Abstract

The invention discloses an aid-containing trace element foliar fertilizer and a preparation method thereof. Each 100 kilograms of trace element foliar fertilizer comprises the following substances: 6 to 12 kilograms of copper sulfate, 3 to 8 kilograms of ferrous sulfate, 12 to 17 kilograms of zinc sulfate, 7 to 11 kilograms of manganese sulfate, 1.0 to 2.5 kilograms of boric acid, 2.0 to 5.0 kilograms of ethylene diamine tetraacetic acid (EDTA) disodium, 1.0 to 5.0 kilograms of citric acid, 5.0 to 10.0 kilograms of alkyl glucoside and the balance of water. Application results indicate that the trace element foliar fertilizer, after being sprayed onto the surfaces of laminae, can be better spread on the laminae to plat the nutritional effect fully; and due to the addition of an aid, the absorption of the laminae on four elements of Fe, Mn, Cu and Zn is improved, and the growth vigor and biomass of crops are increased obviously.

Description

technical field

[0001] The invention relates to a trace element foliage fertilizer containing additives and a preparation method thereof. Background technique

[0002] With the continuous improvement of the level of modern agriculture and the increase in the amount of chemical fertilizers, the problem of lack of trace elements has become increasingly prominent, and in some places it has become an obstacle to crop production. In the field of agricultural science and technology, the essential nutrient elements with a content of 0.2-200mg / Kg are called trace elements. There are 7 kinds of essential trace elements, such as iron, manganese, copper, zinc, boron, molybdenum, and chlorine. The growth and development of plants need to absorb various Nutrients, but the plant yield is determined by the effective plant growth factor with the smallest relative content in the soil, and the yield also changes accordingly within a certain limit with the increase or decrease of this factor. ...
