Abstract

The invention belongs to the technical field of crop fertilization, and in particular relates to a method for recommending potato phosphate fertilizer based on the combination of soil Olsen-P test and water and phosphorus integration. Water-phosphorus integrated phosphorus fertilizer topdressing recommendation for phosphorus requirements of potatoes in different growth stages, the beneficial effect of the present invention is that the combination of soil testing and water-phosphorus integration can make phosphorus fertilizer management more accurately match the phosphorus requirements of potato growth, and improve the phosphorus fertilizer of potatoes Utilization efficiency, compared with all basal application of traditional phosphate fertilizers, the method of the invention is accurate and efficient.

Description

technical field [0001] The invention belongs to the technical field of crop fertilization, and in particular relates to a potato phosphate fertilizer application method based on the combination of base fertilizer recommendation based on pre-sowing soil Olsen-P test and water and phosphorus integrated topdressing recommendation during growth period. Background technique [0002] Phosphorus is one of the essential elements for potato growth and yield formation. In the actual production of potatoes, the amount of phosphorus fertilizer is increasing. In particular, the survey of farmers shows that 99% of phosphorus fertilizer is applied in the form of base fertilizer, resulting in less than 15% of phosphorus fertilizer utilization efficiency, which is far lower. For field crops such as wheat and corn, therefore, it is imperative to reduce weight and increase efficiency of potato phosphorus fertilizer management. The method of soil testing and formula fertilization focuses on det...
