摘要
江西省马铃薯种植开始广泛应用冬种稻草覆盖免耕栽培技术,为探索适合该技术种植的马铃薯品种,试验以10个马铃薯品种为材料,采用稻草覆盖免耕栽培方式播种种植,调查各品种的生育期、薯块特性以及产量。结果表明:由于2010年两次低温霜冻天气,各品种出苗率受到不同程度的影响,但均达到了96%以上,而生育期也比正常年份推迟20 d左右。10个品种的薯块性状表现差异不大,综合性状较好的有郑薯5号、郑薯6号和费乌瑞它。产量结果表现较好的有对照品种东农303、郑薯5号和郑薯6号,所以这3个品种更为适合万载县大面积推广种植。
This research aimed at exploring the varieties which could adapt to the non-tillage winter cropping of potato with ricestraw coverage cultivation,a technique which is widely used in potato planting in Jiangxi Province.Ten varieties were planted by non-tillage cultivation in the test.Growth period,tuber characteristic and yield were investigated.The results showed that due to two times of low temperature in 2010,the emergence rate was affected to some extent,but all over 96% and the growth period was also increased by about twenty days.Tuber characteristics of all varieties had little difference.Comprehensive traits of three varieties（Zhengshu 5,Zhengshu 6 and Favorita） were better when compared with others.Zhengshu 5,Zhengshu 6 and Dongnong 303（CK） could be recommended to plant in large scale based on their yield performance.
