Abstract

The invention belongs to the field of agricultural fertilizer processing, and discloses a sun-screening foliar fluid fertilizer and a preparation method thereof. The fluid fertilizer is prepared from the following components in percentage by mass: 10-40 percent of sun-screening agents, 8-20 percent of water-soluble calcium salt, 0.5-2 percent of water-soluble boron salt, 1-12 percent of water-soluble zinc salt, 4-8 percent of water-soluble potassium salt, 1-7 percent of a wetting agent, 1-5 percent of an anti-freezing agent, 4-10 percent of a dispersing agent, 0.1-1.0 percent of a defoaming agent, 0.1-2.0 percent of a thickening agent and the balance of water. The sun-screening foliar fluid fertilizer has sun-screening and resisting effects and an effect for improving disease resistance by selecting titanium dioxide, calcium carbonate, zinc oxide and the like as the sun-screening agents and adding trace elements, namely calcium, boron, zinc and the like, for reinforcing plant adverse resistance. Field test production application proves that the sun-screening foliar fluid fertilizer has a remarkable sun-screening effect, and has a preventing and controlling effect reaching 80-90 percent.

Description

technical field [0001] The invention belongs to the field of agricultural fertilizer processing, and in particular relates to a foliar fluid fertilizer with sun-proof function and a preparation method thereof. Background technique [0002] Every summer, the sun is very strong and the temperature is high, especially in the event of drought. If irrigation is not timely, some vegetables, fruits and even fruit trees will be burned. Among them, citrus sun fruit is more frequent, also known as sunburn fruit. Citrus sunburn is the burning of the peel tissue caused by too strong light, and it usually occurs seriously on the top of the tree with few branches and leaves, which are not easy to be shaded and sunny. It is one of the main diseases of citrus, which seriously affects the appearance and quality of the fruit, resulting in reduced yield and quality. For the prevention of sunburn, lime milk can usually be sprayed on the fruit surface to reduce damage. Now there is no nutriti...
