A controlled grazing experiment was conducted during the warm season of 2023 at the 77th Regiment Horse Farm in Zhaosu County, four treatments were set up: no grazing, light grazing (1 horse·hm-2), heavy grazing (4 horse·hm-2), and extreme grazing (6 horse·hm-2), and a randomized block design was adopted. The effects of grazing intensity on pasture carrying capacity were evaluated by monitoring plant community structure, diversity, standing biomass, forage nutritional quality, and by calculating digestible energy (DE) and the grading index 2001 (GI2001).The results indicated that light grazing maintained relatively a high species diversity, while the no-grazing area exhibited the best forage nutritional quality. The biomass carrying capacity was the highest under heavy grazing [0.73 horse·hm-2·(122d)-1], and the crude protein yield carrying capacity was relatively high under extreme grazing [0.99 horse·hm-2·(122d)-1]. However, these conditions were accompanied by the decline of sedges and a surge in forbs, representing an unsustainable short-term phenomenon. The PLS-PM (Partial Least Squares Path Modeling) model showed a direct negative effect of grazing intensity on GI2001 and DE. In conclusion, light grazing (1 horse·hm-2) is the suitable intensity for the Zhaosu mountain meadow steppe, effectively balancing ecological conservation and the needs for continuous grazing of Yili horses., authors=WANG Yu-jie1,2, DOU Zi-yi1,2, FANG Ju-mei1,2, WANG Ling-ling1,2, ZHENG Wei1,2, authorsList=WANG Yu-jie, DOU Zi-yi, FANG Ju-mei, WANG Ling-ling, ZHENG Wei, authorCompany=1 College of Prataculture, Xinjiang Agricultural University, Urumqi, Xinjiang 830052, China;

    放牧是草地主要的利用方式,确定适宜的放牧强度对草地保护与畜牧业可持续发展至关重要。本研究于2023年暖季在昭苏县77团马场开展控制性放牧试验,设置无牧、轻度(1 horse·hm-2)、重度(4 horse·hm-2)和极度放牧(6 horse·hm-2)4个处理,采用随机区组设计,通过监测植物群落结构、多样性、牧草现存量、营养品质,并计算消化能(Digestible energy,DE)与粗饲料分级指数(Grading index 2001, GI₂₀₀₁),评估放牧强度对草场承载力的影响。结果表明:轻度放牧维持了较高的物种多样性,无牧区牧草营养品质最优。产量载畜量在重度放牧最高[0.73 horse·hm-2·(122d)-1],粗蛋白产量载畜量在极度放牧较高[0.99 horse·hm-2·(122d)-1],但均伴随莎草科植物衰退与杂类草激增,属于不可持续的短期现象。PLS-PM(Partial Least Squares Path Modeling)模型显示放牧强度对GI₂₀₀₁和DE有直接负效应。综上,轻度放牧(1 horse·hm-2)是昭苏山地草甸草原的适宜强度,可兼顾生态保护与伊犁马连续放牧需求。

    Grazing is a primary utilization method of grasslands, and determining the appropriate grazing intensity is of crucial for grassland conservation and the sustainable development of animal husbandry. A controlled grazing experiment was conducted during the warm season of 2023 at the 77th Regiment Horse Farm in Zhaosu County, four treatments were set up: no grazing, light grazing (1 horse·hm-2), heavy grazing (4 horse·hm-2), and extreme grazing (6 horse·hm-2), and a randomized block design was adopted. The effects of grazing intensity on pasture carrying capacity were evaluated by monitoring plant community structure, diversity, standing biomass, forage nutritional quality, and by calculating digestible energy (DE) and the grading index 2001 (GI2001).The results indicated that light grazing maintained relatively a high species diversity, while the no-grazing area exhibited the best forage nutritional quality. The biomass carrying capacity was the highest under heavy grazing [0.73 horse·hm-2·(122d)-1], and the crude protein yield carrying capacity was relatively high under extreme grazing [0.99 horse·hm-2·(122d)-1]. However, these conditions were accompanied by the decline of sedges and a surge in forbs, representing an unsustainable short-term phenomenon. The PLS-PM (Partial Least Squares Path Modeling) model showed a direct negative effect of grazing intensity on GI2001 and DE. In conclusion, light grazing (1 horse·hm-2) is the suitable intensity for the Zhaosu mountain meadow steppe, effectively balancing ecological conservation and the needs for continuous grazing of Yili horses.
