摘要

According to different planting test data, meteorological data, field planting survey and expert interview data in recent years, frost prevention and drought resistance effect of potato under different planting methods were studied using agro-meteorological disaster risk index analysis method. The results showed that the risk index of potato with the full-film planting was small due to good thermal insulation and soil moisture conservation performance. The risk index of potato with half-film planting (flat mulching, ridging planting and furrow planting) was moderate, while that of ridge tillage without mulching, double rows, full of stars and flat planting was large, and their frost prevention and drought resistance effect were poor. It provides support and reference for understanding the frost and drought conditions of potatoes under different planting methods and carrying out insurance weather services for farmers and production managers.
