昆明地区的水稻产量已由1949年的亩产373斤,提高到616斤(1979年)。今年,官渡区广卫生产队的高产试验田已把亩产刷新到1379.2厅。但高产田在稻田面积中占的比例,高产田产量在水稻总产量中占的比例,很不稳定,以1973—1979年为例,亩产800斤以上的高产田占稻田面积的比例为0.3—28.7％,占水稻总产量的0.7—35.0％;亩产501—800斤的稻田占总面积的26.5—83.2％,占总产量的34.7—85.9％;亩产500斤以下的低产田占稻田总面积的8.2—73.1％,占总产量的5.1—64.6％。就地理分布来看,亩产800斤以上的高产田主要出现在海拔1650—1700公尺的土质、水利、气候较好,
The output of rice in Kunming has risen from 373 kg per mu in 1949 to 616 kg (1979). This year, Guandu District Guangwei production team trial production field has shrimp acres to 1379.2 hall. However, the proportion of high-yielding fields in the area of rice fields and the proportion of high-yielding fields in the total output of rice are very unstable. Taking the period from 1973 to 1979 as an example, the proportion of high-yield fields with a yield over 800 kg in the area of paddy fields was 0.3 -28.7%, accounting for 0.7-35.0% of the total output of rice; paddy fields yielding 501-800 kg per mu account for 26.5-83.2% of the total area, accounting for 34.7-85.9% of the total output; The total area of 8.2-73.1%, accounting for 5.1-64.6% of the total output. In terms of geographical distribution, high-yield fields of more than 800 kg per mu mainly appear in the soil of 1650-1700 meters above sea level with good water conservancy and climate,
