摘　　要：通过增施四种不同叶面肥对多年生青海冷地早熟禾、青海中华羊茅产量的试验可知,三效绿叶神对牧草产草量具有较为明显的增产作用,而磷酸二氢钾对牧草产籽量的增产作用较为明显,应进一步试验,以便为叶面肥在牧草增产方面的运用和推广提供依据。Adding four kinds of the different fertilizers on Poa crymophila and Festuca sinensis, The test shows that the role of the three effct Luyeshen significantly increased yield of pasture grass yield, And potassium dihydrogen phosphate on forage production of seed amount of increase is more obvious,it should be further testing in order to provide the basis for the use and promotion of foliar fertilizer in forage yield.
