不同限根栽培对枸杞果实性状及营养品质的影响

Effect of Rooting-Zone Restriction on Fruit Characters and Nutrient Quality of Wolfberry

为探索根域限制栽培条件对不同枸杞品种的果实性状及主要营养成分的差异,以宁杞1号、宁杞7号、1401、1402为研究材料,采用果实性状调查和主要营养成分测定等方法,研究根域限制栽培模式下4个宁夏枸杞品种的果实性状及主要营养成分的差异。结果表明:(1)60 cm根域限制栽培模式下,4个品系在果实性状和产量上的综合优势依次为1402>1401>N7>N1;(2)不同根域限制栽培的宁杞7号单株产量具有明显产量优势,具体表现为X80、X60和X40相较CK分别增产131.90%,110.86%和52.22%;(3)对比不同限根栽培模式下4种枸杞品种(系)主要营养成分差异,甜菜碱和VC含量相较CK均显著增加,且在多糖、总糖、类胡萝卜素、总黄酮含量上存在不同程度的差异。

In order to explore the difference of root-zone restricted cultivation conditions on the fruit characters and main nutrients of different wolfberry varieties,Ningqi 1,Ningqi 7,1401 and 1402 were used as research materials,and methods such as fruit character investigation and main nutrient composition determination were adopted.The differences in fruit characteristics and main nutrients of four Ningxia wolfberry varieties under the root zone restriction cultivation mode were studied.The results showed that:1)Under the 60 cm root zone restriction cultivation mode,the overall advantages of the four lines in fruit traits and yield were 1402>1401>N7>N1;(2)The yield per plant of Ningqi 7 cultivated in different root domains had obvious yield advantage,which was manifested in the increase of X80,X60 and X40 by 131.90%,110.86%and 52.22%,respectively,when compared with CK;(3)Compared the differences in the main nutrient components of the four Lycium barbarum varieties(lines)under different root-restricted cultivation modes,the content of betaine and VC was significantly increased compared to CK,and there were varying degrees of polysaccharide,total sugar,carotenoid,and total flavonoid content difference.
