2.超高产途径(1)发挥个体优势,适穗大穗夺高产“秀优5号”在采用稀植单本插的条件下其个体优势更能发挥,单株平均有效穗可达13.4穗,每穗总粒数可达240.1粒。从移栽和直播稻不同产量层次田块穗粒结构汇总分析,主要以适穗大穗获得高产。移栽稻倾向适穗大穗,直播稻倾向足穗大穗更 2. Super-high-yielding pathway (1) to play an individual advantage, panicle big spike yield high yield “Show excellent 5” in the use of sparse planting single insert under the conditions of their individual advantages to play more, the average effective panicles per plant up to 13.4 , The total number of grains per spike up to 240.1 tablets. From the transplanting and direct seeding rice fields at different yield levels of grain structure of a summary analysis, mainly in panicle ear to obtain high yield. Transplanting rice tend to spike large panicle, direct seeding rice tend to foot panicle spike more
