不同替代程度对葎草控制喜旱莲子草光合作用的影响
Effects of Replacement Control with Humulus scandens on Photosynthesis of the Invasive Plant Alternanthera philoxeroides
摘要
Abstract
In order to better explain the mechanism of the replacement control to invasive plant, the effects of the native plant Humulus scandens (Lour.) Merr.on the photosynthesis of the invasive plant Alternanthera philoxeroides (Mart.) Griseb.were studied with the different replacement degrees.Four treatments were setted, 3∶3, 2∶4, 4∶2, 6∶0 and 0∶6 were planted in 4 proportions.The results showed that the net photosynthetic rate of 4∶2 treatment was single peak, and the net photosynthetic rate was lower in one day, and the other treatments were double peaks in the middle of August 2017.In June 2017, August and October, the net photosynthetic rate of 4∶2 treatment was one peak, and the maximum peak appeared at 10∶00, then gradually decreased.The maximal net photosynthetic rate and daily net photosynthetic rate of the 4∶2 treatment were both higer than other treatment June, which was significantly lower than that in August and October.The chlorophyll content of the lotus grass was measured.In the June 2∶4 treatment, the chlorophyll content of Alternanthera philoxeroides was significantly lower than the other treatments.In August and October, the differences of chlorophyll content were not significant.关键词
