根据对监测点及全区小麦苗情的调查,小麦进入越冬期以来,旺苗面积占20%,弱苗田块几乎没有,部分田块杂草多,病虫害越冬基数大,给春季麦苗病虫害大面积发生埋下隐患。还有部分田块出现轻微冻害,春季管理要结合受害田块的情况,及时进行化学除草,防治病虫害的发生,一般田块不施返青肥,根据苗情追施拔节孕穗肥,以满足小麦生长及灌浆期产量形成的营养需求。
According to the monitoring points and the survey of wheat seedlings in the region, wheat into the wintering period, Wang seedlings area accounted for 20%, scarce seedlings plots almost no weeds in some plots, pests and diseases overwinter base, to the spring wheat seedlings pests and diseases large area Occurred hidden dangers. There are some plots of frost damage, spring management should be combined with the case of damaged plots, chemical weeding in time to prevent the occurrence of pests and diseases, the general plots do not apply green manure, according to the seedlings jointing booting section booting fat to meet the growth of wheat And the nutritional needs of the formation of grain yield.
