施氮量、播期、密度对扬麦16产量影响效应

The Effect of Nitrogen Amount,Sowing Date and Density on the Yield of Yangmai 16

通过随机区组试验,研究了施氮量、播期和密度对扬麦16产量的影响效应。研究结果表明:施氮量、播期、密度、施氮量与播期互作、密度与播期互作均对产量有极显著影响。在本试验条件下,11月3日播种、150万/hm2密度、240kg/hm2施氮量,最有利于实现扬麦16高产。

The effect of nitrogen amount, sowing date and sowing density on the yield of Yang- mai 16 is studied through the random area group experiment. The results show that the nitro- gen amount, sowing date, density, the interaction between nitrogen amount and sowing date, and the interaction between density and sowing date all have significant effect on the yield of Yangmai 16. So Yangmai 16 has the highest yield on the sowing date of November 3rd, with the sowing density of 1, 500, O00/hm2and the nitrogen amount of 240 kg/hm2.
