育秧是水稻生产上的第一个战斗,也是夺取高产的基础。秧苗是从种子萌发而逐步形成的,是种胚与外界条件如水分、养料(包括自身的贮藏物)、温度、氧气等不断进行新陈代谢的结果。一、稻谷萌发的物质基础水稻种子(植物学上称为颖果)是由果皮与种皮、胚、胚乳等部分所组成。胚是种子的主要部分,无胚就不会出苗。而胚乳所贮藏的物质则是胚萌发与初始生 Raising seedlings is the first fight in rice production and the basis for winning high yields. Seedlings are seed germination and the gradual formation of the embryo and the external environment conditions such as water, nutrients (including their own storage), temperature, oxygen and other continuous metabolism of the results. First, the material basis of rice germination Rice seeds (botany called caryopsis) is composed of peel and seed coat, embryo, endosperm and other components. Embryos are the main part of the seed and will not germinate without embryo. The material stored in the endosperm germination and initial embryo
