选择8个不育系进行制种母本机插秧特性试验,设计不同用种量、不同秧龄期机插秧处理,研究对播始历期、主茎叶片数、群体苗数、穗粒结构及抽穗动态等特性的影响。结果表明:制种母本机插秧的播始历期比人工移栽延长,机插秧龄延长则播始历期明显延长,机插用种量对播始历期影响较小;母本机插秧的基本苗数、最高苗数、有效穗数、总颖花数均高于人工育秧移栽;机插秧与人工移栽、不同秧龄期处理、不同用种量处理的群体抽穗特性差异较小。根据母本机插秧特性的变化提出了杂交水稻制种母本机插秧的配套技术。
Eight male sterile lines were selected to test the characteristics of seedling transplanting. The seedlings were planted with different seedlings and different seedling age. The effects of seedling age, number of main stems, The dynamics of heading and other characteristics. The results showed that the sowing duration of seedling transplanting was longer than that of artificial transplanting and the prolongation of transplanting seedling age was significantly prolonged, The number of seedlings, the highest seedling number, the effective spike number and the total spikelet number were all higher than that of artificial seedling transplanting. The transplanting of seedlings and artificial transplanting seedlings with different seedling age treatments showed no significant difference in heading characteristics among different seed treatment groups. According to the characteristics of the transplanting seedlings of hybrid rice hybrid seedling planting techniques supporting the mother machine.
