DA型玉米脱水剂的脱水效果及其对玉米营养品质的影响

Dehydration Effects of DA-Desiccant and the Impact on the Nutritional Quality of Maize

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。

Application effect of desiccant was studied in Xiangfang farm. The results showed that DA-desiccant could accelerate dehydration rate of maize grain, increase the yield of maize and could not nutritional quality of maize. After 28 d of treatment,the moisture content of grain of dosages of 900 mL/ha, 1 200 mL/ha, 1 500 mL/ha, 1 800 mL/ha, and the control were 28.67%, 26.36%, 22.20%, 20.51% and 38.90%, respectively. Compared to the control, the moisture content reduced 10.23% - 18.39%. Low dosages had no effects on quality of maize. DA-desiccant could significantly increase the kernel weight per ear and yield, the yield of maize was increased 654.3 kg/ha averagely.
