| 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. |
