“克新一号”马铃薯是黑龙江省克山农科所用“374—128”作母本,“波兰一号”作父本杂交选育而成。我县通过几年来大量引种春植实践证明,该品种具有结薯早、产量高、抗病虫、退化性弱、块茎大等特点,一般亩产1000～1500公斤,高产农户可达2500～3000公斤。其主要栽培技术如下。 一、种薯处理 每年从黑龙江调入“克新一号”马铃薯秋植薯种作春植,因贮藏时间短,没有度过休眠期。因此,播种前必须用人工方法打破休眠期,促使种薯提早发芽,有利早播种。打破休眠的方法是:
“New Zealand grams of” potato is Keshan agricultural use of “374-128” as a female parent, “Poland One” as a parent of cross breeding. In recent years, our county has introduced a large number of spring planting practices to prove that the varieties have the characteristics of early tuber yield, high yield, resistance to pests and diseases, weak degeneracy, large tubers and the like, generally yielding 1000 to 1500 kg per mu and high yielding farmers up to 2500 to 3000 kg. The main cultivation techniques are as follows. First, the seed potato processing transferred from Heilongjiang each year, “New Zealand gram” potato autumn planting potato plants for spring planting, storage time is short, did not spend the dormant period. Therefore, artificial methods must be used before sowing to break the dormancy period, prompting the seed germination earlier, favorable early sowing. The way to break dormancy is:
