由于连年种植香蕉 ,而且施肥多以化肥为主 ,缺乏有机肥 ,土壤酸度提高 ,土壤中供香蕉吸收的大量元素逐渐减少 ,地力明显下降。香蕉营养生长速度缓慢 ,结果时间推迟 ,果实发育迟缓 ,抗寒力下降 ,受冻严重 ,施肥量逐年增加树势却逐渐减弱。为此 ,特提出以下几条克服措施。1 套种
As successive years of planting bananas, and fertilizers and more fertilizer-based, the lack of organic manure, soil acidity increased, a large number of elements in the soil for banana absorption decreased, significantly decreased soil fertility. Banana vegetative growth is slow, the results of the time delay, fruit retardation, cold resistance decreased, suffered severe freezing, the amount of fertilizer increased year by year, gradually reduced. To this end, special proposed the following measures to overcome. 1 sets of species
