摘要(Abstract):

该研究在兰州、巴彦淖尔、赤峰、酒泉等4个试验地进行,以甘草一年生移栽苗为繁殖材料,各试验地施肥处理相同,施肥处理采用"3414"完全随机区组试验设计。采收期取样,通过测量其鲜重、活性成分含量,考察各产地不同氮(N)、磷(P)、钾(K)配施对甘草产量及活性成分的影响,并与试验地土壤中N,P,K元素含量进行综合分析。结果表明:兰州、巴彦淖尔、赤峰、酒泉的甘草最佳氮磷钾配施分别为N1P2K1,N2P2K1,N1P1K2,N2P1K2,单种肥料对甘草产量的影响均呈抛物线型,氮磷钾配施对甘草活性成分含量无显著影响。综合试验地土壤中N,P,K含量分析可知,就N,P而言,土壤中速效元素含量低的元素种类即为限制该地产量增长的肥料种类;氮肥磷肥最佳用量与土壤硝态N、速效P元素含量呈反比;土壤速效P含量较低时,N肥、K肥对P肥表现出正交互效应,反之,则表现出负交互效应。
With annual Glycyrrhiza uralensis seedlings as experimental material,using"3414"optimal regression design and applied fertilizer,through the sampling of G. uralensis at harvest,root fresh weight and content of active components were measured in Lanzhou,Bayan Nur city,Chifeng,Jiuquan. Combined with NPK content in soil,potted experiments were used to study the effects of different nitrogen and phosphorus ratios on the dry matter accumulation and accumulation of active components of G. uralensis. The results reported as follows: the optimum fertilizer treatment in Lanzhou,Bayan Nur city,Chifeng,Jiuquan was N1 P2 K1,N2 P2 K1,N1 P1 K2 and N2 P1 K2,respectively. The efforts of single fertilizer on the fresh root weight acted as parabolic type. There was no significant effect of fertilizer treatment on the accumulation of active components of G. uralensis. Furthermore,in terms of nitrogen and phosphorus,the type of fertilizers that restricted the growth of the region was the type of elements with lower content in the soil. The optimal fertilizer usage was in inverse proportion to content of elements in soil. When the content of phosphorus in soil was low,nitrogen fertilizer and potash fertilizer showed positive interaction with phosphorus fertilizer,whereas,they showed negative interaction.
