Based on 15 years of flowering observation data, analysis was made on agricultural meteorologi- cal conditions of Osmanthus in Guilin and the results showed that ground tempera- ture, humidity, precipitation, sunshine have significant effects on Osmanthus flores- cence. In forecasting florescence, therefore, it is necessary to take comprehensive consideration of weather conditions and changes in the future, to release Osman- thus flowering forecast as per method of combination of long-term forecasting and short-term forecast.展开更多

Precipitation suitability analysis model before autumn film mulching and crop growth period was simulated to analyze the effective precipitation weather before mulching planting in autumn, and simulations were also made to temperature suitability analysis model during soil preparation and film mulching peri- ods in autumn, the suitability function of optimal sowing time about the soil moisture dynamic changes in autumn in different times, the best water conservation effect in film mulching period at different time after the appearance of effective precipitation, the wind resistance function of film mulching in autumn. All the simulation work was of high referential value to carry out meteorological service and agricultural weather forecast about film mulching in autumn.展开更多
