【摘要】 通过马铃薯不同栽培方式试验研究,选择适宜天水市山旱地马铃薯主栽品种天薯10号获得高产的有效配套栽培技术模式。结果表明:马铃薯不同地膜覆盖相比对照能提早出苗、成熟,表现出较好的抗旱保墒性和增产效应,增产率60.0%～96.7%。黑膜半膜覆盖栽培下的产量最高,为22 969 kg/hm2,比露地栽培增产11 297 kg/hm2,增产率为96.7%;商品薯率、株高、单株薯重、纯收入最高,生育期最长,病害较轻。更多还原

【Abstract】 Based on the experiment for different potato cultivation patterns,high yield related cultivation techniques and measures were formulated for cv.Tianshu 10,a main potato cultivar suitable for planting in mountains and dry lands in Tianshui.The result showed that emergence and maturity using plastic film mulching technique were faster than the control.By plastic film mulching technique,higher drought resistance and production were achieved,with a yield increase rate of 60.0%-96.7%.Half covering with black membrane had the best performance with a yield of 22 969 kg/ha,better than the open field cultivation.The yield was increased by 11 297 kg/ha,with a increase rate of 96.7%.Half covering with black membrane had the highest marketable tuber rate,plant height,and tuber yield per plant and profit.It aslo could extend the growth duration and reduce disease incidence.更多还原
