山丁子是嫁接苹果和香槟,秋果的优良砧木,为加速经济林苗木的繁育速度,我圃科研组进行了山丁子双膜覆盖集约育苗,取得了显著的效果,现将育苗技术总结如下: 育苗地位于本圃西部的原果树地。由于多年不予耕作,土壤瘠薄,30—40厘米以下都是河卵石;圃地海拔高,气候条件差,如果不采用新的技术手段,想提前出苗,提高苗木的数量和质量是难以办到的,针对这一情况,我们采用如下的技术措施:
Hill Dingzi grafted apples and champagne, autumn fruit good rootstocks, in order to speed up the economic seedlings breeding speed, I nursery scientific research groups were double-membrane Hill seedlings intensive intensive nursery, and achieved remarkable results, the nursery techniques are summarized as follows: Nursery It is located in the original fruit tree in the western part of this garden. Because many years do not tillage, soil is infertile, 30-40 centimeters below the river pebbles; nursery high altitude, poor weather conditions, if you do not use new technology, want to emerge in advance to improve the quantity and quality of seedlings is difficult to do In view of this situation, we adopt the following technical measures:
