马铃薯冬种多种种植方式对比试验结果表明:稻草覆盖免耕大畦种植方式,综合性状好,产量高,增产效果显著,最适宜本地推广;稻草覆盖免耕小畦种植方式,综合性状表现较差,产量低,不适宜推广;普通地膜(白色)和黑膜覆盖翻耕小畦种植二种种植方式,出苗快,出苗率高,产量较高,但生长后劲不足,且薯体商品性差,可以选择性推广;普通地膜和黑膜+稻草覆盖免耕小畦种植二种种植方式,出苗慢,出苗率低,产量较低,且经济性状表现差,不适宜本地推广。
The comparison experiments are carried out among winter potatoes with various planting patterns. The results show that the straw covering no-tillage big bed planting pattern provides good comprehensive characters, high yield and obvious yield increasing effect, which is suitable to be popularized in this area; for the straw covering no-tillage small bed planting pattern, it has relatively worse comprehensive characters, low yield and is not suitable for popularization; for ordinary film (white) and black film covering tillage small bed twice planted planting pattern, it has the advantages of quick emergence, high emergence rate and high yield, however, the crops don't grow well then and the potatoes lack commercial quality, so it can be popularized selectively; for ordinary film and black film + straw covering no-tillage small bed twice planted planting pattern, it results in slow emergence, low emergence rate and low yield and bad economic performance, so it is not suitable for popularization in this area.
