摘要
以云南省林业科学院引进的云栗15、云栗22、云栗44及昭通大板栗等优良品种为试验材料,采用随机区组设计进行板栗早实丰产试验。探讨了板栗园的整地和建植方式、授粉树种的合理配置、整形修剪、适时摘心等种植技术措施以及优良种与合理密植对早实丰产的影响。进一步阐述适时适当合理施肥、林地水肥管理、管抚、林农间种、环割和倒贴皮以及病虫害防治等板栗田间管理措施。
The fine variety of Castanea mollissima 15, Castanea mollissima 22, Castanea mollissima 44 and Zhaotong large chestnut introduced from yunnan Academy of Forestry were took as test materia, Cas- tanea mollissima early fruit and high yield trials was conducted with randomized block design.
