摘要
通过在火龙果园中间种百喜草、柱花草、鸭茅等牧草,研究生草栽培模式对火龙果果园土壤理化性状及微生态环境的影响,为牧草在火龙果园生态栽培上的应用提供理论依据和技术指导。结果表明:行间种植百喜草可明显改善火龙果果园土壤物理性状,土壤容重下降了16.03%,土壤总孔隙度增加了20.82%,毛管孔隙度和土壤含水量分别增加了52.10%和53.36%,土壤有机质、全氮、碱解氮含量明显增加,同时行间种植百喜草能有效提高火龙果果园相对湿度,降低气温和土壤温度,并能抑制火龙果园杂草的滋生,有效减少了果园投入,增加了果园收入。
The effect of cultivation pattern of pasture on or soil physical and chemical properties and micro-ecological environment were studied in orchard intercropping with Paspalum notatum and pitaya. This will provide great theoretical basis and technical guidance on the application of pasture in pitaya orchard. The results showed intercropping with Paspalum notatum could improve the soil physical and chemical properties of pitaya orchard,with16.03% decrease in soil bulk density,20.82% increase in total porosity and 52.10% and 53.36% increase in soil capillary porosity and water content,respectively. The content of soil organic matter,total nitrogen,alkali solution nitrogen were significantly increased and he relative humidity of pitaya orchard intercropping with Paspalum notatum was also improved with lower temperature and soil temperature. The cultivation pattern of Paspalum notatum could effectively decreased pitaya orchard input benefitting from its inhibition effect on weeds and ultimately increased the orchard income.
