摘　　要：Field studies were conducted in the Jiuwantan Forest Farm,Huadu District of Guangzhou City from June 2004 to March 2006 to evaluate the effects of planting spacings(0.5 m × 0.5 m,0.5 m × 1.0 m and 1.0 m × 1.0 m) and different fertilizers(bio-fermented manure,NPK compound fertilizer and NPK mixed fertilizer) on the growth of Daemonorops margaritae grown under irrigation and full-light conditions for edible shoots production.The effects of application of different fertilizers on the mean height,length of stems and number of leaves of 30-month old seedlings were not statistically significant,but the planting spacings were(P < 0.05).The two trial plantations became harvestable 18 months after planting when about one-third of seedlings produced new shoots.Results obtained from a sample harvest 20 months after planting showed that the average number of new shoots(suckers) per plant was 1.8,the average lengths of stems and edible shoots(palm hearts) were 45.3 cm and 18.8 cm,respectively.The average fresh weights of defoliated stems and edible shoots were 182.2 g and 14.9 g,respectively.These results suggest that the productivity in the first harvest is rather low.Field studies were conducted in the Jiuwantan Forest Farm,Huadu District of Guangzhou City from June 2004 to March 2006 to evaluate the effects of planting spacings(0.5 m × 0.5 m,0.5 m × 1.0 m and 1.0 m × 1.0 m) and different fertilizers(bio-fermented manure,NPK compound fertilizer and NPK mixed fertilizer) on the growth of Daemonorops margaritae grown under irrigation and full-light conditions for edible shoots production.The effects of application of different fertilizers on the mean height,length of stems and number of leaves of 30-month old seedlings were not statistically significant,but the planting spacings were(P < 0.05).The two trial plantations became harvestable 18 months after planting when about one-third of seedlings produced new shoots.Results obtained from a sample harvest 20 months after planting showed that the average number of new shoots(suckers) per plant was 1.8,the average lengths of stems and edible shoots(palm hearts) were 45.3 cm and 18.8 cm,respectively.The average fresh weights of defoliated stems and edible shoots were 182.2 g and 14.9 g,respectively.These results suggest that the productivity in the first harvest is rather low.
