摘要
对健宝播期、密度、灌水、施肥进行单因素试验 ,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× 10 5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 5 3 3%,二次刈割鲜草产量增加 6 6 9%,健宝宜在具备灌溉条件的地区种植。
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.
