Preliminary Study on Soil Applicability Analyse of Introducing Variety Planting with the Akebia quinata decne

对采自湖南、湖北两省木通产地的28个土壤样品进行风干、弃去杂物、磨细以及过筛处理,分别测定28个土样的pH值、有机质、全氮、碱解氮、速效磷以及速效钾含量等6项农化指标.结果表明:木通产地土壤pH值为4.89～6.62,平均为5.63;有机质含量为5.2～85.6g/g,平均为45.3 g/kg;全氮含量为0.64～3.10 g/kg,平均为1.95 g/kg;速效氮含量为7.19～140.55 mg/kg,平均为77.59 mg/kg;速效磷含量为5.57～16.00 mg/kg,平均为10.15mg/kg;速效钾含量为5.56～47.54 mg/kg,平均为31.95 mg/kg.因此,可以初步确定,养分含量比较丰富的酸性土壤适合木通生长.

The study was conducted in the Akebia quinata decne producing area in Hunan and Hubei provinces. A series of methods, which contained alr-drying, abandoning miscellaneous objects, whetting thin and filtering by sifter, was used distinguishingly to 28 soil samples collected in the mentioned area. After that, the 28 soil samples were measured by 6 agricultural chemical indices, that is, the soil pH, the organic matter content, the total N, the alkali hydrolysable N, the available P and the available K. The results showed that the soil pH was between 4.89～6.62, the average of which was 5.63, the organic matter content was 5.2～85.6 g/kg, the average was 45.3 g/kg, the content of total N was 0.64～3.10 g/kg, the average was 1.95g/kg, the content of available N was 7.19～140.55 mg/kg, the average was 77.59 mg/kg, the content of available P was 5.57～16.00 mg/kg, the average was 10.15 mg/kg, the content of available K was 5.56～47.54 mg/kg, the average was 31.95 mg/kg. Therefore, we could generally make sure that the acidic soil with aboundant nutrient content was suitable for the growth ofAkebia quinata decne.
