| Abstract: | Quadratic regression orthogonal rotational and sing＇e--factor randomized biock design were adopted, and effects of planting density, fertilization and seed coating on main agronomic traits and yied were researched in order to support techniques for high--yield cultivation o{ hybrid maize cultivar, ,Qiandan24. The results showed that the optimized cultivation techniques of Qiandan 4 for high--yield were that the planting density, N fertilizer, P fertilizer and K fertilizer were 4t70--4294 plants/667 ms ,22. 78--25.7 kg/667 ms ,13. 75--16.25 kg/667 ms and 9. 335--11. 005 kg/667 m2 , respectively. |
