Abstract
The invention belongs to the revegetation field, and in particular relates to a method for restoring bald spots of saline-alkali wetlands in alpine lakesides. The method comprises the following steps of: 1, making ridges on the surface of a boundary in a bald spot governance zone; 2, adding 5-10 cm alien soil in the bald spot governance zone; 3, reseeding forage grass in the bald spot governance zone; and 4, laminating and performing heat preservation in the bald spot governance zone. The method can be used for solving the problems that high saline-alkali degree of the bald spots in meadows of the alpine lakeside zones hinders the seeds of the reseeded forage grass from germinating and the forage grass is under an alpine and low-temperature condition in a preliminary state, so that the temperature of a bald spot restoring zone is increased by 1-3 DEG C; the number of the seedling emergence is more than 7000 per square meter, which is similar to the rate of the seedling emergence of the forage grass which is planted in farmland soil; the coverage is increased by 3-5 times to 50 %; the saline-alkali degree is reduced by 20 %; the moisture retention rate is increased by 10 %; the aboveground biomass is increased by 10 times; and the yield of the forage grass in the same year is up to 38.5 kg per mu so as to achieve the purpose of restoring the bald spots of the saline-alkali wetlands in the alpine lakesides finally.
Description
One, affiliated technical field
The invention belongs to the revegetation field, particularly a kind of high and cold lakeside saline-alkali wetland bald spot restorative procedure.
Two, background technology
At present, the technology for recovering vegetation on wetland degeneration grassland, high and cold lakeside only limits to come the restore vegetation situation by machinery or artificial after-culture, this kind technology is comparatively effective for the grassland that the original vegetation of non-saline and alkaline type and grassland reaches between 20-60%, and, natural vegetation higher for salinization and alkalization is less than the improvement in 10% bald spot district, the technology that after-culture is administered almost has no effect, causes this result's main cause to be successively: 1. the saline alkali in saline and alkaline bald spot district hinders the growth of can't emerging of after-culture grass seed; 2. saturated salt buck and high and cold low temperature suppress the after-culture growth jointly.
Three, summary of the invention
The present situation that has major defect at high and cold lakeside area grassland bald spot after-culture improvement technology distributed more widely and that continue to use at present, the present invention from anti-saline and alkaline, heat aspect such as cold-resistant and proposed a kind of high and cold lakeside saline-alkali wetland bald spot restorative procedure, to overcome the deficiency of present technology, lakeside saline-alkali wetland bald spot reparation is brought about tangible results, and biological synthesis values such as vegetation coverage obtain larger proportion and improve.The technical scheme that the present invention intends taking is: a kind of high and cold lakeside saline-alkali wetland bald spot restorative procedure, it is characterized in that forming by following step, 1, bald spot is administered the district's face of land, border making ridge, 2, bald spot is administered and is added 5-10 centimetre of soil moved in to improve the original in the district, 3, bald spot is administered after-culture herbage in the district, and 4, bald spot administers overlay film insulation in the district.Bald spot is administered the district's face of land, border making ridge, is to use the artificial making ridge of soil moved in to improve the original, makes the ridge ridge effectively stop the saline and alkaline water erosion bald spot in the face of land to administer the district, reduces peripheral saline and alkaline water erosion, administers the district for bald spot basic guarantee is provided; It is to administer the soil environment that district's herbage growth is grown in order to improve bald spot that bald spot is administered district's 5-10 centimetre of soil moved in to improve the original of interior interpolation, effectively play simultaneously desalinization of soil by flooding or leaching function, reduce saline and alkaline infringement to herbage, be beneficial to herbage growth, especially germination and the growth of seedling stage to grass seed provides soil environment preferably, to realizing that repairing purpose plays conclusive effect; After-culture herbage is to administer the grass seed that district's after-culture is suitable for this area growth at bald spot; The overlay film insulation is the plastic film for agricultural use that utilizes infiltration, breathes freely, cover the bald spot improvement district of after-culture herbage, realize insulation and guarantee light and effect, satisfy the herbage growth demand, provide good hydrothermal condition to the herbage early growth, seedling is then grown up strong and sturdy, firmly takes root and survive the winter, well turn green the coming year and vegetation forms very favourable.The invention solves the problem of the germination of high and cold lakeside area grassland bald spot high salinity obstruction after-culture grass seed, high and cold low temperature of herbage growth initial stage, make bald spot reparation district temperature improve 1-3 ℃; The quantity of emerging reaches 7,000 strains/m
2More than, with approximate at agricultural land soil planting forage grass emergence rate, cover degree improves 3～5 times, reaches 50%; Saline and alkaline reduces by 20%, and the moisture storage rate improves 10%; Ground biomass improves 10 accompanies, and forage yield reaches 38.5 ㎏/mus then, finally reaches high and cold lakeside wetland bald spot and repairs purpose.
