半干旱地区马铃薯不同黑膜覆盖栽培方式比较

Comparison of Black Plastic Film Mulching for Potato Planted in Semi-arid Region

马铃薯已成为干旱半干旱地区的主栽作物之一,为了筛选出最佳种植模式,针对本地生产上使用范围较广的5种马铃薯不同黑膜覆盖栽培模式与露地种植进行了对比试验。通过田间观察、综合性状和实际测产等方面比较,结果表明,马铃薯黑膜全覆盖双垄侧播栽培模式综合性状优良,产量表现最佳,为26.72 t/hm2,比对照露地垄作和露地平作分别增产43.99%和54.21%。该覆膜方式经济效益显著,技术简单易行,适宜在定西市半干旱地区进行大面积推广。

Potato is one of the main crops grown in arid and semi-arid regions. In this research, five black plastic film mulching methods and open field cultivations were compared in order to identify the optimal cultivation mode. Based on comparisons of field survey data, comprehensive traits and yield, it was found that double ridge black film mulching and side seeding cultivation mode gave the best results, yielding 26.72 t/ha, 43.99% and 54.21% higher than that of open ridge cultivation and open flat cultivation, respectively. This mulching mode is economic, easy operation, and suitable to be extended in large scale in the semi-arid region of Dingxi City.
