1板栗“空蓬”的形成原因1.1品种由于板栗分布地域辽阔,生态条件差异很大,品种良莠不齐。有些地区的群众仍沿用实生繁殖,造成变异大、结果晚、产量不稳定,单株间差异显著。即便有嫁接的,也是随意采条,良种观念淡薄,管理粗放,不能合理配置授粉树,致使单株表现空蓬严重,品质差,产量低,不能给农户带来良好的经济收益。2007年有些短枝类型品种空蓬率高一些。
1 chestnut “empty Peng ” the formation of reasons 1.1 varieties chestnut distribution as a vast territory, ecological conditions vary greatly, the variety of good and bad. In some areas, the masses still use real-life reproduction, resulting in large variation, late results, unstable output and significant differences among single plants. Even if there is graft, but also arbitrarily mining, weak breeding concept, extensive management, can not be properly configured pollination tree, resulting in a serious performance of empty pods, poor quality, low yield, can not bring good economic returns to farmers. In 2007 some spruce types of empty Penglai rate higher.
