Abstract: This paper studied the effect of fertilization on cucumber growth and yield,soil microbial biomass and soil enzyme activities in sunlight greenhouse in Loess Plateau.The results indicated that the growth and yield of cucumber were increased with application of manure and methane.Foliage application reduced the application rate of NP and manure.Fertilization had an obvious effect on the biological characteristics of soil in sunlight greenhouse.The number of bacteria was increased by manure and foliage fertilization,and that of fungi was increased by NP and methane fertilization but decreased by manure fertilization.Fertilization with manure,NP and methane also remarkably increased the number of actinomyces and the activities of urease,phosphatase and sucrase in soil.The activities of soil urease and phosphatase were increased by fertilization of manure,but little effect was found with fertilization of NP and methane.

Key words: Soil microbial biomass, Soil enzyme activity, Fertilization
