摘要：

为研究不同欧李品种在民勤地区的生长发育规律及营养价值，以引种的‘农大4号’、‘农大5号’、‘农大6号’3个中华钙果品种为材料，以当地野生的欧李生态苗为对照，分别对其生理生物学特性进行观测，并对营养成分进行测定。结果表明：（1）‘农大5号’叶长、宽、叶面积均大于对照、‘农大4号’和‘农大6号’。（2）引种的3个欧李品种的果纵径、横径均、单果重均大于对照，且‘农大5号’大于‘农大4号’和‘农大6号’，而果形指数‘农大5号’小于对照、‘农大4号’和‘农大6号’。（3）不同中华钙果品种中，‘农大5号’钙含量和蛋白质含量相对较高，维生素C含量相对较低。（4）中华钙果的结果量与结果枝数呈正相关，与单果重呈显著负相关关系；叶面积与结果枝数呈显著的负相关关系。由此可得，‘农大5号’生物学性状的表现性最佳，是适宜培育鲜食的优良品种。加强修剪和科学的管理技术，使植株保持适量的结果枝数和结果量，是实现优质高产的前提条件。

Abstract:

To study the growth and nutrition value of different varieties of Cerasus hmilis in Minqin area, three varieties, ‘Nongda No.4’, ‘Nongda No.5’ and ‘Nongda No.6’ of C. hmilis, were introduced as materials, and local wild seedlings were used as control, the physiological and biological characteristics were observed, and the nutritional components were determined. The results showed that: (1) the leaf length, width and area of ‘Nongda No.5’ were larger than those of the control, ‘Nongda No.4’ and ‘Nongda No.6’. (2) The longitudinal diameter, transverse diameter and fruit weight of the three introduced varieties were higher than those of the control, and ‘Nongda No.5’ was larger than ‘Nongda No.4’ and ‘Nongda No.6’, and the fruit shape index of ‘Nongda No.5’ was lower than that of control, ‘Nongda No.4’ and ‘Nongda No.6’. (3) Among different C. hmilis varieties, ‘Nongda No.5’ had the highest calcium and protein contents and the lowest Vc content. (4) The amount of fruit was positively correlated with the number of branches and negatively correlated with the weight of single fruit. There was a significant negative correlation between leaf area and number of fruit branches. Thus, ‘Nongda No.5’ has the best performance of biological characters and is an excellent variety suitable for cultivating fresh food. Scientific conservation and management technology and proper number of fruit branches are the prerequisite for high quality and high yield.
