不同覆盖物对裕丹参产量和质量的影响

Effect of Different Covering Materials on the Quality and Yield of Yu Salvia militiorrhiza

以裕丹参为试材,研究露地栽培、地膜覆盖、麦秸覆盖3个不同覆盖方式对裕丹参产量和有效成分(丹酚酸B、丹参酮ⅡA)的影响。结果表明:麦秸覆盖和地膜覆盖的丹参产量极显著高于露地栽培,且麦秸覆盖的产量高于地膜覆盖,但二者无显著差异;在有效成分含量上,10月份均以地膜覆盖最高。因此,塑料地膜覆盖最有利于丹参生长发育。

Taking Yu Salvia militiorrhiza as test materials, the effect of different covering treatments （open field cultivation, straw cultivation and plastic film cultivation） on the yield and effective components of Yu Salvia militiorrhiza was studied. The results showed that the yield was significantly higher under straw mulching or plastic film mulching than that of open field. The yield of straw mulching was higher than that of plastic film mulching, but there was no significant difference between them. The content of effective components were the highest all with plastie film mulching in October. The plastic film mulching was most beneficial to growth of Salvia miltiorrhiza.
