Study on High-yielding Cultivation Techniques of Acorus tatarinowii

A cultivation experiment on wild seedlings of Acorus tatarinowii was done by random block design with factors of density, basal dressing and top dressing. It was showed by the results that the growth of Acorus tatarinowii was significantly influenced by different technical measures. Comprehensively taking the growth condition, land-use efficiency and the economic yield into consideration, the appropriate combinations of high-yielding cultivation techniques for Acorus tatarinowii were: A₂B₁C₁, A₂B₁C₂, A₂B₂C₁ and A₂B₂C₂, respectively with the fresh weight yield per hectare as 9.52,7.96,8.78,8.32 t, and with dry weight yield as 2.64,2.22,2.44, 2.32 t per hectare respectively. Bumper harvest could be obtained if the spacing was 40 cm×40 cm, and 1 kg farmyard manure or ordinary super phosphate were used as basal dressing per m², and 20 g/m² or 50 g/m² of urea was applied every 60 d as top dressing in the growing period.
