减磷对黄芪生长与产量品质的影响
Effect of Phosphorus Reduction on Growth,Yield and Quality of Astragalus membranaceus
摘要
Abstract
The effects of phosphorus reduction on the growth,physiology,yield and quality of Astragalus membranaceus were studied to provide scientific basis for its fertilization and cultivation.The growth,physiology,yield and quality indexes were measured by setting 4 phosphorus application levels.Results showed that phosphorus reduction by 25%treatment(P2)had a significant effect on growth,yield and quality of A.membranaceus.The seedling emergence rate,leaf area,root length,root diameter,fresh biomass,dry biomass,carotenoids content,SOD activity,POD activity,CAT activity,economic benefit and glucosinolate of acacia catechu content exhibited significantly increased by 6.76%,3.32%,6.76%,18.01%,2.13%,3.80%,26.00%,7.12%,12.04%,3.90%,10.72%and 13.47%respectively,compared to the full phosphorus application treatment.There were no significant differences in stem diameter,fresh yield,dry yield,drying rate,first grade rate,total ash and contents of chlorophyll a,chlorophyll b,extract,polysaccharide and astragaloside,compared with full phosphorus application.关键词
