不同膜色及覆膜方式对旱地马铃薯生长的影响

Effects of Different Film Colors and Mulching Methods on Dry Land Potato Growth

内蒙古自治区是中国马铃薯主产区之一,马铃薯播种面积居全国第一。在内蒙古察哈尔右翼中旗进行不同膜色、覆盖方式对马铃薯产量效应等研究。结果表明,蓄水保墒水能力与覆膜方式有关,与膜色并无相关关系;平抑低温变化方面,黑色膜比白色膜作用强,适应马铃薯栽培;覆膜会有助于马铃薯主茎数和结薯数的增加;覆膜种植能提高马铃薯的产量,全覆黑膜增产效果更加明显。

Inner Mongolia Autonomous Region is one of the main potato production districts in China. Its potato sown area ranks first in China. The purpose of this research was to study how different film colors and mulching methods affected the yield of potato in Chahar Right Middle Banner, Inner Mongolia. Moisture storage capacity was associated with plastic mulching methods, but not with film color. In terms of stabilizing low temperature, the black film was more effective than the white film, therefore, more suitable for potato cultivation. Furthermore, mulching contributed to increase in the number of potato main stem and potato tuber and the yield of potato. Complete coverage of black film was more effective for yield increase.
