OBJECTIVE: Study on the growth development and fertilizer requirement regularity of Radix Hedysari.
METHODS: Adopted the field experiment, investigate the influence of Radix Hedysari by applying different amount of palygorskite and fertilization.
RESULTS: The growth process of plant height and branch height of Radix Hedysari were divided into two stages, the stage from emergence to late July was fast growth phase, and the stage from late July was slow growth stage. The dry matter accumulation center of Radix Hedysari transferred from aerial part to underground part in late July. Single application of palygorskite (1500 kg/hm2) and single application of palygorskite (2250 kg/hm2) increased plant height, promoted dry matter accumulation in aerial part and root of Radix Hedysari. Combined application of palygorskite (1500 kg/hm2) and NPK fertilizer and combined application of palygorskite (2250 kg/hm2) and NPK fertilizer improved growth indexes of Radix Hedysari compared with single application of NPK fertilize.
CONCLUSION: The yield of Radix Hedysari was improved by applying palygorskite and fertilization.
