香菇菌糠不同粒径含量对油松生长的影响
Effects of different shiitake residue substrate particle size ratio on Pinus tabulaeformis growth
摘要
Abstract
Physical characters of different shiitake ( Lentinula edodes) residue substrate particle size ratio in cultivation and its effect on growth indexes of Pinus tabulaeformis was tested. The results showed as follows. When shiitake residue substrate was taken as the cultivating matrix classified according to the grades of particle size such as ≥2-5 mm,≥0.5-2 mm and <0.5 mm, and remixed, the physical characters in 5 treatments were stable and the various physical indexes before and after cultivation met the requirements of ideal matrix. Biomass, growth indexes and physiological indexes of P. tabulaeformis in 5 treatments were better than the control. When shiitake residue substrate was taken as the matrix in the order of particle size ratio of 1∶3∶1 from large to small, the growth conditions of P. tabulaeformis were the best, the seedling quality index was 0.166, the highest, the dry mass of terminal bud was 2.88 mg·tree-1 , the highest, and all the other physiological indices were the highest except irregular chlorophyll. Therefore, the shiitake residue substrates with particle sizes ≥2-5 mm, ≥0. 5-2. 0 mm and <0. 5 mm and in the ratio of 1∶3∶1 were the most suitable for P. tabulaeformis growing, the more content of medium and small particle sizes, the more vigorously the trees grew.关键词
