Effects of water-saving technology application, disaster type and occurrence stage on disaster area of cotton field

Abstract

The purpose of this paper is to analyze the impact of the application of water-saving technology, types of agricultural disasters and disaster stages on the affected area of cotton field by using the survey data. In this study, bootstrap method was used for quantile regression analysis of cotton disaster area. Four quantiles were selected in the analysis, which was 0.25, 0.5, 0.75 and 0.90. The results were compared with those of OLS regression analysis. The results indicate that the application of drip irrigation water-saving technology and the increase of irrigation expenditure have obvious negative correlation with cotton disaster area. Wind disaster, hail disaster, rain and waterlogging, drought, freezing damage and insect pests have obvious positive effects on the affected area of cotton, and the disease has no significant impact on the affected area of cotton field because of its strong controllability. The results of the study estimated the impact of water-saving technology and disaster types on cotton field disaster area in detail.
