A Italian ryegrass CV Suxuyan 1 was used to study the effects of different additional nitrogen application levels (0 kg/hm~2,150 kg/hm~2,300 kg/hm~2,450 kg/hm~2,and (600 kg/hm~2)) on dry matter yield,digestible dry matter yield,total soluble sugar content,crude protein content,cellulose content,hemicellulose content,and lignin content.

以多花黑麦草苏畜研 1号为材料 ,研究了追施不同氮量 (0kg/hm2 、15 0kg/hm2 、30 0kg/hm2 、4 5 0kg/hm2 、6 0 0kg/hm2 )对多花黑麦草干物质产量、可消化干物质产量、可溶性总糖含量、粗蛋白含量、纤维素含量、半纤维素含量和木质素含量的影响。

The greatest increase in dry matter yield occurred before the first cutting, and the fastest daily average increase in height occurred before the second cutting.

结果表明,苜蓿生长的高峰期在第3年,单株干物质产量最大生长速度在第1茬,日均增长速度最快为第2茬;各龄1茬的单株干物质产量占当年的41。

Orthogonal design was used to determine the effects of combinations of N,P and K on plant height,tillers and DM yield in Pennisetum purpureum.

采用正交试验设计,以单次干物质产量、年总干物质产量、株高、分蘖数为指标,测定了氮、磷、钾不同组合对德宏象草Pennisetum purpureum生长的影响。

The results were as follows: (1) The dry matter yields (DM) of 42 varieties in 2004 and 2005 were higher than those in 2002, and the yield in 2002 was higher than that in 2003, due to the low temperature and high rainfall in 2003; (2) DM yields .

结果表明:(1)不同秋眠级苜蓿的干物质产量均呈第4年≈第3年>第1年>第2年的趋势,其中第2生长年(2003年)天气温度较低和降雨过量是其低产的直接原因;(2)在郑州地区,4、2秋眠级苜蓿干物质产量显著高于非秋眠品种,其他秋眠或半秋眠苜蓿产量也程度不同地高于非秋眠苜蓿;(3)不同秋眠级的苜蓿品种第1茬产量最高,其次为第2、3、4茬,第5茬产量最低;(4)苜蓿的秋眠级与年干物质产量、粗蛋白质(CP)含量呈负相关,与粗纤维(CF)呈正相关,认为郑州地区不宜选用非秋眠品种。
