不同管理模式对设施栽培‘凯特’杏果实品质的影响

Influence of Different Culture Management to Fruit Quality of 'Kate' Apricot in Greenhouse

以精细管理和常规管理的4、6、8年生凯特杏树为试材,通过1天中不同高度区域的光照强度变化测定,不同层次的相对光照强度占树冠总体积的比例,不同枝、叶、果量的统计,以及相对应的果实品质测定分析,为杏树设施栽培建立适宜的管理模式提供技术参考。结果表明,精细管理的杏树,1天中相对光照大于30%的高光照区域占68.5%,常规管理占61.1%;精细管理的枝量、叶量、果量分别为402、4697、93个,常规管理分别为417、4997、80个;精细管理的单果重、核重、可食率与常规管理差异显著,分别为137.69g、3.85g、97.20%。因此,精细管理的杏树产量高,果实品质优良,适宜于山西省中南部杏树设施栽培应用。

4,6,and 8 years old Kate apricot trees in fine culture management and conventional culture management in greenhouse were used to study the light intensity in a day,the relative light intensity at different levels in proportion of the total volume of the canopy and the statistical capacity of different branches,leaves,fruit and fruit quality.The results showed that the rate of relative light intensity greater than 30% of total solar radiation was 68.5% and 61.1% in fine and conventional management.The number of branch,leaf and fruit was 402,4697and 93 in fine management and 417,4997,and 80 in conventional management,respectively.The weight of fruit,the weight of stone and the edible rate was 137.69 g,3.85 g,and 97.20% in fine management,significantly higher than that of conventional management.So the model of fine management will be wild used in the south and middle part of Shanxi for its high yield and high quality.
