摘要
选用城市树木修剪枝粉碎获得的新鲜木块,作为一种土壤改良添加物进行形态、盛花期、叶片相对叶绿素值(SPAD)比较试验.研究发现,添加新鲜木块显著增加了 土壤的总孔隙度、非毛管及毛管孔隙度(Ft=311.502,Fnc=226.41,F=92.384,p＜0.01),显著改变了牡丹的盛花期、株高年增量、冠幅、基径年增量、叶片SPAD,添加新鲜木块(边长为6 cm)的体积分数为60％时得到最优结果.研究结果为南方牡丹栽培提供了一种具有良好的透气性、保水性、低成本、无副作用、绿色环保等优良特性的土壤改良途径.
Abstract
This study took the fresh wood chips,obtained from the pruning and crushing of urban trees,as a soil improvement additive to compare the morphology,full-bloom stage and leaf relative chlorophyll value(SPAD),and found that the addition of fresh wood chips significantly increased the total porosity,non-capillary and capillary porosity of the soil(Ft=311.502,Fni=226.41,Fc=92.384,p＜0.01),and significantly changed the flowering period,annual increment of plant height,crown width,annual increment of basal diameter,and SPAD of leaves of peony.The optimal improvement formula for adding 60％of 6 cm fresh wood chips was proposed.The study results provide a soil improvement method with good air permeability and water retention,low cost,no negative effects,and green environmental protection for the cultivation of southern peony.
