针对小麦高产田肥水投入量偏大及劳动成本逐年提高制约高产高效的状况,2014年北京市开展了小麦资源高效利用技术研究和示范推广工作,取得了显著成效。一是高产点产量创历年最高,达10 227.0kg/hm2,再创北京小麦单产纪录。二是资源利用率显著提高,高产点平均灌水2 920.5t/hm2,较上年减少307.5t/hm2,灌水和耗水生产率分别比上年提高38.1%和26.7%;平均投入纯养分511.5kg/hm2,较去年减少34.5kg/hm2,减幅6.3%;养分生产率15.4kg/kg,较上年提高3.2kg/kg,增幅26.2%。三是用工减少,劳动生产率明显提高,高产点用工较上年减少3个/hm2,劳动生产率较上年增加99.6kg/工,增幅38.2%。
In view of the large input of fertilizer and high labor productivity of wheat and the rising labor costs year after year, the status of high yield and high efficiency is restricted. In 2014, Beijing carried out research and demonstration and promotion of the efficient utilization of wheat resources and achieved remarkable results. First, high-yield point record high in the calendar year, reaching 10 227.0kg / hm2, a record Beijing wheat yield. Second, the utilization rate of resources was significantly increased. The average high-yielding irrigation was 2 920.5 t / hm2, a decrease of 307.5 t / hm2 from the previous year. The productivity of irrigation and water consumption increased by 38.1% and 26.7% respectively over the previous year. The average input of pure nutrients was 511.5 kg / hm2, a decrease of 34.5kg / hm2 over the previous year, a decrease of 6.3%. Nutrient productivity was 15.4kg / kg, up by 3.2kg / kg from the previous year, an increase of 26.2%. Third, the reduction in labor force, labor productivity was significantly improved, high-yielding point of employment decreased by 3 / hm2 over the previous year, labor productivity increased 99.6kg / worker over the previous year, an increase of 38.2%.
