枣庄地区是山东省主要的马铃薯生产基地,自1982年以来,由于推广利用了脱毒种薯及阳畦保种留种技术,产量显著提高。近年来,尽管选用了一些高产品种和改进了栽培技术,但增产幅度不大,春播马铃薯亩产量基本上维持在1500公斤的水平,为进一步提高春播马铃薯的产量,我们进行了马铃薯不同播期的试验(常规春薯于惊垫前后),结果表明:春马铃薯播期越早、产量越高,尤其在大雪前后增产幅度最大,可提高产量50%以上,大薯率可占47%,中薯率可达36%,而春分以后播种则表现减产。因此,春薯改春播为冬播,提早播种(尤其在大雪前后)是提高春薯产量的有效措施。冬播马铃薯栽培技术要点:
Zaozhuang is the main potato production base in Shandong Province. Since 1982, due to popularization and utilization of virus-free seed and Yangba seed-keeping techniques, the output has been significantly increased. In recent years, despite the selection of a number of high-yielding varieties and improved cultivation techniques, but the rate of increase is not large, the yield per acre spring potato basically maintained at the level of 1500 kg, in order to further improve the yield of spring sowing potatoes, we conducted a different sowing date The results showed that: the sooner the spring potato sowing date, the higher the yield, especially in the snow before and after the largest yield increase can increase the yield of more than 50%, the potato yield can account for 47%, potato The rate of up to 36%, while the sowing performance after the vernal cut. Therefore, the spring sowing to winter sowing broadcast, early sowing (especially before and after heavy snowfall) is an effective measure to improve the yield of sweet potato. Winter planting potato cultivation techniques:
