Rare earth plant growth regulator

Abstract

The invention belongs to the technical field of rare earth application, and particularly relates to a rare earth plant growth regulator. The rare earth plant growth regulator is prepared from the following components in percentage by weight: 13% to 16% of rare earth, 70% to 75% of urea, 0.5% to 0.8% of sucrose fatty acid ester, 2% to 4% of magnesium sulfate, 1% to 3% of copper sulfate, 2% to 4% of zinc sulfate, 0.1% to 0.3% of ammonium molybdate, and 2% to 4% of ferrous sulfate. The rare earth plant growth regulator provided by the invention is rapid in plant leaf fertilization response, provides nutrient elements for plant growth, can promote development of plant roots, fixes nitrogen, dissolves phosphorus and dissolves potassium, improves a fertilizer utilization rate by 20% to 30%, can enable plants to sufficiently absorb nutriments to reach balance complementation, improves soil, fosters fertile soil strength, resists to continuous cropping, enables fruit and vegetable crops to be early-maturing, increases yield by 15% to 30%, resists to storage, can further prevent and treat rotten diseases such as plant mould and the like, degrades a residual pesticide, is efficient, green and pollution-free, improves quality of agricultural products and prolongs refreshing time.

Description

technical field [0001] The invention belongs to the field of rare earth application technology, and in particular relates to a rare earth plant growth regulator. Background technique [0002] Rare earths are lanthanide elements in the periodic table of chemical elements, referred to as rare earths, and their symbols are represented by Re or R. Rare earth elements include 15 elements in the lanthanide series (atomic numbers from 57 to 71) and 17 elements such as scandium and yttrium. According to some differences in their properties, they are divided into light rare earth elements (scandium, lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium) and heavy rare earth elements (gadolinium, terbium, dysprosium, holmium, erbium, yttrium, thulium, ytterbium, lutetium). Among them, cerium accounts for 48%, lanthanum accounts for 25%, neodymium accounts for 16%, samarium accounts for 2%, lutetium accounts for 5%, and other 12 kinds of elements only account for...
