| 摘 要： | 河套灌区甜菜施肥问题,未能发展到根据肥料效应函数计算的数量化阶段,阻碍了科学施肥水平的提高。根据＂最佳模拟配合法＂的要求,设立6×7个处理试验,采用D饱和重叠试验,测得各种施肥水平的产量,借助微机,建立相应数学模型,模式均通过极显著检验。对模式进行各种处理,寻求各种施肥方案对产量的影响,探索投资少、经济效益高的施肥方案。

| Abstract: | The level of beet fertilization in Hetao irrigation area has not yet to be developed the quantity stage in accordance with the calculation of fertilizer response function,so it has an obstacle on scientific fertilization.The ＂best simulated with the law＂ requirements,experiment has been adopt overlap tests saturated D,set 6 ×7 treatments,measured levels of varieties of fertilizer production and set up the corresponding mathematical models which have passed the very significant test.A variety of models were treated to look for various application programs on the impact of production and explore of low investment and high economic efficiency fertilization program. |
