一、引言马铃薯的休眠期是一种良好的生物学特性,是适应外界环境条件而进化的结果。马铃薯休眠期的长短因品种,贮藏条件的不同而异。休眠期一般在2—3个月的范围之内,但有的品种休眠期极短,而某些野生种则几乎没有休眠期。马铃薯休眠期也是生产实践上一种有利的特性,谁都知道休眠期中的马铃薯塊茎极容易貯藏。然而,生产实践上的具体要求往往是不同的,所以又常常需要调节马铃薯的休眠期。例如:二季栽培时,应该消除春播夏收塊茎的休眠期以促其迅速萌芽;而夏播时,又必须延长马铃薯塊茎的休眠期使在翌年夏播之前不至於萌芽过早。
I. INTRODUCTION Potato dormant period is a good biological characteristics, is to adapt to the external environmental conditions and the evolution of the result. The length of potato dormancy varies by variety and storage conditions. The dormancy period is generally within the range of 2-3 months, but some varieties have extremely short dormancy periods, while some wild species have almost no dormancy period. Potato dormancy is also an advantageous feature of production practice, and everyone knows that dormant potato tubers are extremely easy to store. However, the specific requirements of production practice are often different, so often need to regulate the dormancy of the potato. For example, in the second season cultivation, the dormancy of the tubers should be eliminated during the spring seeding to promote its rapid germination. In summer seeding, the dormant period of the potato tubers must be prolonged so that it will not germinate before the next summer sowing.
