课题承担的草场为沼泽草甸草原,因低温和积水不能利用。为使草场资源得以发挥,本课题采用工程治理,生物改良和耕作措施相结合,通过对土壤水份的调控达到治理改良的效果。经运用施肥方法改起的草场比对照每公顷产干草2253.5千克,增产207.5%,人工种草增产84.5%,翻耙增产45.7%,松土增产6.2%,改良后草场平均公顷产干草3727.5千克,比改前增产105.4%。改良的草场可用放牧牛、羊及利用蓄水养鹅和养鱼。由于上述试验研究的开展形成了对三江低湿草场改良技术体系,以及草场用于放牧养殖牛、羊、蓄水养鹅和养鱼的水草资源综合利用的实体模式。
The task of the grassland for the marsh meadow grasslands, due to low temperature and stagnant water can not be used. In order to make grassland resources play its role, this project adopts the combination of engineering management, biological improvement and tillage, and achieves the result of improvement through the regulation of soil moisture. Compared with the control, the grassland changed by fertilization method produced 2253.5 kg of hay per hectare, an increase of 207.5%, artificial grass yield 84.5%, overturning rake 45.7%, loose soil 6.2%, improved hay an average of 3727.5 kg of hay, 105.4% increase than before the change. Improved pasture grazing cattle, sheep and the use of aquaculture goose and fish. As a result of the above experimental research, a solid technical model for improving the technical system of Sanjiang low wet grassland and comprehensive utilization of grassland resources for grazing cattle, sheep, aquaculture geese and fish culture has been formed.
