马铃薯稻草覆盖免耕栽培与传统栽培比较研究

Comparative Studies on Straw-covered No-tillage Cultivation with the Traditional Cultivation in Potato

为探索马铃薯稻草免耕栽培增产机理,我们开展了马铃薯稻草覆盖免耕栽培与传统栽培比较研究。结果表明,与传统栽培相比,稻草覆盖免耕栽培马铃薯薯皮光滑,块茎大小整齐,出苗率高,株高和叶片数较多,中、后期植株生长速度明显加快。分枝数多、单株块茎重和大薯率高是马铃薯稻草覆盖免耕栽培增产的主要原因。

A comparative study between straw-covered no-tillage cultivation and the traditional cultivation was conducted in order to understand the mechanism of yield increase in potato straw-covered no-tillage cultivation. Compared with traditional cultivation, potato in straw-covered no-tillage cultivation had smooth skin, uniform tuber size, high emergence rate, and more plant height and leaves, and plant growth rate had been accelerated noticeably in the middle and late stage. More main stem number, higher tuber set per plant and higher marketable tuber percentage were the main reasons for yield increase in straw-covered no-tillage cultivation of potato.
