冬小麦采用滴灌方式灌溉追肥,强化其肥水管理,充分运用配方施肥技术和病虫害综合防治技术,加强高产稳产农田建设,可全面提升粮食综合生产能力,确保粮食安全。一、滴灌优点1.滴灌是一种可控制的局部灌溉,可适时适量灌水,在冬小麦生长期内,比地面灌溉省水40%~50%。2.肥料随滴灌水流直接送达作物根系部位,易被作物根系吸收,提高肥料利用率,在生长期内平均可省肥20%左右。3.由埋入地下及地面移动的输水管道,代替大水 Winter wheat drip irrigation top dressing, strengthen its fertilizer and water management, make full use of formula fertilization techniques and integrated pest management techniques to strengthen high-yield farmland construction, can comprehensively enhance the comprehensive production capacity of grain to ensure food security. First, the advantages of drip irrigation 1. Drip irrigation is a controlled local irrigation, timely irrigation, in the winter wheat growing period, than the ground irrigation water 40% to 50%. 2. Fertilizer with drip irrigation directly to the root parts of the crop, easily absorbed by crop roots, improve fertilizer utilization, the average growth period of about 20% fertilizer. 3. Instead of floods, water pipelines that are buried underground and on the ground should be replaced
