| 摘 要： | 冻害是影响五寨甜糯玉米生长发育的主要气象灾害性之一,防御冻害最为经济有效的措施就是了解五寨低温冻害特征,选择最佳播种和采收时间,规避冻害风险。本文利用五寨县64a气温、10cm地温、霜日等气象资料和近10a的冻害资料,采用数理统计、概率统计、Excel分析等方法,分析研究了低温冻害对五寨县甜糯玉米全生育期的影响。研究表明：五寨县甜糯玉米生育期内,春季冻害危害风险较高,秋季冻害危害风险较低。甜糯玉米苗期至三叶期,冻害危害风险最高的时段为4月25日至5月15日。甜糯玉米采收期,冻害危害风险最高的为9月下旬。针对研究结果,提出相应的防御对策,旨在为科学合理种植甜糯玉米提供技术支撑。

| Abstract: | freezing injury is one of the main meteorological disasters affecting the growth and development of Wuzhai sweet waxy corn. The most economical and effective measure to prevent freezing injury is to understand the characteristics of Wuzhai low-temperature freezing injury, select the best sowing and harvesting time, and avoid the risk of freezing injury. Based on the meteorological data of 64a temperature, 10cm ground temperature and frost day in Wuzhai county and the data of freezing injury in recent 10 years, the effects of low temperature freezing injury on the whole growth period of sweet waxy corn in Wuzhai county were analyzed and studied by using the methods of mathematical statistics, probability statistics and excel analysis. The results showed that during the growth period of sweet waxy maize in Wuzhai County, the risk of freezing injury was higher in spring and lower in autumn. From seedling stage to three leaf stage of sweet waxy maize, the period with the highest risk of freezing injury is from April 25 to May 15. In the harvest period of sweet waxy corn, the risk of freezing injury is the highest in late September. According to the research results, the corresponding defense countermeasures are put forward in order to provide technical support for scientific and rational planting of sweet and waxy corn. |
