一次性施入牛粪对土壤肥力和土壤微生物及酶活性的影响
Effects of One-time Cattle Manure Application on Soil Fertility, Microorganism and Enzyme Activity
摘要
Abstract
In order to reduce labor force and expound the improved effect of one-time organic fertilizer application on soil in hilly area, a field experiment was set up in April 2016 to November 2017.This study arranged different a amount of cow manure treatment and conventional fertilization was regarded as control to study the effects of one-time application of cow manure on soil fertility, microbial biomass and enzyme activity. The results showed that compared with conventional fertilization(100000 kg/hm2,CK),the treatments of 200000 kg/hm2(T1),300000 kg/hm2(T2)and 400000 kg/hm2(T3)cow manure increased soil organic matter,available nitrogen,available phosphorus and available potassium in 20~40 cm and 40~60 cm soil layers and the 300000 kg/hm2(T2)treatment was the best.In May,the contents of organic matter in different soil layers treated the 300000 kg/hm2(T2) were 56.82 % and 108.20 % higher than that of CK, respectively.The 300000 kg/hm2(T2)treatment improved the contents of alkaline N,available P and available K at 20~40 cm and 40~60 cm soil layers in June and were 4.45-fold, 7.28-fold, 2.15-fold and 2.99-fold, 2.19-fold (1.81-fold) of the control, respectively. Activities of soil urease, phosphatase and sucrase were increased significantly by the 300000 kg/hm2treatment during all growth and development period of apple.Compared with CK,300000 kg/hm2(T2)treatment raised obviously the number of bacteria and actinomycetes in different soil layers and inhibited the growth of fungi. In conclusion,one-time application of 300000 kg/hm2cow manure in the orchard management of the hilly area was most suitable,which not only reduced the labor of the orchard,but also enhanced soil fertility and soil biological activity.关键词
