【摘要】 以滨海稻区推广面积较大的超级稻品种"盐丰47"为试材,分别进行人工手插秧和机插秧两种不同移栽方式,调查其生育特性及经济效益,分析不同移栽方式对水稻生育进程及经济效益影响。结果表明:两种移栽方式相比,水稻茎蘖数、叶龄进程、干物质积累量、每公顷产值及成本均存在差异,机插秧较传统手插秧产值减少1 119.3元/hm2,节支3 410.6元/hm2,总体增加效益达2 291.3元/hm2,增幅达23%,机插秧移栽方式可以大大提高劳动生产率,降低生产成本,显著增加经济效益。更多还原

【Abstract】 Handy transplanting and mechanized transplanting were contrasted to research growing characteristics and economic benefits by using Yanfeng-47 as experiment material,analyzed effect of cultivated mode on growing characteristics and economic benefits in coastal rice planting area.The results indicated that some differences in stem tiller number,leaf-age-progress,dry weight accumulation,value and cost of per hectare,mechanized transplanting can reduce 1 119.3 yuan/hm2 than handy transplanting and cut expenditures 3 410.6 yuan/hm2,overall benefits were 2 291.3 yuan/hm2 and growth were 23%,mechanized transplanting makes for a tremendous rise in labour productivity,lower costs of production and increase economic efficiency.更多还原
