以农林废弃物稻壳、锯木屑、树皮等为主要原料,研究油茶容器育苗的基质配方对油茶嫁接成活率和根系生长的影响。试验结果表明:锯木屑、黄心土有利于油茶苗木根系生长。锯木屑作主配料,黄心土作辅配料;谷壳对油茶苗木根系的生长不利,应控制其比例。基质最佳配方是锯木屑∶树皮为1∶1,或为锯木屑∶黄心土为2∶1。管理措施是:对基质进行堆沤预处理,嫁接愈合后尽量提前栽植,及时盖膜保温,高架托盘进行空气修根,适时施肥。
The main raw materials of husk, sawdust and bark were used to study the effects of matrix formulations of Camellia oleifera seedling on grafting survival rate and root growth of Camellia oleifera. The test results show that sawdust and yellow heart soil are good for root growth of Camellia oleifera seedlings. Sawdust-based ingredients, yellow heart soil for the auxiliary ingredients; chaff on the growth of the root of Camellia oleifera unfavorable, should control the proportion. The best matrix recipe is sawdust: bark 1: 1, or sawdust: yellow heart soil 2: 1. Management measures are: pretreatment of the reactor pile heap, graft as far as possible after planting in advance, cover the membrane insulation, elevated tray for air root repair, timely fertilization.
