摘要
在山坡地条件下，对兰州百合进行了等高垄作及渗水地膜覆盖栽培技术试验。结果表明，与传统平作技术比较，垄作渗水地膜覆盖使百合商品鳞茎产量增加了21．2％；垄作渗水地膜覆盖时，百合植株的田间高度、茎粗和总叶面积分别增加20．87％，10．99％和25．51％，0～30cm根系鲜重增加了45．12％，百合出苗期至显蕾期地温提高了0．9～2．1℃，耕层土壤含水量增加了1．54～2．94个百分点，地表土壤含水量波动明显弱化。
A sloping field experiment was carried out to investigate the effect of contour planting and plastic film mulching on yield of Liliurn＇ dnvidii vat. unicolor and dynamics of soil temperature and moisture. The main points as flowing： the contour planting with permeable plastic film mulching increased the bulb yield of Lilium dnvidii vat. unicolor by 21.2 % compared to the treatment of flat planting without mulching, the plant height, diameter of stem and leaf area was increased by 20. 87 %, 10. 99 % an 25.51 % respectively, the fresh root weight in the soil layer was increased by 45.12%, in the growth stage of seedling and bud display stage, the soil temperature was enhanced by 0. 9-2. 1℃ in 0-25 cm, and the soil moisture was increased by 1.54%-2.94% in 0-30cm, the fluctuate of soil moisture in surface layer was weakened significantly.
