从南斯拉夫引进的SC704玉米单交种在我区多点示范种植,亩产低者350—400公斤,高者800—900公斤,产量高低悬殊.究其原因,主要是各点对其丰产栽培要点尚不清楚.为探讨并掌握其丰产栽培技术,我们于1985年做了不同肥、水、密三因子的回归试验.一、试验方法本试验采用二次通用旋转组合回归设计,共设20个处理,小区面积36平方米(行长10米,宽3.6米),计产面积20.4平方米,各小区随机排列.试验因子及水平编码见表1.
Introduced from Yugoslavia SC704 maize single cross-species demonstration in my area more demonstration, the lower the yield per mu 350-400 kg, the highest 800-900 kg, the output gap between the high, the reason is mainly the points of its high yield cultivation points It is not clear.In order to explore and master its high-yielding cultivation techniques, we did a regression test of three factors of different fertilizer, water and dense in 1985. First, the test method This experiment using the second universal rotary combination regression design, a total of 20 Treatment, the plot area of 36 square meters (length of 10 meters, 3.6 meters wide), total area of 20.4 square meters, the district randomly arranged in. Test factors and level coding in Table 1.
