我们在水稻高产的形态生理研究过程中,观察和测定了高产水稻不同生育阶段的长势长相,以及稻株吸收氮、磷的变化,试图从中找出常规水稻亩产超1100斤,杂交水稻亩产超1200斤的长势长相和营养特点,以便为指导大面积生产提供措施依据。 In the process of morphological and physiological research on high-yielding rice, we observed and measured the growth of rice at different growth stages and the changes of nitrogen and phosphorus uptake by rice plants. We try to find out that the yield of conventional rice is over 1100 kg per mu and that of hybrid rice per mu Over 1200 pounds of growing looks and nutritional characteristics, in order to guide the production of large-scale measures to provide a basis.
