微肥对晋北地区黍子产量品质及收益的影响

Impact of Microfertilizer on Yield Quality and Income of Millet in Northern Shanxi

以复合肥和生物有机肥的不同配比模拟不同种植环境,研究了庄稼大力神牌微肥使用量对黍子产量、生长指标、营养品质及经济收益的影响。结果表明微肥使用量对黍子产量、株高、茎基粗、容重,及黍米还原糖、蛋白质和脂肪含量有显著影响,对黍子穗质量、穗长、百粒质量和黍米直链淀粉影响不显著。当微肥施用量为15 kg/hm^(2)时株高值较大,产量、经济效益、还原糖含量较高;当微肥使用量30 kg/hm^(2)时营养指标和口感较好。微肥使用量为45 kg/hm^(2)时黍子植株的抗倒伏性较强。

In this experiment,different ratios of compound fertilizer and bio-organic fertilizer are used to simulate different planting environments,in order to study the effect of"Hercules"micro-fertilizer on the yield,growth index,nutritional quality and economic benefits of millet.The results shows that the application of micro-fertilizers had a significant effect on the yield,plant height,stem base diameter,test weight,and reducing sugar,protein and fat content of millet,simultaneously had no significant effect on the ear weight,ear length,100-grain weight of millet and amylose in millet.When the usage amount of micro-fertilizer is 15 kg/hm^(2),the plant height value is larger,and the yield,economic benefit and reducing sugar content are higher,when the usage amount of microfertilizer is 30 kg/hm^(2),the nutritional index and taste are better.The lodging resistance of millet plants is stronger when the amount of micro-fertilizer is 45 kg/hm^(2).
