研究了无病毒矮化苹果和病毒感染苹果生长及结果的差异。通过无病毒矮化苹果在矮化中间砧全埋土、“刻剥拉”早果丰产及 15主枝细长纺锤形整形修剪等技术的研究创新 ,使无病毒矮化苹果在我国西北黄土高原地区首次大面积示范成功 ,示范推广 10 0 0 hm2 ,实现 6年生无病毒矮化红富士产量 45 t/ hm2。研究还总结了 12 ,15 ,2 0主枝的细长纺锤形树体结构等一系列量化指标 ,为同类地区推广提供了依据
Differences in growth and outcome of apple-infected and virus-infected apples were investigated. By virus-free dwarf apple dwarfing in the middle of anvil buried, “scrape” early fruit yield and 15 main branch elongated spindle pruning and other technology research and innovation, so that non-virus dwarf apple in Northwest China Loess Plateau The first large-area demonstration in the region was successful, demonstrating and promoting 10 000 hm2, achieving a yield of 45 t / hm2 for 6-year-old virus-free dwarfed Red Fuji. The study also summarized a series of quantitative indexes such as the slender spindle-shaped tree structure of 12, 15 and 20 main branches, which provided the basis for the popularization of similar areas
