一、旱蔫成型大丽花需水量大,如未及时补充水分,便会导致幼嫩部分和叶片下垂。解决方法是根据具体情况,适时适量浇水。笔者发现,大丽花在叶片稍蔫时再浇水,有利于生长发育。二、肥蔫大丽花虽喜肥,但忌生冷浓肥。如施用未经腐熟的肥料或肥料浓度过高,便会损伤根系,造成叶片萎蔫甚至整株枯死。遇此情况很难救治,因此施肥务要审慎,薄肥勤施。高温期少施或不施;进入9月可每周施一次液肥,直到花蕾透色为止,肥量依生长状况
First, the drought Dahlia forming large water demand, if not timely replenishment of water, it will lead to the young part of the sagging leaves. The solution is based on the specific circumstances, timely and appropriate watering. I found that dahlia slightly watering the leaves when the water is conducive to growth and development. Second, although fat fertilizer Dahlia hi fat, but avoid cold and fat. Such as the application of uncompounded fertilizer or fertilizer concentration is too high, it will damage the root system, resulting in wilting leaves and even the whole plant died. In this case is difficult to treat, so be careful fertilization, thin fertilizer Qin Shi. Low temperature or low Shi Shi Shi; into the September can be applied once a week liquid fertilizer, flower buds until color, fertilizer according to the growth status
