播种方式对不同品种小麦产量和品质的影响

研究不同播种方式对不同品种小麦产量和品质的影响，为小麦高产高效栽培提供参考。采用二因素随机区组设计，播种方式为匀播（A1）和常规条播（A2），小麦品种为衡观35(B1)、邯6172(B2)、轮选103(B3)和石麦25(B4)。结果表明，2种播种方式对植株性状影响差异显著，条播的株高和穗粒数均显著高于匀播，匀播的产量、穗数和千粒重均显著高于条播，其中匀播处理的产量比条播提高4.42%。播种方式对小麦的容重、面筋指数、出粉率和14%吸水率有显著影响，匀播处理的小麦出粉率比条播高2.02个百分点。条播处理下石麦25的产量最高，衡观35的磨粉品质较好；匀播处理下衡观35、邯6172和轮选103的产量均较高，邯6172的粉质指标较好。

Effects of Sowing Methods on Yield and Quality of Different Varieties of Wheat

The study of the effects of different sowing methods on the yield and quality of different varieties provides an effective reference for high-yield and high-efficiency wheat cultivation measures. This experiment used a two-factor randomized block design. The sowing methods were uniform sowing (A1) and conventional drill seeding (A2). The wheat varieties were Hengguan 35 (B1), Han 6172 (B2), Lunxuan 103 (B3) and Shimai 25 (B4). The results showed that, the two sowing methods had significant differences in influence on plant traits. The plant height and number of grains per spike of drill sowing were significantly higher than that of uniform sowing. The yield, spike number and 1000-grain weight of uniform sowing were significantly higher than those of drill sowing, and the yield of uniform sowing treatment was 4.42% higher than that of drill sowing treatment. The sowing method had a significant effects on the bulk weight, hardness index, yield rate and 14% water absorption. The bulk weight of wheat under uniform sowing was 2.02 percentage points higher than that of drill sowing. Shimai 25 had the highest yield and Hengguan 35 had better flour quality. The yields of Hengguan 35, Han 6172 and Lunxuan 103 under uniform sowing were higher, and the farinogram quality index of Han 6172 was better.
