施用生物有机肥对可可苗期生长及土壤酶活性的影响
Effects of Different Bio-organic Fertilizer Application on Cacao Plant Growth and Soil Enzyme Activities
摘要
Abstract
Green house pot experiments were carried out to investigate the effects of different bio-organic fertilizer application on cacao(Theobroma cacao.L)seedlings growth and soil enzyme activities.The main results obtained were listed as follows:application of bio-organic fertilizer could obviously increase cacao plant dry weights,total root length,root diameter,root surface area and root volume compared with the control and cattle manure treatments; application of bio-organic fertilizer BIOa significantly increased net photosynthetic,transpiration rate and Chlorophy by169％,270％ and 28％,respectively compared with the control; application of bio-organic fertilizer BIOa obviously increased soil acidic phosphatase,urease and invertase activities by 98.7％,92.2％ and 83.2％,respectively compared with the control.In conclusion,the application of bio-organic fertilizer can effectively promote cacao above-ground and root growth,moreover,significantly increase soil enzyme activities.关键词
