为实现小麦增产稳收,除打好播种基础外,还必须加强冬前麦田管理,以充分利用冬前积温,在全苗匀苗的基础上,促根、增蘖、促弱控旺,培育壮苗。一、查苗、补苗与疏苗。麦苗出齐后,应及时检查,对缺苗地段,一是补种。补种前用同一品种按1公斤种子1公斤水的比例浸种—天,捞出晾1—2小时后补种。也可用500倍磷酸二氢钾浸种12小时后播种。如果插种偏晚,可将浸过的麦种催芽后补种,能提早2—3天出苗。二是不能及时补种的,应在分蘖始期移苗补栽。移栽后及时浇水,以保证成活。播种不均匀的要在三叶期进行疏苗,移密补稀,以保证苗全、苗匀。
In addition to lay a good foundation for sowing wheat, it is also necessary to strengthen the management of winter wheat fields in order to make full use of winter accumulated temperature. On the basis of the whole seedlings, root growth, tillering, weakening, Strong seedlings. First, check Miao, Miao Miao and sparse seedlings. Emergence of wheat seedlings, should be promptly checked, the lack of lot, one replanting. Replanting with the same species by 1 kg of seed 1 kg of water soaking - days, remove and dry 1-2 hours after replanting. Can also be 500 times potassium dihydrogen phosphate soaking 12 hours after sowing. If you planted late, can be soaked wheat seed germination after replanting, can be 2-3 days earlier emergence. Second, can not replant in time, should be the beginning of tillering seedling replanting. Watering timely after transplanting to ensure survival. Sowing non-uniform to the sprouting in the three-leaf stage, moving dense make up dilute, in order to ensure full seedlings, Miao uniform.
