Effects of Different Fertilization on Soil Physical and Chemical Properties of Ninghua Oil Tea Garden
Fertilizer plays an important role in the growth and quality of Camellia oleifera.In this study,the purple soil of Camellia oleifera garden in Ninghua County,Fujian Province,was taken as the research object.The comparison experiment was set between the application of compound fertilizer and water-holding microbial organic fertilizer to study the effects on soil fertility and the growth of Camellia oleifera.The results showed that,1)both water-retaining microbial organic fertilizer and traditional com-pound fertilizer could increase soil nutrients and soil microbial activity in the short term.2)Compared with traditional compound fertilizer,water-holding microbial organic fertilizer can increase soil nutrients more efficiently in the short term.Soil organic matter increased by 12.4%,total nitrogen and total carbon increased by 160.8%and 231.63%,respectively.3)Water-holding microbial organic fertilizer has better water-holding effect,and a buffering effect on soil pH,which can effectively solve the problem of soil water conservation in soil erosion areas.Proper utilization of local chicken manure as the base of water-retaining microbial organic fertilizer can effectively solve the problem of soil pollution of poultry manure,which is of great significance to promote the increase of local farmers'income.
