摘要:
以晚熟白肉枇杷品种‘贵妃’为材料,研究不同结果母枝的性状对自然坐果和果实品质的影响,结果表明:在不疏果的情况下,梢长和叶片数是影响春梢果实穗重的主要生物学指标,其中梢长是影响夏梢果实品质的主要生物学指标;叶片数是影响夏梢坐果的主要生物学指标。贵妃枇杷生产上采用不疏果的栽培措施,若以春梢作为结果母枝,宜选择粗度大于0.9 cm、长度大于20 cm、叶片数为15~19的枝条;以夏梢作为结果母枝,则宜选择粗度大于0.7 cm、长度大于30 cm、叶片数大于20的枝条。探讨不疏果条件下白肉枇杷贵妃的果实品质,认为运用贵妃的优良性状,辅以选用优良结果母枝,贵妃枇杷不采用疏果技术而生产优质果的栽培模式是可行的。
Abstract:
Under natural conditions, correlation between the characteristics of fruiting branches and quality of Guifei loquat fruits were studied.The results indicated that the leaf number and branch length significantly affected the panicle weight.They might serve as a major index for spring shoots.For the summer shoots, it's the branch length affected markedly on the fruit quality, while the number of shoots significantly affected the fruit setting.Under the natural conditions, to produce high quality loquat, the followings were found to be desirable for the spring shoots: diameter > 0.9 cm, length > 20 cm, and 15-19 leaves per branch, while for the summer shoots: diameter > 0.7 cm, length > 30 cm, and more than 20 leaves on a branch.
