The invention discloses a method for improving a seashore salinized land by using seashore paspalum. The method for improving the seashore salinized land by using the seashore paspalum comprises the following steps that step 1, firstly seeds are prepared; step 2, the seeds are sown; step 3, mowing is carried out after the lawn is formed; and step 4, crops are planted. The sowing conditions before the seeds are sown in the step 2 comprise sowing time, soil treatment, a sowing mode and measures after sowing. According to the method for improving the seashore salinized land by using the seashore paspalum, salt and alkali in soil can be gradually eliminated, and the purpose of radically and thoroughly treating the salinized land is achieved; and the seashore paspalum is resistant to salt and alkali, resistant to drought, high in adaptability and vigorous in vitality, can survive and grow under various conditions, belongs to perennial plants, can be continuously harvested for many years after being planted once, does not need to be managed after being planted and does not need to be watered and fertilized, so that a large amount of manpower and material resources are saved, and the seashore paspalum is high in salt absorption capacity and wide in adaptability.
Description
technical field [0001] The invention relates to the technical field of seashore saline land improvement, in particular to a method for seashore paspalum to improve seashore saline land. Background technique [0002] The occurrence of saline soil in coastal areas is the result of the impact of sea water. There are two ways for seawater to affect soil salt accumulation. This situation mainly occurs when the coastal area is still in the early stage of underwater accumulation. Salt. Its characteristics are firstly that the salt composition is single, and chloride is the absolute dominant, and secondly, the cross-section contains salt, and the surface accumulation of salt is still poor. South China includes Guangdong, Guangxi, Hainan, Hong Kong, Macao and Taiwan, and the South China Sea Islands. The coastline is long, the phreatic water level in the coastal area is shallow, the mineralization is high, the surface is easily returned to salt, and the ecosystem is fragile. In rec...
