Analytic hierar- chy process （AHP） was used to determine the weight of the index system of each level, and AHP and fuzzy comprehensive evaluation method were used to determine the selection steps for the third-party logistics providers for agricultural products. The method was proved to be scientific and reasonable through calculation examples.展开更多

[Method] The effects of four strobilurin fungi-cides on yield formation and quality were studied under disease-free conditions in the field. Two applications of each strobilurin fungicide were designed. The yield and commercial ratio for each application were investigated. [Results] The minimum dose for the obvious physical effect on potato and tomato and cucumber was lower than 133 mg/L , the dose for maximum effect on patoto and cucumber of the four stro-bilurin fungicides maybe also lower than 667 mg/L. The dose of fenaminstrobin and pyraoxystrobin for maximum effect on tomato maybe also lower than 667 mg/L. [Conclusion] The study suggested that enotroburin, fenaminstrobin, pyrametostrobin and pyraoxystrobin were able to increase the yield and ratio of high quality potato and cucumber and tomato.展开更多
