不同施肥量·密度和行距对油研九号产量的影响

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 。

Effects of Fertilization,Row Width,Planting Density on Rape Variety——Youyan No.9 Yield

Study results showed:there were very significance different effect of row width,planting density,interact of row and planting density on rape variety--Youyan No.9 yield,there were no significance difference between fertilizations.10.87% of yield was increased in the planting density from 12×10 4 plant/hm 2to 9×10 4?plant/hm 2;5.71%,in width-narrow to equal row.In the planting density of 12×10 4?plant/hm 2 with equal row,the yield increased by 12.30%.High-yielding cultivation measures of Youyan No.9 were:the planting density was 12×10 4plant/hm 2,width-narrow row planting was used, the amount of nitrogen fertilizer was 270?kg/hm 2;P 2O 5,180 kg/hm 2;K 2O,225 kg/hm 2 and B,22.5 kg/hm 2,and the highest yield reaches to 3?738.90 kg/hm 2.
