Screening for formulas of complex substrates for seedling cultivation of tomato and marrow squash

摘要

Organic complex substrates mixed by vinasse,mushroom residue and cattle manure as the main materials were conducted to screen proper substrates for the growth and development of tomato and marrow squash seedlings.The results indicated that it's practical to use mature vinasse,mature mushroom residue and mature cattle manure as nursery substrates.After screening for formulas of complex substrates for seedling cultivation of tomato and marrow squash,T7 and T14 had the best effect for the processing tomato and marrow squash seedling,the total primary nutrient of which were 3.07％,2.97％ respectively,more than that of CK.
