摘要
以化香、湖南山核桃、枫杨为砧木及湖南山核桃、浙江山核桃、美国山核桃为接穗,进行嫁接育苗和造林试验,结果表明:化香砧木嫁接育苗成活率最高,达90%以上,且生长快、成本低;化香砧木嫁接的山核桃苗造林后,其抗淹、耐寒及抗虫性较好,且生长快、挂果早,坚果经济性状较稳定。其中以化香砧木嫁接的浙江山核桃果重、出果率、坚果大小,仁色、味道等方面达到或超过了产区标准,出仁率、壳厚接近产区标准。
Taken Platycarya strobilacea, Carya hunanensis, Pterocarya stenoptera as the rootstock and taken Carya hunanensis, Carya of Zhejiang, Carya illinoensis as the scion, the effect of grafting on seedling-raising and planting were studied. The results showed that, when Platycarya strobilacea was used as the rootstock, the grafted seedlings survival rate was the highest which reached 90% or more, and the characteristics of better waterlogging resistance, better cold resistance, better insect resistance, fast growing, early fruiting and fruit feature stability were demonstrated after planting. The fruit weight, fruit production rate, fruit size, nut color and flavor of Zhejiang Carya which was grafted on Platycarya strobilacea met or exceeded the production region standard, the nut rate and shell thickness approached the production region standard.
