“木奇”覆盖对城市绿地土壤主要理化性状的影响
Study on the effect of "Muqi" on main physicochemistry properties of soil in urban green space
摘要
Abstract
Taking the green space soil of Henan Agricultural University campus as an example,and selecting the soil alkalized nitrogen,available phosphorus,available potassium,organic matter,pH value,temperature,water holding capacity,and permeability as indicators,field experiments and control experiments were conducted to explore the effect of "Muqi" (Mulch) on urban greenland soil.The result showed that "Muqi" could effectively increase the content of soil alkali-hydrolyzable nitrogen,available kalium and soil organic matter,and the content of these indicators of the soil covered with "Muqi" increased by 41.74％,53.22％ and 22.20％ respectively,compared with the bare soil;"Muqi" could also reduce the soil pH value and keep the soil temperature steady,and 9 cm treatment worked best;Besides,"Muqi" had the advantage of maintaining soil moisture and delaying the overland runoff,and the water content and permeability of the soil covered with "Muqi" increased by 23.60％ and 61.97％,respectively,compared with the bare soil.关键词
