小麦适期播种,是争取冬前壮苗的关键,获得小麦高产的基础。适期播种的小麦,能在进入越冬前“扎好根,盘好根”,麦苗具有良好的根系和一定数量的分蘖,健壮生长,安全越冬。生产实践证明,一般冬前分蘖,尤其是大分蘖成穗率高,冬前小分蘖以及春后分蘖成穗率低。适期播种,争取冬前多分蘖,长壮蘖,是增加穗数,夺取小麦高产的重要措施。去年,我县小麦播种期从9月17日开始到10月18日,共有32天,大多集中在9月22日至10月12日这21天当中。根据不同播期的3,382.2亩麦田调查来看,10月1日以前播种的,每亩总茎数在77万以上,平均单株分蘖1.9个以上,10月2日以后播种的,总茎数在43万以下。据近二年气象资料分析,11月16日后,气 Sowing wheat is suitable for winning the winter seedlings, the key to obtain the basis for high-yield wheat. Wheat sowing season, before entering the winter before the “tie root, pan good roots,” wheat seedlings have a good root and a certain number of tillers, robust growth, safe wintering. Production practice has proved that, in general, winter tillers, especially large tillers into the ear, small tillers before winter and tiller tillering rate is low. Appropriate sowing for winter tillers, long and strong tillers, is to increase the number of spikes, an important measure to seize the high yield of wheat. Last year, the county’s wheat sowing period started from September 17 to October 18 for a total of 32 days, mostly in the 21 days between September 22 and October 12. According to different sowing date of 3,382.2 acres of wheat field survey point of view, October 1 before sowing, the total number of stalks per acre in more than 770000, an average of more than 1.9 tillers per plant, October 2 after sowing, the total number of stems in 430,000 or less. According to the past two years of meteorological data analysis, November 16, gas
