[ Method ] From climate resources, relationships between meteorological conditions (tem- perature, water and sunshine, etc. ) and growth of the organic crops in Boshan District of Shandong were analyzed. 5-year development plan was put forward. Influences of the main meteorological disasters in growth process of the organic crops were analyzed. Moreover, corresponding de- fense countermeasures were put forward. [ Result] Due to monsoon influence in Boshan, rain and heat were in same season. Sunshine, heat and water coordinated well, and effectivity of the agricultural climate resources was higher. Qualities of the soil and water were good. Vegetation was complete. These conditions were all favorable for developing organic agricultural region. But the precipitation variability was big, which limited effec- tive utilizations of the sunshine and heat resources at different degrees. Meanwhile, in organic crops growth season when sunshine, heat and water were sufficient, meteorological disasters happened frequently. [ Conclusion] We should accelerate construction of the small water conservancy facil- ities, making rainstorm and flood as resources, and realizing timely watering. In addition, we ought to accelerate construction of the industrialized organic a clriculture to improve agricultural benefit.展开更多
