摘要
为实现科学平衡施肥,提高小麦产量,以优质春小麦永良4号为指示品种,研究配方施肥对小麦产量和产量构成因素的影响。结果表明:以OPT+有机肥处理的小麦产量最高,为9 426.0kg.hm-2,比不施肥(CK)处理的小麦产量增加3 655.5kg.hm-2,增幅为63.3%,比平衡施肥处理OPT的小麦产量增加115.5kg.hm-2,增幅为1.2%。在平衡各微量元素后,适当增施有机肥可显著提高小麦穗粒数和千粒重,其穗粒数为35.6粒,千粒重54.2g,均较其它处理高。
In order to realize scientific balance fertilizer and improve Wheat yield,a field trial was carried out to study the effect of formula fertilization on wheat yield and yield components by using spring wheat Yongliang No. 4 with high-quality as the indicative variety. The results showed that the. highest yield occurred in the treatment of OPT + organic fertilizer. The wheat yield was 9 426. 0 kg·hm^-2, 3 655. 5 kg ·hm^-2 and 115.5 kg·hm^-2 higher than CK(not fertilization) and OPT, the increasing rate were 63.3 % and 1.20%. After balancing various trace elements,the grain number of spike and 1 000-grain weight were significantly increased with increasing organic fertilizer reasonably. And the highest grain number of spike and 1 000-grain weight oc- curred in the treatment of OPT+organic fertilizer,they were respectively 35.6 and 54.2 g.
