于2008—2010年通过田间试验,以高产中筋冬小麦品种济麦22为材料,设等行距平作、宽窄行平作、沟播3种种植方式,每种种植方式下设不灌水(W0)、拔节水(W1)、拔节水+开花水(W2)、拔节水+开花水+灌浆水(W3)4种灌溉处理(每次灌水量为60 mm),研究不同灌溉和种植方式对冬小麦耗水特性及干物质积累与分配规律的影响.结果表明:随灌水量的增加,3种植方式下农田总耗水量均增加,灌水量占总耗水量的比例也增加,而土壤贮水消耗量及其占总耗水量的比例显著降低;与W0处理相比,各灌水处理提高了开花后干物质的积累量、小麦籽粒产量,而水分利用效率(WUE)降低.同一灌溉条件下,与其他两种种植方式相比,沟播方式土壤贮水量消耗比例、籽粒产量和WUE均较高.综合考虑小麦的籽粒产量和WUE,沟播结合灌拔节水+开花水是华北平原冬麦区较适宜的节水种植方式.
In 2008-2010, three high-yielding mid-winter wheat cultivars, Jimai 22, were planted in field trials with three rows of horizontal and horizontal rows for planting and furrow planting. Each planting mode consisted of irrigation without irrigation (W0) (W1), jointing water + flowering water (W2), jointing water + flowering water + grouting water (W3) were used to study the effects of different irrigation and planting methods on water consumption characteristics of winter wheat Dry matter accumulation and distribution.The results showed that with the increase of irrigation amount, the total water consumption of farmland increased under the three planting modes, and the proportion of irrigation water to the total water consumption also increased, while the soil water consumption and its total Compared with W0 treatment, the irrigation treatment increased the accumulation of dry matter after flowering and the grain yield of wheat, but the water use efficiency (WUE) decreased.Under the same irrigation conditions, compared with the other two planting methods Compared with the proportion of soil water consumption, the grain yield and WUE were all higher in the furrow-planting ways.Considering the grain yield and WUE of wheat, the combination of furrow-sowing and irrigation with water and irrigation was the more suitable water-saving planting in the winter wheat region of North China Plain the way.
