摘要
为探究厢面倾斜角度对山药产量和畸形率的影响,以4种山药品种为试验材料,探索不同倾斜角度条件下山药产量和畸形率变化。结果表明,倾斜角度提升至20°左右时,与对照相比,双胞山药、双棒山药、铁棍山药和紫山药的产量分别提高了74.85%、13.59%、10.08%、42.37%,双胞山药、双棒山药和紫山药畸形率分别降低了30%、35%、100%,其中紫山药的畸形率降为0。因此,厢面倾斜角度的适当提升可有效提高浅生槽栽培山药的产量,并降低薯块畸形率。
In order to explore the effects of the tilt angle of the compartment surface on the yield and deformity rate of yam,four yam species were used as experimental materials to explore the changes of yam yield and deformity rate under different inclination angles.The results showed that when the inclination angle was increased to about 20°,the yields of twin yam,double stick yam,iron stick yam and purple yam increased by 74.85%,13.59%,10.08%and 42.37%,respectively,and the deformity rates of twin yam,double stick yam and purple yam were reduced by 30%,35%and 100%,respectively,and the deformity rate of purple yam was reduced to 0.The appropriate increase of the inclination angle of the compartment surface can effectively improve the yield of yam cultivated in shallow troughs and reduce the deformity rate of potato tubers.
