Abstract Using ?Dongkui?bayberry cultivar as test plant , the effects of different antifreeze patterns on grain yield and fruit quality of bayberry grown in mountainous areas were studied in the field experiments during ２００８ and ２０１０ . Results showed that , compared with the control , the antifreeze patterns significantly reduced the decline rate of the nitrogen , phosphorus and potassium contents of bayberry leaves in winter , and the effect of the greenhouse pattern was the best , whose decline rate was １１.０％ ,２０.３％ , １６.５％ , respectively , and the water content of bayberry leaves under greenhouse pattern remained stable in the winter period . The antifreeze patterns could promote the growth of spring shoots and increased their nitrogen contents .Compared with the control , the increasing rate of nitrogen contentof spring shoots under greenhouse pattern was the biggest , increasing by １４ .６％ . The antifreeze patterns significantly increased the nitrogen , phosphorus and potassium contents of fruits , especially the greenhouse pattern being the best . Compared with the traditional antifreeze patterns , the greenhouse pattern significantly improved mass , soluble solid , sugar and vitamin C contents of the bayberry fruit , and reduced the acidity of fruit , and then improved fruit quality of bayberry . The yield of bayberry under
greenhouse pattern was the greatest and increased by ７８.４％ compared with the control .

不同抗冻模式对高山杨梅养分含量和果实品质的影响
在连续２ 年(２００８ — ２０１０ 年)的田间试验条件下,以?东魁"杨梅为供试植物,研究不同抗冻模式对高山杨梅产量和品质的影响.结果表明:与对照相比,各抗冻措施都能够显著减小高山杨梅叶片氮、磷、钾含量在冬季时的降低幅度,其中大棚抗冻的效果显著好于其他模式,降幅分别为１１.０％ 、２０.３％和１６.５％ ;同时,在大棚措施下杨梅叶片的含水量在越冬期内保持稳定状态;各抗冻模式都能够促进杨梅的春梢生长发育,提高春梢的氮素含量,与对照相比,大棚措施的春梢含氮量提升最高,增幅达１４.６％ ;各抗冻措施都能够显著增加杨梅果实中的氮、磷、钾含量,其中大棚措施的提高效果最好;与其他抗冻措施相比,大棚措施能够显著提高杨梅果实的单果质量、可溶性固形物、糖和维生素C 含量,降低果实的酸度,提高果实的品质;大棚措施的增产效果最好,与对照相比增产率达到７８.４％ .
