摘要
以吉油1号玉米为试材,研究8个不同播期和4个不同收获期对玉米产量的影响。通过对生长发育规律及对干物质积累、灌溉速率、容重、产量进行相关分析,确定4月30日左右为吉油1号玉米的最佳播种期,10月5日左右为最佳收获期。
Taking Jiyou No. 1 as experimental material,the effects of 8 different sowing-date and 4 different harvest-time on maize yield were conducted. After correlation analysis of the raw of growth and development, dry matter accumulation, rate of filling, bulk density and yield, it concluded that the best sowing-time was on 30th in April and the best harvest--time was on 5th in October.
