寒地玉米幼苗早发增产技术研究

Studies on the Techniques of Stimulation Seedlings and Increasing Yield of Maize in Cold Region

以玉米品种吉单517为试材,于2010年在黑龙江省半干旱地区进行了玉米幼苗早发抗旱增产技术的研究。结果表明:各处理生育期均较对照提前2 d,分别增产10.7%、6.7%、12.5%、4.9%、5.5%、4.5%,其中,磷酸二铵水处理、磷酸二铵+活化剂水处理与对照产量差异达极显著水平,效果显著。

Taking maize variety of Jidan 517 as experimental material,the techniques of stimulation seedlings and the resistant to drought and increase yield of maize were conducted in the semi-arid areas of Heilongjiang province in 2010.The results showed that the growth periods of the treatments were all 2 days earlier than that of the control,and the yield of treatments were increasing by 10.7%、6.7%、12.5%、4.9%、5.5%、4.5%,respectively.The yields of the treatment of water with diammonium phosphate and the treatment of water with the commixture of diammonium phosphate and activator were remarkable significance different with the control.
