Abstract

The nutrient competitive relationship between the seedlings of S.apetala and S.alterniflora were studied by the separation-planted method.The results showed that the competition had stimulated the height,diameter,crown width,number of branches,and leaf number of S.apetala,but inhibited its leaf area.The ground competition increased the aboveground biomass of S.apetala,but had little effect on the shoot ratio.The underground competition increased the aboveground biomass of S.alterniflora,but reduced its root biomass,and resulted in a minimum shoot radio.Underground competition promoted the main root growth of S.apetala, and inhibited the lateral root growth,but the ground competition was opposite;with the increased competition,root activity was decreased.The root activity of S.alterniflora was significantly decreased in underground competition.Both of chlorophyll a and b of the two species were reduced in ground competition.Under all competitive conditions,the content of P,K,Ca and Mg had no significant change,but the content of N was significantly reduced in ground competition of the two species.The competitive intensity of S.alterniflora was slightly higher than that of S.apetala,but the ground competition intensity of S.apetala was much higher than that of S.alterniflora,and the underground competition intensity of S.alterniflora and S.apetala had little difference.
