两年度在池栽防雨条件下研究了10个灌水处理对小麦某些生理特性、产量构成因素及产量的影响,分析了灌溉效益,提出小麦生育前、中期适度灌溉,在保证适宜亩穗数和幼穗正常发育的前提下,抑制营养生长过旺,后期补充灌溉,促进根系生长,延缓功能叶片衰老,保证穗粒数和粒重,是确立高产高效灌水方案的原则。文中还讨论了高产高效低定额灌溉的优化方案。在浇底墒水的前提下,根据降水情况,浇两水以拔节水和挑旗水或挑旗水和灌浆水为宜。
The effects of 10 irrigation treatments on some physiological characteristics, yield components and yield of wheat were studied in the two years under the conditions of pool planting and rain-proofing. The irrigation benefit was analyzed, and the appropriate irrigation was proposed before and during wheat growth. Under the premise of the normal development of panicle and panicle, it is the principle of establishing high-yield and high-efficiency irrigation scheme to restrain vegetative growth excessively, supplement irrigation later, promote root growth, delay functional leaf senescence and ensure grain number and grain weight. The article also discusses the optimization of high yield, high efficiency and low fixed irrigation. In the pouring under the premise of water, according to the precipitation, pouring two water to pull water and pick the flag or flag water and grouting water is appropriate.
