板栗野生砧木嫁接建园丰产技术研究

在大别山区北坡利用板栗野生砧木嫁接建园，引进省内主产区的11个品种和当地主栽的2个品种进行品比试验。施行的插皮舌接、夏季摘心、改土增肥、综合措施防治剪枝象甲等系列丰产配套技术均显成效，嫁接5年后便进入丰产期，6～10年生年株产达2．4okg,单产1500Kg／hm2，其中二新早等7个品种平均株产达3．3kg，单产2000kg／hm2，达到了丰产指标，为野生板栗资源的合理开发利用开辟了途径。

Studies on Techniques for High Yield of Castanea mollissima Orchard Constructed by Grafting with Wild Stocks

The orchard of Castanea mollissima was constructed by grafting with wild stocks in the northern slope of Dabie mountain and 11 varieties were introduced from the main yielding areas to compare with 2 lcoal varieties. A series of applied techniques, such as whip grafting, removing cores, replacing soil and fertilization and integrated control of Cyllorhynchite stisulus had evident effects of increasing yield of Castanea mollissima. which opened up an approach to rational development of resources of wild Castanea mollissima orchard.
