Abstract
A kind of iron fertilizer correcting fruit tree and forest Iron Deficiency Chlorosis, its preparation method is for be first dissolved in 100mL deionized water by monosodium glutamate 5-8g, with the hydrochloric acid of volumetric ratio 1:1, the pH value of solution is adjusted to 4.3, then adds ferrous sulfate 1.7g-2.5g, then add 1400mL deionized water.The iron fertilizer of rectification fruit tree of the present invention and forest Iron Deficiency Chlorosis, directly input in fruit tree or forest body, ferrous iron is not easily converted into ferric iron, and fruit tree and forest easily absorb, and multiple green successful, formula is simple, with low cost, easily configures, easy to operate.
Description
Technical field
The invention belongs to the iron fertilizer field of correcting fruit tree and forest Iron Deficiency Chlorosis.
Background technology
Fruit tree and forest Iron Deficiency Chlorosis are global century property difficult problems, since French scientist Gris1843 finds grape leave Iron Deficiency Chlorosis, though through more than 150 years storm strongholds in defiance of difficulties, still do not solve fruit tree and forest Iron Deficiency Chlorosis problem completely so far.Why fruit tree and forest Iron Deficiency Chlorosis are difficult to correct, and major cause is the ferrous iron that can only absorb due to the root system of fruit tree and forest in soil, can not absorb ferric iron, and the iron in soil exists mainly with ferric iron.No matter divalence iron fertilizer is be manured into soil or foliage-spray, is all very easily oxidized into ferric iron, causes rectification Iron Deficiency Chlorosis effect bad.Directly being inputted by iron fertilizer in fruit tree and forest body, prevent divalence iron fertilizer oxidized in atmosphere, is a kind of better method that iron fertilizer is used.
Mainly contain following several at present the iron fertilizer of fruit tree and forest transfusion:
1. ferrous sulfate, be the most frequently used inorganic divalence iron fertilizer, its advantage is easy to use, low price, and shortcoming is dissolved in water rear section to be oxidized to ferric iron, corrects Iron Deficiency Chlorosis less effective after transfusion.
2. ironic citrate, because its aqueous solution is in acid, the impact by light and heat is reduced to ferrous salt gradually.After transfusion, effect is more stable than ferrous sulfate, but easily fertilizer damage occurs.
3.EDTA-Fe, this is a kind of ferrous inner complex, and proterties is stablized, and be not easy to be oxidized into ferric iron, fertilizer efficiency is high, but transfusion effect is unstable, and it is bad that lower concentration corrects Iron Deficiency Chlorosis effect, and high density very easily produces fertilizer damage.
For above Problems existing, explore new iron fertilizer formula very necessary.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of iron fertilizer formula can being corrected fruit tree and forest Iron Deficiency Chlorosis by transfusion preferably.
The present invention solves the problems of the technologies described above with following technical scheme:
The preparation method of this iron fertilizer is: be first dissolved in 100mL deionized water by monosodium glutamate (Sodium Glutamate) 5-8g, with the hydrochloric acid of volumetric ratio 1:1, the pH value of solution is adjusted to 4.3, then adds ferrous sulfate 1.7g-2.5g, then add 1400mL deionized water.
By from trunk or the method from root input iron fertilizer, correct fruit tree or forest Iron Deficiency Chlorosis.
The iron fertilizer of rectification fruit tree of the present invention and forest Iron Deficiency Chlorosis is a kind of a kind of iron fertilizer utilizing monosodium glutamate and ferrous sulfate to be formed under sour environment.Can directly infuse to the fruit tree of Iron Deficiency Chlorosis and forest, and ferrous iron is not easily converted into ferric iron, fruit tree and forest easily absorb, and multiple green successful, formula is simple, with low cost, easily configures, easy to operate.
Embodiment
When fruit tree and forest start to occur Iron Deficiency Chlorosis, by above-mentioned recipe configuration iron fertilizer, then fruit tree and forest are infused.Infusion model has from root input or inputs two kinds of modes from trunk.Being dig the thick root of 3-5 bar diameter 0.5-1.0cm by suffering from the tree of Iron Deficiency Chlorosis from root input, root being inserted and fills in the rubber finger sleeve of this iron fertilizer solution or in bottle, by this iron fertilizer from root system input tree body.Make a call to a hole identical with hose diameter with electric drill on tree body trunk from trunk input, one end of flexible pipe is inserted in the containers such as bottle that iron fertilizer solution is housed or bag, the other end of flexible pipe, with washing after solution drinks up by ball, inserts in the hole of tree body trunk, is inputted by iron fertilizer in fruit tree and forest body.
Embodiment 1:
On May 8th, 2009, at China Agricultural University's Quzhou experiment centre, is examination material by red fuji apple kind, carries out this iron fertilizer input from trunk Iron Deficiency Chlorosis tree.Solution ph, for be first dissolved in 100mL deionized water by 7.167g monosodium glutamate, to be then adjusted to 4.3 with volumetric ratio 1:1 hydrochloric acid, then to add 2.5g ferrous sulfate by iron fertilizer formula, after stirring ferrous sulfate dissolving, then adds 1400mL deionized water.Ferrous sulfate concentration is 5.99 × 10
-3mol/L.After 10 days, chlorosis tree is multiple green by chlorosis grade 2 before treatment is the chlorosis grade 0.49 after process, chlorophyll content in leaf blades is by 0.41mg/g(fresh weight before treatment) increase weight the 1.6mg/g(fresh weight after extremely processing), this iron fertilizer process of chlorosis vanes, obtains significantly multiple green.
Embodiment 2:
Test is carried out in Cao Zhuan village of Yongnian County of Hebei province, and experimental cultivar is the starring apple of Pressure trunk injection, and every strain on May 3 tree digs the root of 5 diameter about 1cm, and insertion fills 100mL respectively, concentration is 5.99 × 10
-3in this formula iron fertilizer solution of mol/L, process investigation in latter 10 days, chlorosis rank, by before treatment 2.50, returns to 0.49 after process, chlorophyll content is by 0.71mg/g(fresh weight before treatment) increase to the 0.93mg/g(fresh weight after process), multiple green Be very effective.
Above result shows: for fruit tree or the forest of Iron Deficiency Chlorosis, with the formula of monosodium glutamate and ferrous sulfate, by the method for siphon infusion or root insertied, can within a short period of time significantly multiple green.
Claims (1)
1. correct the iron fertilizer of fruit tree and forest Iron Deficiency Chlorosis for one kind, comprise ferrous sulfate, it is characterized in that preparation method is: be dissolved in by monosodium glutamate 5-8g in 100mL deionized water, with the hydrochloric acid of volumetric ratio 1:1, the pH value of solution is adjusted to 4.3, then add ferrous sulfate 1.7g-2.5g, then add 1400mL deionized water.
