| 摘 要： | 目的]研究气候变化对四川早熟桃生产的影响。方法]以四川盆地桃主产区（龙泉山脉）3个早熟桃品种为材料，分析比较其连续2年的枝梢生长、果实品质、熟期、产量及经济效益差异。结果]20lO年早熟桃一、二、三次枝生长量较2009年增加12．47％～50．78％，且三次枝数量明显增加，果实生长发育进程变缓，成熟期推迟4—8d，果实单果重略有下降，可溶性固形物、vc、可溶性总糖、总酸含量以及糖酸比下降4．76％～60．67％，果实批发价格和单位面积产值显著降低。结论]受持续低温阴雨天气影响，2010年四川早熟桃经济效益明显下降。

| Abstract: | Objective] The aim was to study the influence of climate change on the early peach in Sichuan Province.Method] With 3 early peach varieties as the tested materials,the shoot growth,fruit quality,maturity,yield and economic benefit differences of the peach in consecutive 2 years were analyzed and compared.Result] The increments of the first,second and third shoot of the early peach in 2010 were 12.47%-50.78% higher than that in 2009 and the number of the third shoot was increased significantly.The fruit growth and development process became slowly,the maturity stage of fruit was delayed by 4-8 d and the weight per fruit was decreased slightly.The content of soluble solids,Vc,total soluble sugar,total acid and sugar-acid ratio were decreased by 4.76%-60.67%.The fruit wholesale prices and output value per unit area were reduced significantly.Conclusion] Under the effect of the sustainable low temperature and rainy weather,the economic benefit of the early peach was decreased obviously in 2010 in Sichuan Province. |
