【摘要】 通过品种、扦插密度、收获时间3因素4水平正交试验,对单盘产量、粒数及商品粒(≥1g/粒)数进行直观分析和变量分析,从试验结果综合来看,中早熟品种、插植70穴/盘、70 d 左右收获,单盘粒数和商品粒最多,产量较高。更多还原

【Abstract】 The yield per plate,minituber number and the number of minituber more than 1 g were investigated using a orthogonal design including 3 factors and 4 levels of each factor.The re- sults shown that early and medium maturing varieties,planted at the density of 70 plants per plate and harvested about 70 days after planting,could get higher number of minituber per plate,higher number of minituber more than 1 g and higher yield than other treatments更多还原
