- Abstract:
-
The experiments were designed and implemented to investigate soil water storage under different planting densities, potato(ZHUANG3 type) yield components,yield and water use efficiency under plastic mulch on dry land of south Ningxia. The result showed that mulching could significantly improve soil water storage in the depths of 0—40 cm and 40—100 cm, potato tuber yield(25.2%) and water use efficiency(28.0%). Whether or not the mulch was used, potato production and water use efficiency increased with the increase of the density. The trend followed the density order 6.0×104 plants/hm2 > 7.5×104 plants/hm2 > 4.5×104 plants/hm2. And the indicators of the mulching were better than no mulching. The conclusion of the experiment is that the optimal potato planting practice is mulching and density of 6.0×104 plants/hm2,which can achieve high yield and soil water use efficiency in dry land.
