过去板栗多采用实生繁殖,结果较晚,七、八年甚至十几年才结果,并且产量低,品质差,变异性大。现在都通过嫁接良种,第二年就结果,四、五年株产就能达到10—15斤。可是,目前由于对嫁接技术没有很好掌握,对影响嫁接成活的因子还不了解,造成嫁接成活率不高。因此,有必要对这方面的经验加以总结分析,以资借鉴。现根据调查材料谈谈个人意见,供参考。
The past, the use of real chestnut multiplication, the results later, seven or eight years or even ten years before the result, and low yield, poor quality, large variability. Now through grafting elite, the second year results, four or five years will reach 10-15 kg strain production. However, due to the grafting technology is not well understood, the factors that affect the survival of graft do not understand, resulting in graft survival rate is not high. Therefore, it is necessary to sum up the experience in this area for reference. Now based on the survey material to talk about personal opinion for reference.
