施用氮磷钾肥对夏谷品质的影响

EFFECTS OF NITROGEN PHOSPHATE AND POTASH FERTILIZERS ON THE QUALITY OF SUMMER MILLET GRAIN

通过田问试验研究潮土、褐土和棕壤等不同土类的土壤施用氮磷钾化肥对夏谷米粒品质的影响。结果表明,氮肥、氮磷配合、氮磷钾配合施用均可明显提高夏谷米粒中氨基酸的总量及人体必需氨基酸的总量,差异极显著。同时可提高米粒中氮磷的含量,不同处理对氮素含量的影响依次为NP,NPK,N,ck;对磷素含量的影响依次为NPK,NP,N,ck。施钾肥可增加米粒中钾的含量。氮磷配合既可提高产量又能增加蛋白质和氨基酸含量。

This paper presents the results from field experiment concerning the effects of nitrogen,phosphate and potash fertilizers on the quality of summer millet grain in flovo-aguic soil, cinnamon soil and brown earth.Nitrogen combination of nitrogen and phosphorous fertilizers not only increase greatly the total content of amino acid of summer millet grain and the content of human essential amino acid individully which its difference is at the 0.01 probability level but increase the contents of nitrogen and phosphorous in grains.The most effects is abtained by NP treat on the nitrogen content of grain and then NPK,N and no fertilizer treat;But on the phosphorous content of grain,the most effects is NPK treat,and then NP,N,and nofertilizer treat.It could increase the content of potassium in grain to apply the potassium fertilizer. The combination of nitrogen and phosphorous fertilizers not merely could increase the yield of millet grain but increase the contents of protein and amino acid.
