| 中文摘要: |
| 研究了陇中半干旱地区垄沟栽培、垄作栽培、平作栽培以及施肥量和种植密度对马铃薯产量的影响。结果表明:垄沟栽培较平作栽培增产72.0%,每hm2纯收入增加1 050元;垄作栽培较平作播种栽培增产36.0%;三元复合肥施用量以675 kg/hm2为宜;种植密度以4.8万株/hm2为宜。 |
| 英文摘要: |
| This paper studied the effects of different cultivation condition on production of potato in semiarid areas of Gansu,such as ridge and furrow sowing, bed-planting in seeding stage,flat planting sowing,as well as fertilizing amount and planting density and so on.The result indicated that ridge and furrow planting can increase the average yield by 72.0%,and increase the pure income by 1 050 yuan/hm2; bed-planting in seeding stage can increase the yield by 36.0% compared to flat planting sowing and cultivation;the suitable fertilizing amount of NPK compound fertilizer is 675 kg/hm2; and the suitable planting density is 4.8×104 plant/hm2. |
