摘要
为了探索在岗丘瘠薄地高效栽培黄金梨的技术,以河南省南阳市东大岗为例,进行了为期5年的无公害黄金梨优质生产试验。结果表明,黄金梨适宜在岗丘瘠薄地大力推广,早期最适宜的栽植密度为2m×3m,树形宜采用基部三主枝疏层分散型。要严格掌握黄金梨套袋时机,严格控制单株留果量,适时采收果实。
In order to realize the highly effective cultivation of Golden Pear at barren hillock areas, the pollution-free cultivation test lasting 5 years were carried out at Dongdagang of Nanyang. The results showed that Golden Pear was suitable to extension at barren hillock areas. The most suitable planting density was 2 m×3 m at early stage, and the most suitable tree shape was low trunk and three main branches with loose and dispersed layer. The right chance of fruit bagging must be seize, allowance for fruit setting must be controlled, and fruit must be timely harvested.
