| 摘 要： | 针对宁夏压砂瓜土壤连作产生的制约因素,充分利用压砂西瓜定植穴施基质和菌肥之间的相互作用,分析其在不同基质和菌肥条件下的产量效应,建立西瓜产量数学模型,采用频率分析法对产量模型进行模拟,结果表明产量大于27760.8 kg/hm2的方案中最佳农艺措施为：补水量3.358~3.864 kg/株次、施生物菌肥量138.5~162.65 g/定植穴、施基质量207.9~271.1 g/定植穴。跟据不同产量水平下的因素总结最优组合方案,可达到提高压砂西瓜的抗逆性、制约土传病害蔓延、增产量的效果。

Pressure Sand Watermelon: Optimization Scheme of Planting Substrate and Bacterial Manure |
| |
| 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. |
