摘要
为了探讨不同生育时期喷施不同植物生长调节剂对冬小麦生长发育和产量形成的影响,于2014—2015年在安阳柏庄试验基地进行了小麦生长关键期喷洒吨田宝和磷酸二氢钾的试验。结果表明,喷施吨田宝和磷酸二氢钾可增加小麦株高和单株分蘖数,吨田宝在小麦生长早期喷施效果明显,磷酸二氢钾则相反;冬前分蘖期喷施吨田宝和灌浆期喷施磷酸二氢钾均可增加小麦穗长、总小穗数、穗粒数,进而提高小麦产量和经济系数,且效果最为明显;在小麦生长关键期喷洒吨田宝和磷酸二氢钾的产量均高于喷施清水,最高分别达5104.95,4488.45 kg/hm^2,吨田宝增产效果最好。
The paper aimed to explore the impacts of spraying different growth regulators on the growth and yield formation of winterwheat at different growth stages. An experiment was carried out in Baizhuang county, Anyang from 2014 to 2015, to study the impact ofspraying Duntianbao and potassium dihydrogen phosphate in the key stages of winter. The results showed that the application ofDuntianbao and potassium dihydrogen phosphate could increase the plant height and the tillering number per plant. The effect ofDuntianbao in the early stage of wheat was obvious, and the potassium dihydrogen phosphate was the opposite. The ear length, totalspikelet number and grain number per ear of wheat were enhanced since the spraying of Duntianbao at tillering stage before winter andpotassium dihydrogen phosphate at grain filling stages. It increased wheat yield and economic coefficient, and the effect was significantlyobvious. The yield of spaying Duntianbao and potassium dihydrogen phosphate was higher than that of water in the key period of wheatgrowth, the highest yield was 5 104.95, 4 488.45 kg/hm2, respectively. The effect of Duntianbao is the best.
