Abstract

The invention discloses a rape foliar fertilizer, comprising the components according to the following proportion: water serving as a carrier, 280-350kg/m<3> urea, 220-250kg/m<3> potassium dihydrogen phosphate, 100-120kg/m<3> boric acid, 60-80kg/m<3> potassium sulfate and 50-80kg/m<3> polyaspartic acid. A method for preparing the rape foliar fertilizer comprises the following steps: adding urea into water, stirring at 80-120r/min to prepare a water solution at 30-35 DEG C, and adding the potassium dihydrogen phosphate, the potassium sulfate and the polyaspartic acid to prepare a solution a; and adding the boric acid into boiling water under shaking for dissolution, adding the dissolved boric acid into the solution a, blending uniformly, and regulating a pH value to be 6.5-7.5 to obtain the rape foliar fertilizer.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a rape leaf fertilizer. Background technique [0002] my country's rapeseed is distributed all over the country and is the fifth largest crop in my country. Its cultivated area and total output both occupy the first place in the world. It has a long growth period and a large amount of fertilizer. There are many; but the large amount of chemical fertilizer is a kind of pollution to the environment, and the low utilization rate of soil fertilization is also a waste; [0003] Foliar fertilizer is a type of fertilizer that applies nutrients to the surface of crop leaves and exerts basic functions through the absorption of leaves. The leaves of plants have upper and lower layers of epidermis, which are composed of epidermal cells. There are cuticles and waxes on the outside of the upper epidermal cells. It can protect the mesophyll cells under the epidermis to perform photosynthesis and respiration fun...
