研究表明 ,密度、行距和密度与行距的互作对油研九号产量的影响达到极显著水平 ,而施肥量间产量差异不显著。密度 12万株 /hm2 比 9万株 /hm2 的增产 10 .87% ,宽窄行比等行距的增产 5 .71% ,增产均达极显著水平 ;密度 12万株 /hm2 时宽窄行处理比等行距处理增产 12 .3 0 % ,增产达极显著水平 ;密度 9万株 /hm2 时宽窄行处理与等行距处理间产量差异不显著。油研九号高产栽培措施为密度 12万株 /hm2 ,宽窄行栽植 ,施纯氮 2 70kg/hm2 ,P2 O5180kg/hm2 ,K2 O 2 2 5kg/hm2 ,硼砂 2 2 .5kg/hm2 ,最高产量可达3 73 8.90kg/hm2 。
The results showed that the effects of density, row spacing, density and row spacing on the yield of Yanyan9 reached a very significant level, but the difference in yield between the two treatments was not significant. The density increased by 10.77% with the density of 120000 / hm2 over 90000 / hm2, and the yield increased by 5.71% at the width and breadth of rows with an extremely significant increase in production; The row spacing treatment increased by 12.3%, and the yield increased to a very significant level. There was no significant difference in the yield between the width and width rows at the density of 90,000 / hm2. The high-yielding cultivating measures of Yanyan No.9 were density 120,000 / hm2, broad-width and narrow-row planting, application of pure nitrogen 2 70kg / hm2, P2 05180kg / hm2, K2O225kg / hm2, borax 22.5kg / hm2, Up to 3 73 8.90kg / hm2.
