2021年互助县蚕豆化肥利用率田间试验

Field Experiments on Fava Bean Fertilizer Utilization Rate in Huzhu in 2021

为探索互助县蚕豆对氮、磷、钾肥料利用率,本试验通过蚕豆生育期、经济性状、籽粒和茎叶产量、肥料利用率等的调查和分析。结果表明,全肥的情况下,100kg作物对氮、磷、钾的吸收量分别是5.024kg、1.28kg和1.395kg。氮、磷、钾肥的利用率分别为32.28%、10.95%、42.28%。氮磷钾肥的合理施用对蚕豆作物具有显著的增产作用。

In order to explore the utilization rate of nitrogen, phosphorus and potassium fertilizers for broad bean in Huzhu County, this experiment was investigated and analyzed the growth period, economic characters, grain and stem and leaf yield, fertilizer utilization rate of broad bean.The results showed that under the condition of full fertilizer, the absorption of nitrogen, phosphorus and potassium by 100 kg crops were 5.024 kg, 1.28 kg and 1.395 kg, respectively.The utilization rates of nitrogen, phosphorus and potassium fertilizers were 32.28%,10.95% and 42.28%,respectively.The rational application of nitrogen, phosphorus and potassium fertilizers can significantly increase the yield of broad bean crops.
