Diversified planting method for improving phosphorus fertilizer utilization efficiency of sunflower in saline-alkali soil
The application belongs to the technical field of planting and fertilization, and particularly relates to a diversity planting method for improving phosphorus fertilizer utilization efficiency of sunflower in saline-alkali soil, which solves the technical problem of low phosphorus fertilizer utilization efficiency of the existing sunflower planting method. The method first uses desulfurized gypsum as a soil conditioner, plants sunflower by ridge planting, and plants wild soybean, sueda and alfalfa in diversity, realizes inter-ridge crop coverage to reduce evaporation and suppress salt, cooperates with a composite phosphorus-solubilizing microbial agent containing bacillus subtilis, bacillus megaterium and pseudomonas fluorescens, enhances soil phosphorus-solubilizing microbial activity, and through precise water and fertilizer integrated management during the growth period of the sunflower, according to the needs of different growth periods, urea, potassium sulfate, potassium dihydrogen phosphate and other fertilizers are driped to ensure sufficient and balanced nutrition supply. The diversity planting method significantly improves the phosphorus fertilizer utilization efficiency in saline-alkali soil, is suitable for practical application in saline-alkali soil, and has wide popularization value.
