摘要
通过1 a滴灌春小麦小区试验,试验设4 0503、150、2 250 m3/hm2三个水分处理,初步分析了不同灌溉定额下滴灌小麦各生育阶段的耗水特性及对小麦产量的影响。研究结果初步认为,滴灌小麦在新疆具有可行性;滴灌小麦在20～40 cm土层耗水强度最大,耗水高峰期为拔节期和抽穗期,其次是灌浆期、分蘖期和苗期;通过试验数据拟合认为滴灌小麦在灌溉定额3 500 m3/hm2时,产量相对最高,为7 681.2 kg/hm2。
Drip irrigation experiment on wheat in field was carried out to study water demand rules.Three water treatments（4 050、3 150、2 250 m^3/hm^2） ware set to research the water consumption characteristics and impact on yield of wheat at different irrigation amounts.The result enunciation preliminary,the drip irrigation on wheat is practicable in Xinjiang;the biggest water consumption appeared in 20～40 cm soil layer,and the period of the water consumption which gets more and more small from the biggest one by one in order is elongating time,heading stage,grain filling stage,tillering stage,seedling stage.The most yield of drip wheat in the experiment may be 7 681.2 kg/hm^2 when the irrigation quota is 3 500 m^3/hm^2.
