为了摸索在一定的氮肥水平下,不同数量的磷肥对小麦的增产效果和经济效益,从中找出最佳的氮磷比例,我们于1982年秋,在张垸公社孙庄大队下冲生产队社员潘正德的责任田里进行了氮磷配比试验。 一、试验概况 试验地为冷白土,碱解氮含量86.1ppm,速效磷2.3ppm,速效钾133ppm。前作棉花,供试小麦为鄂麦6号,于10月22日播种。 试验以亩施4,000斤土杂肥为对照,在这
In order to explore at a certain level of nitrogen fertilizer, different amounts of phosphorus on wheat yield and economic benefits, to find the best proportion of nitrogen and phosphorus, we in the autumn of 1982, Zhang embankment commune Sunzhuang Brigade under the production team members pan The responsibility of Masanori field nitrogen and phosphorus ratio test. First, the test profile Test for the cold white clay, nitrogen content of 86.1ppm, available phosphorus 2.3ppm, available potassium 133ppm. Former cotton, test wheat Emai 6, sown on October 22. Tests to 4,000 pounds of miscellaneous fertilizer Mushi soil control, in this
