一、看蔬菜种类 不同的蔬菜,对某一种微量元素敏感程度不同,其需要量也就不一样。施用硼肥增产效果很好的有油菜、白菜、甘蓝型蔬菜、苜蓿、花椰菜、芫菁、莴苣、萝卜等;豆科和十字花蔬菜对钼特别敏感,施用钼肥有很好的增产效果;对锌非常敏感的蔬菜有豆科类、番茄类等,马铃薯、洋葱对锌也较为敏感;需锰较多的有山芋、马铃薯及豆科类蔬菜;莴苣、洋葱、菠菜、胡萝卜对铜较为敏感,需求量也相对多一些;容易缺铁的有马铃薯、花椰菜、甘蓝等;稀土微肥在所有蔬菜上施用都具有显著的增产效果。 First, look at the vegetables of different types of vegetables, a trace of the sensitivity of different elements, their needs are not the same. Application of boron fertilizers have a good effect of rapeseed, cabbage, cabbage-type vegetables, alfalfa, cauliflower, melon, lettuce, radish, etc .; leguminous and cruciferous vegetables are particularly sensitive to molybdenum, molybdenum fertilizer application has a good yield; Vegetables that are very sensitive to zinc are legumes, tomatoes, etc., and potatoes and onions are also more sensitive to zinc; there are potato, potato and leguminous vegetables that require manganese more; lettuce, onion, spinach and carrot are more sensitive to copper , The demand is also relatively more; easily iron deficiency with potatoes, broccoli, cabbage, etc .; rare earth fertilizer application in all vegetables have a significant yield-increasing effect.
