以园林绿化废弃物堆肥为试材,采用三角枫栽植试验和覆盖土壤温湿度调节试验的方法,研究堆肥对三角枫苗期生长发育及土壤质量的影响,以期为园林绿化废弃物堆肥在苗木生产及改良土壤方面提供一定的科学依据。结果表明:施用堆肥能够显著增加三角枫的株高,同时三角枫胸径及冠幅均大于空白对照,试验中以3 000kg/667m2的施用量植物长势最佳。堆肥覆盖土壤可有效降低土壤容重,改善土壤板结黏闭等状况。覆盖物有在寒冷天气里保温,在炎热天气里降温的作用。覆盖物具有保水功效,且保水效果随覆盖厚度的增加呈现递增趋势。
Taking the composting of landscaping wastes as the test material, the effects of compost on the growth and soil quality of the Aralia elata were studied by using the planting methods of the acer melon and soil temperature and humidity adjustment test. And improve the soil to provide some scientific basis. The results showed that the composting application could significantly increase the height of the triangular maple, while the DBH and crown width of the triangular maple were larger than that of the blank control. In the experiment, the plant growth was the best with the dosage of 3 000 kg / 667m2. Composting soil cover can effectively reduce soil bulk density, improve soil compaction and other conditions. Coverings have insulation in cold weather, the role of cooling in hot weather. Covering has water retention effect, and the water retention effect increases with the increase of cover thickness.
