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.
