借鉴农业中地膜垄式栽培模式,研究耕作模式变化对白花丹参适宜种植区连作土壤环境的影响。利用土壤多参数测定仪对土壤各理化性质进行测定。结果:地膜垄式栽培相对于传统栽培,更能保持土壤温度稳定,耕作模式改变后土壤p H值由6.85上升为6.95,但有机质含量由0.69%下降为0.63%;不同土层深度土壤中铵态氮、速效钾、速效磷的含量有明显差别,其中0~10cm土壤中的含量相对较高;新的栽培模式下土壤中的磷酸酶活性低于传统栽培,整个生育期的平均值降低3.8%,蔗糖酶变化不明显。地膜垄式栽培有利于保持土壤温度的稳定,提高土壤p H值、磷酸酶和蔗糖酶的活性,促进白花丹参生长,一定程度上削减了连作障碍的产生。
Draw lessons from the film ridge cultivation mode in agriculture, and study the effect of tillage pattern on continuous cropping soil Salvia miltiorrhiza plantation soil environment. Soil physical and chemical properties were determined by soil multi - parameter measuring instrument. Results: Compared with the traditional cultivation, the plastic ridge cultivation could keep the soil temperature stable. The p H value of the soil increased from 6.85 to 6.95 after the farming mode was changed, but the organic matter content decreased from 0.69% to 0.63% The content of nitrogen, available potassium and available phosphorus were significantly different, among which, the content of 0-10 cm soil was relatively high. The activity of phosphatase in soil was lower than that of traditional cultivation under the new cultivation mode, and the average value of the whole growth period decreased by 3.8 %, Sucrase did not change significantly. The cultivation of plastic ridge is conducive to maintaining the stability of soil temperature, increasing soil p H, phosphatase and invertase activity, promoting the growth of Salvia miltiorrhiza, and reducing the continuous cropping obstacle to a certain extent.
