【摘要】 以一年生、当年生红翅槭为试材,通过对红翅槭幼苗生长及生理指标进行测量,研究了秋季施用不同用量菌渣有机肥对红翅槭幼苗生长的影响,以期筛选出相对合理的有机肥用量。结果表明:不同用量的有机肥均对红翅槭幼苗生长有促进作用,3个施肥处理中,促进红翅槭幼苗生长的最优用量是单株红翅槭幼苗菌渣有机肥施用量500g,显著提高了红翅槭幼苗生长,对当年生与一年生红翅槭苗地径、苗高、叶面积、叶绿素含量的影响均达显著水平。更多还原

【Abstract】 The current-year and annual Acer fabri Hance were used as materials,the effect of organic fertilizer made by spent mushroom substrates on the seedling growth of Acer fabri Hance was studied,and the suitable organic fertilizer dosage were screened.The results showed that seedling growth were promoted by adding different dosage of organic fertilizer.And organic fertilizer 500 g per plant,which had significant influence on ground diameter,seedling height,leaf area and chlorophyll content of current-year and annual Acer fabri Hance seedling,was optimal among the three kinds of organic fertilizer.It significantly promoted the seedling growth of Acer fabri Hance.更多还原
