摘要
对龙燕1号燕麦(Avena sativa cv.Longyan No.1)进行不同施氮(以下简称施N)处理,探讨不同施N对其种子产量和产量性状的影响。结果表明,龙燕1号燕麦在施N量60 kg/hm^(2)时株高最高、主穗籽粒数最多、主穗穗粒最重、千粒重最重、轮层数最多,在施N量90 kg/hm^(2)下穗长最长、主穗小穗数最多。龙燕1号燕麦在施N量60 kg/hm2处理下种子产量达到最高,为4760.2 kg/hm^(2),其种子产量与施N量间的数量关系符合y=-0.0499x^(2)+8.3261x+4403(R^(2)=0.965)。株高和千粒重对种子产量的增加直接作用效应最大。因此,在哈尔滨地区燕麦种子生产中,施N量为60 kg/hm^(2),种子产量最高且经济有效。
To explore the effects of different nitrogenous fertilizer treatments on the seed yield and yield characteristics of Avena sativa cv.Longyan No.1.The results showed that Longyan No.1 had the highest plant height,the highest number of grains in the main spike,the heaviest grains in the main spike,the heaviest thousand grain weight,and the highest number of whorls at a nitrogen application rate of 60 kg/hm^(2).Under a nitrogen application rate of 90 kg/hm^(2),the longest spike length and the highest number of spikelets in the main spike were observed.The highest seed yield of Longyan No.1 was 4760.2 kg/hm^(2) under the N application rate of 60 kg/hm^(2).The quantitative relationship between seed yield and N application rate was y=-0.0499x^(2)+8.3261x+4403(R^(2)=0.965).The direct effect of plant height and thousand grain weight on the increase of seed yield is the greatest.Therefore,in the production of oat seeds in Harbin area,a nitrogen application rate of 60 kg/hm^(2) results in the highest and economically effective seed yield.
