肥料与农药混用,如何掌握它们的配伍和比例,是比较复杂的问题。既要考虑作物营养,又要顾及治虫和除草效果,涉及的因素很多。如土壤肥力,肥料成份及养分含量,作物种类,药剂类型、杂草、病虫害程度和有效防治时期、残毒以及配伍禁忌等等。在配制前一定要根据作物、肥料、农药性质与防治对象的特性,合理选定。在生产上,首先应采用经实践证明行之有效的混合类型。一般来说,具有高度选择性的除草剂如2,4—D类,以适宜剂量与化肥混用时,对作物不会发生危害,且能提高除草效果。因此,应提倡2,4—D同化肥混用。
Fertilizer and pesticide mix, how to master their compatibility and the ratio is a more complex issue. It is necessary to consider crop nutrition, but also take into account the pest control and weeding effect, involving many factors. Such as soil fertility, fertilizer composition and nutrient content, crop type, type of medicament, weeds, pest and disease degree and effective control period, residual poison and compatibility taboo and so on. Before the preparation must be based on crops, fertilizers, pesticides and the nature of the prevention and treatment of objects, a reasonable choice. In production, the proven mix of proven types should first be used. In general, highly selective herbicides, such as 2,4-D, are not harmful to crops when combined with fertilizers in suitable dosages and enhance herbicidal efficacy. Therefore, 2,4-D should be promoted with the use of chemical fertilizers.
