Abstract:

【Objective】 To study the influence of drip irrigation temperature on the growth and yield of cotton by field warming water irrigation. 【Methods】 the experiment was divided into warming irrigation (ZW) and well water irrigation (CK). The effects of warming irrigation on cotton growth were determined by measuring cotton growth, dry matter accumulation and distribution, nutrient absorption and yield. 【Results】 (1) In warming irrigation conditions, plant height increased significantly in different growing periods, stem diameter increased slightly, leaf area increased significantly during bud and early flowering stage, in addition to full boll stage, the period of specific leaf weight also increased. Warming irrigation could promote the accumulation of biomass in different growth stages and various parts of cotton; (2) warming irrigation had effect on the biomass allocation pattern. The stem weight ratio increased at bud stage and flowering and boll stage, and decreased in the rest stages; (3) The ability of plants to absorb nutrients was increased under warming irrigation condition, and the absorption capacity of the whole cotton to N elements increased by 57.4% (P < 0.01) compared with that of well irrigation. The bell organs P2O5 absorption amount increased 33.0% (P <0.05) compared with well irrigation; the absorption capacity of K20 on roots, stems, leaves and bolls of cotton increased by 23.62%, 53.81%, 62.99%, 33.95%, respectively, compared with well irrigation, stems and leaves increased significantly (P <0.01);(4)Under warming irrigation conditions, the boll number increased by 18.54%, single boll mass decreased 8.86%, cotton yield increased 7.29%. 【Conclusion】 This study suggests that warming irrigation can promote cotton growth, absorption and accumulation of nutrients, biomass and yield, but it is not recommended by warming irrigation in boll stage.

摘要:

【目的】研究田间增温水灌溉下滴灌温度对棉花生长及产量的影响。【方法】设置增温水灌溉(ZW)和井水灌溉试验(CK),测定棉花生长、干物质积累与分配、养分吸收、产量指标,分析增温水灌溉对棉花生长的影响。【结果】增温处理各生育时期株高明显增加,茎粗略有增加,叶面积在蕾期和初花期时显著增加,除盛铃期外,其余时期比叶重也有所增加。增温处理可以促进棉花各生育时期各部位的生物量积累,对生物量分配格局产生影响,蕾期和花铃期茎重比增加,其余降低,初花期与之相反。增温处理下植株对养分吸收的能力增加,整株棉花N吸收量较CK增加57.4%(P<0.01),棉花生殖器官铃中P2O5吸收量较CK增加了33.0%(P<0.05);棉花各器官中K20的吸收量与CK比分别增加了23.62%、53.81%、62.99%、33.95%,茎、叶中增幅明显(P<0.01)。增温水滴灌处理下铃数增加18.54%,单铃重减少8.86%,籽棉产量增加7.29%。【结论】增温水滴灌可以促进棉花生长发育、生物量的积累养分的吸收及产量的形成,但在盛铃期不灌溉增温水。
