The anxiety of farmers is closely related to their survival and daily life, and the prevention and control of locusts are closely related to their survival. The prevention and control of locusts is related to farmers’ food production and safety, so farmers bear the survival and life pressure brought by locusts. Their anxiety psychology not only lies in dealing with locusts, but also requires emotional and psychological adjustment for treatment.

Firstly, 1,184 farmers aged 23-31 from a certain city were randomly selected. Secondly, the Perceived Social Support Scale, Basic Psychological Needs Scale, Depression Anxiety Stress Scale, and Life Satisfaction Scale were used to score the anxiety psychology of farmers. Finally, SPSS 23.0 statistical software, analysis of variance, and t-test were used.

After comparing the scoring results of various scales, it was found that the positive prediction of understanding social support for farmers’ satisfaction was t=15.471, P<0.001, and the positive satisfaction with basic psychological needs was t=6.205, P<0.001. The combined understanding of depression, anxiety, and stress emotions for basic psychological needs of social support was t=-5.963, P<0.001. Overall, the best effect was achieved by adjusting farmers’ basic psychological needs and satisfaction.

Depression and anxiety, combined with basic psychological needs, have a greater alleviating effect on farmers, and provide intervention methods for individual development and happiness acquisition. Therefore, combined with locust prevention and control measures, they provide improvement and regulation for farmers’ anxiety psychology.
