硼在油菜正常生长过程中必不可少,但是施硼不当会导致油菜产量降低,为了使直播油菜在不同时期合理施硼以达到增加产量的效果,采用不同时期针对性施硼和清水喷洒方式进行对比试验。结果表明:针对不同时期合理施硼比清水喷洒组产量增加250.5~470.5 kg/hm2,且油菜经济性状明显提高,植株菌核病感染率有所下降,存在显著差异。 Boron in the normal growth of rapeseed is essential, but improper application of boron will lead to reduced rapeseed production, in order to make direct seeding rape in different periods of boron to achieve the effect of increasing production, the use of targeted boron and water spray at different times Comparative Test. The results showed that the yield of S. sclerotiorum decreased 250.5-470.5 kg / hm2 and the economic traits of rapeseed increased obviously, which was significantly different from that of the control group.
