施用氮素对高寒地区混播人工草地的影响
Effects of Nitrogen on Cultivated Grassland in Alpine Region
摘要
Abstract
[ Objective ] This research studied the effects of nitrogen on the productivity of cultivated grassland in an alpine region, and the conclusion will helpful for the study of cultivated grassland. [Method] The cultivated grassland in the hills of Zhaosu Horse Farm of Yili was studied in this research. There were different usage amounts of urea on different soils. Outputs, different kinds of weeds and percents of nutriment of them were compared in this research as well, and then the best usage amount of urea was obtained. [Result]The best usage amount of urea is 7.5 g/m2, and the best time of harvest is at autumn, between the last days in July and the earliest days in August. Following what is said above, the most output can be obtained, that is 4 997. 21 kg/hm2. [ Conclusion] Using nitrogen in soil can increase the outputs of the cultivated grassland, and can insure the quality of pastures out of affection.关键词
