本文通过对吉林省70个旱田土壤氮素形态、含量、比例及其相互关系的研究,明确了用矿质氮总量推测碱解氮含量的可靠性。矿质氮总最与碱解氮的相关系数r=0.8106,相关达极显著水准;配置的回归方程为y=57.32+2.05x,回归关系达极显著水准,F=130.27。室内分析和田间试验检验结果证明,大多土壤实测的碱解氮同由回归方程推算的碱解氮数值很接近。用其指导施肥,同样获得了良好的增产增收效果。由此认为,花生产上可以推广应用。
Based on the research on soil nitrogen form, content and proportion in 70 drylands in Jilin Province, and their correlations, this paper clarified the reliability of estimating nitrogen content in alkali-hydrolyzed nitrogen by the total amount of mineral nitrogen. The correlation coefficient between mineral nitrogen and alkalized nitrogen was r = 0.8106, and the correlation reached a significant level. The regression equation of configuration was y = 57.32 + 2.05x, and the regression relationship reached an extremely significant level, F = 130.27. Indoor analysis and field test results show that most of the measured soil nitrogen in the soil with the regression equation deduced nitrogen hydrolysis value is very close. With its guidance fertilization, the same access to a good yield increase. Therefore, flower production can promote the application.
