天祝县金强河高寒地带马铃薯覆膜试种研究

Jinqiangriver covered potato by plastic experimentally cultivation research in alpine region of Tianzhu County

通过覆膜技术种植马铃薯试验表明,在海拔3000m,年均气温-0.1℃左右的高寒地区试种,覆地膜处理的薯块产量(1234.0g/株)大于不覆地膜(577.2g/株),生长最快时期为8月下旬到9月中旬。覆膜促使土壤温度升高,加快生长,并促进土壤养分转化,对薯块产量有明显的增加作用;覆膜试种成功解决了牧区牧民吃蔬菜难的问题,同时也解决了牛羊冬春季节补饲多汁饲料缺乏的问题。

Indicated through the membrana tectoria technology planter potato experiment that in eleva- tion 3000m, the yearly average temperature -0.1℃ about high and cold area plants experimentally, membrana tectoria 0.005ram leaves processing the potato block yield （1234.0g/plant） to be bigger than CK （577.2g/plant）, production quickest time for late August to mid-September. The membrana tectoria urges the soil temperature to elevate, speeds up the growth, and promotes the soil nutrient to transform, had obviously to the potato block output increases the function, the membrana tectoria plants experi- mentally solves the pastoral area herdsman to eat the vegetables difficult question successfully, and solved the cattle and sheep winter season to make up raises the succulent fodder deficient question.
