Influences of Mushroom Residue,Peat and Vermiculite Matrix Product on the Growth Characteristics of Tomato Seedlings
摘要
Abstract
The study focused on the influences of mushroom residue,peat and vermiculite matrix product on the growth characteristics of tomato seedlings.After matrix treatment,mushroom residue was mixed with turf and vermic-ulite for tomato seedling culture.The compound matrix mushroom residue treatment products were added with differ-ent proportions:0,33%,50% and 67% respectively,and the survival rate and growth characteristics of the tomato seedling were tested 25,45,65 days after sowing.Statistical analysis showed that the survival rate of tomato seedling with compound matrix T1 ,T2 and T5 reached 1 00%,3.3% higher than CK,the survival rate of tomato seedling with T4 and T5 were lower than CK 23.4% and 33.4% respectively.After comparison of 45 d tomato seedling height,stem diameter and root development indicators,those of T3 and T4 were significantly lower than those of CK, T1 ,T2 and T5.However,with the growth of the tomato seedling,at 65 d root lengths of T3 and T4 were significantly higher than those of CK,seedling height and stem diameter had no significant difference with those of CK,and the stem diameter and root lengths of T1 ,T2 and T5 showed no significant difference with CK,and the seeding height were higher than those of CK.The study indicated that the growth index of treatment T1 (mushroom residue∶peat∶vermiculite =1 ∶1 ∶1 )was higher than other treatments,and a relative high additive proportion of mushroom residue may inhibit the initial growth of tomato seedlings to some extent,which may further influence the accumulation of seedling biomass above the earth,yet as the seedlings keep growing,such inhibition was decreasing.At the later de-velopment stage of the seedling,increasing the additive proportion of mushroom residue can further promote the de-velopment of the tomato seedling root and enhance the biomass accumulation of the plant.关键词
