Abstract
The use of wheat-straw residue substrate as component of mixed substrate for sweet pepper seedling growth instead of peat was studied.Straw residue substrate,peat and vermiculite were mixed in various ratios.Prior to sowing,some physical and chemical properties of the seedling substrates were determined and the growth of sweet pepper seedling was also studied.The results showed that,with the increase of wheat residue content in the mixture,the dry bulk density,total porosity,water holding porosity,nutrient concentrations,electrical conductivity and caption exchange capability all had a tendency to increase,whereas the aeration porosity had a tendency to decrease;When the percentage of wheat-straw residue substrate was 36%(straw residue∶ peat∶ vermiculite=36∶ 54∶ 10),the dry weight per plant,strength index,total content of chlorophyll of the sweet pepper seedlings exceeded control by 10.6%,8.4%,2.1% and the net photosynthetic rates of the sweet pepper seedlings significantly exceeded control by 7.8%.Thus,the formula of 36% straw residue with 54% peat and 10% vermiculite was ideal for the growth and development of sweet pepper seedlings.
