摘要
[目的]研究青海东部农业区春油菜生产和肥料施用状况。[方法]应用随机抽样法对青海东部农业区春油菜养分管理技术的现状进行调查。[结果]该地区种植春油菜的66%左右农户获得的春油菜产量处于适中水平,50%左右农户氮肥用量基本合理,50%以上农户磷肥用量偏低或很低,而钾肥用量极低,中微量元素肥料的投入基本为空白。[结论]通过宣传,加深农户对春油菜使用磷肥、钾肥及中微量元素肥料重要性的认识。
[Objective]Production and fertilizer application status of spring oilseed rape in eastern Qinghai Province agriculture area were studied.[Method]Applying the method of random sampling,current situation of spring oilseed rape nutrient management technique in eastern Qinghai Province agriculture area was surveyed.[Result]66% spring oilseed rape farmer got moderate level yield.50% spring oilseed rape farmer applied reasonable nitrogenous fertilizer.50% spring oilseed rape farmer applied low or very low phosphate fertilizer.Potash fertilizer amount was extremely low,and trace elements fertilizer amount was probably blank.[Conclusion]It was needed to reinforce the importance about phosphate fertilizer,potash fertilizer,trace elements fertilizer for the farmers through publicity.
