Description
Technical field
The invention belongs to agriculture field, and in particular to a kind of sodium alginate base blade face of promotion potato plant root block growth
Fertilizer and preparation method thereof.
Background technology
The main path of plant absorption nutrient has two, i.e. root and leaf.Crop mainly absorbs soil or battalion by root
Nutrition supply growth and development of plants in nutrient solution, in addition to root system, crop can also be absorbed by cauline leaf (especially blade) to be supported
Point, the phenomenon of this non-Root Absorption nutrition is exactly the exoroot nutrition of crop during plant growth, in addition to crop root
Nutrient absorption surface fertilising measure be typically exactly foliage dressing.The construction of leaf is different from root, blade have three kinds of approach with
The external world carries out mass exchange, and one is the stomata by being distributed mainly on blade face；Two be the hydrophilic aperture of leaf surface cuticula；Three are
It is the same to root system surface by the matter ectodesma of blade cell, by active absorption absorption of nutrient ingredients to blade interior.Cause
This, blade also has the characteristics of selection absorbs as root system to nutriment leaf, is also one kind that crop absorbs nutriment
Approach.
With the reach of science, the breakthrough of theory, social advance is developed into the modern times from single subject to cross discipline
The inexorable trend of scientific development.The need for foliar fertilizer commonly used at present can not meet plant growth, it is badly in need of exploitation one
Strong sprout, degeneration-resistant, anti-evil, the fertilizer of increasing both production and income effect can be played by planting.
The content of the invention

0.15：0.2-0.3；
（3）Methyl α-naphthyl acetate, thionyl chloride are added in reaction vessel, DMF is slowly added dropwise under stirring, is heated
To flowing back, return stirring 7-8h rotates out excessive thionyl chloride, obtains naphthalene chloroacetic chloride；Under the conditions of ice-water bath, by N, N- bis-
Ethylethylenediamine is added to pyridine and tetrahydrofuran with mass ratio 1：The in the mixed solvent that 2-3 is prepared, is mixed evenly, and raises
Naphthalene chloroacetic chloride and tetrahydrofuran is slowly added dropwise with mass ratio 1 to 70-75 DEG C in temperature：The mixed solution that 4-6 is prepared, completion of dropping
Afterwards, temperature constant magnetic stirring 20-24h is continued, rotation steams solvent, and gains are poured into 80-100 times of aqueous hydrochloric acid solution, stands
20-24h, is filtered, and washing, filter cake uses recrystallisation from isopropanol of 4-5 times equivalent to filter cake parts by weight, is dried, is obtained methyl α-naphthyl acetate
Derivative；Wherein the mass ratio of methyl α-naphthyl acetate, thionyl chloride and DMF is 1：1.3-1.4：0.08-0.1；N, N-
Diethyl ethylenediamine：Mixed solvent：The mass ratio of naphthalene chloroacetic chloride is 0.5-0.6：8-10：1；
（4）Sodium alginate will be modified to be added in the deionized water equivalent to 100-120 times of sodium alginate parts by weight of modification, 50-
60 DEG C of mixing 50-60min, are cooled to room temperature, add naphthylacetic acid derivant, urea, copper sulphate and potassium dihydrogen phosphate, ultrasound
Scattered 30-40min, adds boric acid, ammonium molybdate, olefin conversion and octyl phenol APEO, continues mixing at room temperature and stirs
2-3h is mixed, the sodium alginate base foliar fertilizer of potato plant root block growth is promoted, wherein modification sodium alginate, methyl α-naphthyl acetate spread out
Biology, urea, copper sulphate, potassium dihydrogen phosphate, boric acid, ammonium molybdate, the mass ratio of olefin conversion and octyl phenol APEO
For 1：0.008-0.01：5-6：0.08-0.1：0.2-0.3：0.06-0.08：0.08-0.1：0.1-0.12：0.12-0.15.
The preparation method of the described sodium alginate base foliar fertilizer for promoting the growth of potato plant root block, it is characterised in that
Step（1）Middle hydroxylamine hydrochloride-aqueous isopropanol is 8-10% hydroxylamine hydrochloride-aqueous isopropanol, sodium hydroxide-aqueous isopropanol
For 8-10% sodium hydroxide-aqueous isopropanol.
The preparation method of the described sodium alginate base foliar fertilizer for promoting the growth of potato plant root block, it is characterised in that
Step（3）The concentration of middle aqueous hydrochloric acid solution is 0.01-0.02mol/L.
The preparation method of the described sodium alginate base foliar fertilizer for promoting the growth of potato plant root block, it is characterised in that
Step（4）In ultrasonic disperse temperature be 50-60 DEG C, supersonic frequency is 450-500Hz.
The beneficial effects of the invention are as follows：
The present invention reacts hydroxyl active in sodium alginate and ethyl chloroacetate, and-OH is converted into-OCH2COOH, modification sea
Mosanom, the ability that carboxyl is dissolved in water is more than hydroxyl so that sodium alginate has higher water solubility, while active hydroxyl groups subtract
Less improve its chemistry of aqueous solution stability, the viscosity reduction of the aqueous solution causes other monomers and element more uniformly to enter
Between its strand, sequestering power is improved；And sodium alginate can stimulate plant growth in itself, photosynthesis and enzyme are improved
Vigor, promotes the formation of chlorophyll, possesses good sequestering power, promotes absorption of the plant to nutrient, improve crop it is disease-resistant,
Resistance, improving quality increases yield.The present invention is by methyl α-naphthyl acetate chloride, and with N, the reaction of N- diethyl ethylenediamines obtains naphthalene second
Acid derivative；Methyl α-naphthyl acetate and its this kind of auxin of derivative have the characteristic easily conducted downwards in bast, naphthalene second
The addition of acid derivative, the nutrient needed for promotion plant is conducted to root via stalk by Foliage Absorption, can be promoted branches and leaves
And root growth, increase chlorophyll content, strengthen photosynthetic capacity, branch strengthens full of leaves, promotion bud differentiation, increases number of flowers, improve
Utilization rate of fertilizer, so that increasing both production and income.The present invention using sodium alginate as chelating agent, chelating chelating plant needed for a great number of elements and
Trace element, with slow release action, extends action time, and can significantly reduce its resolution ratio in storage.This
Invention adds octyl phenol APEO and olefin conversion, not only causes the foliar fertilizer of the present invention to have preferable wettability
And increase plant antibiotic property, be more easy to be absorbed by crops in application, thus promote plant growth, bloom, result, enter one
What is walked causes crop yield.Nutriment and naphthylacetic acid derivant necessary to the foliar fertilizer of the present invention has plant growth,
Plant leaf surface is sprayed onto, is absorbed by blade face by plant, so as to improve fertilizer efficiency utilization rate and the supplement to trace element, is promoted
Potato plant root block grows, so that increasing both production and income.
