本试验是在小麦新品种济宁16号通过省审后,所做的一项高产配套栽培技术研究。本试验用等量标准氮肥,做了3种不同处理追施。结果为:以标准氮肥的50%作为底肥,50%作为拔节肥,小麦群体变化最合理;以标准氮肥50%作为底肥,50%作为拔节肥追施,小麦增产达极显著水平,此处理下的小麦产量比以标准氮肥的50%作为底肥,50%作为起身肥处理下的产量增产显著;以标准氮肥50%作为底肥,50%作为拔节肥的小麦灌浆时间最长,千粒重最大;以标准氮肥50%作为底肥,40%作为起身肥,10%作为挑旗肥为处理的倒伏最严重,以标准氮肥50%作为底肥,50%作为拔节肥的小麦倒伏最轻。
This experiment is a high-yielding cultivation technology research done after the wheat new variety Jining passed the provincial trial. This experiment with the same amount of standard nitrogen fertilizer, done 3 different top-dressing. The results were as follows: 50% of standard nitrogen fertilizer was used as base fertilizer and 50% was used as jointing fertilizer, and the change of wheat population was the most reasonable. With 50% of standard nitrogen fertilizer as base fertilizer and 50% of topdressing fertilizer as top dressing, wheat yield increased significantly Of wheat yield was significantly higher than 50% of the standard nitrogen fertilizer and 50% of the yield as a fattening fertilizer. 50% of the standard nitrogen fertilizer was used as the base fertilizer and 50% of the wheat as the jointing fertilizer had the longest filling time and the 1000-grain weight. 50% nitrogen fertilizer as base fertilizer, 40% as a fattening, 10% as a flag-bearing fertilizer for the treatment of lodging the most serious, with 50% of standard nitrogen fertilizer as the base fertilizer, 50% as the jointing fertilizer wheat lightest lodging.
