Method of utilizing semen cuscutae and humulus japonicus to jointly control alternanthera philoxeroides

Abstract

The invention belongs to the technical field of environment and ecology, and particularly relates to a method of utilizing semen cuscutae and humulus japonicus to jointly control growth and propagation of alternanthera philoxeroides. The method includes steps: selecting a field intruded by or prone to being intruded by alternanthera philoxeroides as a test field, ploughing, and leveling; selectingsemen cuscutae, humulus japonicus and alternanthera philoxeroides seedlings; transplanting the seedlings, and planting in a mixed manner according to a ratio of number of semen cuscutae, humulus japonicus and alternanthera philoxeroides plants of (1-3):(1-3):1 in each square meter; regularly watering and fertilizing the plants which are grown in a mixed manner; after the plants grow up, harvesting semen cuscutae and humulus japonicus; after harvesting, ploughing land again, picking out rhizomes of alternanthera philoxeroides deeply buried in a soil layer, and exposing to the sun. By the method, occurrence density of alternanthera philoxeroides can be lowered effectively, and growth and propagation of alternanthera philoxeroides can be inhibited. The method is simple and easy to implementand easy in popularization, and two plants of semen cuscutae and humulus japonicus have medicinal value.

Description

technical field [0001] The invention belongs to the technical field of environment and ecology, and in particular relates to a method for jointly controlling the lotus philodendron by using dodder and humulus. Background technique [0002] At present, biological invasion, habitat loss and global change are regarded as the three most difficult ecological and environmental problems in the world, ranking second only to habitat loss in severity, and may soon rise to the first place. Alien plant invasion is one of the most important aspects of biological invasion, which poses a huge threat to global and regional biodiversity and ecosystems. [0003] Lianzia philodendron, also known as water peanut, hollow lotus, and revolutionary grass, is a perennial amphibious plant. It is a malignant weed with strong invasive ability. It has the characteristics of strong reproductive ability, strong adaptability, and strong stress resistance. In the invaded area, the grass spreads naturally, ...
