不同施肥处理对高羊茅黔草5号农艺性状及种子产量的影响

Effects of Different Fertilization Combination on Agronomic Traits and Seed Yield of Qiancao 5(aFetuca arundinacea Variety)

为高羊茅品种黔草5号的高产制种施肥措施制定提供参考,在贵州省松桃苗族自治县大坪场镇高羊茅种子生产基地,采用完全随机区组试验设计,考察3个施肥处理(T1,尿素120kg/hm^2+磷肥225kg/hm^2+复合肥225kg/hm^2;T2,尿素150kg/hm^2+磷肥375kg/hm^2+复合肥375kg/hm^2;T3,尿素120kg/hm^2+磷肥225kg/hm^2+复合肥375kg/hm^2)对高羊茅黔草5号农艺性状及种子产量的影响。结果表明:T2处理的高羊茅黔草5号的田间农艺性状最优,种子产量最高,可达1519.52kg/hm^2。黔草5号大田高产制种肥料施用推荐采用尿素150kg/hm^2+磷肥375kg/hm^2+复合肥375kg/hm^2肥料组合。

The effects of three different fertilization combinations(T 1,120 kg/hm^2 urea+225 kg/hm^2 phosphorus+225 kg/hm^2 compound fertilizer;T 2,150 kg/hm^2 urea+375 kg/hm^2 phosphorus+375 kg/hm^2 compound fertilizer and T 3,120 kg/hm^2 urea+225 kg/hm^2 phosphorus+375 kg/hm^2 compound fertilizer)on agronomic traits and seed yield of Qiancao 5(a Fetuca arundinacea variety)were studied by a complete randomized block design in Dapingchang F.arundinacea seed production base,Songtao County to provide a reference for fertilization measure formulation in higher seed yield of Qiancao 5.Result:The agronomic traits of Qiancao 5 under T 2 treatment is the best among three treatments and its seed yield can reach 1 519.52 kg/hm^2.The fertilizer application scheme of 150 kg/hm^2 urea+375 kg/hm^2 phosphorus+375 kg/hm^2 compound fertilizer should be used in cultivation of F.arundinacea.
