摘要
根据北京地区的气象、草坪和土壤资料,利用由FAO编制的 CROPWAT软件,计算了不同降雨年型北京市草坪灌溉制度,结果为:在干旱年份灌水25次,净灌溉定额447 mm;平水年灌水23次,净灌溉定额411 mm;丰水年灌水19次,净灌溉定额347 mm。
According to the climate, turfgrass and soil data in Beijing, the irrigation schedule of turgrass in Beijing for different typical hydrologic years was calculated with CROPWAT software developed by FAO. The calculated result shows that turgrass need to be irrigated 25 times and total net irrigation quota should be 447mm in dry year, 23 times and 411mm in normal year, 19 times and 347mm in wet year.
