Problems solved by technology

Inorganic fertilizers do not have the effect of biostimulants and the effect of rooting and rooting. Ordinary organic fertilizers are not water-soluble and quick-acting, especially in winter. Due to the low temperature, the absorption and utilization rate of a single fertilizer is low.
Crops grow slowly under harsh environmental conditions such as high temperature, drought, and low temperature, and the biostimulant effect of a single inorganic fertilizer or a single organic fertilizer is poor

Abstract

The invention relates to a coated fertilizer as well as a production method and application thereof. The coated fertilizer is prepared from the following raw materials in parts by weight: 10 to 15 parts of potassium fulvate, 5 to 10 parts of fulvic acid, 30 to 35 parts of potassium nitrate, 20 to 25 parts of potassium dihydrogen phosphate, 3 to 5 parts of EDTA ferric sodium salt, 1 to 3 parts of manganese disodium EDTA trihydrate, 1 to 3 parts of copper disodium EDTA, 3 to 5 parts of zinc disodium EDTA and 1 to 3 parts of ammonium molybdate. The coated fertilizer according to the invention canprovide nutrition for crops, also can activate various synthetases in crops and improve cell membrane permeability, thereby improving nutrient absorption and fertilizer utilization rate. The coated fertilizer has a very good biological stimulation effect under harsh conditions such as high temperature, low temperature and drought.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a coated fertilizer and a preparation method and application thereof. Background technique [0002] At present, most of the fertilizers on the market are inorganic fertilizers that supplement inorganic nutrients alone or organic fertilizers that simply supplement organic nutrients. Inorganic fertilizers do not have the effect of biostimulants and rooting and rooting. Ordinary organic fertilizers are not water-soluble and quick-acting, especially in winter, due to the low temperature, the absorption and utilization rate of a single fertilizer is low. Crops grow slowly under harsh environmental conditions such as high temperature, drought, and low temperature, and single inorganic fertilizer or single organic fertilizer has poor biostimulation effect. SUMMARY OF THE INVENTION [0003] An object of the present invention is to provide a coated fertilizer. [0004] A coated fertilizer a...
