不同密度和施肥量对黔单19号的产量影响

Effects of Different Density and Application Amount on Yield of Qiandan 19(a Hybrid Maize Variety)

通过不同密度和N、P、K肥配方组合对黔单19号产量的影响试验，经模拟寻优分析，黔单19号产量大于637．46kg／667m^2目标产量的优化栽培方案：播种密度3760～3872株／667m^2，施氮19．76～22．72kg／667m^2，施磷13．33～15．79kg／667m^2，施钾11．46-12．99kg／667m^2。

Different density and application amount were tested in Qiandan 19 to study the effects on its yield. The results showed that the optimum cultivation model for over 637. 46kg/667m^2 was 3760 - 3872 plants/667m^2 of planting density, 19. 76 - 22. 72kg/667m^2 of nitrogen, 13. 33 - 15. 79kg/667m^2 of phosphorus and 11. 46 - 12. 99kg/667m^2 of potassium.
