- 摘要:
- 以红果枸杞“宁杞7号”“宁农杞9号”和黄果枸杞‘W1230’‘W1329’4个枸杞品种（系）为研究对象，采用CI600植物根系监测系统对5—7月枸杞根系形态特征进行动态监测，并同步调查测量枸杞植株地上部分生长量，为枸杞品种区域化种植及施肥措施提供参考。结果表明：在同样生态环境及水肥管理措施下，不同品种（系）枸杞的地下及地上生长量各不相同且差别较大；枸杞根长、根投影面积和根表面积分别与枸杞枝长、枸杞枝粗度具有极显著相关；“宁杞7号”‘W1230’‘W1329’的根系主要分布在40～60 cm土层，“宁农杞9号”枸杞根系主要分布在0～40 cm土层；系统聚类分析结果表明，‘W1230’‘W1329’“宁杞7号”的根系聚为一类，“宁农杞9号”单独聚为一类。该研究可为枸杞区域化种植及枸杞栽培提供参考。
- Abstract:
- Four wolfberry varieties (lines),including ‘Ningqi 7’‘Ningnongqi 9’ and yellow fruit wolfberry ‘W1230’‘W1329’ were used as research targets.The CI600 plant root system was used to monitor the morphological characteristics of the roots of wolfberry from May to July,and the growth of wolfberry in aboveground parts was measured simultaneously.The results showed that under the same ecological environment and management measures of water and fertilizer,the underground and aboveground growth of different varieties(lines) were different,indicating that the adaptability of different varieties (lines) of wolfberry to the environment were different;the wolfberry root length,root projected area and root surface area were significantly correlated with the length of wolfberry branches and the diameter of wolfberry branches,respectively.The root system of ‘Ningqi 7’‘W1230’‘W1329’ were mainly distributed in the soil layer of 40-60 cm,the main distribution of‘Ningnongqi 9’ in the 0-40 cm soil layer range.The roots of ‘W1230’‘W1329’‘Ningqi 7’ were clustered into one category and ‘Ningnongqi 9’ alone into a category.The study could provide reference for the most basic agricultural measures such as the regional planting of wolfberry and the fertilization in wolfberry cultivation.
