摘要: 在传统的砂田抗旱保温基础上,为进一步选取较适宜的保水保温方式,提高砂田生产效率,在宁夏中卫干旱山区砂田上进行覆盖地膜、塑料碗和直接在砂田播种西瓜三种不同处理方式进行试验研究。结果表明:在砂田上再次覆盖,对加快西瓜出苗、保苗及后期的生长和提高产量有一定的促进作用;三种处理方式中,覆膜处理保墒效果最好,盖塑料碗处理的保温效果最好;但从经济角度,盖塑料碗处理成本相对较高,而该地区气候特点以干旱为主,因此建议在当地推广覆膜生产方式比较经济实用,在低温年份可适当采用盖塑料碗的方式。

Abstract: Traditional gravel and sand mulched field has a certain capacity of water and heat preservation,in order to choose feasible covering techniques in enhancing the production efficiency on it,the investigation of meteorological effect on three kinds of covering techniques on the gravel and sand mulched field such as coving with plastic film,covering plastic bowl and no covering has been done at the arid mountain area in Zhongwei,Ningxia.The results indicated that coving with plastic film and covering plastic bowl on the gravel and sand mulched field all facilitate to the seedlings' coming out,growth and yield;covering with plastic film had the best capacity on keeping moisture,while covering with plastic bowl had the best capacity on keeping soil temperature.Owing to the local arid climate and take the cost of each covering approaches into consideration,the covering of plastic film on gravel and sand mulched field can be feasible to plant watermelon and the covering of plastic bowl can be used in spring with lower temperature.
