采用田间小区试验,研究了不同施肥量对湘杂油763生长及产量的影响.结果表明:施肥能显著增加油菜根茎粗、叶长、干物质累积量和籽粒产量,但对油菜株高、有效分枝数、叶宽影响不明显.所有处理中,以N、P2O5、K2O、B施用量为180、90、158、0.90 kg/hm2产量最高,达2 300 kg/hm2.施肥能促进油菜对养分的吸收,籽粒产量干物质累积量与施肥量成正相关关系.

Field plot experiments were conducted to investigate the effects of different fertilization levels on growth and yield of Xiangzayou763. The results showed that fertilization can significantly increased diameter of rootstalk, length of leaf, dr）, matter accumulation amount and grain yieht, but have no obvious impacts on height of plant, effective branches and width of leaf. Among all of treatments, the highest yield reached 2 300 kg/hm2 when fertilization level of N, P2O5, K2O and B was 180, 90, 58 and 0.90 kg/hm2, respectively. Therefore, fer...
