杂交油菜三北98双株移栽试验效果分析

摘要

the experimental results showed that: three 98 hybrid rape seedling transplanting unit area under the condition of the same number of transplanting, double plant transplanting than plant transplanting yield, but the yield is not significant. The number of transplanting under different circumstances, more than the number of transplanting plant, plant yield than transplanting, yield is still not up to significant level, with two strains 4000 litters (8000 strains) should be /667m2, higher than the double strain 4500 litters (9000 strains) /667m2 density whether the production needs further testing; less than the number of transplanting to yield per plant. Single and double plant transplanting stage was the same.%文中的试验结果表明：三北98杂交油菜育苗移栽单位面积上移栽株数相同的情况下，双株移栽比单株移栽增产，但增产不显著，移栽株数不同的情况下，多于单株移栽株数的，比单株移栽增产，增产仍达不到显著水平，以双株4000窝（8000株）/667m2为宜，高于双株4500窝（9000株）/667m2为密度的是否增产有待于进一步试验；少于单株移栽株数表现为减产。单双株移栽生育期基本一致。
