不同覆膜栽培对冬作马铃薯的影响

Study on Cold and Drought Resisting Cultural Methods for Early- maturing Potato(Solanum tuberosum L.) in Guizhou

为指导贵州冬作马铃薯合理防寒、抗旱,以早熟品种"中薯3号"为材料,研究不同覆膜栽培方式对冬作马铃薯的影响。结果表明:起垄后覆膜的栽培方式影响出苗时间,但不影响出苗率;起垄后覆黑膜栽培方式增产效果最显著,商品薯率最高,产值为2 759.6元/667 m2,纯收入为992.1元/667 m2,比对照增收538元,增收118.5%。说明起垄后覆黑膜可作为一种有效的防寒抗旱栽培方式在冬作马铃薯中进行适当面积验证及推广应用。

The effects of different types of cultural methods on winter potato were studied to obtain detailed data to help farmers on cold and drought resisting work by using ＂Z^hongshu3＂ variety. The results showed that covered plastic method can led to earlier seedling emerge time with close emergence rate. Comparing with control and others methods, covered black plastic method had made a significant potato yield and tradable potato rate. And this method can produce 2 759.6 yuan output , 992.1 yuan net income ,and 538 yuan and 118. % income increase per 667 m2, and could be recommended to use as trial for effective cold and drought resisting method in winter potato in Guizhou.
