高寒地区人工草地建植技术与效益初步分析

Preliminary Analysis on Establishing Technology and Benefits of Artificial Grassland in the Alpine Areas

本文通过在新疆昭苏马场高寒地区进行人工草地建植技术的试验研究,采用禾草与豆科草混播的方法,以大麦地套种人工混播草地模式进行两次播种。结果表明:建植人工草地套种大麦模式,第一年牧草生长良好、牧草可以安全越冬,禾草出苗率可以达到80%,豆科出苗率达到85%,人工草地建植成本为3385.95元/ha,大麦产值为5184元/ha,套种效益明显,第一年即可收回成本的153.1%。建植二、三年后,草地牧草产草量可相对稳定,达到建植生产需求目的,其在高寒地区建植人工草地是可行的,在畜牧业生产过程中可以推广应用。

Establishing technology of artificial grassland was studied in alpine areas of Zhaosu Horse Farm. Perennial grasses and Leguminous grass were selected to sow in the mixture way and were sew two times by the model of inter-planting of barley and artificial grassland mixture sowing. The results showed that： In the model of inter-planting barley in artificial grassland, forage grew well in the first year and could safely get through winter rest. Germination rate of perennial grasses and Leguminous grass could respectively reach 80% and 85%. Establishing cost of artificial grassland was 225.7 yuan RMB/667m2, and output value of barley was 345.6 yuan RMB/667m2. Inter-planting effect was remarkable, so the cost of 153.1% could be obtained in the first year. After two or three years of establishing artificial grassland, grass yield of pasture was relatively stable and could get to the production requirement of establishing artificial grassland. Establishing artificial grassland can apply to both alpine areas and the production process of animal husbandry.
