摘要
采用嫁接换种、施肥措施对油茶低产林进行改造。试验表明，低产油茶嫁接换种后，头３年平均鲜果产量可达１６９２．３ｋｇ／ｈｍ２·ａ，比对照增产８１．４０％～１３２．８％，而且产量稳定，逐年上升；施用尿素、猪栏肥、钙镁磷肥的３年平均产量比对照分别增产９８．８０％、６５．７０％和５５．４７％。试验认为，嫁接换种、增加施肥投入及松土除草等技术措施是提高油茶产量的有效途径。
Experiment on transformation of low-yield Oiltea camellia forest with grafting and fertilization demonstrated that after grafting,mean fresh fruit yield of the first 3 years reached 1 692.3kg/hmg2·ah,which increased by 81.40%～132.68% than the control.And tne yield remained stable and increase.Mean yield of treated forest with urea,hog manure and serpentine-fused phosphate increased respectively by 98.80%,65. 70% and 55.47% than the control in the first 3 years.
