Abstract: In view of the restrictive factors of soil continuous cropping in Ningxia Watermelon, the interaction between the substrate and the bacterial manure was fully utilized to analyze the yield effect under different substrates and bacterial manure, and established the mathematical model of the yield.The yield model was simulated by frequency analysis. The results showed that the yield was large. The best agronomic measures in the 27760.8 kg/hm2 scheme were: water supplement 3.358~3.864 kg/, 138.5~162.65 g/ planting acupoint and base quality 207.9~271.1 g/ planting point. According to factors of different yield levels,summed up optimal combination scheme, which can improve stress resistance of watermelon, restrict spread of soil borne diseases and increase yield.
