Description
Technical Field
The invention relates to the technical field of weed control, in particular to a method for replacing and controlling tropical coral island harmful plants by using native herbaceous plants.
Background
Each island in south China is composed of broken sand formed by coral and conchiolin residues, the naturally formed island is rich in calcium and phosphorus, island soil is mainly made of coral sand, is barren and poor in water retention, lacks real soil and fertility, and the island is high in sea wind on the island, high in pH value (pH 8.7-pH 10) of coral sand soil, high in salt fog and illumination radiation, strong in evaporation, long in drought season and particularly drought. Under the habitat condition, the method is only suitable for the settlement and growth of plant species with high temperature resistance, salt and alkali resistance, salt fog resistance and drought resistance.
Due to propagation factors such as human beings, vehicles, greening seedlings, foreign soil and the like, weeds such as the grass (Tridax procumbens), the Euphorbia hirta (Euphoria hirta), the grass (Euphorbia hypericifolia) and the like are brought into the south sea island, so that grass, such as fine leaf zoysia, the bermuda grass and the like, are paved on the lawns and the open lands in the sparse vegetation, and the free lands and bare lands of the grass, such as the grass, the grass (Chromolaena odorata) and the like grow, the grass plants are rapidly spread and have high vitality, the ecological place of the original vegetation or the artificial vegetation is preempted, such as the grass, the bermuda grass and the like, due to the fact that the grass is easily degraded, the grass is rapidly occupied, and the grass is seriously affected, once the grass is colonized, a large amount of manpower is required to be used for pulling out or selective chemical herbicide control is required, and when the chemical herbicide is selected, the grass is easy to control the island, the special environment is polluted, the herbicide is easy to use, and the effect of water source is hard to be expected, and the effect of environmental pollution is especially hard to be achieved. Therefore, from the aspect of searching for proper species and improving the site conditions of coral sand, namely water retention and fertilizer retention, the matrix formula for water retention and fertilizer retention is broken through, and an ecological friendly control method which is economical, easy to operate, free from environmental pollution and capable of effectively controlling weeds such as the aster, the euphorbia hirta and the milk-passing grass is integrated.
Through field investigation and observation, the situation that the sand beach grass tha profunda is grown (also called Lei Cao) is found, weeds such as the parthenote, the aspen and the martensi are seldom found to grow, the sand beach grass has the characteristics of salt resistance, alkali resistance, drought resistance and barren resistance, the sand beach grass is found to grow rapidly through experiments, the sand beach grass can form a lawn on coral sand in a short time and form a compact lawn layer, and even if the sand beach grass, the parthenote and the martensi are grown beside, the seeds of the parthenote can be effectively prevented from sprouting and growing on the lawn, so that the purposes of controlling the growth of the parthenote, the parthenote and the martensi are achieved. Meanwhile, the roots and creeping on the stems of the seashore grass are good, the resistance is strong, the plant diseases and insect pests are few, the smoothness of the built lawn is good, and less maintenance such as fertilization and pruning is not needed for a long time. Meanwhile, coral sand is free of water and fertilizer, drought and water shortage are easy, especially in dry seasons, plant growth is seriously affected, and therefore, how to effectively utilize the herba polygoni multiflori to control harmful plants in coral sand islands is a problem to be solved by the technicians in the field.
