山楂按常规育苗方法从采种至嫁接成苗,一般需要4—5年。缩短山楂苗的培育年限、提供培育足够的优质苗木的方法,是发展山楂生产的一个重要环节。我们进行了为期三年的山楂种子快速育苗试验,取得了一定的进展。据1988年秋季调查当年生苗平均高达0.83米,最高可达1.07米,平均地径可为0.7米。其方法主要是用浓硫酸浸蚀种子。具体作法如下。在11月上、中旬,将当地成熟的桔红山楂种子,在气温10—15℃条件下,以相当于种子重量一年的浓硫酸浸泡种子12—13分钟(及时搅拌)。再用清水冲洗揉搓去掉碳化层后浸
Hawthorn seedlings by conventional methods from seed to graft seedlings, the general need 4-5 years. Hawthorn seedlings to shorten the incubation period, to provide sufficient nurturing high quality seedlings is the development of hawthorn production is an important part. We conducted a three-year rapid seedling experiment of hawthorn seeds and made some progress. According to the survey in autumn 1988, the average annual seedlings were as high as 0.83 meters and the highest was 1.07 meters with an average diameter of 0.7 meters. The main method is to use concentrated sulfuric acid etching seeds. Specific practices are as follows. In mid-November, locally ripe orange hawthorn seeds are soaked in concentrated sulfuric acid equivalent to one-year seed weight for 12-13 minutes (with immediate stirring) at a temperature of 10-15 ° C. Rinse with water and then remove the carbide layer after dip
