油菜不同品种配方施肥比较试验

Fertilization Experiment on Different Rape Varieties

通过正交试验设计 ,对油菜不同品种进行配方施肥研究。结果表明 :相同处理对油菜不同品种的产量具有明显影响 ,黔油双低 2号和油研 6号单产分别为 76 .7～ 130 kg/6 6 7m2 和 86 .7～14 3.3kg/6 6 7m2 ;当采用小窝点播时 ,黔油双低 2号和油研 6号最佳的配方施肥比例分别为每6 6 7m2 施尿素 31.1kg和 2 6 .1kg、过磷酸钙 53.3kg和 4 0 .6 kg、氯化钾 12 .2 kg和 16 kg、硼砂 2 .7kg和 2 .7kg。

The result from the experiment designed according to orthogonal design principle showed that there was significant response to the different rape breed under the same treatment;The outputs of double low Qianyou 2 and Youyan 6 were 76.7～130kg/667m 2 and 86.7～143.3kg/667m 2 respectively.When hole sowed,the best fertilization ratios for double low Qianyou 2 and Youyan 6 were as follows:the application norm of urea was 31.1kg/667m 2 and 26.1 kg/667m 2;the superphosphat 53.3kg/667m 2 and 40.6 kg/667m 2;potassium chloride 12.2 kg/667m 2 and 16 kg/667m 2; the borax 2.7 kg/667m 2 and 2.7 kg/667m 2, respectively. The results indicated that the fertilization prescription dependson different varieties.
