方玉36是河北德华种业有限公司于2005年冬在海南以自选系F501为母本、自选系H09为父本组配杂交而成的中晚熟玉米单交种,适宜在河北省中晚熟春播玉米种植区种植。近年在承德种植面积不断增加。本试验研究方玉36的产量及其构成要素在不同密度条件下的变化特征,探索出承德区域内种植条件下栽培的最佳密度,为方玉36的高产栽培提供理论依据,加快了方玉36玉米新品种的推广步伐。
Fangyu 36 is a middle-late maturing corn variety crossed by Hebei Dehua Seeds Co., Ltd. in the winter of 2005 in Hainan Province with self-selected line F501 as female parent and optional line H09 as male parent. It is suitable for middle-late maturity in Hebei Province Spring sowing corn planting areas. In recent years, Chengde planting area is increasing. In this study, the yield and its components of Fangyu 36 under different densities were studied. The optimum density of cultivated plants under the planting conditions in Chengde was explored to provide theoretical basis for the high-yielding cultivation of Fangyu 36 and accelerate the growth of Fangyu 36 new varieties of corn to promote the pace.
