摘要: 以两个杂交品种和两个优质品种为材料,比较分析了不同品种之间氮磷钾的浓度变化和吸收积累特性。结果表明:油菜子叶期氮磷钾浓度不高,幼苗期最高钾浓度在蕾苔期还有第二高峰。优质油菜中前期长势慢,但含氮率高;油菜整个生育期中以蕾苔期氮磷钾积累强度最大,尤其是钾,其次为栽后一个月至抽苔现蕾前,花期积累速度下降,果期不再积累钾,积累的氮磷也较少;杂交品种氮磷钾的积累有较明显的优势,特别是蕾苔期和苗后期,而优质品种则表现出一定的劣势。

Abstract: The contents and absorption of nitrogen, phosphorus and potassium of two hybrids and two yarieties of good qnality of oilseed rape were preliminarily studied. The results were shown as follows: The contents of nitrogen, phosphorus and potassium were the highest in the seedling period, but the content of potassium had another high peak in the bolting stage. The quality variety Zhongshuang 821 had higher contents in the seedling period. Nearly 80% of nitrogen, phosphorus and potassium accumulation were made in the seedling and bolting stages. The uptake and accumulation amout of N, P, K elements by the hybrid variety used in the trial were superior to those by the traditional variety, especially in the seedling and bolting stages. On the contary, the uptake and accumulation amount of N, P, K elements by the quality variety used in the trial were inferior to those by the common variety.

Key words: OILSEED RAPE, HYBRIDS, CULTIVATED VARIETIES, NITROGEN, PHOSPHORUS, POTASSIUM, ABSORPTION, ACCUMULATION
