在籽用豆类中，氮素（N）积累和生物量积累与种子生长密切相关。在不同环境条件下N积累的定量信息，即向叶分配的N，生物量中的N和向籽粒分配的N，要求建立一些作物生长模型，以对生产风险性进行评价。因此，对热带、亚热带环境中不同辐射、不同温度和不同水分亏缺水平下大豆（GlycineMaxL）、绿豆（Vignaradiata）和饲用豌豆（VignaUnauiculate）的这些过程进行了数量化分析。在整个环境中，直到成熟前的整个生长期间，净N积累与地上净生物量呈线性相关，大豆的比率高于绿豆和饲用豌豆。就这3种作物而言，在所有环境的营养生长期间，N的70％和积累生物量的50％被分配到叶。在所有环境的胀荚期间，每种作物籽粒N浓度是稳定的。在胀荚期间，大豆地上部份N的积累量比绿豆和饲用豌豆大。在变化很大的整个环境中，在胀荚期营养体N降低的范围内，荚的N积累常常超过地上部份净N积累。胀荚期间营养体N的下降是由于叶的减少所致，而茎中N不一定减少。胀荚期叶N的损失是由于叶的损失而不是叶N的减少。在研究的整个产量范围内，籽粒产量与成熟时地上部份净生物量成比例，籽粒N与地上部份积累的净N比例，大豆和绿豆更为明显。因此，环境因子对生物量和N素积累的影响，不能说明它们对产量生理学没有不同的作用。
In seed legumes, nitrogen (N) accumulation and biomass accumulation are closely related to seed growth. The quantitative information accumulated by N under different environmental conditions, namely N allocated to leaf, N in biomass and N assigned to grain, required some crop growth models to evaluate the production risk. Therefore, quantitative analysis of these processes of Glycine MaxL, Vignaradiata and VignaUnauiculate under different radiation, temperature and water deficit in tropical and subtropical environments was conducted. Throughout the environment, net N accumulation was linearly correlated with net ground biomass until full maturity, with a higher proportion of soybeans than mung beans and forage peas. For all three crops, 70% of N and 50% of accumulated biomass were distributed to the leaves during vegetative growth in all environments. The N concentration per crop was stable during the inflation of all environments. During the expander pod, the accumulation of above-ground portion N of soybeans was greater than that of mung beans and forage peas. In a wide variety of environments, N accumulation in pods often exceeds net N accumulation in aerial parts within the reduced range of vegetative body N during the expansion period. The decline of vegetative body N during the expansion of pod is due to the decrease of leaf, while the N in stem is not necessarily reduced. The loss of expansive leaf N is due to the loss of leaf rather than the decrease of leaf N. Within the entire range of production studied, grain yield was proportional to above-ground net biomass at maturity, and the net N ratio accumulated between grain N and aboveground parts, soybean and mung bean was more pronounced. Therefore, the impact of environmental factors on biomass and N accumulation does not indicate that they have no different effect on yield physiology.
