摘　　要：以淮麦30为试验材料,通过不同配方的拌种剂处理小麦种子,研究了不同播种方式下不同配方的拌种剂对小麦生长发育和籽粒产量变化的情况,以期为不同播种方式下选用合适配方的拌种剂,结果表明:零共生套播小麦的出苗期、拔节期、抽穗期、开花期和成熟期较旋耕条播小麦分别提前了11、4、3、3、2 d,生育期比旋耕条播长8 d;在零共生套播模式下,配方1、配方2、配方3处理后的小麦穗粒数较对照分别增加了6.08%、5.47%、3.95%,千粒重较对照分别增加了0.45%、0.45%、0.42%,穗粒重较对照分别增加了6.21%、6.83%、6.21%,有效穗数较对照分别增加了3.69%、4.31%、4.31%,分别增产10.11%、10.76%、10.53%;而在旋耕条播模式下,3种拌种剂处理后的小麦穗粒数较对照分别增加了13.36%、11.99%、10.96%,穗粒重较对照分别增加了12.06%、12.06%、9.93%,千粒重较对照分别增加了1.03%、4.52%、1.49%,有效穗数较对照分别增加了1.34%、1.67%、1.34%,分别增产11.17%、15.75%、11.06%。因此,拌种剂配方2在零共生套种小麦和旋耕条播小麦生产上都有显著增加小麦产量的效果。In this study, Huaimai 30 was used as the test material, and wheat seeds were treated with different formulations of seed dressings to study the effects of different formulations of seed dressings on the growth and development of wheat and the changes of grain yield under different sowing methods, in order to select suitable formulations of seed dressings under different sowing methods. The results showed that the emergence, jointing, heading, flowering and maturity periods of zero symbiosis intercropping wheat were 11, 4, 3, 3 and 2 d earlier than that of rotary tillage and drilled wheat, and the growth period was 8 d longer than rotary tillage and drill sowing. In the zero symbiosis intercropping mode, compared with the control, the number of grains per ear of wheat treated with formula 1, formula 2 and formula 3 increased by 6.08%, 5.47% and 3.95% respectively, and the thousand-grain weight increased by 0.45%, 0.45% and 0.42% respectively. The grain weight per ear increased by 6.21%, 6.83% and 6.21% respectively. The number of effective ears increased by 3.69%, 4.31% and 4.31%, respectively, and the yield increased by 10.11%, 10.76% and 10.53%, respectively. In the rotary tillage and drilling mode, the number of grains per ear of wheat treated with the three seed dressing agents increased by 13.36%, 11.99% and 10.96% respectively. Compared with the control, the grain weight per ear increased by 12.06%, 12.06% and 9.93%, and the thousand-grain weight increased by 1.03%, 4.52% and 1.49%. The number of effective ears increased by 1.34%, 1.67% and 1.34%, and the yield increased by 11.17%, 15.75% and 11.06% respectively. Therefore, the seed dressing formulation 2 had a significant effect on increasing the yield of wheat in the production of zero symbiosis intercropping wheat and rotary tillage and continuous sowing wheat.
