Description

A kind of water-soluble clover dedicated liquid composite foliage fertilizer and its application
The invention belongs to fertilizer fields in agricultural for technical field, and in particular to a kind of water-soluble clover dedicated liquid is compound Foliar fertilizer and its application.
Background technique foliar fertilizer has the characteristics that fertilizer efficiency is high, easily absorbs, and has good effect to the increasing yield and improving quality of crops, It is had been widely used on crops, fruit tree, vegetables, herbage.Alfalfa (Medicago satival) is that pulse family clover belongs to more Year raw herbaceous plant, protein, minerals, multivitamin and carrotene rich in alfalfa cauline leaf, especially Be that content is higher in blade, be the main plant-protein additive of feed, there is the title of " King of Pasture ", be milk cow, beef cattle, The high-quality careless feed of sheep, pig.Especially clover is high quality forage for cattle-raising, can both improve butterfat percnetage, can also be made Vitamin content increases in cow's milk, especially liposoluble vitamin.Therefore, the yield and quality of Alfalfa is also increasingly subject to close Note.Growth of Alfalfa year limit for length, cradle in year using often, the nutrient absorbed from soil is also more, therefore is matched by science System, the rational application of fertilizer increase nutrient, have significant role to the yield and quality for improving clover.Composite foliage fertilizer both can provide battalion Support, but can Effective Regulation crop growth and development, be the developing direction of foliar fertilizer.Document (Wang Junping, Zhai Zhixi, He Zhongpei, Deng, regulating and controlling effect of the DTA-6 to alfalfa crude protein and amino acid content, China Agricultural University's journal, 2003,8 (3): 25- 28) report DTA-6 (diethylamino ethanol caproate) plant growth regulator has a production-increasing function to clover Herbage harvest, and appropriate dose Amount can increase protein content in alfalfa stem and leaf.Less, patent CN is reported in the research for being exclusively used in the composite foliage fertilizer of clover at present 102731204 B disclose a kind of foliar fertilizer preparation method for promoting acid soil Alfalfa, which uses In terms of promoting the growth of acid soil alfalfa seedling, but not being improved the qualities such as property of alfalfa protein, amino acid content Report.The present invention is a kind of water-soluble clover dedicated liquid composite foliage fertilizer, in acid, basic soil alfalfa have Increasing yield and improving quality effect, it is not disclosed at home and abroad.
Summary of the invention the object of the present invention is to provide it is a kind of promotion alfalfa yield, improve protein content it is water-soluble Type dedicated liquid composite foliage fertilizer and preparation method thereof.Preparation process is simple, at low cost, and effect is good.
Technical scheme is as follows:
Water-soluble clover dedicated liquid composite foliage fertilizer of the present invention, it is composed of the following components, it is shown in Table 1.

Naphthaleneacetamide citrate
The preparation method of the foliar fertilizer are as follows:
(1) aequum citric acid and EDETATE DISODIUM are weighed by formula rate, water is added to be heated to 40-60 DEG C of dissolution.By matching Square ratio weighs aequum zinc gluconate, manganese sulfate, ferrous sulfate heptahydrate, ammonium molybdate, boric acid or borax, finely ground, is added to In citric acid and EDETATE SODIUM saline solution, stirring and dissolving can suitably be heated to 40-80 DEG C to improve meltage, obtained solution A。
(2) aequum potassium dihydrogen phosphate and urea are weighed by formula rate, be dissolved in water, obtained solution B.
(3) aequum humic acid being weighed by formula rate, the KOH that 5-10% is added is neutralized to pH value 6-8, stirring and dissolving, It is filtered to remove insoluble matter, obtained solution C.
(4) required surfactant is weighed by formula rate, be dissolved in water, obtained solution D.
(5) a certain amount of plant growth regulator (sorb amide betaine, cinnamamide glycine betaine or naphthaleneacetamide are weighed Citrate any or two kinds, three kinds of mixture) be dissolved in water obtained 100ppm mother liquor, it is diluted according to formula rate amount To required concentration, obtained solution E.
(6) above-mentioned solution A, B, C, D, E are added in reaction kettle by formula rate, are heated to 40-60 DEG C and are stirred Uniformly, certain volume is added water to, if there is insoluble matter is then filtered to remove, composite foliage fertilizer stoste is made.It packs and product is made.
The advantages and positive effects of the present invention:
Water-soluble liquid composite foliage fertilizer of the present invention a great number of elements N, P, K according to needed for alfalfa growing, trace elements zn, Fe, Mn, Mo, B, S, organic nutrition humic acid, citric acid, growth regulating promotor sorb amide betaine, cinnamamide beet Alkali or naphthaleneacetamide, fungicide bamboo vinegar etc. is at being grouped as.Zn, Fe, Mn, Mo are more sharp by forming chelate with EDTA, citric acid In plant absorption.Fertilizer of the present invention is applied to alfalfa, can promote the sturdy prosperity of clover rhizome, improves clover tiller energy Power, drought resisting and lodging resistance improve alfalfa stem and leaf protein content, with unexpected volume increase and improve alfalfa product The effect of matter.It is especially raw using sorb amide betaine, cinnamamide glycine betaine or naphthaleneacetamide class new type water-solubility plant Long regulator plays key facilitation to the degeneration-resistant of clover, volume increase and upgrading.Bamboo vinegar has killing to harmful bacteria in soil Effect can also promote beneficial microorganism in soil to multiply.Foliar fertilizer stoste clear water is diluted 500 times, in lucerne Mu growth period sprays 2 times, and every time dosage is 100-150mL foliar fertilizer stoste/mu, and 40-54% can be improved in alfalfa output, especially Gross protein value in alfalfa stem and leaf (being increased to 22-23% by 18.6%) greatly improved, significantly improve the quality of clover. Clover purchases standard of entering refirigeration regulation: gross protein value >=20% is superfine, and gross protein value >=18% is level-one, crude protein Matter content >=14% is second level.Gross protein value is per ton high by 400 in 20% or more unit price more below than 20% currently on the market More than first (RMB).The economic benefit for applying product of the present invention is very significant, and three batches of harvesting can increase income 800-1000 member per acre (RMB).Water-soluble clover dedicated liquid composite foliage fertilizer of the present invention also has at low cost, pollution-free, safe and convenient to use Advantage has very high application value and commercialization potentiality.
It should be clear that various transformation and change can be carried out in scope defined by the claims of the present invention.
