【摘要】 根据近 3 0年资料 ,对宝鸡渭北旱原农业气候资源、农业气象灾害发生规律进行了系统的分析 ,结论是 :光能资源丰富 ,光合生产潜力较大 ,热量资源充足 ,有利于玉米等喜温作物的种植。光照充足 ,温差大 ,对作物和瓜果产量和质量的提高有利 ,雨量季节分布不均 ,降水变率大。干旱、冰雹、连阴雨、暴雨、大风、干热风和霜冻是该区农业的主要气象灾害 ,特别是春夏连旱 ,严重影响农业生产 ,所以 ,要充分利用光能资源优势 ,发展灌溉和科学用水 ,提高水的利用率。更多还原

【Abstract】 With plentiful solar energy and heat resource, the photosynthetic production potentiality being great, the Arid plain, North of Weihe River of Baoji, is adequate to plant corn, winter wheat, etc. Plentiful light and the great temperature difference are in favorable to the yield increase and the good quality of melons and fruits. irrigation distributes unevenly in four seasons. irrigation variability is great. The Aridity, hailstone, rainy weather for several days, rainstorm, great wind, dry and warm wind and frog are the main disasters. Especially the continuous Aridity of Spring and Summer affects the agricultural production severely.更多还原
