在花生结荚后期叶面喷施500 ppm的调节膦,能明显地提高花生荚果产量,增产率约百分之十二至百分之十五,喷期过早或浓度过高则使增产幅度下降,甚至引起减产。在喷药时期与浓度合适的情况下,不仅产量增加、百果重、百仁重提高,而且,果仁肉蛋白质及油脂的含量均有所上升,品质得到了改善。叶面喷施调节膦使光合作用得到加强,地上部的生长受到抑制,营养物质的分配与积累亦发生了变化,根/冠比及生殖体/营养体比值上升.此外,后期无效花的减少亦有利于产量的提高。
In the peanut pod late leaf spraying 500 ppm of phosphine, can significantly improve the peanut pod yield, yield increased by about 12 percent to 15 percent, spraying early or too high concentration is to make the rate of increase Decline, and even lead to reduced production. In the spraying period and the concentration of the right circumstances, not only increased production, increased fruit weight, weight per 100 kernels, but also the content of protein and fat in nuts increased, the quality has been improved. Phosphorus application by foliar spray enhanced the photosynthesis, inhibited the shoot growth, changed the distribution and accumulation of nutrients, and increased the root / shoot ratio and genital / vegetative ratio. In addition, the decrease of late inefficient flowers Is also conducive to raising production.
