Effects of Different N Fertilizer Applications on Substrates Properties and Tomato Production in Greenhouse

Peng Tang

Abstract

Substrates with corn straw,soil and chicken dung were used in tomato culture after decomposting.The physical and chemical properties and influence on tomato yield were studied.The results are as follows: The treatment of 60.32kg hm-2 had the best physical and chemical properties and the highest yield(60520.49kg hm-2),increasing by 25.4% compared with the control(soil culture).In addition,its cost was low compared with the control treatment.
