摘要
[目的]筛选适宜容县当地推广的半机械化直播水稻高产良种.[方法]结合当地地形地貌、气候、土壤等情况开展杂交水稻新品种半机械化直播栽培试验,对 6 个杂交水稻品种的产量、生育期、农艺性状表现等方面进行分析.同时,从稻田整理、品种选择、播种时间、田间管理等方面总结了水稻半机械化直播获得高产的栽培关键技术要点.[结果]试验结果表明:深两优 1173、香夏两优 8773 品种田间综合表现好,具有生育期适宜、抗性强、丰产性好等特点,适宜推广用于半机械化直播种植;原香优 361、丽香优纳丝品种产量稳定,可适当推广用于半机械化直播种植;鑫丰优 868、羽香优 058 品种不适用于半机械化直播种植.水稻半机械化直播获得高产的栽培关键技术要点包括精细整地,保证良好的稻田种植条件;选择适宜良种,筛选、处理种子;确定播种时间及播种量;做好田间管理,科学施肥、灌溉,及时防治病虫草害.[结论]深两优 1173、香夏两优 8773 水稻品种在容县半机械化直播栽培试验中表现优良,推荐在当地推广用于半机械化直播种植.
Abstract
[Objective]This study was conducted in order to select high yield semi-mechaniza-tional direct seeding rice varieties suitable for local promotion in Rongxian County.[Method]The semi-mechanizational direct seeding cultivation experiment of new hybrid rice varieties was carried out according to the local topography,climate,soil and other conditions,and the yield,growth pe-riod and agronomic characteristics of 6 hybrid rice varieties were analyzed.At the same time,the key cultivation techniques of semi-mechanical direct seeding for high yield of rice were summarized from the aspects of field preparing,variety selection,sowing time and field management.[Result]The test results showed that'Shenliangyou 1173'and'Xiangxialiangyou 8773'had good comprehen-sive performance in the field,and had the characteristics of suitable growth period,strong resistance and high yield,so they were suitable for promoting in semi-mechanical direct planting.'Yuanx-iangyou 361'and'Lixiangyounasi'varieties had stable yield,and semi-mechanical planting could be properly promoted.'Xinfengyou 868'and'Yuxiangyou 058'were not suitable for the promotion in semi-mechanical direct planting.The key techniques for high-yield cultivation of semi-mechanical direct seeding rice include fine preparation of field to ensure good growing conditions for rice growth;appropriate rice variety selection,seed screen and treatment;determination of appropriate sowing time and seeding rate;careful field management,scientific fertilization and irrigation;and timely control of insect pests,diseases and weeds.[Conclusion]The new hybrid rice varieties'Shenliangyou 1173'and'Xiangxialiangyou 8773'performed well in the semi-mechanizational direct seeding cultivation experiment conducted in Rongxian County,so they were recommended for exten-sion as the varieties in semi-mechanizational direct seeding production in this county.
