【摘要】 通过盆栽单因子试验,结果表明:氮肥对热研6号珊状臂形草分蘖枝、茎长和干物率均有显著影响。N3(尿素用量为0.9g/盆)和N4处理(尿素用量为1.2g/盆)的分蘖枝增加最快为0.46枝/盆·d,N3处理的茎伸长生长速率最快为0.82cm/d,N2处理(尿素用量为0.6g/盆)的干物率最高为41.85%。更多还原

【Abstract】 A potted single factor experiment was conducted. The results showed that the nitrogen fertilizer hadremarkable effect on the vegetable stems, the length of stem and the dry matter rate of the Brachiaria brizan-tha cv,Regan No.6. In the experiment, the vegetable stems with N3 (0.9 g/pot) and N4 (1.2 g/pot) grew by therate of 0.46 stem /pot/day at the uttermost. The growing speed of stem with N3 (0.9 g/pot) was fastest, reaching0.82 cm/day. The dry matter rate with N2 (0.6 g/pot) was the highest, reaching 41.85%.更多还原
