Analysis on the Effect of Heavy Metal-Polluted Soil on Potato Breeding

This paper studies the effect of heavy metal-contaminated soil on the breeding of new potato varieties in view of the problems of low yield and high content of heavy metals in potatoes cultivated by traditional analysis methods. The growth indexes of new potato varieties were measured by various techniques, and the influencing factors of heavy metal-polluted soil were detected by the geographical detector. The soil index of heavy metal pollution was determined by Nemero comprehensive pollution index method. The index parameters and pollution index were taken as the parameters of the neural network, and the effect of heavy metal pollution on potato breeding was analyzed by the neural network. Compared with the traditional analysis methods, the results showed that the new potato variety cultivated by the applied analysis method has a higher yield (60–130%) and lower heavy metal content, which can better cultivate the offspring. Therefore, the analysis method of the effect of heavy metal-polluted soil on the new potato breeding has superiority.
