研究施用秸秆堆肥对老参地土壤理化性状的影响.以白浆土为供试土壤,采用田间试验法,研究秸秆堆肥不同施用量对土壤理化性状的调控作用.施用秸秆堆肥可以显著提高土壤有机质、碱解氮、有效磷和速效钾含量,不同处理土壤有机质含量分别增加了5.2％、7.6％和10.1％,土壤代换量、代换性盐基、盐基饱和度与秸秆堆肥用量呈显著的正相关趋势;施用秸秆堆肥后,土壤容重显著降低,二者间呈极显著的负相关趋势,总孔度和含水量显著增加,土壤中＞ 0.25mm的水稳性团粒总量明显增加;人参产量极显著增加,趋势表现为S15＞S10＞S5.施用秸秆堆肥能够改善土壤理化性状,提高土壤供肥性能,增加人参产量.%To study the impact of straw compost on soil physical and chemical properties of Cultivated Ginseng Soil. Method: Albic soil as tested soil, a field experiment was conducted to study the regulatory role of the straw compost application rate on soil fertility.The results showed that straw compost significantly increased soil organic matter, nitrogen, available phosphorus and available potassium, organic matter content increased by 5.2% ,7.6% and 10.1%,the exchange capacity, exchangeable base,base saturation degree was a significant positive correlation trend with the straw compost dosage; After the application of straw compost,soil bulk density was significantly decreased, and was very significantly negative related trend with the straw compost dosage, total porosity and water content was significantly increased, the amount of water stable aggregate( > 0.25mm)was increased significantly; ginseng production was significantly increased, the trend is exhibited in S15 > Sjo > S5. Application of straw compost can improve soil physical and chemical properties, improve the performance of the soil for fertilizer, increase production of ginseng.
