以龙单25为试验材料,研究DA型玉米脱水剂的应用效果。结果表明,DA型玉米脱水剂可以明显加快玉米子粒的脱水速度,增加产量。处理后28 d,使用脱水剂剂量为900、1 200、1 500、1 800 mL/hm2处理的玉米子粒含水量分别为28.67%、26.36%、22.20%和20.51%,与对照相比,子粒含水量减少10.23～18.39个百分点。低剂量脱水剂对玉米品质无显著影响,可显著增加玉米的穗粒重和产量,平均增产654.3 kg/hm2。
Longdan25 was used as experimental material to study the application effect of DA corn dehydration agent. The results showed that DA corn dehydration agent can significantly accelerate the dehydration rate of corn grains and increase the yield. At 28 days after treatment, the water content of maize treated with dehydrating agent at doses of 900, 1 200, 1 500 and 1 800 mL / hm2 were 28.67%, 26.36%, 22.20% and 20.51%, respectively. Compared with the control, Water decreased 10.23 ~ 18.39 percentage points. Low dosage of dehydrating agent had no significant effect on maize quality, which could significantly increase the grain weight and yield of maize, with an average increase of 654.3 kg / hm2.
