探讨了高产栽培的肥水条件下 ,在小麦拔节后期施用多种植物生长物质对倒伏、穗花发育以及产量的影响。结果表明 :在对照倒伏严重的地块 ,喷施麦特 (环己烷三酮类植物生长延缓剂 )处理可极显著抑制穗下、倒 2和倒 3节间伸长 ,全田未发生倒伏且穗花发育正常 ,较对照增产33.1% ;多效唑 (三唑类植物生长延缓剂 )处理在晚施条件下抗倒伏效果降低 ,穗花发育明显受到抑制 ;天宝 (增产胺类 )、芸薹素 (芸薹素内酯类 )、爱多收 (复硝钾类 )和起土产 (壳多糖类 )处理倒伏程度略轻于对照 ,而单株穗数和穗粒数显著高于对照
The effects of applying a variety of plant growth substances on the development of lodging and spike flower and the yield of wheat at the late jointing stage were studied under the condition of high-yielding fertilizer and water. The results showed that spraying maitre (cyclohexanone-based plant growth retardants) could significantly and significantly inhibit the elongation at the ear, down 2 and down 3 in the control plots, The treatment of paclobutrazol (plant growth retarded by triazole) reduced the lodging resistance and the development of flower spikelets was obviously inhibited. The effects of Tribulus (increased production of amines), Brassica The contents of spikes and spikelets per spike were significantly higher than those of the control
