木通引种栽培土宜分析

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／kg，平均为45.3g／kg；全氮含量为0．64～3．10g／kg，平均为1．95g／kg；速效氮含量为7．19～140．55mg／kg，平均为77．59mg／kg；速效磷含量为5．57～16．00mg／kg，平均为10．15mg／kg；速效钾含量为5．56～47．54mg／kg，平均为31．95mg／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。

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

The study was conducted in the Akebia quinata decne producing area in Hunan and Hubei provinces.A series of methods,which contained air-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 1.95 g/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 of Akebia quinata decne.
