摘要
目的研究密度、磷、氮对穿心莲产量和质量的影响。方法田间随机区组设计,高效液相色谱法测定穿心莲内酯和脱水穿心莲内酯量。结果密度对穿心莲的株高、鲜质量、干质量、脱水穿心莲内酯的量有极显著影响;磷肥对穿心莲内酯量、脱水穿心莲内酯的量、内酯总量等质量性状及经济产量有极显著影响;氮肥对穿心莲的干质量、穿心莲内酯的量、脱水穿心莲内酯的量、内酯总量的经济产量有显著或极显著影响;磷肥,磷、氮互作对经济产量影响较大;鲜质量与干质量间相关极显著;质量性状间、质量性状与经济产量间相关显著或极显著。结论密度1.8×105株/hm2、PO540kg/hm2、纯氮225kg/hm2经济产量最高。
Objective To study the effects of density, phosphorous （P）, and nitrogen （N） fertilizers on yield and quality of Andrographis paniculata. Methods Randomized block design in yield was used and HPLC was used to analyze the content of andrographolide and dehydroandrographolide. Results Plant height, fresh weight, dry weight, content of dehydroandrographolide were influenced significantly by density. The quality character and economic yield of content of andrographolide, dehydroandrographolide, total content of both andrographolide and dehydroandrographolide were significantly influenced by P nutrition. The economic yield of dry weight, content of andrographolide and dehydroandrographolide, and total content of both andrographolide and dehydroandrographolide were influenced significantly or extreme significantly by N nutrition. P and the interaction of P and N fertilizer extremely influenced the economic yield. The relative influences between plant weight and dry weight was extremely significance, that between quality character and quality character, that between quality character and economic yield were significant or extremely significant. Conclusion When planted with 1.8×10^5/hm^2, fertilizered with P2O5 540 kg/hm^2 and pure N225 kg/hm^2, the hightest economic yield is gained.
