  • Effect of Palygorskite Adding NPK Fertilizer on Plant Dry Matter Accumulation and Polysaccharide Content of Radix Hedysari

    [Objective] This research was to study the effect of palygorskite adding NPK fertilizer on plant dry matter accumulation and polysaccharide content of Radix Hedysari,providing a scientific basis for the rational fertilization of Radix Hedysari.[Method] Plant dry matter accumulation of Radix Hedysari of growth period in each sample was determined;the yields after post-harvest were calculated;the polysaccharide content of Radix Hedysari was determined with phenol-sulfuric acid method and the polysaccharide yields were calculated.[Result] Palygorskite and NPK fertilizer can promote the dry matter accumulation and the HPS content of the underground sections at the latter period (the latter September and the end October) of Radix Hedysari,or slow down the reduction of polysaccharide content and improve the quality of Radix Hedysari;and can significantly increase the yield of Radix Hedysari and polysaccharide.The high-volume palygorskite(2 250 kg/hm2) and NPK fertilizers can significantly increase the yield of Radix Hedysari and polysaccharide,to 731.32 kg/hm2.The single application of Palygorskite can promote the amount of dry matter accumulation and the polysaccharide content of various parts of Radix Hedysari,and slow down the reduction of polysaccharide content of underground parts and promote the yield of Radix Hedysari and polysaccharide.The effect of high-volume palygorskite(2 250 kg/hm2) and NPK fertilizers was obvious,increasing to 368.34 kg/hm2.[Conclusions] Palygorskite and NPK fertilizer can increase the use of NPK fertilizer and significantly increase the yield and quality of R.Hedysari,the effect of the high-volume palygorskite(2 250 kg/hm2) and NPK fertilizer was obvious.The single application of palygorskite had the effect of extending the period of dry matter accumulation and delaying the polysaccharide content reduction.
