昆明地区板栗提质增效技术措施研究

Technical Measures of Quality and Efficiency Improvement of Castanea mollissima in Kunming

为了提升昆明地区板栗产量和质量,就不同提质增效措施对板栗丰产的重要程度进行了研究。结果认为,不同提质增效措施对板栗丰产的重要程度排序为整形修剪>病虫害防治>土肥水管理。在昆明市宜良县20 hm^2实验地上通过实施2年多的整形修剪、土肥水管理、病虫害防治、品种改良等提质增效技术措施,使板栗平均产量提高到4718.32 kg/hm^2,是改造前的1.59倍,丰产增收效果明显。

In order to improve the yield and quality of Castanea mollissima in Kunming,this paper studied the importance of different quality-enhancing measures.The results showed that the importance order of different measures for improving quality and efficiency was plastic pruning>pest control>soil,fertilizer and water management.Through more than two years of plastic pruning,soil and fertilizer management,pest control,variety improvement and other technical measures to improve quality and efficiency in research area of 20 hm^2,the average yield of Castanea mollissima was increased to 4718.32 kg/hm^2,1.59 times of that before the transformation,and the effect of high yield was obvious.
