摘要
运用2因素4水平多年多点随机区组设计方法,探索不同栽植密度及施肥水平与华南5号木薯产量间关系。结果表明:华南5号在栽植密度为550~700株/667m2,施N3.9kg/667m2、P2O52.0kg/667m2、K2O7.8kg/667m2时可获最佳产量。
Using method of random group (zone) of two factors and four levels among different years and places to study the relationship between planting density, fertilizer application amount and the yield of Huanan No.5. The result shows that when selecting planting density as 550-700 seedling/ 667m^2; applying the amount of N 3.9kg/667m^2, P205 2.0kg/667m^2, K20 7.8 kg/667m^2, the highest yield can be achieved.
