Abstract

Abstract: "The effects of different irrigation quantity and mulches on the growth and yield of sweet pepper with organic soil substrate in greenhouse were studied.The soil temperature and oxygen content in soil were compared.The photosynthetic rate and chlorophyll content of leaves were analyzed.The results showed that the substrate temperature and oxygen content in soil were changed with different mulches;soil temperature in film mulch was much higher than that in straw mulch.The oxygen content was negative correlated with the water irrigation.The oxygen content in straw mulch was much higher than others.The photosynthesis of sweet pepper cultivated surface covering with green grass was higher than any other treatments.The yield of sweet pepper with middle irrigation quantity was higher than low and high irrigation quantity.The fruit yield of sweet pepper cultivated soil covering with green grass was the best treatments.
