摘要
在河西绿洲灌区试验观察了生物质炭基肥对制种玉米的影响。结果表明,一次性基施生物质炭基肥1200 kg/hm^2时制种玉米折合产量最高,为15004 kg/hm^2,较不施肥处理(CK)增产22.9%,较当地常规施肥处理增产6.5%;籽粒品质指标最优,籽粒含水量最低,为178.6 g/kg;籽粒蛋白质含量、粗淀粉含量、粗脂肪含量均最高,分别为99.9、679.0、42.8 g/kg。可见施用生物质炭基肥可有效地促进制种玉米的生长发育,促进果穗增长增粗,提高玉米产量和玉米品质。生物质炭基肥对玉米提质增产增收效果显著,适宜在河西绿洲灌区及其他类似地区应用。
The effect of biomass carbon base fertilizer on corn seed production was observed in hexi oasis irrigation area.The results showed that the yield of corn seed production was the highest when using 1200 kg/hm^2 biomass carbon based fertilizer,which was 15004 kg/hm^2,22.9%higher than that under no fertilizer treatment(CK)and 6.5%higher than that under local conventional fertilizer treatment.The grain quality index was the best and the grain water content was the lowest(178.6 g/kg).The contents of protein,crude starch and crude fat in grains were the highest,which were 99.9 g/kg,679.0 g/kg and 42.8 g/kg,respectively.It can be seen that applying biomass carbon-based fertilizer can effectively promote the growth and development of corn seed production,promote ear growth and thickening,and improve corn yield and quality.The biomass carbon base fertilizer has a remarkable effect on corn quality and income increase,which is suitable for application in Hexi Oasis Irrigation Area and other similar areas.
