Abstract:
ObjectiveTo investigate the effects of different phosphorus application rates on the growth， yield and quality of two-year-old Belamcanda chinensis and provide a basis for phosphorus application in the high-quality and high-yielding cultivation of B. chinensis. MethodIn this study， we designed five phosphorus application rates of 0 （P0）， 60 （P60）， 120 （P120）， 180 （P180） and 240 （P240） kg·hm-2 on the basis of 120 kg·hm-2 nitrogen and potassium fertilizers to investigate the effects of different phosphorus levels on the agronomic traits， yield， mineral content， flavonoid content and phosphorus utilization efficiency of B. chinensis through field experiments. ResultThe plant height and tillering number of B. chinensis gradually increased after phosphorus fertilization. The phosphorus application increased the rhizome yield by 37.59%-61.03% compared with P0 treatment and the highest yield was achieved when phosphorus fertilizer was applied at 120 kg·hm-2. The content of mangiferin and irisflorentin in the rhizomes gradually increased with the increase in phosphorus application and the moderate application of phosphorus fertilizer increased the content of tectoridin， iridin and irigenin. The highest Mn， Cu and Fe elements were achieved at 60 and 120 kg·hm-2 of phosphorus fertilization， respectively. The overall quality scores of B. chinensis were ranked in the order of P240>P180>P120>P60>P0. With the increase in phosphorus application， the phosphorus accumulation of B. chinensis first increased and then decreased， and the partial factor productivity， apparent utilization rate and agronomic efficiency of phosphorus fertilizer gradually decreased. ConclusionConsidering the yield， quality and phosphorus utilization efficiency of B. chinensis， it is recommended to apply phosphorus fertilizer at about 120 kg·hm-2 in the production of B. chinensis in Tuanfeng county.
