摘要
甜角是苏木科酸豆属常绿乔木,是新近引进的热带经济树种,其果实具有重要的食用和药用价值。本文在区域试验的基础上,全面调查甜角生长状况及各试验地的气候因子,探讨了甜角的生长规律及气候因子对其生长的影响。结果表明,甜角株高、地径和冠幅呈"S"型生长,符合逻辑斯蒂生长模型,且与其生殖发育过程高度吻合;甜角在各试验点的生长速度差异显著,平均温度和≥10℃的积温分别是株高和地径的主要影响因子,热量成为甜角推广种植过程中需要重点考虑的关键因素。
Tamarindus indica Linn, an evergreen arbor, belongs to Caesalpiniaceae, were introduced to China recently, and it is a tropical non-wood forest with high edible and medicinal value. In this paper, relevant data of its growth and climatic factors were collected based on regional trials, and its growth rhythm and the effect of cli- matic factors were analyzed. The results showed that the growth curve of basal diameter, high and crown width were in a ＂s＂ shape. Its growth accorded with the Rogistic growth model and the process of reproductive develop- ment. There were significant difference in growth rate among different experimental sites, and the mean tempera- ture and accumulated temperatures above 10℃ were the main impact factors of its high and basal diameter respec- tively, and heat should be considered as the critical factor in its planting for promoting.
