新疆纤用亚麻高产栽培模式研究

目的]通过亚麻栽培试验,筛选适合新疆亚麻生产种植的最佳栽培措施.方法]采用不同留苗密度、施肥和灌溉的三因素正交栽培试验.结果]影响原茎产量高低的栽培因素为施肥>灌溉>留苗密度,影响种籽产量高低的栽培因素为灌溉>留苗密度>施肥.结论]在新疆亚麻主产区以每667 m2留苗160×104株、施肥20㎏和灌水160 m3(2次)为获得亚麻原茎产量的最佳组合;以每667 m2留苗80×104株、施肥20 kg和灌水80 m3(1次)为获得亚麻种籽产量的最佳组合.

Studies on High-yielding Cultivation Model of Xinjiang Flax

Objective]The optimum cultivating method for flax production were screened by flax cultivation experiment in Xinjiang.Method]Orthogonal test was caried out with three factors:different density,fertilizer and irrigation quantities.Result]The factors affecting the stem yield are fertilizer,irrigation and density,the factors affecting seed yield are irrigation,density and fertilizer.Conclusion]An optimized model in cauline yield for Xinjiang is density 1.6million plant/667 m2,fertilizer application of 20.0kg/667 m2,irrigateion 160 m3/667 m2(twice) and in seed yield density is 0.8million plant /667 m2,fertilizer application of 20.0 kg/667 m2,irrigation 80 m3/667 m2(one time).
