土壤酸化改良剂对平邑甜茶幼苗生长的影响
Effect of Acidified Soil Amendments on Seedling Growth of Malus hupehensis
摘要
Abstract
One-year-old Malus hupehensis seedlings were used to study the effects of different acidi-fied soil amendments on plant growth and development .The amendments were CaO (T1), CaO+MgSO4 +ZnSO4 +B (T2), CaO+aspartic acid (T3), CaO+chitosan (T4), CaO+polyacrylamide (T5) respective-ly.The results showed that the aboveground , underground and total weight , leaf area and chlorophyll content of T1~T5 treatments were significantly higher than that of CK .Compared with T1 treatment, all the growth indexes increased under T2~T5 treatments, and the highest ones appeared in T 2 treatment.Therefore, CaO+MgSO4 +ZnSO4 +B had the best effect on acidified soil improvement .关键词
