Study on the Influence of Calcium Cyanamide on Soil Microbial Quantity, Yield and Fuasrium wilt of Greenhouse Tomato
Effects of different treatments of calcium cyanamide (including 400 kg · hm-2,800 kg · hm-2,1 000 kg · hm-2) on growth,yield of tomato and Fuasrium wilt of rhizosphere soil were studied with green house cultivated tomato as the materials.The results showed that microorganisms are significantly higher than the control under calcium cyanamide treatment in the entire processing period,especially,the treatment group of 800 kg · hm-2 was the most efficient,the bacteria,fungi and actinomycetes in the soil were increased by 40.38％,45.58％ and 43.74％ respectively,and the stem diameter and stem length accelerated in the meantime; compared with control group,the incidence of Fuasrium wilt was reduced by 5.3％,and the yield was increased by 13.6％.The results showed that the moderate amount of calcium cyanamide treatment was beneficial to the accumulation of soil microbe quantity,and also had certain control effect on Fuasrium wilt.
