到下世纪30年代,预计中国人口将达到16亿,对粮食的需求量尚需在现有基础上再增加3000亿斤。由于土地资源有限,今后的增产途径主要是提高单位面积产量,因此需要能增产20％—30％的作物新品种或称为超高产品种。本文指出,培育超高产品种,需要通过多学科合作研究,发掘新的作物种质资源,改进育种方法,在作物对水、肥资源和光能利用效率方面有进一步提高,育种目标才有可能实现。
By the 1930s, China’s population is expected to reach 1.6 billion. The demand for food will still need to be increased by 300 billion catties on the existing basis. Due to limited land resources, the main means of increasing production in the future will be to increase the yield per unit area. Therefore, new crop varieties that can increase yields by 20% -30% or super-high yielding varieties are needed. This paper points out that to cultivate super high-yielding varieties, it is necessary to explore new crop germplasm resources and improve breeding methods through multi-disciplinary cooperation research. It is necessary to achieve further improvement in crop water and fertilizer resources and light energy utilization efficiency and breeding objectives.
