摘要
[目的]探讨大樱桃高光效树形培养及应用效果。[方法]针对大樱桃郁闭园，对大樱桃树进行去头、去大枝、回缩复壮和花期复剪等，研究修剪措施对大樱桃树花芽、品质、产量及效益的影响。[结果]改造后大樱桃树的花芽数量和果实质量、产量和效益均有明显提高，与对照相比，其花束状果枝和短果枝分别增加了40．2％、41．7％，花芽量增加了51．9％；改造后的1级果率高达85．1％，单果重最高为11．4 g，可溶性固形物平均含量为17．9％，达到良好的口感指标；产量最高达16725 kg／hm2，超出对照221925元／hm2，增加效益1倍多。[结论]该研究可为大樱桃高产栽培提供理论支持。
Abstract
Objective] To discuss the application effects and tree cultivation of high photosynthetic efficiency of Cerasus pseudocerasus.[Meth-od] As for cherry canopy park, the decaptitating, removing big branches, retraction rejuvenation, and complex shear pruning at flowering period were carried out for C.pseudocerasus.We researched the effects of pruning treatment on flower bud number, yield and benefit of C.pseudocera-sus.[Result] The flower bud quantity, fruit quality, yield and benefit significantly enhanced in modified C.pseudocerasus.Compared with the control, bouquet spur and short branch increased by 40.2%and 41.7%, respectively.Flower bud number enhanced by 51.9%. The first-grade fruit rate reached as high as 85.1% after modification.The greatest weight of single fruit was 11.4 g; the average content of soluble solid was 17.9%, reaching good taste index.The highest yield was 16 725 kg/hm2 , which was 221 925 yuan/hm2 higher than the control, and was more than double of the original benefits.[Conclusion] This research provides theoretical support for the high-yield cultivation of C.pseudocerasus.
