摘要:
This report of a three-year study of the effects of lunar rhythms on the growth of radish supplements a companion report on rye (Spiess, 1990a). In 1979 and 1980, plantings with radish were carried out on a daily basis over a four-week period in April and May. In 1982, plantings were carried out every second day for an eight-week period from April to June. These field plantings were carried out on a biodynamic farm in randomized, complete-block designs with four replications per planting date. Leaves and roots were harvested when the same constellation in which planting took place had returned. Seeds were harvested when physiologically Nature. Curves fitted from polynomial regressions of yields against seeding dates were used to indicate general trends associated with the dominating primary growth factors such as weather. The magnitudes of effects associated with planting at a specific lunar position were measured by the deviations from the trend curve.
