为提高核桃嫁接成活率,缩短育苗周期,加快木本油料树种的发展,我们于1978年12月,在山东农学院进行了核桃子苗嫁接试验。试验初获成果后,又在河南省洛宁县长水大队进行了塑料温棚和田间试验。通过一年来连续试验所得结果,我们认为这种方法是行之有效的,较苗砧嫁接缩短育苗期一年。一、子苗砧的培养用当地核桃做砧木。播种前,将核桃用温水浸种5—8天(视壳厚薄而异),每天换水1次,当部分核桃裂口后进行播种。在温棚内培养砧苗(1979年1月下旬至3月20日)或在田间(3月下旬)培育砧苗(时间视当地气候条件而定)。核桃播于以蛭石做
In order to improve the survival rate of walnut grafting, shorten the seedling cycle and speed up the development of woody oilseed species, we conducted the grafting experiment of walnut seedlings in Shandong Agricultural College in December 1978. After the test results were first obtained, and in Longning County, Henan Province, Changshui Brigade conducted a plastic greenhouse and field experiments. Through a year of continuous test results, we believe that this method is effective, compared with the seedling grafting shorten the breeding period of one year. First, seedling anvil cultivation with local walnut rootstocks. Before sowing, the walnut soak with warm water 5-8 days (depending on the thickness of the shell), change the water 1 times a day, when part of walnut sowing after sowing. Anvil seedlings are grown in a greenhouse (late January to March 20, 1979) or in the field (late March) (time depends on local climatic conditions). Walnut broadcast on vermiculite
