【摘要】 采用分三个正交区组的四因素二次正交旋转组合设计方法,研究了乌兰察布地区施用有机肥和氮、磷、钾对马铃薯产量、淀粉含量及商品率的影响。结果表明:氮、磷、钾和有机肥的合理配合施用能使马铃薯产量、淀粉含量和商品率明显提高。最后,通过计算机模拟寻优获得了在本试验地条件下马铃薯高产、优质、高效的配方施肥方案。更多还原

【Abstract】 Field experiment was conducted in Wulanchabu with the design of orthogonal second order rotational regression of four factors in three orthogonal blocks to study the effect of N,P₂O₅,K₂O and organic fertilizer combined application on yield,starch content and marketable tuber rate of potatoes.Results showed that combined application of N,P₂O₅,K₂O and organic fertilizer could increase yield significantly,starch content and marketable tuber rate of potato.Finally,we obtain the optimization scheme of fertilizer use for the potato production by computer simulation in this experiment conditions.更多还原
