宁南山区马铃薯种薯不同栽培模式品种适应性研究

Selection of Cultivation Pattern and Variety for Southern Mountainous Part of Ningxia

本试验针对宁夏南部山区西吉县黄土丘陵缓坡地旱作农业的特殊条件,开展了旱地马铃薯品种不同栽培模式品种适应性研究,试验以不同覆膜方式、不同品种为研究对象,分析其土壤含水量、产量和产值的变化特点。结果表明,宁夏南部山区马铃薯生产适宜选用全膜覆盖栽培模式,从产量和产值考虑,以全膜ב冀张薯8号’为主,全膜ב青薯9号’或半膜ב青薯9号’次之。

A research about cultivation pattern and variety selection was carried out in the loess land of Xiji County in the southern mountainous part of Ningxia.Various mulching models combined with various potato varieties were tested for its soil water content,yield,and value.The experimental data indicated that the whole film coverage was suitable for potato production in the southern mountainous area of Ningxia.When considered from both points of yield and value,the whole film coverage combined with the variety ＇Jizhangshu 8＇ performed best,followed by the whole film coverage combined with the variety ＇Qingshu 9＇ or half film coverage combined with ＇Qingshu 9＇.
