摘要
为保护和开发白花丹参,完善其栽培理论,本研究设置5个不同施钾处理,对白花丹参进行人工栽培试验,测定其生长发育、产量、品质、养分利用情况。结果表明,钾肥与白花丹参产量关系密切,适当施用钾肥可促其生长。然而,随施钾量和产量的增加,钾素的利用率下降,根中有效成分含量也降低,但干物质和有效成分产量均比对照处理提高,白花丹参最适施钾量为253.6 kg/hm2。
In order to protect and utilize Salvia miltiorrhiza Bunge f.alba, and improve its cultivation techniques , 5 different potassium fertilizer treatments were set to study the effects on its growth and development, yield, quality and nutrient utilization .The results showed that potassium fertilizer had close relationships with yield of Salvia miltiorrhiza Bunge f.alba.Suitable rate of potassium fertilizer could promote its plant growth .However , with the increase of yield and application rate of potassium fertilizer , the potassium use rate and active components in root decreased , while the dry matter and output of active components increased compared with CK .The optimal application rate of potassium fertilizer for Salvia miltiorrhiza Bunge f . alba was 253 .6 kg/hm2 .
