Screening of Rice Variety Suitable for Direct Seeding in Hilly and Mountainous Area
摘要
Abstract
[Objective] To screen the rice variety suitable for direct seeding in hilly and mountainous area.[Method] A total of 14 varieties of hybrid indica rice,conventional indica rice,japonica hybrid rice and conventional japonica rice were used as the test materials,artificial direct seeding was adopted to investigated the effects on agronomic characters at different growth periods.Sampling and yield detecting were carried out at mature stages.And data obtained were analyzed.[Result] The yields of hybrid indica rice Wanyou 66,Wanyou481,Japonica hybrid rice 1503,1505,and conventional Japonica rice Zhongke 8 were all more than 10 500 kg/hm2.Among them,yield of Wanyou 66 was the highest,reaching 11 274 kg/hm2,followed by Wanyou 481 (11 134.5 kg/hm2).They were all suitable for direct seeding and could be used for large-scale extension.[Conclusion] Comprehensively,Wanyou 66 and Wanyou 481 could be selected if using artificial harvesting;and Zhongke 8,1505 and 1503 should be selected if using mechanical harvesting.关键词
