陕西省富士系苹果晚霜冻指标试验综合方法研究

针对目前陕西省富士系苹果晚霜冻灾害特点及服务需要，依据建立试验目标，确定试验基地、试验时间、人员组成以及技术规范等要素在内的试验思路，建立了包括野外观测试验、人工霜箱试验以及灾后关键生育期调查等方法在内的试验方案，以期通过这种综合试验方法的研究及实践，得到陕西省富士系苹果花蕾和花朵晚霜冻指标体系。该试验方法设计思路是经济林果气象灾害指标试验方案制定领域的首次尝试，可为设计制定其他相关作物气象灾害指标试验方案提供参考和借鉴。

Research on the Experimental Method for the Last Freezing Index of Fuji Apple in Shaanxi Province

For understanding the last freezing features in Fuji apple and meeting the requirements on the services in apple production of Shaanxi province, a comprehensive test program was researched in this paper. The program ideas was based on the order of setting goals, building test locations, determining the time and person, and formulating the technical specifications. The comprehensive test program contained observation test, artificial cream box test and post-critical growth period surveys, and was given a target to get the Fuji apple buds and blooms late freezing index system. This experimental program is the first attempt in meteorological disasters index test program for economic fruit, which will give some provides to other pilot program for other related indicators.
