摘要
根据湖南省农技推广总站的安排部署,为更好地推广优质高产粳稻品种,缓解种子的供求矛盾,对新引进扬粳4227、甬优5550、甬优1540、甬优4540、春优84、天优华占(CK)等6个粳稻品种进行了品比试验。结果表明:春优84和甬优4540除分蘖的略低于天优华占(CK)外,在植株长势、株型、产量表现、抗病能力、抗倒伏性等方面,均不同程度地优于或等于天优华占,二者可在宁远县烟稻轮作的晚稻田上生产示范种植。
According to the arrangement of Agricultural Technology Extension Station of Hunan for the better promotion of high-quality and high-yield Japonica rice varieties to alleviate the contradiction of supply and demand of the seed, new Japonica rice varieties Yangjing 4227, Xiushui 09, Yongyou 5550, Yongyou 1540, Yongyou 4540, Chunyou 84 and Tianyouhuachan（CK） were introduced and compared in this test. The results showed that the Chunyou 84 and Yongyou 4540 were better in different degrees than or equal to the Tianyouhuachan（CK） in plant growth, plant type, grain yield, disease resistance and lodging resistance, except slightly lower in the tillering; and both of them could be grown as production demonstration in late-rice fields of tobacco-rice rotation areas in Ningyuan.
