一、砧木选择与处理 对结果晚、产量低、树势较旺的中、幼树,进行单头或多头高接,接口粗度一般为5cm。 二、接穗的选择与贮存 秋季落叶后或板栗发芽前20~30天,自优树上选取发育充实、芽饱满无病虫害的枝条作接穗,采后捆好混入湿锯末,用塑料薄膜袋装好,放在3~5℃的冷库中贮存,亦可在地窖或排水良好的阴凉处挖沟用湿沙埋藏(温度10℃
First, the rootstock selection and treatment of the results of late, low yield, tree vigor is more prosperous, young trees, single or multi-head high access, the interface roughness is generally 5cm. Second, the selection and storage of scion After the fall of autumn or chestnut 20 to 30 days before germination, selection of self-development of trees full growth, bud full of disease-free pests scion, after the harvest bundle mixed wet sawdust, with plastic film bag well , Stored in cold storage of 3 ~ 5 ℃, can also be buried in the cellar or well drenched ditch with wet sand (temperature 10 ℃
