摘要
针对高寒半干旱地区降水少、蒸发量大和养分低的状况,进行了马铃薯覆膜集肥试验。试验结果表明,覆膜集肥可明显加大土壤养分消耗和活化,在马铃薯生育前期和后期可提高土壤温度,在降水少时表现较好的保墒效果,从而显著地提高马铃薯产量。
With the shortage of rain,large evaporation and low level of soil nutrient in the cold and semi-arid areas of high plateau, the experiment with plastic film covering and fertilizing on potato field was conducted. The result showed that: Plastic film covering and fertilization obviously increased the expenditure and effectiveness of soil nutrient, improved the soil temperature during the former and later living period and had a good sustaining water effect when it was short of rain. Because of all factors above mentioned, the yield of potato was improved significantly.
