冬小麦要夺取高产很重要的一条是培育壮苗,在冬前要有足够的分蘖,以利提高成穗率,达到穗多穗大和提高产量的目的。然而,由于种种原因,我国冬小麦种植区,往往冬前苗不壮,分蘖苗不足,影响产量的提高。近年来,我们应用植物生长延缓剂烯效唑处理小麦种子,发现能培育壮苗,促进根系生长,增加冬前分蘖,有增穗增产效果(表1)。 Winter wheat to capture high yield is very important one is to cultivate strong seedlings, must have enough tillering in winter, in order to improve the rate of ear into a panicle to achieve the purpose of more spikes and increase yield. However, due to various reasons, the planting areas of winter wheat in our country tend to be weak in winter and lack of tillering seedlings, affecting the yield increase. In recent years, we applied the plant growth retardants uniconazole treatment of wheat seeds, found to grow strong seedlings, promote root growth, increase winter tillering, increased ear yield increase (Table 1).
