摘  要:
采用饱和 D—最优设计的方法,研究了松叶猪毛菜砾石荒漠草场灌溉与产量的关系,通过测定灌溉试验的各项参数,建立了不同灌溉量和牧草生育期灌溉次数对牧草产量影响的函数模型,同时确定了松叶猪毛菜砾石荒漠草场最佳灌溉量为950.7~1710.9m~3/hm~2,生育期最佳灌水次数为2(5、7月)~3(5、6、7月)次。

摘  要:
Using the method of saturated-D optimum design,the relation between irrigation and yield was studied in Salsola laricifolia gravel desert grassland.Each parameter was determined by ir- rigation test.The function model that the irrigation times in different stage of herbage influenced on the yield of herbage was set up,in the same time the optimum irrigation quantity was decided to be 950.7~1710.9m~3/hm~2,the optimum times in reproductive stage were two(in May and July)and three(in May,June and July).
