王草和象草在云南省亚热带地区的适应性研究

对王草和象草在云南省亚热带地区的适应性研究结果表明，两者在产量和养分的季节变化动态上有一定差异，在早期生长速度，再生性，年总产量和抗寒性等方面差异较小，多次刈割利用时，两者均表现出再生性好，饲草产量高的特点，其鲜草，干物质和粗蛋白的年总产，象草平均为298t/hm^2,53.7t/hm^2和4．18t/hm^2，王草为276t/hm^2,58.2t/hm^2和4．30t/hm^2，种植利用时两者可相互替代。

Astudy on Adaptability of Elephant grass and king grass in the sub-tropical region of Yunnan Province, China

The adaptability of elephant grass and king grass in the sub-tropical region of Yunnan province was studied. The results showed that there were some differences on the seasonal change of yield and nutrient component, but little difference existed on annual total yield, regeneration ability, growth speed and cold resistance. When cut in growing season, performed the characters of high yield and strong regeneration, as the annual average yield of fresh grass, dry matter and crude protein could be 276 000 kg/hm 2, 53 700 kg/hm 2, 4 180 kg/hm 2 for elephant grass and 298000 kg/hm 2, 58 200 kg/hm 2, 4 300 kg/hm 2 for king grass.When planted the two grasses could substitute each other.
