摘要
以‘费乌瑞它’马铃薯为试验材料,在冬闲稻田进行地膜覆盖、小拱棚覆盖、双膜覆盖(膜覆盖+小拱棚覆盖)和裸地等栽培田间比较试验。结果表明:双膜覆盖的增温效果最好,出苗期内其平均土壤温度分别比小拱棚覆盖、地膜覆盖和裸地栽培高0.33、1.93、2.89℃;双膜覆盖栽培的马铃薯出苗最早,分别比小拱棚覆盖、地膜覆盖、裸地栽培的提早4、21、31 d;覆膜处理的马铃薯植株株高均显著高于裸地栽培,但茎粗和主茎数均显著低于裸地栽培;双膜覆盖栽培马铃薯的总产量和商品薯产量最高,分别为31.18、28.54t/hm2,小拱棚覆盖和地膜覆盖栽培次之,覆盖处理的总产量和商品薯产量均显著高于裸地栽培;双膜覆盖栽培的效益最好,为1.222万元/hm2。
Favorita, a breed of potato was selected as a test material to compare its growth and yield under four different cultivation circumstances in winter fallow rice fields, they are plastic mulching, arch plastic mulching, plastic mulching plus arch plastic mulching （ also called double films mulching ） and non-mulching. The results showed that the daily average soil temperature with double films mulching was highest, higher than that of plastic mulching, arch plastic mulching and non-mulching 0.33, 1.93, 2.89 ℃, respectively. Therefore, potatoes cultivated with double films mulching was the first one in seedling sprout, which was earlier 4, 21, 31 d than those of cultivated with plastic mulching, arch plastic mulching and non-mulching, respectively. Although the plant height of potatoes cultivated with plastic mulching was higher than that of potatoes cultivated with non-mulching significantly, the stem diameter and main stem number were significantly less than that of potatoes cultivated in non-mulching. Double films mulching cultivation could improve total yield and market needed tuber yield, with 31.18 and 28.54 ton per hectare respectively. And the next were cultivated in arch plastic mulching and plastic mulching cultivation in turn, which were significantly higher than that of potatoes cultivated with non-mulching. The profit of double films mulching cultivation was the highest with 12.22 thousand CNY per hectare.
