摘要: 【目的】分析保水剂和微生物菌剂配施对内蒙古半干旱地区旱作大麦饲草产量、品质及土壤养分的影响,为指导旱作大麦饲草高效生产提供理论依据。【方法】试验于2023—2024年在内蒙古商都县进行,采用随机区组设计,设置单施微生物菌剂(A)、单施保水剂(B)、保水剂配施微生物菌剂(AB)和不施用保水剂和微生物菌剂(CK)4个处理,分析不同处理下旱作大麦饲草产量、品质以及土壤养分的变化情况。【结果】旱作大麦鲜草产量、干草产量均表现为AB>A>B>CK;两年数据显示,AB处理粗蛋白含量、粗脂肪含量、相对饲用价值较CK分别提高了2.65~3.35个百分点、6.67~8.90个百分点、6.21%~42.94%。不同处理均能不同程度地改善土壤养分,AB处理与CK、A处理、B处理相比,土壤有机质含量提高5.82%~28.40%、全氮含量提高2.84%~43.72%、全磷含量提高2.63%~76.11%、全钾含量提高-2.69%~14.17%、碱解氮含量提高11.83%~60.96%、速效磷含量提高7.89%~31.88%、速效钾含量提高4.41%~20.34%。相关性分析表明,土壤有机质、全氮、全钾、速效钾含量是影响旱作大麦干草产量的主要因素;土壤全氮、全钾、碱解氮含量是影响旱作大麦饲草品质的主要因素。【结论】保水剂配施微生物菌剂提高了旱作大麦饲草的产量和品质,改善了土壤养分,可在内蒙古半干旱地区进行推广验证。

Abstract: 【Objective】To analyze the effects of combined application of water-retaining agent and microbial agent on forage yield,quality,and soil nutrients of dryland barley in the semi-arid region of Inner Mongolia,thereby providing a theoretical foundation for efficient forage production. 【Methods】ield experiments were conducted in Shangdu County,Inner Mongolia,from 2023 to 2024 using a randomized block design. Four treatments were established:microbial agent alone(A),water-retaining agent alone(B),combined application of water-retaining agent and microbial agent(AB),and a control without the application of a water-retaining agent and microbial agent(CK),to analyze the changes in forage yield,quality,and soil nutrients of dryland barley under different treatments.【Results】Fresh grass yield and hay yields of dryland barley ranked as AB>A>B>CK. Two-year data showed that,compared with CK,the AB treatment increased crude protein content by 2.65-3.35 percentage points,crude fat content by 6.67-8.90 percentage points,and relative feed value by 6.21%-42.94%. All treatments improved soil nutrients to varying degrees. Compared with CK,A treatment,and B treatment,the AB treatment increased soil organic matter content by 5.82%-28.40%,total nitrogen content by 2.84%-43.72%,total phosphorus content by 2.63%-76.11%,total potassium content by -2.69%-14.17%,available nitrogen content by 11.83%-60.96%,available phosphorus content by 7.89%-31.88%,and available potassium content by 4.41%-20.34%. Correlation analysis indicated that soil organic matter,total nitrogen,total potassium,and available potassium were the main factors influencing hay yield of dryland barley,whereas soil total nitrogen,total potassium,and available nitrogen content were the main factors affecting forage quality of dryland barley.【Conclusion】Combined application of water-retaining agent and microbial agent enhances forage yield and quality of dryland barley and improves soil nutrients,warranting further promotion and validation in the semi-arid region of Inner Mongolia.
