摘要:

【背景】提高水分利用效率有利于小麦的可持续生产。垄沟种植和测墒补灌技术均可以显著提高作物水分利用效率。但二者结合能否起到良好的节水效果,从而提升小麦水分利用效率,目前尚不明确。【目的】探索垄沟种植结合测墒补灌对小麦群体、产量和水分利用效率的影响。【方法】进行了为期两年的田间试验,冬小麦品种选用西农20,采用沟播(P1)、垄播(P2)和平作(P3)3种种植方式,结合0—40 cm土层补灌至田间持水量(S40)、0—60 cm土层补灌至田间持水量(S60)和传统漫灌作为对照(SCK)3种灌溉处理。通过测定土壤含水量、冬小麦茎蘖动态、干物质积累量、产量及其构成因素,并计算农田耗水总量、降水利用效率、灌溉水利用效率和总耗水利用效率、边行指数及经济效益来探究种植方式和测墒补灌技术对冬小麦生长发育、产量、水分利用效率和经济效益的影响。【结果】沟播种植方式配合60 cm土层测墒补灌(P1S60)处理的土壤含水量、小麦茎蘖数及干物质积累量与平作传统漫灌处理(P3SCK)无显著差异,并且沟播种植方式利用边际效应提高边行冬小麦的穗数和穗粒数,保证小麦产量不降低的同时,结合0—60 cm土层测墒补灌可以节约灌溉水34.5%,降低农田耗水总量10.8%,使灌溉水利用效率(IWUE)和水分利用效率(WUE)分别提高79.5%和14.7%(两年平均值)。与平作传统漫灌(P3SCK)处理相比,沟播配合0—60 cm土层测墒补灌(P1S60)处理总收入提高3.2%,具有较高的经济潜力。【结论】在综合考虑水资源利用效率、作物产量和收益潜力的情况下,采用沟播种植、0—60 cm土层补水至田间持水量为关中灌区较好的种植模式。

Abstract:

【Background】Improving water use efficiency is beneficial for the sustainable production of wheat. Both ridge and furrow planting and soil moisture-based supplemental irrigation techniques can significantly enhance crop water use efficiency. However, whether the combination of these two approaches can achieve effective water-saving outcomes and further improve the water use efficiency of wheat remains unclear. 【Objective】This study aimed to explore the effects of ridge-furrow planting combined with soil moisture measurement and supplementary irrigation on the population, yield and water use efficiency of wheat. 【Method】In this study, a two-year field experiment was conducted. The winter wheat variety Xinong 20 was selected, and three planting methods of furrow sowing (P1), ridge sowing (P2) and flat planting (P3) were used. Three irrigation treatments were set up, including supplementary irrigation of soil moisture content in the 0-40 cm soil layer to field water holding capacity (S40), supplementary irrigation of soil moisture content in the 0-60 cm soil layer to field water holding capacity (S60), and traditional flood irrigation as the control irrigation (SCK). By measuring the soil moisture content, the dynamics of tillers of winter wheat, dry matter accumulation, yield and its constituent factors, and calculating the total water consumption of farmland, precipitation use efficiency, irrigation water use efficiency, total water consumption use efficiency, border row index and economic benefits, the effects of ridge-furrow planting and soil moisture measurement-based supplementary irrigation techniques on the growth and development, yield, water use efficiency and economic benefits of winter wheat were explored. 【Result】The furrow sowing combined with soil moisture measurement and supplementary irrigation at 60 cm depth (P1S60) maintained similar soil water content, tillers number, and dry matter accumulation as the flat planting with traditional flood irrigation (P3SCK). By leveraging the marginal effect, furrow sowing increased spike number and grains per spike of border-row winter wheat. For ensuring stable wheat yield, P1S60 saved 34.5% of irrigation water and reduced total farmland water consumption by 10.8%. It also boosted irrigation water use efficiency (IWUE) by 79.5% and water use efficiency (WUE) by 14.7% (two-year average). Compared with P3SCK, P1S60 raised total income by 3.2%, indicating high economic viability. 【Conclusion】Considering the utilization efficiency of water resources, yield and income potential, P1S60 was a planting method with high potential in Guanzhong irrigation area.
