豆类作物籽粒产量的限制因子多半是氮素不足,特别在共生固氮作用不良时更是如此。国内外许多研究者都认为在这种情况下施用氮肥是适宜的。其中某些研究者推荐施用高量的无机氮素。虽然积累了大量有关豆类作物的生化资料,但却很少报导过在供给高氮量的栽培条件下,豌豆种子生物化学成分方面的资料。 Most of the limiting factors for grain yield in legumes are nitrogen deficiency, especially when symbiotic nitrogen fixation is poor. Many researchers at home and abroad agree that it is appropriate to apply nitrogen fertilizer in this situation. Some of these researchers recommend the use of high levels of inorganic nitrogen. Although a large number of biochemical data on legumes have been accumulated, little is known about the biochemical composition of pea seeds under cultivation conditions that supply high nitrogen levels.
