To explore suitable water-saving sowing method and irrigation mode of winter wheat in Shanxi Province,multi-point test was conducted to study the effects of sowing methods[furrow sowing(T) and drilling sowing(L)] on yield and its components,nutrient absorption of winter wheat,soil temperature and water content under different irrigation conditions [ no irrigation(W0)and irrigation once at jointing stage (W0)].The results showed that compared with L treatment,aboveground dry weight,effective spikes number and plant height of T treatment significantly increased at the same experimental site;1 000-grain weight of T treatment significantly increased,while spike length and grains number per spike significantly decreased under W0 condition;winter wheat yield of T treatment significantly increased by 2.4%—16.9%. Irrigation could promote nutrient absorption of winter wheat under T treatment. Soil water storage increased by 8.9—19.9 mm under T treatment. In February,soil temperature decreased by 1.43—3.12℃ compared with L treatment,but soil temperature increased by 0.15—1.66℃ under T treatment compared with L treatment in other growth months.In conclusion,furrow sowing increased water storage and soil temperature,improved effective spikes number and yield,and could be used as a water-saving sowing technology for winter wheat production.
