本文讨论了高产条件下不同施氮量对花生某些生理参数的影响。结果表明，在一定范围内，施氮对群体叶面积系数、净光合强度、干物质生产、Ｖ／Ｒ率、暗呼吸等参数产生正效应；对Ｒ／ＴＤ和经济系数产生负效应；能够产生最高总生物产量的施氮量并非是英果产量的最适施氦量。因此，干物质分配系数应作为高产花生经济，合理施氮的重要参考指标。）；产量（Ｙｐ）＝５．９３６４＋０．０１２３７ｘ一６．４×１０－５Ｘ２（ｒ＝０．９７４５），其中Ｘ为施氮量。当Ｘ＝１４４时，总生物量取得极大值ＹＴ（ｍａｘ）＝９．８（ｔ／ｈｍ２），当Ｘ＝２９６．６时，产量达最大值Ｙｐ（ｍａｘ）＝２６．５（ｔ／ｈｍ２）。由此可以看出，取得最高总生物量的施氮量，对产量来讲并非是最适量。施氮同时对干物质分配产生很大影响。在每公顷施０～１８０ｋｇ氮范围内，随施氮量增加，群体Ｖ／Ｒ率（营养体／生殖体）呈线性增长，符合方程ｙ＝０．８２２０＋０．２０７ｘ（ｒ＝０．８６３０），即每增加１ｋｇ氮，Ｖ／Ｒ率提高０．２１。但每公顷施氮超过１８０ｋｇ时，Ｖ／Ｒ率又有下降趋势，这可能与过量氮对植株产生肥害，而使整个群体发育不良有关。与Ｖ／Ｒ率相反，群体经济系数和Ｒ／ＴＤ（生殖体／总生物量）随?
This article discusses the effects of different nitrogen application rates on some physiological parameters of peanut in high yielding conditions. The results showed that within a certain range, nitrogen application had a positive effect on parameters such as leaf area index, net photosynthetic rate, dry matter production, V / R rate and dark respiration, negative effect on R / TD and economic coefficient, Nitrogen content of the highest total biomass is not the most suitable application of helium for the production of British fruit. Therefore, the dry matter partition coefficient should be used as a high-yield peanut economy, an important reference for a reasonable nitrogen application. ); Yield (Yp) = 5.9364 + 0.01237x-6.4x10-5X2 (r = 0.9745), where X is the amount of nitrogen applied. When X = 144, the maximum biomass YT (max) = 9.8 (t / hm2) and the maximum biomass Yp (max) = 26.5 hm2). From this it can be seen that the highest NUE for total biomass is not the optimum for yield. Nitrogen fertilization at the same time have a significant impact on the distribution of dry matter. Within the range of 0-180 kg nitrogen per hectare, with the increase of nitrogen application rate, the population V / R ratio (vegetative / genital) increased linearly with the equation y = 0.8220 + 0.207x (r = 0.8630) That is, for each additional 1kg of nitrogen, the V / R ratio increases by 0.21. However, when the nitrogen application rate exceeds 180kg / ha, the V / R rate has a downward trend, which may be related to the excess nitrogen fertilizer on the plants and the poor development of the entire population. In contrast to the V / R ratio, the coefficient of population economy and R / TD (gonadal / total biomass)
