| 摘 要： | 【目的】研究影响中国沙棘生长的关键光合指标、生理指标及土壤含水量，并对中国沙棘苗木生长状况进行综合评价，筛选出最优的整地方式和保水措施。【方法】以天山北坡前山带不同整地方式和保水措施下种植的中国沙棘为研究对象，设置水平沟整地、穴状整地与覆膜、膨润土的不同组合处理，分析不同造林技术对中国沙棘生长指标、光合特性、生理指标的影响。【结果】(1)水平沟整地的土壤含水量、造林成活率、新梢生长量显著高于穴状整地(P<0.05),覆膜、膨润土的土壤含水量、造林成活率、新梢生长量显著高于对照(P<0.05);(2)影响中国沙棘生长的关键生理指标为可溶性蛋白、超氧化物歧化酶，光合指标为蒸腾速率、气孔导度，土壤含水量指标5月土壤含水量、8月土壤含水量；(3)水平沟整地-覆膜-膨润土处理的评分最高，水平沟-覆膜处理次之；其造林成活率分别为80.63%、72.26%。【结论】中国沙棘在天山北坡前山带造林的综合配套技术为水平沟整地-覆膜-膨润土综合技术、水平沟整地-覆膜综合技术。

| Abstract: | 【Objective】 To reveal the key photosynthetic indicators, physiological indicators and soil water content that affect the growth of H.rhamnoides, and comprehensively evaluate the growth status of its seedlings, and screen out the best land preparation methods and water conservation measures. 【Method】 Hippophae rhamnoides planted under different land preparation methods and water conservation measures on the northern slope of Tianshan Mountain were taken as the research object, through different combinations of horizontal ditch site preparation, pit-shaped site preparation, film mulching, and bentonite, the effects of different afforestation techniques on the growth indicators of H.rhamnoides were analyzed. 【Result】 (1) The soil water content, afforestation survival rate, and new growth rate of horizontal furrow site preparation were significantly higher than those of cave-shaped land preparation (P<0.05), and the soil water content, afforestation survival rate and new growth rate of mulch and bentonite were significantly higher compared with control (P<0.05); (2) The key physiological indicators that affected the growth of H.rhamnoides were soluble protein and superoxide dismutase, photosynthetic indicators were transpiration rate, stomatal conductance, and soil water content indicators were May soil water content and August soil water content; (3) The comprehensive evaluation results showed that the horizontal furrow soil preparation-film mulching-bentonite treatment had the highest score, followed by the horizontal furrow-film mulching treatment; their afforestation survival rates were 80.63% and 72.26%, respectively. 【Conclusion】 The comprehensive supporting technologies for H.rhamnoides afforestation in the front mountain belt of the northern slope of Tianshan Mountains are: Horizontal ditch site preparation - film mulching - bentonite, horizontal ditch site preparation - film mulching. |
