春季是三麦(小麦、大麦、元麦)一生中生长量最大,吸收养分和水分最多的一个时期。在这个时期里,麦苗的可塑性较大,也是对外界环境条件比较敏感的一个重要时期。所以,只要加强管理,弱苗可以转化为壮苗,迟苗可以迅速发根增蘖,僵苗可以长新叶、出新根,旺长苗也可以得到控制,处于动摇状态的分蘖可以争取成穗;同样,如果措施不当,原来长势较好的一、二类苗也可能中期衰败,长势较弱。长江
Spring is the three wheat (wheat, barley, wheat) the largest growth of life, absorption of nutrients and water a period of the most. During this period, wheat seedlings are more plastic and are also an important period that is sensitive to the external environmental conditions. Therefore, as long as the strengthening of management, weak seedlings can be transformed into strong seedling, late seedlings can quickly root tillering, stiff seedlings can be long new leaves, a new root, seedlings can also be controlled, in tilted tiller can fight for Similarly, if the measures are not properly implemented, the first and second class seedlings, which grew better, may also fail in the medium term and grow more weakly.
