This study aims to explore the growth and production potential of ssp. "Ulanshalin," a pioneer species of soil and water conservation, after being planted in the Yellow River Basin area with serious soil erosion. An analysis of the differences in photosynthesis and fruit yield of plants grown in two typical soils in the watershed is key to understanding whether local conditions are suitable for the growth and yield of as well as the impact of the plants on soil and water conservation.
During the growing season, diurnal changes in the gas exchange parameters of -like plants growing in Loess soil and Aeolian soil were continuously monitored, and the effects of total nitrogen (TN) and other elements on the net photosynthetic rate ( ) of the plants were analyzed and compared in the two different soil types. The morphological and quality differences of fruits were also compared after reaching the ripening stage.
(1) There was a significant difference in the composition of Loess soil and of Aeolian soil. The organic matter content and AK content of the Loess soil was significantly higher than in the Aeolian soil, and the pH was closer to neutral. However, the TK content, TP content, and AP content of the Aeolian soil were slightly higher than in the Loess soil, the pH was higher, and it was alkaline. (2) After controlling the light and temperature, with all other external factors consistent, the daily variation trend of , , and in the leaves of plants growing in the two different soils were basically the same. There were differences, however, in when these factors reached their peaks. Soil composition had an impact on the photosynthetic characteristics of , with TN, TP, AP, and SOM being the main factors promoting the photosynthetic rate of . The peaks of , , and of plants growing in Aeolian soil were higher than those growing in Loess soil. (3) The average stem length of plants growing in Aeolian soil was higher than the plants growing in Loess soil. The number of thorns in the branches of plants in the Aeolian soil was relatively low, and the weight of 100 fruits (28.28 g) was significantly higher than the weight of 100 fruits of the plants grown in Loess soil (11.14 g).
The results of this study show that in the Yellow River Basin area, Aeolian soil is more conducive to the growth of plants than Loess soil. plants growing in Aeolian soil had good adaptability and stress resistance, and a larger potential for fruit production. These findings provide insights for ecological restoration and the creation of economic value in the Yellow River Basin area.
本研究旨在探讨在黄河流域水土流失严重地区种植沙柳后，其生长和生产力的潜力。分析在流域内两种典型土壤中生长的植物的光合作用和果实产量差异，对于了解当地条件是否有利于植物的生长和产量以及植物对水土保持的影响至关重要。
在生长季节，连续监测在黄土和风沙土中生长的类植物的气体交换参数的日变化，并在两种不同土壤类型中分析和比较总氮（TN）和其他元素对植物净光合速率（）的影响。在达到成熟阶段后，还比较了沙柳果实的形态和品质差异。
（1）黄土和风沙土的组成有明显差异。黄土的有机质含量和 AK 含量明显高于风沙土，pH 值更接近中性。然而，风沙土的 TK 含量、TP 含量和 AP 含量略高于黄土，pH 值较高，呈碱性。（2）在控制光照和温度的情况下，当所有其他外部因素保持一致时，在两种不同土壤中生长的植物叶片的 、 和 的日变化趋势基本相同。然而，这些因素达到峰值的时间存在差异。土壤组成对 的光合特性有影响，TN、TP、AP 和 SOM 是促进 光合速率的主要因素。在风沙土中生长的植物的 、 和 的峰值高于在黄土中生长的植物。（3）在风沙土中生长的植物的平均茎长高于在黄土中生长的植物。在风沙土中生长的植物的枝条上的刺的数量相对较低，100 个果实的重量（28.28 克）明显高于在黄土中生长的植物的 100 个果实的重量（11.14 克）。
本研究结果表明，在黄河流域，风沙土比黄土更有利于沙柳植物的生长。在风沙土中生长的植物具有良好的适应性和抗逆性，果实产量潜力较大。这些发现为黄河流域的生态恢复和创造经济价值提供了参考。
