在南疆平原地区,马铃薯单季作就地留种1—2年后,很快发生退化,植株畸形弱小,病毒严重,薯块变小,产量大降。从山区引种,不仅耗费巨大,而且远不能满足生产需要。因此,南疆马铃薯栽培面积逐渐缩小,市场供应紧张。为探索克服马铃薯退化的途径,我们从1974年起,先后从牌楼农场和其它单位引进生育期短、丰产、抗退化的品种,进行两季栽培,基本上控制了退化现象,春、秋两季亩产均在2,500斤左右,高产田可达4,200斤。目前我团种植的马铃薯已全部实行两季作,其主要
In the southern plain of Xinjiang, potatoes were planted for one to two years in a single season and then quickly degenerated. The plant deformity was weak, the virus was serious, the tubers became smaller and the yield dropped greatly. Introduced from the mountains, not only costly, and far from meeting production needs. Therefore, the southern area of ?? potato cultivation gradually reduced market supply. In order to explore ways to overcome the degradation of potato, we started from the archway farms and other units to introduce short-lived, high-yielding and anti-degraded varieties from 1974 onwards for two-season cultivation and basically controlled the degradation. Spring and autumn Yields are about 2,500 pounds per mu, high-yield fields up to 4,200 pounds. At present, the potato planted in our regiment has all been implemented in two seasons, its main
