| Abstract: |
| 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. |
