应用国家基本站历年气象资料、1985~1986年地膜玉米秋季分期覆膜播种、10月份有效降水出现后分期覆膜播种、吹风机风力模拟实验资料等研究宁夏西吉秋覆膜种植的农业气象条件。模拟了秋季覆膜前与作物生育期降水适宜度分析模型,对秋季覆膜前有效降水天气形势进行了分析,模拟了秋季整地覆膜期温度适宜度模型、不同覆膜时间水分动态变化最佳播种期适宜度函数、出现有效降水后不同时间最佳覆膜期保水效益、秋覆膜的抗风性能函数,这些工作对开展秋覆膜气象服务及农用天气预报具有较高的参考价值。
The meteorological conditions of Xijie autumn planting in Ningxia were studied by meteorological data of national basic stations, planting seasons of mulching corn in autumn from 1985 to 1986, post-seeding mulching with effective precipitation in October, and wind simulation data of hair dryer. Simulating autumn precipitation pre-crop and crop growth period precipitation suitability analysis model, autumn pre-filming pre-precipitation weather conditions were analyzed to simulate the autumn land preparation temperature model of temperature suitability, the dynamic changes of moisture content of different film mulching time best Sowing period suitability function, the optimal water-holding benefit at different time after effective precipitation, and the wind-resistant performance function of autumn mulching film, all of which have high reference value for carrying out autumn-covered meteorological service and agricultural weather forecasting.
