青海高原由于海拔高、生长期短,經常因早霜的突然降临使马鈴薯不能及时成熟,而降低产量。青海省许多单位获得馬鈴薯丰产的經驗指出:春化晒种是取得高产多收的一項必要措施。单項試驗的结果也都証明春化处理可以增产14—62%,并且能增强抗旱力,提高出苗率,促进成熟和增加淀粉含量。 春化处理的方法很多,但大部分都采用室外坑
Qinghai Plateau due to high altitude, short growth period, often due to the sudden arrival of early frost so that the potato can not be timely maturation, and reduce production. The experience gained by many units in Qinghai Province on the high yield of potato indicates that vernalization and sunning is a necessary measure to achieve high yield and high yield. The results of individual experiments also prove that vernalization can increase yield by 14-62%, and can increase drought resistance, increase germination rate, promote maturity and increase starch content. There are many ways of vernalization, but most are outdoor pits
