不同种植密度和施肥处理对尾巨桉和油茶林下百部生长及产量的影响
Effects of Different Cultivation Densities and Fertilization Treatments on the Growth and Yield of Stemona japonica under Eucalyptus grandis ×E.urophylla and Camellia oleif era Forests
摘要
Abstract
In order to investigate the effects of different planting densities and fertilization treatments of Stemona japonica in Eucalyptus grandis × E.urophylla and Camellia oleifera forest.Different planting densities(300～1 500 plants/667 m2)of S.japonica were set under 3-year-old Eucalyp-tus grandis×E.urophylla forest and 0.5-year-old Camellia oleifera forest,and different fertiliza-tion treatments were applied under 1 200 plants/667 m2 density forests.The results showed that:(1)Regarding planting density test,moderate dense planting could promote the growth and fresh weight of S.japonica.With the increase of planting density,the survival rate of,fresh weight of single tu-ber and tuber yield increased of S.japonica first and then decreased,and fresh weight of underground part per plant gradually decreased,while the number of tuber per plant increased first and then de-creased under Eucalyptus grandis×E.urophylla forest,and showed an overall upward trend under(C.oleifera)forest;(2)Regarding fertilization test,most indexes of S.japonica were significantly better than that of the control.3 kg/plant bio-organic fertilizer treatment could increase the tubers number of S.japonica under Eucalyptus grandis ×E.urophylla forest,while the remaining indica-tors were the highest under 3 kg/plant organic and inorganic compound fertilizer treatment.The effect of organic and inorganic compound fertilizer is better than that of organic fertilizer with the same ferti-lization amount,and the growth and yield of S.japonica under C.oleifera forest were higher than that under Eucalyptus grandis×E.urophylla forest in the two experiments.In summary,the plant-ing density of 1200 plants/667 m2under the two kinds of forests were the best(the yield of tuber were 4 908.11 and 5 959.37 kg/667 m2),the yield was the highest,and the application of 3 kg/plant or-ganic and inorganic compound fertilizer under this planting density could best promote the growth and yield of S.japonica(the yield of tuber were 5 521.64 and 6 116.04 kg/667 m2).It provide the refer-ence for the forest-medicine model of S.japonica.关键词
