摘　　要：通过盆栽试验,研究了硅肥对糯玉米产量、品质及抗倒性的影响。结果表明:施硅能促进糯玉米根系生长发育,总根长平均比对照增加484.80 cm,根数平均比对照增加2.53条,每株根干重平均比对照增加2.55g;对糯玉米株高、穗位有不同程度的降低作用,株高分别比对照降低2.3 cm、3.2 cm、4.1 cm和5.5 cm,穗位高较对照平均降低3.7 cm;糯玉米茎粗明显增加,茎粗较对照平均增加0.16 cm;施用硅肥后,糯玉米品质得以改善,糯玉米粗蛋白、赖氨酸、淀粉和可溶性糖都有不同程度的增加,其中施用0.08g/kg干土的处理效果最佳,比对照分别增加7.18%、4.55%、1.70%和14.56%;产量显著提高,硅肥用量为0.12g/kg干土,产量最高,经济产量达197.8g/盆,比对照增产17.2%。The pot experiment was adopted to study the effects of silicon fertilizer on yield, quality and lodging resistance of waxy corn. The results showed that silicon fertilizer could accelerate growth root system of waxy corn. Its root Length, root numbers and dry weight of every plant＇s root were increased by 484.80cm,2.53,2. 55g recpectively as corparedcontrol. Silicon fertilizer could reduce plant height and ear height of waxy corn in different degree, and plant height was reduced 2.3cm, 3.2cm, 4. lcm and 5.5cm, and ear height was decreased 3.7cm compared with control, but stem diameter increased remarkably. The application of silicon fertilizer improved the quality of waxy corn. The content of crude protein, lysine, starch and sugar of waxy corn had increased in different degree, especially in the treat applied 0.08g./kg dry soil increased 7.18% ,4.55%, 1. 70% and 14.56% respectively The yield was improved evidently, the treat with 0.12g/kg dry soil had the highest yield, the economic yield of which reached to 197.8g/pot, increased 17.2% compared with control.
