AI Technical Summary

Problems solved by technology

Compared with common crops, the waxy layer of fruit tree leaves is thicker, which is not conducive to the absorption and utilization of nutrients
General trace element foliar fertilizers have disadvantages such as unreasonable nutrient ratio, poor pertinence, and the fertilizer is not easy to attach to the leaf surface, resulting in low nutrient absorption efficiency, etc.

Abstract

The present invention discloses a kind of microelement type complex foliage fertilizer and its preparation method. The described foliage fertilizer is formed from fulvic acid, sodium salicylate, alginic acid composite solution, special-purpose composite adjuvant and composite microelement solution (solution A and solution B), in which said solution A is made up by dissolving 100-150kg of citric acid in 250L of water with 60-80deg.C, then successively adding 100-150kg of FeSO4.7H2O, 50-100kg of CuSO4.5H2O, 20-50kg of MnCl2.6H2O and 250-300kg of Zn(NO3)2.7H2O, and the solution B is made up by dissolving 50-100kg of boric acid in 100 L of water with 40-60deg.C, then adding 20-50kg of potassium hydroxide, making them be fully reacted and regulating pH value to 5-6. Its preparation method includes the following steps: adding the solution B into the solution A, stirring them, adding 100-150kg of urea, adding 30-80L of fulvic acid, sodium salicylate and alginic acid composite solution, adding 1kg of sodium hydrogen sulfite and 20-50L of special-purpose adjuvant, regulating pH value to 3-3.5, then adding water to 1000L.

Description

1. Technical field [0001] The invention relates to a trace element type compound foliage fertilizer and its preparation and application method, and more particularly relates to a trace element type compound foliage fertilizer which can enhance fruit coloring ability and increase fruit sugar content. 2. Background technology [0002] The fertilization method of spraying diluted and dissolved fertilizer directly on the leaves of plants is called foliar fertilization. Foliar fertilization is one of the commonly used methods of fertilization by farmers. Foliar fertilization has the characteristics of fast nutrient absorption, high fertilizer utilization rate, and convenient operation. With the development of agricultural production, foliar fertilization has become an important measure to increase production. [0003] The nutrient supply of fruit trees is closely related to the quality of the fruit, and correct fertilization is one of the most important factors affecting the qu...
