不同灌溉方式对冬小麦生长发育及水分利用效率的影响
Effect of Irrigation Methods on Growth and Water Use Efficiency of Winter Wheat
摘要
Abstract
A field plot experiment was conducted to investigate the efficacy ofdifferent irrigation methods in achieving high yield and water use efficiency of winter wheat in south of Shanxi Province. We examined micro-sprinkler irrigation (MSI), surface drip irrigation (SDI) and flooding irrigation (CK). The soil moisture dynamics, plant growth traits, yield and water use efficiency under each irrigation were measured. In the sprinkler and sur-face drip irrigation, we watered the crop at wintering period (9 December 2015), elongation stage (1 April 2016) and grain-filling stage (20 May 2016), each with 600 m3/hm2 of water, while in the flooding irrigation, we wa-tered the crop twice, one at the wintering stage and the other one at the elongation stage, each with 2250 m3/hm2 of water. The results showed that there was no noticeable difference between soil moisture content in the 0~100 cm of soil during the wintering period under different irrigations, and that the difference emerged at the filling stage with the moisture content in 0~80 cm of soil decreasing in the order of SDI>MSI>CK. The MSI and DSI treatment met the demand of crop for water at the filling stage. Compared with CK, MSI and SDI increased the tillering number per plant and population culm number, promoting population growth, mature spike number, spike grain number and thousand-seed weight; these led to an increase in yield. Compared with CK, MSI in-creased spike grain number and thousand-seed weight by 16.54%and 5.21%respectively, and SDI increased by 10%and 11.78%respectively. MSI and SDI increased yield by 2.79%and 3.35%, while reduced water consump-tion by 43.88%and 41.64%respectively, leading toan increase in water use efficiency by 83.15%and 77.09%re-spectively. In summary, micro-sprinkler and surface drip irrigationscan save water without scarifying winter wheat yield in southern Shanxi Province.关键词
