摘要
本试验采用农业部推荐的"3414"试验模型对云南冬季亚麻氮、磷、钾的效应进行了研究。结果表明:施用氮、磷、钾肥均影响亚麻原茎、种子和全麻的产量,其中无氮肥处理较其余处理差异达极显著水平;通过三元二次肥料效应对各处理的配方施肥模型进行拟合,拟合程度良好,模型具有实际价值,可供生产上参考应用。
The field fertilizer tests with ＂3414＂ Model recommended by Ministry of Agriculture were studied by fertilizing Nitrogen, Phosphorus and Potassium in flax fields in winter. The results showed that Nitrogen, Phosphorus and Potassium all had effect on straw, seed and fibre yields of flax. Compared with other treatments, the non -nitrogen treatment was significantly different. Regression models were estab- lished on the basis of the three - factor - quadratic functions, the fitting degrees were good. These models could provide a reference for practical production.
