砀山梨栽培历史悠久,砀山酥梨驰名中外。解放以来,全县梨的生产发展很快,现已有梨树80多万株,是解放初的16倍,每年产梨近6000万斤,是解放初的400多倍。目前全县梨园平均亩产约1400斤左右,也出现了亩产15,000斤的高产典型。生产实践表明,砀山梨生产潜力很大,而且也看到梨的产量高低在很大程度上受气象条件的影响。本文初步分析了砀山梨产量与气象条件的关系, Dangshan pear cultivation has a long history, Dangshan pear well-known at home and abroad. Since the liberation, the pear production in the county has developed rapidly. There are now more than 800,000 pear trees, 16 times more than those in the early days of liberation, and nearly 60 million pounds of pears are produced annually, which is more than 400 times of the liberation time. At present, the average yield of pear orchards in the whole county is about 1,400 kilos, and a high-yield typical of 15,000 kilograms per mu has also emerged. Production practice shows that there is great potential for the production of Yanshan pear, but also the pear output is largely affected by the weather conditions. The paper initially analyzed the relationship between the yield and the weather conditions of the pear,
