冬绿肥二月兰间作及翻压对北方桃园生长环境及果实品质的影响

摘要

研究二月兰间作及其翻压对北方桃园生长环境及果实品质的影响.结果表明:二月兰翻压或自然生长处理能够维持土壤温度、保持土壤水分,显著防除艾蒿等杂草,降低土壤容重,提高了土壤有机氮、有机碳、有效氮含量及微生物数量,为桃树生长发育提供适宜的土壤环境;增加果桃Vc、可溶性糖和可溶性固形物含量.%The effect of Orychophragmus violaceus cover on the soil environment and the peach quality in a peach orchard in the North was studied through Orychophragmus violaceus plowing, Orychophragmus violaceus cover or simply weeding. The results showed that the Orychophragmus violaceus cover and plowing could maintain the soil temperature, hold the soil water, inhibite weeds, decrease soil volume weight, increase the soil organic carbon, organic nitrogen and microorganism. The soil environment was improved. The fruit quality including vitamin C, soluble sugar and soluble solid content had increased.
