云南气候复杂,素有“十里不同天”之说。但在水稻生产上,如品种、栽培技术与地区小气候巧相配合,小面积的高产则屡见不鲜。如1983年,省内自育的高产品种滇榆一号在大理市最高亩产达1000.43公斤,桂朝二号在宾川、永胜两县最高亩产达1024.08～1075.40公斤。我们曾于1982～1984年研究高产品种,各生育阶段植株内部营养及碳水化合物的动态与最后产量的关系,现简报如下。 Yunnan has a complicated climate and is said to have “ten different days”. However, in rice production, such as varieties, cultivation techniques and regional micro-climate co-ordination, small-area high yield is not uncommon. For example, in 1983, the high-yielding variety Dian Yu-1, a self-raised high-yielding variety in the province, reached a maximum of 1000.43 kilograms in Dali City. The highest per mu in the two counties of Binchuan and Yongsheng on the Gui and Chao Dynasties reached 1,024.08 to 1075.40 kilograms. We have from 1982 to 1984 study of high-yielding varieties, plant growth stages of internal nutrition and carbohydrate dynamics and the relationship between the final yield, are summarized below.
