When the southwest university grass instry scientific experimental plot, discussed white three (Trifolium repens) + the reed shape sheep fescue (Festuca arundinacea) to mix broadcasts the lawn constructed plants, in base fertilizer N, P and K allocated proportion to the same year lawn community component and ultimate output influence. The result indicated that the N, P, K different allocated proportion dialog three and the reed shape sheep fescue early time time grows the influence not to be highly remarkable, 29, differences are after in December obvious, between each processing assumes the significance difference. And in processes 1 (N:44.3gP:375gK:100g), highly is highest, reaches 61.01cm; The total output grass quantity is also highest, the aerial parts fresh weight dry weight respectively reaches 294.61g,157.42g. The underground biomass fresh weight dry weight respectively reaches 25.54g,14.335g. In mixes broadcasts in the lawn, when sowing seeds is suitable quantity fertilizer for pure N 5Kg/Chinese acre, K2O 10Kg/Chinese acre, P2O5 10Kg/Chinese acre.

Abstract: The University of grassland science experimental field in the southwest, on the white clover (Trifolium repens) + tall fescue (Festuca arundinacea) mixed grass planting, the base fertilizer in the N, P and K ratio of the components and that grassland community The impact of total output. The results showed that, N, P, K ratio of the different White Clover and tall fescue early period of high growth is not significantly affected, on December 29 after the obvious differences, between the treatment was significantly different. In the address 1 (N: 44.3gP: 375gK: 100g), a high degree of the highest at 61.01 cm; the total yield is the highest on the part of the fresh weight of dry weight, respectively 294.61 g, 157.42g. Fresh-ground biomass dry weight respectively 25.54 g, 14.335g. In the mixed grass, planting at the most appropriate amount of fertilizer-N 5Kg / mu, K2O 10Kg / mu, P2O5 10Kg / acre.

Key words: N, P, K lawn fertilizer mixed level

Summary:At the southwest university grass instry science experiment farmland, study Trifolium repens and the Festuca arundinacea mix to sow lawn to set up to plant, the Ji be fatty medium the N, P and K go together with ratio to fall a set cent to the lawns in that year with total yield of influence.Result enunciation that N, P, K of dissimilarity go together with ratio dialogue three leafs and the Wei form sheep Mao earlier period period growth height influence don't show Zhao, December 29 after difference obvious, everywhere reason it present to show Zhao difference.BE a 1(N:44.3 gP:375 gK:100 g) times at the processing among them, height tallest, reach to 61.01 cm;Total proce grass quantity also tallest, ground upper part cent fresh and heavy stem heavy reach to a 294.61 g respectively, 157.42 g.The underground biomass is fresh and heavy stem heavy reach to a 25.54 g respectively, 14.335 g.The most suitable properly apply fertilizer quantity while sowing seeds in mix sow the lawn is pure the N 5 Kg/acre, the K2 O 10 Kg/acre, the P2 O510 Kg/acre.

Keyword:N, P, the K mix to sow lawn to apply fertilizer level
