针对延边州珲春市苹果梨园土壤,在苹果梨园内布置剖面点,挖掘剖面,根据土壤形态划分土壤自然发生层,分层采集土壤样品,采用改进Bowman-Cole法测定了土壤中不同土层各种形态的有机磷含量。结果表明:在珲春苹果梨园地区,各剖面层次荒地有机磷总量均高于苹果梨园;随土层深度增加,有机磷各组分含量整体呈下降趋势;有机磷各组分中,活性有机磷表现更易于植物吸收;有机磷各组分占有机磷总量的比例不尽相同,其共同之处表现为中活性有机磷组分在有机磷总量中占有较高的比例,中活性有机磷为珲春苹果梨园土壤中重要的有机磷形态。
Aiming at the apple pear orchard soil in Hunchun, Yanbian, the profile points were excavated in apple orchard, the profiles were excavated, the soil natural strata were divided according to soil morphology, and the soil samples were stratified and collected. The Bowman-Cole method was used to determine the contents of various soil layers Form of organic phosphorus content. The results showed that in the apple orchard area of Hunchun, the total amount of organic phosphorus in the wasteland was higher than that of the apple orchards at each level. With the depth of the soil layer increasing, the content of organic phosphorus decreased overall. Among the components of organic phosphorus, The performance of more easily absorbed by plants; organic phosphorus components of the total proportion of organic phosphorus are not the same, the common part of the active organic phosphorus components in the total organic phosphorus occupy a higher proportion of active organic phosphorus Hunchun apple pear orchard soil organic phosphorus form.
