2010年晚季,广东省农科院水稻研究所和省农机推广站人员在省水稻所白云试验基地以常规超级稻品种合美占为试材,对水稻机械插秧、抛秧和人工插秧3种移植方式的生育特性及产量进行了分析比较。结果表明:①机械插秧的生育期比人工插秧、抛秧延长3d,人工插秧与抛秧的生育期相同。②机械插秧前期生长较缓慢,表现出分蘖增长较慢、个体和群体叶面积较小、个体和群体干物质积累较少,到生育后期,机械插秧略显优势。③在高地力、土层深厚的稻田,移栽密度为1.5873万科/亩的条件下,机械插秧、人工插秧和抛秧3种移植方式的产量构成因素差异不明显,因而产量差异不显著。 In the late 2010, the Rice Research Institute of Guangdong Academy of Agricultural Sciences and provincial agricultural extension station personnel in the Baiyun test base of the provincial rice to conventional super-varieties of rice combined accounted for the test material, rice mechanical transplanting, throwing and artificial transplanting three Fertility characteristics and yield of the transplanting method were analyzed and compared. The results showed that: (1) The growth period of mechanical transplanting was longer than that of artificial transplanting and throwing seedlings, and the growth period of artificial transplanting and throwing transplanting was the same. ② The growth of mechanical transplanting is slow at early prophase, showing slower growth of tillers, smaller leaf area of ​​individuals and groups, less accumulation of dry matter of individuals and groups, and mechanical transplanting is slightly superior to the later growth period. ③ Under the conditions of high fertility and deep soil layer, the transplanting density was 1.5873 million families / mu, there was no obvious difference in yield components among the three transplanting methods of mechanical transplanting, artificial transplanting and throwing transplanting. Therefore, the yield difference was not significant.
