种子的纯度、发芽能力、幼芽的生活力、播种前的准备等等都会影响作物的收成。而在这些因素中又以种子储存的营养物质多少对收成的影响较大。在一般情况下,留种植物的培养条件越好、种子储存得越好,种子中的营养物质就越多,由这种种子生成的植物,收成会较好。不过,也可以人为地给种子补充营 The purity of seeds, the ability to germinate, the viability of sprouts, the preparation before sowing and so on all affect the crop harvest. Among these factors, the storage of nutrients by seeds has a greater impact on the harvest. In general, the better the culture conditions of the retained plant, the better the seeds are stored, the more nutrients in the seeds, and the plants produced from this seed will have a better harvest. However, artificial seed can also be added
