【摘要】 为了探讨施基肥对广金钱草植株生长、产量及效益的影响。采用施用鸡粪和鸡粪加复合肥进行广金钱草种植试验。结果表明:施基肥的处理与对照相比,植株主茎平均多长6.2～21.3 cm、分枝多3.9～13.5条,药材产量每平方米增产最少为82.7 g,最多达422.4 g;以每平方米施鸡粪6 kg的处理效果最佳,植株主茎最长、分枝最多、产量最高,投入产出比最高(1∶5.28)。基肥能极大促进广金钱草植株生长和增加分枝,显著提高药材产量及效益。更多还原

【Abstract】 Field experiments were conducted to investigate the effects of basal fertilizer on the growth,yield and benefit of Desmodium styracifolium(Osbeck) Merr.plant by setting five treatments of chicken fertilizer,chicken fertilizer and compound fertilizer mixed,and no fertilizer for the controls.Results in apply basal fertilizer treatment compared with the control showed that the average length of the caulis of D.styracifolium(Osbeck) Merr.was more than 6.2-21.3 cm,branches were more than 3.9-13.5,the minimum yield of medicinal herbs of per square meter increased 82.7 g and the maximum increased 422.4 g.The treatment of applying chicken fertilizer for 6 kg per square meter manifested the best effect of the longest main stem height,the more branches and the highest yield,which showed obvious economic benefit with 1∶ 5.28 input-output ratio.It could be concluded that the basal fertilizer could promote the growth,increase the more branches,significantly improve the yield of D.styracifolium(Osbeck) Merr.plant.更多还原
