为了明确旱地施用锌肥对冬小麦干物质积累及产量的影响，选用强筋冬小麦品种京9428和普通冬小麦品种轮选987为试材，进行了四个锌肥水平的大田试验。研究结果表明，旱地施用锌肥使小麦干物质积累量显著增多，但施锌肥过量，干物质积累量减少。各产量构成因素受锌影响较小，差异均未达显著水平，但轮选987低锌处理的穗粒数和千粒重最多，中锌处理的穗数最多，高锌处理的穗数、穗粒数、千粒重均减少，最终以低锌和中锌水平产量显著提高，增产达23.8%，与灌溉条件下产量水平相当。京9428施用锌肥使产量有提高的趋势，但处理间差异不显著。京9428不适宜在旱地上种植，旱地上种植轮选987要配以适量锌肥以提高产量，建议锌肥施用量以11.25 kg·hm-2为宜。

英文摘要:

To clear the effect of zinc fertilizer on accumulation of dry matter and yield of winter wheat in dry land, a field experiment with four zinc fertilizer levels was conducted with strong gluten wheat cultivar Jing 9428 and common wheat cultivar Lunxuan 987 as materials. The results showed that zinc fertilizer application could enhance the accumulation of population dry matter in dry land, the amount of accumulation increased significantly. However, excess zinc fertilizer could lower accumulation of dry matter. The effect of zinc fertilizer on yield components was slight, the difference was not significant among treatments. But, in Lunxuan 987, the most grain number per spike and 1000 grain weight appeared in lower zinc level, and spike number per ha was the most in moderate zinc level, however, spike number per ha, grain number per spike and 1000 grain weight were reduced in the highest zinc level, so the yield of Lunxuan 987 increased significantly in lower and morderate zinc level by 23.8%. The yield was equivalent with that in irrigated land. Zinc fertilizer application could increase the yield of Jing 9428, but the difference was not significant among treatments. Zinc fertilizer effect Lunxuan 987 more than that of Jing 9428 in dry land, so Lunxuan 987 and 11.25 kg per hectare zinc fertilizer were recommended to enhance the yield in dry land.
