Abstract:In order to understand the planting patterns on the growth of Morinda officinalis, its growth status was studied under two planting patterns in Gaoliang Town, Zhaoqing City, Guangdong. The results showed that the contents of available mineral nutrients and organic matter in soil of sloping land continguous planting base (PLZ) were lower than those of slope surrounded by forest planting base (PWZ) by 24%-28% and 38%-43% (P<0.01), respectively. The morphological indexes of stem, leaf and fleshy root of M. officinalis in PWZ were significantly better than those in PLZ (P<0.01) after planting for 3 years. However, with the extension of cultivation time, the growth of fleshy roots in PLZ was better than that in PWZ. The yield of 6-year-old M. officinalis in PLZ was 1.16-1.17 times higher than that in PWZ. The contents of polysaccharides, total flavonoids and proantho-cyanidins of M. officinalis in PLZ were significantly higher than those in PWZ (P<0.01), and the contents of effective components increased along the cultivation years. Therefore, it was suggested that the fleshy root quality of M. officinalis was good under PLZ pattern, which as medicine was more in line with the requirements of national pharmacopoeia. At the same time, the planting base surrounded by cinnamon forest should reasonably increase the illumination and inhibit rattan growth of M. officinalis, so as to increase the yield of fleshy roots and accumulation of effective ingredients.
