一、马铃薯地膜覆盖栽培。覆盖地膜后,不仅可使土壤垄面保持湿润,节约用水,同时还可提高土壤温度,促进马铃薯生长发育。据试验,覆盖地膜栽培的马铃薯块茎膨大早、生长快,不仅可以缩短生育期,提早上市,而且还可提高薯块的商品率。具体做法:采取宽垄双行栽培,垄宽1．5 First, the potato mulching cultivation. Covering the plastic film, not only can keep the soil ridge moist, water conservation, but also improve the soil temperature and promote potato growth and development. According to the experiment, potato tubers covered with plastic film grow early and grow fast, not only can shorten the growth period and get to market earlier, but also increase the commodity rate of potato pieces. Specific approach: to take wide ridge double-line cultivation, ridge width 1.5
