出了适宜沿淮流域种植耐旱、抗病虫、高产节水抗旱稻新品种。为提升节水抗旱稻增产潜力奠定了基础。
This study aims to screen out new water-saving and drought-resistant rice varieties with good stress resistance,high yield,excellent rice quality and outstanding comprehensive performances,which are suitable for riping-stage along Huai River basin,so as to guide a lot of farmers to plant and manage scientifically for improving the planting efficiency of water-saving and drought-resistant rice.Based on the actual production of water-saving drought-resistant rice along the Huaihe river basin,11 new water-saving drought-resistant rice varieties have been introduced and screened for comparison in the past two years.The new rice varieties with high quality,high yield,multi-resistance,water-saving and drought resistance suitable for planting along the Huaihe River basin were screened out on the basis of a comprehensive analysis and evaluation of growth characteristics,main economic traits,main agronomic traits,yield and natural incidence in the field.The results showed that“Hanyou 650”and“Hanliangyou 8200”had high yield,good agronomic characters and good resistance etc.,which were suitable for planting along Huai River basin.The screening of new rice varieties with drought tolerance,disease and insect resistance,high yield,water-saving and drought resistance will lay a solid foundation for increasing yield potential of water-saving and drought-resistant rice.
