Study on Responses of Yield and Quality of Angelica sinensis In Yunnan Province to Altitude and Climatic Factors
By investigating the effects of different altitudes and climatic factors on the yield and quality of Angelica sinensis in Yunnan province, this study provides a scientific basis for the precise selection of cultivation areas for A. sinensis in Zhaotong City. Using A. sinensis seedlings as experimental materials, three experimental bases with distinct geographical and climatic environments were established. After transplantation and harvesting, the influences of altitude, temperature, precipitation, and light on yield and the content of extract, volatile oil, ferulic acid were analyzed. The results showed that within the ecological regions suitable for cultivating A. sinensis in Zhaotong City, altitude and precipitation showed significant positive correlations with yield and the content of extract, volatile oil, ferulic acid, while temperature exhibited significant negative correlations with those indexes. Light had significant negative correlations with yield and extract content but showed no significant correlations with the content of volatile oil and ferulic acid. Principal component analysis revealed that the comprehensive yield and quality ranking from high to low was: S3 > S2 > S1. OPLS and variable importance in projection analysis indicated that the comprehensive yield and quality was significantly negatively correlated with temperature, significantly positively correlated with altitude and precipitation, and weakly negatively correlated with light. The influence intensity of environmental factors on the comprehensive yield and quality was: temperature > altitude > precipitation > light, with temperature and altitude being the dominant factors. In conclusion, the altitude and climatic factors in different regions of Zhaotong City have a significant impact on the yield and quality of A. sinensis. The higher altitude areas in the northern and central parts of Zhaotong City are more suitable for the production of A. sinensis, while in the southern part, higher altitude areas should be selected with attention to drought management and sun shading.

为探讨干旱半干旱区旱地覆膜栽培当归土壤温度变化特征及其对当归产量的影响,研究当归覆膜与不覆膜条件下,不同观测时刻、不同土层土壤温度的变化特征及当归产量, 研究结果表明:不同测定位置不同土层温度随气温的变化而变化,膜上温度高于露地温度;不同土层土壤温度的月变化为:膜上土壤温度(A)>膜侧土壤温度(B)>膜间土壤温度(C)>露地土壤温度(CK)。膜上、膜侧、膜间和露地土壤温度随土层深度增加而下降。膜上温度最高,膜上土层温度下降最快。覆膜栽培能增加当归的产量,覆膜栽培产量为2975.80 kg/hm2,平均高于露地栽培16.53%,露地栽培产量为2553.68 kg/hm2,当归覆膜栽培对土壤地温有显著的影响,当归在10cm至25cm土层温度16~21℃时产量提高。

通过探索岩黄连对覆膜和光照的需求,为昭通地区岩黄连高效栽培提供技术指导。以岩黄连幼苗为试验材料,对不同覆膜处理(覆膜、未覆膜)和遮阴度处理(0%、30%、50%、70%、90%)下岩黄连的生长及产量进行测定,并进行综合评价。结果表明,覆膜处理的平均移栽成活率达到94.44%,比未覆膜处理组提高9.67%。覆膜处理的全株鲜重、全株干重分别达到0.728、0.150 kg/m<sup>2</sup>,比未覆膜处理组分别提高65.45%、40.59%。50%遮阴度处理的全株鲜重、全株干重、根鲜重、根干重、株高、蒴果长度、花序数、蒴果数、种子数均达到最大值。通过逐步回归分析和通径分析发现,株高、蒴果数、蒴果长度、花序数是种子数的决定性因素,且对种子数的正相关作用依次增强。综合分析,覆膜和50%遮阴度对岩黄连的移栽、生长和产量最佳,研究结果可为昭通地区岩黄连高效栽培提供理论依据。
