Abstract:
ObjectiveTo investigate the effect of the combined application of organic fertilizer and chemical fertilizer at different ratios on the growth， yield and quality of two-year-old Belamcanda chinensis and provide a scientific basis for fertilization to achieve high yield and quality of this medicinal plant. MethodIn a field plot experiment， we designed five fertilization patterns with organic fertilizer and chemical fertilizer at different ratios： OM0 （pure chemical fertilizer）， OM1 （30% organic fertilizer + chemical fertilizer， application of organic fertilizer at 2 567 kg·hm-2）， OM2 （50% organic fertilizer + chemical fertilizer， application of organic fertilizer at 4 283 kg·hm-2）， OM3 （70% organic fertilizer + chemical fertilizer， application of organic fertilizer at 6 000 kg·hm-2）， and OM4 （pure organic fertilizer， 8 567 kg·hm-2）. The effect of different fertilization patterns on the agronomic properties， herb yield， flavonoid content， mineral element content， and fertilizer utilization rate of B. chinensis were determined. ResultThe combined application of organic fertilizer and chemical fertilizer at an appropriate ratio increased the leaf width and promoted tillering， thereby improving the yield of B. chinensis. The yield of OM1 and OM2 groups increased by 6.65% and 13.10%， respectively， compared with that of OM0 group， while too high a proportion of organic fertilizer led to a decrease in yield. With organic fertilizer application， the content of mangiferin， tectoridin， iridin， tectorigenin， irigenin， and irisflorentin in the rhizomes of B. chinensis increased. Moreover， a certain proportion of organic fertilizer facilitated the accumulation of functional elements such as K， Fe and Cu. The results of the principal component analysis showed that the overall quality of B. chinensis was ranked in the order of OM3 > OM2 > OM1 > OM4 > OM0. The OM2 group had the maximum accumulation of N， P and K and the maximum partial factor productivity of fertilizer. ConclusionAccording to the agronomic traits， yield， quality indexes and fertilizer utilization rate of B. chinensis under different fertilization patterns， we recommended to apply 4 283 kg·hm-2 organic fertilizer in combination with chemical fertilizer to the production of two-year-old B. chinensis， so as to improve the quality and yield of B. chinensis.
