山楂种壳坚硬并长期休眠,过去用人工催芽需要两冬一夏或一夏(秋)一冬的贮藏才能生芽,大大影响了繁殖速度。去年冬季,本社从山西省进了一部分山楂种果,我们运用冬季快速催芽技术进行催芽,结果有1600斤种果催芽成功,到三月萌芽,今春育出山楂苗十四万棵。按含仁种计算发芽率最高的达到百分之七十。主要方法是: 一、反复浸晒,开裂种壳。这是催芽的第一个关键。开裂种壳的办法就是夜间浸泡在水里,白天摊在阳光下晒,反复多次。浸晒的次数根据气温高低而定,一般十一月份需五至十次,十二月份需十至十五次,直至种壳彻底裂开为止。所谓彻底开裂 Hawthorn hard shell and long-term dormancy, the past use of artificial germination requires two winter a summer or a summer (autumn) a winter storage to bud, greatly affected the breeding speed. Last winter, our company got some hawthorn seeds and fruits from Shanxi Province. Using the rapid germination technique in winter, we sprouted a catty of 1,600 pounds of seeds and germinated in March. One hundred and forty thousand hawthorn seedlings were raised in spring. According to the kernel germination rate of 70%. The main method is: First, repeated immersion, cracking shell. This is the first key to germination. Crack shell approach is to soak in the water at night, during the day stalls in the sun drying, repeated many times. The number of immersion drying depends on the temperature. Generally, it takes five to ten times in November and ten to fifteen times in December until it is completely cracked. The so-called complete cracking
