浙江日报今年4月23日二版,登载本报记者采写的《并非只是黄岩蜜桔……》一文,其中提到:“楚门文旦,苍南四季抛和常山胡柚……这三个品种目前总面积不过两万亩,只占全省柑桔总面积的万分之二。”我以此为“应用题”,做了一项小学生水平的计算:据“题意”,浙江省柑桔总面积为20,000(亩)÷2/10,000=20,000(亩)×10,000/2=100,000,000(亩),即全省柑桔总面积达一亿亩之多!对此,我又做了一道除法,以全省人口4,000万为除数,则浙江人均占有柑桔面积2.5亩,若仅以每亩产量400公斤计,那么全省每人每年占有柑桔1000公斤,平均每天可吃上2.74公斤的柑桔,这岂不足以当饭?! “浙江人均占有柑桔二亩半”,这肯定是在 Zhejiang Daily on April 23 this year, the second edition, published by the reporter wrote “not only Huangyan tangerine ... ...” a paper, which referred to: “Chu Mengyuan, Cangnan seasons throwing and Changshan Huyou ... ... these three varieties The total area of ​​only twenty thousand acres, only the two tenths of the total area of ​​the province’s citrus. ”I use this as the“ application ”, made a calculation of the level of primary school students: According to“ questions ”, citrus The total area is 20,000 (mu) ÷ 2 / 10,000 = 20,000 (mu) × 10,000 / 2 = 100,000,000 (mu), that is, the total area of ​​the province’s citrus reaches more than 100 million mu! Taking the population of 40 million in the province as the divisor, the average per capita area of ​​citrus in Zhejiang is 2.5 mu. If only 400 kg per acre is calculated, the province will have an annual intake of 1,000 kg of citrus per person per day and an average of 2.74 kg of mandarin per day Orange, is it not enough to eat ?! “Zhejiang per capita possession of two and a half acres of citrus,” This is certainly in
