任何作物高产都是良种、良法、良候(适宜的气候条件)三者有机结合的结果。粳稻良种“滇榆一号”(简称“滇榆”,下同)的问世,展示了高原水稻的生产潜力。“滇榆”对澄江的气候适应性如何,能否进一步充分利用澄江的光、热、水资源,要获得高产需要采取何种农业技术措施,便是本项研究的目的所在。
The high yield of any crop is the result of organic combination of good seed, good law and good weather (suitable climatic conditions). The advent of japonica rice variety “Dian Yu 1” (referred to as “Dian Yu”, the same below) shows the production potential of plateau rice. It is the purpose of this study to see how the “Dian Yu” adapts to the climate in Chengjiang and whether it can further make full use of the light, heat and water resources in Chengjiang and what agricultural techniques are needed to achieve high yields.
