Multifunctional element-balance activating leaf fertilizer and preparation method and application thereof

Abstract

The invention discloses a multifunctional element-balance activating leaf fertilizer and a preparation method and application thereof. Each bag of multifunctional element-balance activating leaf fertilizer contains 325.7 g of urea, 150 g of monopotassium phosphate, 120 g of amino acid chelated iron, 213.7 g of amino acid chelated magnesium, 10.8 g of amino acid chelated copper, 62.8 g of amino acid chelated zinc, 109 g of amino acid chelated manganese, 11.7 g of disodium octaborate tetrahydrate, 75.8 g of amino acid chelated molybdenum, 20 g of aspirin and 0.5 g of sodium selenite. The preparation method is that all the raw materials are mixed evenly and then are split-charged, and each bag is 1100 g. According to the application, the leaf fertilizer is directly sprayed on the leaf surfaces of plants after being diluted with water to 30-45 times, and each bag of leaf fertilizer is used for application in 1 mu of land. The leaf fertilizer is simple to apply, the content of fertilizer nutrients, element balance and the water solubility, stability and activation ingredients of the fertilizer are remarkably improved, thus an application effect is good, and the multifunctional element-balance activating leaf fertilizer has a very good yield-increasing effect and an application prospect.

Description

technical field [0001] The invention relates to the field of foliage fertilizer, in particular to a multifunctional element balance activation foliage fertilizer, and also relates to a preparation method and application of the foliage fertilizer. Background technique [0002] Foliar fertilizer is a type of fertilizer that applies nutrients to the surface of crop leaves and exerts its function through the absorption of leaves. The leaves of plants have upper and lower layers of epidermis, which are composed of epidermal cells. There are cuticles and waxes on the outside of the cells on the surface. It can protect the mesophyll cells under the epidermis to perform photosynthesis, respiration and other functions, and not be affected by changes in external adverse conditions. There are many tiny pores on the surface of the leaves, which perform the function of gas replacement. The use of foliar fertilization can make nutrients quickly Enter the plant body through the leaves to s...

Problems solved by technology

However, the normal growth and development of plants not only requires the cooperation of multiple elements, but also depends on whether the elements are balanced. If the balance of elements is not good, the plant physiological mechanism will not be able to operate in the best state, so it will be difficult to play its best role. high quality and high yield

[0005] 2. The water solubility of the fertilizer is poor: the background foliar fertilizer is a solid powder, so it is required to have good water solubility. However, the water solubility of boric acid and ammonium molybdate is poor. It is found in practical applications that even for a long time Stirring is also difficult to completely dissolve, especially EDTA, which has very poor water solubility, so it is not only inconvenient to use, but also difficult to play the proper role of some ingredients

[0006] 3. The stability of some components is poor: the nature of ferrous sulfate is very unstable, and it is easy to oxidize and deteriorate. In addition, the stability of some other components is also poor. Among these components, some are cations and some are anions. In effect, some anions and cations will inevitably react with each other and lose their respective effects. The above-mentioned patent adopts the measure of adding EDTA to shield the cations, but it is found through tests that the water solubility of EDTA is very poor, so the effect is not good. Changing to EDTA-2Na salt with good water solubility, the actual effect is not good

[0007] 4. Insufficient activating ingredients: the activating ingredient in the background foliage fertilizer is only fulvic acid, and the spraying concentration is only 0.26%-0.347%, which is far from the best spraying concentration of fulvic acid which is 5%-10%. Far
