一、因地因苗,分类管理1.以促为主,搞好三类麦田的肥水管理对于受旱严重、分蘖节处于干土层中、次生根长不出来或很短的三类麦田。一是及早动手,要浇好“保苗水”。当日平均气温稳定在3℃、白天浇水后能较快渗下时,就要抓紧浇水保苗,时间越早越好。浇水时要按照旱情先重后轻,先砂土地后黏土地,先弱苗后壮苗的原则,小水灌溉,避免大水漫灌,地表积水,出现夜间地面结冰现象。二是浇水后地表墒情适宜时要及时划锄,破除板结,疏松土壤,保墒增温,促进根系和分蘖生
First, because of seedlings, classification management 1. To promote the main three kinds of wheat fields to improve fertilizer and water management For severely affected, tillering section in the dry soil layer, the secondary roots grow out or short three types of wheat fields. First, start early, to pour good “Paul Miao water ”. On the day the average temperature was stable at 3 ℃, the water can be infiltrated quickly after daytime, we must pay close attention to watering seedlings, the sooner the better. Watering should be carried out according to the first heavy drought, the first clay after clay, weak seedlings after the principle of strong seedlings, water irrigation, to avoid flood irrigation, surface water, the phenomenon of ground icing at night. Second, the surface moisture after watering appropriate time to plan hoe, break the compaction, soil loosening, warming soil moisture and promote root and tillering
