解决良种嫁接是发展板栗的先决条件。为此,江西农业大学园艺系于1992年3月上旬开展了板栗切接试验,结果表明,用2年生砧木就地嫁接的成活率最高为66％:用起出的2年生砧苗室内嫁接,然后再定植的成活率稍低,为56％;用购进的1年生 Solving grafting is a prerequisite for the development of chestnuts. Therefore, the horticultural department of Jiangxi Agricultural University carried out the chestnut jointing test in early March 1992, and the results showed that the highest survival rate of 66% was with 2-year-old rootstock grafting in-place: using 2-year- The survival rate of replanted plants is then slightly lower, at 56%; the one-year births purchased
