| 摘 要： | 对健宝播期、密度、施肥、灌水进行单因素试验，结果表明：健宝夏播亦可获得较高的生物产量，是等雨晚播和麦后复种较理想的饲料作物；春播健宝的适宜栽培密度为2.0×105株/hm2；追施尿素75kg/hm2草产量及施肥效率均较高；4次灌水较雨养条件下一次性刈割鲜草产量增加53.3%，二次刈割鲜草产量增加66.9%，健宝宜在具备灌溉条件的地区种植。

| Abstract: | The effects of sowing time,density,irrigation and fertilization on Jumbo were studied with single-factor experiments.The results showed:Jumbo was a ideal forage crop in late sowing for rain and multiple cropping after wheat.It's optimum sowing density was 2.00 10 5plant/hm 2.There were higher yields and more efficiency with 75.0 kg/hm 2 Urea application than those of others.Compared with those of non-irrigation,the yields of 4-time-irrigation were respectively increased by 53.3%, 66.9% in fresh forage yields of one-time-harvestand and two-time-harvest.Jumbo was suited to growing in areas with irrigation condition. |
