| 摘 要： | 本文采用最优回归设计311-B方案,在靖宇县白浆土中低产田上研究了春小麦合理施肥问题,提出了春小麦产量与化肥有效成份N、P_2、O_5、K_2O用量之间拟合度较高的二项回归方程,探讨了化肥最佳养分用量,最佳产量及化肥有效成份的单素效应和交互效应。 |
| 关 键 词： | 靖宇山区 中低产田 春小麦 最佳产量 |
A STUDY ON THE MODEL OF RATIONAL FERTILIZITION IN MIDDLE- AND LOW-YIELDING FIELD OF SPRING WHEAT IN MOUNTAIN AREA OF JINGYU COUNTY |
|
| Abstract: | In this paper, the problem of rational fertilizer application in middle-and low-yielding field of spring wheat in mountain area of Jingyu County was studied by using optimum re- gression model 311—B. The quadratic regression equation between spring wheat and fertil- ization of N, P_2O_5, K_2O was established and the optimum nutrient quantity, optimum yield and effects of single fertilizer and their interaction were investigated. |
| Keywords: | Mountain area of Jingyu County Middle-and low-yielding field Spring wheat Optimum yield |
