| 摘 要： | 试验以"西成薯007"原种为材料,采用四元二次正交旋转回归组合设计方法,研究栽培密度和施用氮、磷、钾肥料对"西成薯007"鲜薯和淀粉产量的影响.研究结果表明:各因素对鲜薯和淀粉产量的作用顺序为:密度＞磷肥用量＞氮肥用量＞钾肥用量;在较大密度,较多氮、磷肥的前提下,增施钾肥可获得鲜薯和淀粉的高产;"西成薯007"的鲜薯、淀粉高产综合配套栽培措施:5月下旬至6月上旬栽插密度为3500～4000株/667 m2,667 m2施尿素9～11kg、过磷酸钙10～14 kg、硫酸钾11～14 kg,立冬前后收获,在中等肥力田块种植即可获得鲜薯2000kg/667m2、淀粉500kg/667m2以上的产量.

| Abstract: | In this experiment,taken 'Xichengshu 007' as material,quadratic orthogonal by four yuan rotational regression method was designed to analyze 'Xichengshu 007' fresh yield and starch production affected by planting densities,fertilizer regime of N,P,K.The results showed that factors were as follows: P>N>K;under high planting densities,high N regime and high P regime condition,high fresh yield and starch content were arrived association with the increasing of K regime.The best cultural strategy for 'Xichengshu... |
