呼伦贝尔地区家庭牧场牛粪粗处理施肥对草场质量影响分析

该实验在呼伦贝尔地区家庭牧场选择样地,把牛粪自然干燥后粉碎处理,并通过合理适当的还草归土和治理沙地,是呼伦贝尔地区各家庭牧户现有发展水平下最佳的低成本、高效粗制处理方式,如能运用合理方式,以适当的量还田还草,有一定的改善草场质量效果。通过在不同土壤条件下,在单位面积之内进行不同浓度的牛粪胁迫处理,探索出不同类型草场的不同粪便浓度胁迫条件下植被生长的最佳程度和能承受的上限阔值,对其他的相关研究和实际生产提供理论和实验依据。

In this experiment,the sample plots were selected in the family pastures in Hulunbuir area,and the cow manure was naturally dried and crushed.Reasonable and appropriate return of grass to soil and control of sandy land is the best way of low-cost and efficient rough treatment under the current development level of family herdsmen in Hulunbuir area.If it is used in a reasonable way and in an appropriate amount,it can improve the quality of grassland to a certain extent.Through the treatment of different concentrations of cow manure stress per unit area under different soil conditions,the best degree and upper limit width of vegetation growth under different fecal concentration stress in different types of grasslands were explored,so as to provide theoretical and experimental basis for other related research and practical production.
