Description

A kind of song-Nen plain saline-alkaline the cultivation of Mongolia's Liu Yuji human assistance method
Technical field
The invention belongs to salt-soda soil field of planting.
Background technique
Song-Nen plain saline-alkaline soil is one of three dodium thiosulfate saline-alkali soil areal concentration of the world, wetland with saline-alkaline area about 327 Ten thousand hm2, the 21% of the Plain area is accounted for, is the maximum distribution of China's salinisation soil.In recent years, due to natural cause With the collective effect of human factor, salinization and alkalization is constantly deepened, and forms grassland salinization of soil, tilth salinization and Marsh Wetland salt Alkalization, increases wetland with saline-alkaline area year by year, and land use difficulty continues to increase, and has seriously affected holding for economy and environment Supervention exhibition.As land resource, salt-soda soil has become a part of important land resources.
Salinized soil is largely to be accumulated by soda and formed, and pH value reaches 8.0 or more, and nutrient content is lower, moisture Physical behavior is poor, does not have the condition of plant growth.The control measures of salinized soil can be divided into two major classes, Yi Leishi at present Abiology measure, one kind are biology measures, and biology measure is mainly improved with introducing a fine variety pionner or saline alkali tolerant plant Stinkgrass flower, chinampoensis, angle alkali in salinization soil, such as Suaeda are fluffy etc., mostly herbaceous plant.
Mongolian willow (Salix linearistipularis Hao) is Salicaceae, sallow, woody brush or little Qiao Wood, is distributed mainly on riverside, plain wetland and varieties in saline-alkali areas, light, cold-resistant, drought-enduring and resistance to water-wet, with stronger saline-alkali tolerant Characteristic can influence and improve the pH value of soil, be song-Nen plain saline-alkaline natural community distribution in unique xylophyta, can As song-Nen plain saline-alkaline the important species of revegetation.The sapling multiplication of Mongolia willow mainly uses the side of crop field cuttage at present Formula, which nursery need a large amount of -2 years 1 year raw Mongolian willow nutrition branches as cutting, and investment is big, at high cost, expend a large amount of Manpower and material resources.On the other hand, Mongolian willow mid-April blooms, and five the end of month seeds are mature, and seed amount is abundant, and seed longeivity 30 days Left and right when moisture abundance, can sprout rapidly with adopting with broadcasting.But semiarid region semi-moist, year are in due to song-Nen plain saline-alkaline Precipitation about 450mm, 70%~80% rainfall are distributed in 7~September part, and annual water surface evaporation is 1500mm~2000mm. Strong evaporation forms this area's spring, and seriously arid short of rain, late May, Mongolian willow seed maturation are difficult to sprout when landing naturally Hair, until seed short-lived when rainy season arrives loses vigor already, in the Mongolian willow seed natural renovation institute of salt-soda soil growth The shoot survival percent that grows directly from seeds formed is lower than 10%.
It follows that the sapling multiplication of existing Mongolia willow is put into greatly by the way of the cuttage of crop field, and it is at high cost, it expends a large amount of Manpower and material resources, fallen naturally using seed is mature, when the problem of being difficult sprouting.
Summary of the invention
