摘要:
为促进玉米高产优质栽培，以先玉335为材料，硅肥浓度设置4个梯度，即0，100，200和400 mg?L-1，研究叶面喷施不同浓度硅肥对玉米产量和籽粒品质的影响。结果表明：随着叶面喷施硅肥浓度的增加，玉米株高、茎粗和产量均较对照有所增加，其中当硅肥喷施浓度为200 mg?L-1时效果最明显，与对照相比，株高增加10.42%，茎粗增加20.33%，产量增加6.22%，且差异达到显著水平；穗粗、百粒重、秃尖长、行粒数和穗粒数差异显著，穗长和穗行数差异不显著；品质性状中的可溶性糖、可溶性蛋白、油分、粗蛋白质和粗淀粉含量随着叶面喷施硅肥浓度的增加先升高后降低，当喷施浓度为200 mg?L-1时效果最明显，与对照相比，显著增加66.44%、25.23%、6.62%、4.23%和7.02%。可见，叶面喷施硅肥有利于提高玉米籽粒品质和产量，生产中推荐喷施浓度为200 mg?L-1。
Abstract:
In order to promote high yield and quality cultivation of maize，taking Xianyu 335 as the instruction material，we studied on the effect of spraying silicon fertilizer with different concentrations on the yield and grain quality of maize.The results showed that: with the increase of silicon fertilizer concentration,the plant height,stem diameter and yield of maize were all increased compared with CK.When the concentration of silicon fertilizer was 200 mg?L-1,the effect was the most obvious.Compared with the CK,plant height increased by 10.42%,stem diameter increased by 20.33%,and yield increased by 6.22%,and the difference reached a significant level.There were significant differences in ear diameter,100-grain weight,bald tip length,grain number per row and grain number per ear,but no significant differences in ear length and row number per ear.The contents of soluble sugar,soluble protein,oil,crude protein and starch increased 66.44%,25.23%,6.62%,4.23% and 7.02% respectively.It can be seen that spraying silicon fertilizer on the leaf is beneficial to improve the quality and yield of maize,and the recommended spraying concentration in production is 200 mg ? L-1.
