“893”作物增产灵是一种用天然植物作原料,研制成含有作物需要的N、P、K和微量等12种元素的高效复合液肥。通过稀释配成不同浓度,喷酒于作物茎叶上,能在较短时间内被摄取90％的营养,余下的由根部吸收。一、材料与试验液肥配制:水稻一般以0.1％浓度,即1000ppm,每次亩用原液75毫升,兑水75公斤喷施。蔬菜浓度多用0.075％,即750ppm,每次亩用原液37.5毫升,兑水50公斤喷施。
“893” Zenglingling is a kind of high-efficiency compound liquid fertilizer with 12 kinds of elements such as N, P, K and trace which are needed by crops. Diluted to different concentrations, spray on the stems and leaves of crops, in a relatively short period of time is 90% of the intake of nutrients, the remaining absorbed by the roots. First, the material and test Preparation of liquid fertilizer: rice is generally 0.1% concentration, that is 1000ppm, 75ml per mu stock solution, watered 75 kg spray. Multi-purpose vegetable concentration of 0.075%, that is, 750ppm, 37.5 ml per mu stock solution, watered 50 kg spray.
