去冬持续干旱低温,对越冬麦苗起了明显的控上促下作用。因而,麦根发得多,扎得深,为冬壮春发提供了一个良好的条件。但事物总是一分为二的,由于在于冻条件下,麦苗体内的营养运转和利用受到阻碍,根系的吸肥供肥能力削弱,从而影响地上部分的生长,致使麦苗发棵晚、分蘖慢、苗数少、营养体小,特别是晚种的稻茬麦,未能带蘖过冬,到立春尚未见分蘖,对攻多穗,争大穗十分不利。目前,气温不断上升,麦苗生
Last winter drought continued low temperature, the overwintering wheat seedlings played a significant role in promoting the next role. Thus, McGannhaal hair more deeply, for the winter strong spring provides a good condition. However, things are always divided into two, due to the freezing conditions, malt body nutrition and utilization are hindered, the root system of weakening the role of fertilizer and fat supply, thus affecting the growth of the ground above, resulting in wheat seedling trees, tillers slow , The number of seedlings is small, small body of nutrients, especially the late rice varieties of wheat, failed to take the winter tiller, tillering to the beginning of spring has yet to see, more attack on the spike, fight spike is very negative. At present, the temperature is rising, wheat Miao students
