不同有机肥对蓝莓园土壤理化性质及蓝莓光合特性的影响

Effects of Organic Fertilizers on Soil Physicochemical Properties and Blueberry Photosynthetic Characteristics

为研究不同有机肥处理对蓝莓园土壤理化性质及蓝莓生理特性的影响,设置了兔粪、羊粪和豆饼肥三种不同处理,3年后测定蓝莓园土壤及蓝莓叶片、果实的相关指标。结果表明:羊粪处理后的土壤p H值显著低于豆饼肥和兔粪处理;土壤有机碳含量为兔粪处理最高、豆饼次之,羊粪最低;蓝莓叶片总叶绿素含量以兔粪处理最高,果实可溶性固形物含量为豆饼>兔粪>羊粪。综上,兔粪处理相较于羊粪和豆饼,对蓝莓的生长和生产作用更大。

In order to study the effects of different organic fertilizer treatments on the physical and chemical properties of the blueberry orchard soil and the physiological characteristics of ground blueberries,three different treatments were set up as rabbit manure,sheep manure and bean cake fertilizer.Three years later,soil samples,blueberry leaves and fruit samples were collected.The results showed that the soil pH under sheep manure treatment was significantly lower than the other two treatments.The soil organic carbon content under rabbit manure treatment was the highest,followed with cake fertilizer,and sheep manure conducted the lowest soil organic carbon content.The highest contents of total chlorophyll in blueberry leaves were found in rabbit manure treatment.The soluble solid content of blueberry fruits showed a trend of bean cake>rabbit manure>sheep manure with significant differences among treatments.In summary,compared to sheep manure and bean cake fertilizer,the treatment of rabbit manure is more beneficial to the growth and production of blueberries.
