摘要：凹凸棒石(attapulgite,ATP)作为肥料缓释剂和土壤改良剂在提高肥料利用率和提升农产品和中药材产量和品质方面已显示出显著成效。为探究ATP对当归Angelica sinensis生长及药材品质的影响,以“岷归1号”为研究对象,通过道地产区盆栽(土培)实验,比较分析常规化肥添加ATP对当归生长发育过程中植株生长形态、光合作用、土壤呼吸、根部阿魏酸和挥发油含量的影响,并从源-库关系探讨可能机制。结果显示ATP的肥料缓释效应可提供当归生长根系膨大期对营养元素的需要,提高叶片净光合速率,提高植株地上部分生物量,并促使根干物质积累期营养提前从地上部分(源)向地下根部(库)转移和积累,从而提高药材单株质量。ATP能够提高当归药材主要药效成分总阿魏酸(阿魏酸和阿魏酸松柏酯之和)的含量,其机制可能是促进根部阿魏酸的合成和向阿魏酸松柏酯的转化,但其对挥发油含量影响不大。ATP对土壤呼吸有一定的影响,但需要从根系活力、根际微生物和土壤微生物进一步研究。该研究可为当归田土壤修复、改良和当归生态种植提供一定的应用基础。
Attapulgite(ATP),as a fertilizer slow-release agent and soil conditioner,has shown remarkable effect in improving the utilization rate of fertilizer and the yield and quality of agricultural products and Chinese medicinal materials.This study aims to explore the effect of ATP on the growth and root quality of Angelica sinensis.To be specific,Mingui 1 was used,and through the pot(soil culture)experiment in the Dao-di producing area,the effects of conventional chemical fertilizer added with ATP on the morphology,photosynthesis,soil respiration,and content of ferulic acid and volatile oil in roots of Mingui 1 were detected.The underlying mechanism was discussed from the perspective of source-sink relationship.The results showed that ATP,via the fertilizer slow-release effect,could meet the needs of A.sinensis for nutrients at the root expansion stage,improve the net photosynthetic rate of leaves and aboveground biomass of plants,and promote the transfer and accumulation of nutrients from the aboveground part(source)to the underground root(sink)in advance during the dry matter accumulation period of roots,so as to improve the root weight per plant.ATP can increase the content of total ferulic acid(the sum of free ferulic acid and coniferyl ferulate),the main effective component of Angelicae Sinensis Radix,by promoting the synthesis of ferulic acid in the roots and the transformation to coniferyl ferulate.However,it had little effect on the content of volatile oil.ATP had certain influence on soil respiration,which needs to be further explored from root activity,rhizosphere microorganisms,and soil microorganisms.This study can lay a basis for soil remediation and improvement and ecological cultivation of A.sinensis.
