| 摘 要： | 以玉米秸秆腐解物为覆盖材料,研究了不同厚度覆盖对园林土壤理化性质的影响,结果表明:覆盖可以显著降低表层的土壤容重,具有保水作用,如玉米秸秆覆盖120 d时,覆盖3 cm的效果最佳;覆盖180 d后,均可显著增加土壤养分含量,减少化肥和农药的使用量;覆盖6 cm处理的杂草抑制率达100%;覆盖还能减缓土壤温度变化的幅度。因此,玉米秸秆园林覆盖可省水、省肥、省工,符合资源节约、环境友好型园林的要求,值得推广应用。

| Abstract: | The corn straw compost was used as the mulch,the effects of mulch treatment with different thicknesses on the physical and chemical properties of soil in gardens were studied.The results showed that corn straw mulch could markedly reduce the bulk density of surface soil and increase the soil moisture content.The ideal mulch thickness was 3 cm if the landscape was covered by corn straw compost for 120 days.After 180 days mulch treatment with different thicknesses,the soil nutrient content was significantly ... |
