肥料价格继续上涨,现在正寻求廉价而效率高的肥料。在那里,作为氮素肥料,为了比较使用硝态氮素或使用铵态氮素的时候,春麦和大麦的生长、产量及产量构成要素的差别,进行了肥料实验。实验进行两次,实验1供试春麦,实验2供试春麦和大麦。春麦和大麦种在营养钵里,放在人工气候室让其生长发育。氮素处理,分别使用硫酸铵和硝酸钾,实验1按45、90、135、180公斤/公顷四个等级,实验2按23、45、90、180、360公斤/公顷五个等级,在播种时施肥。另外,施用硫酸铵的时候,配合使用硝化抑制刑防止硝化。 Fertilizer prices continue to rise, and are now seeking cheap and efficient fertilizers. There, as a nitrogen fertilizer, a fertilizer experiment was conducted to compare the difference in growth, yield and yield components of spring wheat and barley when using nitrate nitrogen or ammonium nitrogen. The experiment was conducted twice, experiment 1 for spring wheat and experiment 2 for spring wheat and barley. Spring wheat and barley planted in a nutrition bowl and placed in a climatic chamber for growth. Nitrogen treatment, respectively, using ammonium sulfate and potassium nitrate, the experiment 1 by 45,90,135,180 kg / ha four levels, the second experiment 23,45,90,180,360 kg / ha five grades, sowing When fertilization. In addition, the application of ammonium sulfate, with the use of nitrification to prevent nitrification.
