一、叶面肥及其增产作用叶面肥是一种有特色的新型肥料,叶面肥喷施在作物叶片上,使作物通过叶片吸收养分,能收到意想不到的增产效果。研究证明,植物的叶片、叶柄、茎秆也是植物吸收养分的器官,植物从叶片吸收养分具有比根系吸收养分更独特的效果。第一、叶片吸收养分比根系吸收养分速度快、利用率高,在一般情况下,尿素施于土壤要经过四、五天才能见效,而叶面喷施 First, the role of foliar fertilizer and its production Foliar fertilizer is a unique new type of fertilizer, foliar spray applied to the crop leaves, so that crops absorb nutrients through the leaves, can receive unexpected yield increase. Studies have shown that plant leaves, petioles and stems are also organs that plants absorb nutrients. Plants absorb nutrients from leaves more specifically than root nutrients. First, the leaves absorb nutrients faster than the root absorption of nutrients, high utilization, under normal circumstances, urea applied to the soil after four or five days to bear fruit, and foliar spray
