Based on the atmospheric turbulence diffusion model, a three-dimensional numerical model was applied for predicting the cross-pollination rate distribution in the leeward area of windbreaks by considering actual weather observation data, daily fluctuation parameter of pollen release rate, pollen life during the flowering period, etc. Several cases of the cross-pollination effect of windbreak distributions in the field were simulated. It is demonstrated that windbreak nets and windbreaks plants or forests are effective in suppressing pollen dispersal and cross-pollination. By simulating pollen diffusion under actual weather conditions using this model, it is possible to evaluate the effect of cross-pollination by the windbreak facilities and give advice on how to set windbreaks for suppressing crossing.
