The invention discloses a preparation method of dedicated cucumber functional
fertilizer containing organic carbon. The dedicated cucumber functional
fertilizer is prepared from the organic carbon,
potassium fulvate and
calcium perphosphate, wherein the weight ratio of the organic carbon, the
potassium fulvate and the
calcium perphosphate is (1 to 6) to (1 to 5) to (0.5 to 1); the organic carbon contains
zinc elements which occupies 0.5 to 2 percent of the organic carbon in weight percentage,
manganese elements which occupies 0.5 to 1 percent of the organic carbon in weight percentage and iron elements which occupies 0.1 to 1 percent of the organic carbon in weight percentage. Through a water-soluble micromolecules-active organic carbon synergist added in the dedicated cucumber functional
fertilizer, organic
nutrient can be directly supplied to plants by skipping the step of
photosynthesis, so that accumulation of
carbohydrate and
nutrient absorption of the plants in cloudy and
rainy weather are ensured; the
nutrient still can be absorbed in the cloudy and
rainy weather, healthy growth is kept, and
plant wither is effectively prevented from happening; in addition, the effect of dedicated cucumber functional fertilizer can be quickly obtained; cucumber growth is vigorous, the characteristics of beautiful, smooth and straight are obtained, the color is invisible green and glossy, the appearance is good, and compared with the usage of contrast fertilizer, the yield is increased by 20 percent or above.
