多年生饲草玉米品种SAUMZ1号引种栽培试验

Perennial Forage Maize Variety Introduction and Cultivation Test of SAUMZ1

为多年生饲草玉米品种SAUMZ1号在贵州的推广应用提供科学依据,于2009年从四川农业大学玉米研究所引进玉米品种SAUMZ1,并在绿茵畜牧有限公司的坝地进行了播期、密度、播种深度、施肥和采收茬数对饲草玉米品种SAUMZ1号生育和产量的影响试验。结果表明:最佳播种期为4月中下旬,播种深度为15～20 cm,播种密度为2.5万株/hm2,生长期间施尿素450～600kg/hm2作追肥,刈割鲜草3次,在此条件下可获得较高的产量。

In order to provide a scientific reference for generalization and application of perennial forage maize SAUMZ1 in Guizhou,which was introduced from maize research institute of Sichuan Agricultural University in 2009,a field experiment was conducted to study the effects of sowing stage,density,sowing depth,fertilization and harvest times on growth and yield of SAUMZ1 in Green livestock Co.,LTD.The results showed that the optimum sowing stage,depth,density,topdressing amount of urea and harvest times were mid-late April,15-20 cm,25 thousand plants per hm2,450-600 kg/hm2 and three times,respectively.Under these conditions,the highest yield of forage maize could be got.
