Abstract
The invention discloses a kind of foliage fertilizer preventing and treating pear tree iron deficiency disease disease, described foliage fertilizer is in citrate-phosphate disodium hydrogen damping fluid, the component containing following massfraction: 0.8 ~ 1% ferrous sulfate, 0.2 ~ 0.3% magnesium sulfate, 0.1 ~ 0.2% zinc sulfate, 0.1 ~ 0.2% manganous sulfate.The present invention has the following advantages: 1) use conveniently, be sprayed directly on to blade, easy handling, is easy to promote; 2) blade can be made to return green, instant effect, successful, greatly alleviate the yellow symptom of pear tree; 3) improve growth conditions, tree body is easy to absorb, and has the effect promoting nutritive equilibrium and strengthen tree vigo(u)r.
Description
Technical field
The invention belongs to compound manure field, particularly a kind of foliage fertilizer preventing and treating pear tree iron deficiency disease disease.
Background technology
Up to the present Iron-deficiency Chlorosis of Fruit Trees disease rescues technology has a variety of, major part concentrates on soil application method, inorganic iron fertilizer, various Complexing Irons that stability is stronger, chelated iron and applying organic manure etc. is imposed in soil, although yellow symptom can be alleviated to a certain extent, but affect greatly by P in soil H, take effect slow, and it is easily oxidized to use inorganic iron fertilizer in rhizosphere soil, foliage top dressing is held time not long; Use chelating iron fertilizer cost high, need continuous administration, prior art can not solve root problem.
Summary of the invention
Goal of the invention: the object of this invention is to provide a kind of foliage fertilizer preventing and treating pear tree iron deficiency disease disease.
Technical scheme: the invention provides a kind of foliage fertilizer preventing and treating pear tree iron deficiency disease disease, described foliage fertilizer is in citrate-phosphate disodium hydrogen damping fluid, the component containing following massfraction: 0.8 ~ 1% ferrous sulfate, 0.2 ~ 0.3% magnesium sulfate, 0.1 ~ 0.2% zinc sulfate, 0.1 ~ 0.2% manganous sulfate.
Described citrate-phosphate disodium hydrogen damping fluid is 0.2mol/LNa
2hPO
4formulated with 0.1mol/L citric acid.
Citrate-phosphate disodium hydrogen buffer solution ph is 3.4 ~ 5.0.
In described citrate-phosphate disodium hydrogen damping fluid, the component containing following massfraction: ferrous sulfate is 1%, magnesium sulfate is 0.2%, zinc sulfate is 0.1%, manganous sulfate is 0.2%.
The PH of described foliage fertilizer is 3.5 ~ 3.9.
Beneficial effect: compared with prior art, the present invention has the following advantages:
1) use conveniently, be sprayed directly on to blade, easy handling, be easy to promote;
2) blade can be made to return green, instant effect, successful, greatly alleviate the yellow symptom of pear tree;
3) improve growth conditions, tree body is easy to absorb, and has the effect promoting nutritive equilibrium and strengthen tree vigo(u)r.

Experimental example
Three kinds to be filled a prescription a.1% ferrous sulfate+0.2% magnesium sulfate+0.1% zinc sulfate+0.2% manganous sulfate in May, 2012 at Yangzhou University and plant protection institute orchard buffered soln of imparting knowledge to students by researchist; b.1% ferric sulfate; c.0.2% manganous sulfate is modulated into PH respectively and on " new peak " Sand Pear yellow blade, draws " C " character after 3,4,5,6,7,8, observes it and returns green situation.
The blade processing the ferrous solution process finding PH=3 and 4 of being filled a prescription by a can show " C " character clearly, and returned green respond well by the position of smearing, the ferrous solution of PH=5 to 8 can not significantly demonstrate " C ".
The blade of all ferric irons and manganese sulfate solution process all fails to demonstrate significantly " C " character, and returning green effect is not clearly.
