冬前培育壮苗是小麦稳产保丰收的关键。今年我省小麦单产、总产都创造了历史上最高水平。重要技术措施之一,就是去冬各地都狠狠地抓住了这一条。所谓壮苗,就是冬前单株分蘖多,大蘖多,根系发达,苗子色气好。冬前生长健壮的群体,总茎数要达到预期成穗数的1.5倍左右。只要达到上述标准,来年杆子就壮,穗头就齐,穗子也大,穗粒重也高。 Pre-winter nurturing seedlings is the key to wheat yield stable yield. This year our province wheat yields, total output has created the highest level in history. One of the important technical measures is that this article is severely grasped throughout the winter. The so-called strong seedlings, that is, tillering more than a single plant before winter, more than large tillers, root system developed, seedling good color. Growing robust group before winter, the total number of stems to reach the expected number of spike into 1.5 times. As long as the above criteria are met, the coming year will be strong on the pole. The head of the spike will be the same, the spike will be large, and the weight of the grain will be high.
