Growth status of invasive plant Alternanthera philoxeroides after adding earthworms
Because the chemical substances in the invasive organisms themselves affected soil animals and soil processes,this experi-ment used earthworms,a common soil animal,and Alternanthera philoxeroides(Mart.)Griseb.,an important invasive plant,as mate-rials to study the effects of earthworms on physiological and biochemical indexes and growth of A.philoxeroides.The results showed that the content of chlorophyll a,chlorophyll b,carotenoid and total chlorophyll in leaves of A.philoxeroides increased with the increase of of the number of earthworms.The contents of starch and non-structural carbohydrate(NSC)in the leaves of A.philoxeroides increased with the increase of the number of earthworms.With the increase of the number of earthworms,the mass per unit area and tiller num-ber of A.philoxeroides showed an upward trend.It could be seen that soil animals earthworms were beneficial to the growth of the inva-sive plant A.philoxeroides.
