Description
Technical Field
The invention relates to the field of salt-tolerant plant planting in saline-alkali soil improvement, in particular to a method for improving the planting survival rate of NyPa pasture in coastal saline-alkali soil.
Background
The coastal saline-alkali soil in China has large area and wide distribution range, and is a key point and a difficult point for developing and utilizing forestry. Biological improvement, especially planting salt-tolerant plants, is a fundamental measure for comprehensively treating saline-alkali soil. Through biological measures, the ecological environment of the saline-alkali area can be improved, the further salinization of soil is inhibited, the effect of reducing the salt content of shallow soil is obvious, and remarkable economic benefit is generated. However, due to the limitations of low salt tolerance index, poor adaptability, low economic value of processing and utilization and the like, salt-tolerant plants with high ecological and economic values are difficult to popularize and apply in a large area in saline-alkali soil with more than moderate degree, especially in the production of improvement of severe saline-alkali soil, i.e. lack of economic salt-tolerant greening plant materials becomes a significant limiting factor for ecological construction and agricultural sustainable development of coastal saline-alkali soil.
Therefore, salt-tolerant NyPa pasture is introduced from the United states in 2002, is successfully introduced in China for the first time, fills the blank of salt-tolerant plants of halophytes in China, enriches germplasm resources of halophytes in China, and is a major breakthrough in introduction of salt-tolerant ecological economic plants in China. Compared comprehensively with the comprehensive stress resistance, economic utilization value and practical effect of popularization and application, no plant material of the same kind can be compared favorably with the plant material, and the plant material is an excellent ecological economic salt-tolerant plant in the world at present. NyPa pasture originates from intertidal zone and male plant, is a perennial, wide-salt and wide-temperature C4 plant, can only be bred through rhizome nutrition, adopts artificial division breeding in production, is a vigorous growth phase in the first 5 years after planting, declines later in growth, and does not have the possibility of external biological hazard when popularized in a large area. The compound fertilizer can resist 20-30 per mill of soil salt content, has comprehensive excellent resistance of coordinated and unified salt tolerance, drought tolerance and waterlogging tolerance, is an extremely excellent saline-alkali land pioneer plant and high-quality forage grass feed for treating coastal saline-alkali areas which suffer from spring drought, summer waterlogging and saline-alkali hazards all year round, and has great significance for agriculture and animal husbandry development and ecological engineering construction in the areas.
Experiments and production of the NyPa forage grass for improving the saline-alkali soil for years prove that although the NyPa forage grass can resist 20-30 per mill of soil salt content, the NyPa forage grass has a relatively sensitive stage to a high-salinity environment in the early stage of planting in the coastal severe saline-alkali soil (the salt content of a 0-20 cm soil layer is more than 6 per mill), the problem of low planting survival rate occurs, and once the plants are planted and survive, the plants have high salt resistance.
