摘要
以中早 39、松雅早 1 号、陵两优 1785 等 9 个早稻品种为参试品种,以株两优 819 为对照品种(CK),在长沙县青山铺镇洪河村开展水稻品种的生态适应性鉴定与评价,通过对不同品种的生育期、抗病性、倒伏情况、农艺性状、经济性状以及产量的比较,筛选适宜推广种植的品种.试验表明:9 个品种中,松雅早 1 号产量最高,达 609.8 kg/667m2,比株两优 819(CK)增产12.53%,全生育期113 d;陵两优1785的产量第二,为584.8 kg/667m2,全生育期113 d;中安早7号的产量第三,为 573.2 kg/667m2,全生育期 114 d.相比之下,这 3 个品种丰产性好、生育期适中、综合性状表现较好,建议在长沙县地区进行推广种植.
Abstract
Nine early rice varieties,including Zhongzao 39,Songyazao 1,and Lingliangyou 1785,were used as test varieties,while Zhuliangyou 819 was used as a control variety(CK).The ecological adaptability identification and evaluation of rice varieties were conducted in Honghe Village,Qingshanpu Town,Changsha County.By comparing the growth period,disease resistance,lodging resistance,agronomic traits,economic traits,and yield of different varieties,favorable varieties were selected for promotion and planting.The test results show that among the nine varieties,Songyazao 1 has the highest yield,reaching 609.8 kg/667m2,with an increase of 12.53%compared to Zhuliangyou 819(CK)and a total growth period of 113 days.Lingliangyou 1785 has the second highest yield of 584.8 kg/667m2,with a total growth period of 113 days.Zhonganzao No.7 has the third highest yield of 573.2 kg/667m2,with a total growth period of 114 days.These three varieties have good yields,moderate growth periods,and excellent comprehensive character performance,so they are recommended for promotion and planting in Changsha County.
