| 摘 要： | 通径分析表明，协优５７产量构成４要素对产量的通径系数均为正值，其中有效穗及每穗总粒数较大。协优５７１．０５万ｋｇ／ｈｍ２产量结构应该是：有效穗２５５～２８５万／ｈｍ２，每穗总粒数１７０～１８０，结实率８３％～８５．０％，千粒重２７ｇ。在栽培上重点做到培育壮秧，控制无效分蘖，提高成穗率

| Abstract: | The results of path coefficient analysis showed that:its path coefficient of the four factors of yield formation was positive numbers to yield,and numbers of the effective spike and the grain per panicle were the most important.the yield structure with 10 500kg/hm 2 yield should be:effective spikes were 2 250 000 2 850 000/hm 2,the grain per spike were 170 180,the rate of seed setting was 83 85%,and the weight of 1 000 grain was 27g.In cultural,it should be:to control invalid tillers by breeding strong seedling,increase the rate of bearing tiller. |
