Abstract
The present invention is a kind of drop cadmium fertilizer and its application method; it is related to a kind of unmanned fog machine Micro trauma foliage-spray method; the following steps are included: Step 1: using unmanned fog machine; dissolution drop cadmium fertilizer; and sprinkling droplet size is adjusted at 50-100 microns; crops are sprayed, observe corps leaf surface afterwards two days later；There is spot of the diameter less than 2mm to corps leaf surface and does not occur the spot that diameter is greater than 4mm, then the fertilising concentration to drop cadmium fertilizer in the concentration for adjusting drop cadmium fertilizer；Step 2: carrying out Large Area of Crops fertilizer test according to the fertilising concentration of drop cadmium fertilizer, the fertilising concentration of fine tuning drop cadmium fertilizer obtains standard spray fertilizer amount.The concentration of cadmium fertilizer drops by increasing in the present invention, increases corps leaf surface to the absorption efficiency of drop cadmium fertilizer, can effectively control the damage caused by blade face.
Description
Technical field
The invention belongs to technical field of agricultural breeding more particularly to a kind of drop cadmium fertilizer and its application methods.
Background technique
A kind of plant protection technology equipment of the unmanned fog machine as spray spraying pesticide lacks research for the application of fertilising aspect.
It is in terms of especially unmanned fog machine is for increasing selenium and drop cadmium and critically important.For example we can spray the beneficial member of some divalent
Element competitively captures the transport protein of cadmium carrying, so that it may prevent cadmium from transporting to the grain of rice, if reaching this with the method for fertilising
As soon as target, then cost is very high, and uses the method for foliage-spray at low cost, unmanned plane is especially used, efficiency is greatly improved,
Cost is lower, but leans on Foliage Absorption due to spraying, and the amount of absorption is too small not to work yet.
Summary of the invention
In order to solve the above technical problems, the invention discloses a kind of unmanned fog machine Micro trauma foliage-spray methods.This hair
The bright concentration by increasing drop cadmium fertilizer, increases corps leaf surface to the absorption efficiency of drop cadmium fertilizer, can effectively control pair
It is damaged caused by blade face.
For this purpose, the technical solution that the present invention takes:
A kind of drop cadmium fertilizer, including manganese sulfate, zinc sulfate, calcium dihydrogen phosphate, magnesium sulfate, ferrous sulfate, chromium sulfate, sub- selenium
Sour sodium, amino acid, urea and sodium metasilicate；Manganese sulfate, zinc sulfate, calcium dihydrogen phosphate, magnesium sulfate, ferrous sulfate, chromium sulfate divalent
Chromium, sodium selenite, amino acid, urea and organosilicon, mass ratio 300:200:600:200:400:50:10:50:500:
100；Sodium metasilicate tune PH to 4-6.
It is further to improve, include the following steps:
Step 1: using unmanned fog machine, dissolution drop cadmium fertilizer, and sprinkling droplet size is adjusted at 50-100 microns,
Crops are sprayed, observe corps leaf surface afterwards two days later；, there is diameter to corps leaf surface and is less than in the concentration for adjusting drop cadmium fertilizer
The spot of 2mm and do not occur diameter be greater than 4mm spot, then be drop cadmium fertilizer fertilising concentration；Wherein, drop cadmium fertilizer with with
With, can not be long placed in overnight；
Step 2: Large Area of Crops fertilizer test is carried out according to the fertilising concentration of drop cadmium fertilizer, fine tuning drop cadmium fertilizer
Fertilising concentration, obtains standard spray fertilizer amount.
Further to improve, when the standard spray fertilizer amount, that is, Large Area of Crops fertilizer test, corps leaf surface has 80%
There is the spot that diameter is less than 2mm in above plant, and does not occur the drop cadmium fertilizer dose of spot of the diameter greater than 4mm.
Further improve, it is dense for the second time in turn to standard spray fertilizer amount according to the chemical examination effect for increasing selenium or dropping cadmium of crops
Degree fine tuning is final fertilising result when reaching best increasing selenium or drop cadmium effect.
Further to improve, the crops are rice.
Further to improve, the sprinkling droplet size is adjusted at 80 microns.
Further to improve, the fertilising concentration of the drop cadmium fertilizer is to different growing, different nutrient supply states and plant
The case where object growth and development instantly, determines respectively.
Specific embodiment
For a better understanding of the present invention, the content that present invention is further explained below, but the contents of the present invention are not only
It is confined to following case study on implementation.
Embodiment 1:
1, one 10 kilograms of drugloading rate of unmanned fog machine, the fertilizer application amount of the drop cadmium fertilizer of 100 mu of dissolution, is sprayed on 20 mu
Area on, by droplet size adjust in 80 microns of progresss small area tests (such as one mu), two days later afterwards observing effect, until blade face
Do not occur sheet concentration to burn and there are the visible a small amount of spots of naked eyes to be advisable, if loseing naked eyes visible speckles, concentration can be improved,
Or spraying droplet size is tuned up, then tested, if sheet burn patch occurs in blade, turns fertilizer application amount down, try three times
Test calibration microoperation spraying concentration.
2, after the fertilizer application amount determined after playing test, the fine tuning of similar test is also carried out once in enlarged-area test,
After repeatedly finely tuning, standard spray fertilizer amount is determined.
3, after by test in 1 year, according to increasing selenium or dropping the chemical examination effect of cadmium, the coming year carries out the second wheel concentration when implementing again
Fine tuning.
4, to increase selenium as target, i.e., drop cadmium fertilizer is to increase selenium fertilizer, and increasing selenium fertilizer includes sodium selenite, potassium dihydrogen phosphate, amino
Acid, urea and potassium metasilicate or sodium metasilicate or sodium metasilicate or sodium metasilicate；Sodium selenite, potassium dihydrogen phosphate, amino acid, urea
It is 10:100:50:200:20 with the mass ratio of potassium metasilicate or sodium metasilicate or sodium metasilicate or sodium metasilicate, it is micro- to offset selenium fertilizer
It is negatively affected caused by wound blade.Preferably match seed strong fertilizer,
5, to drop cadmium as target, i.e. drop cadmium fertilizer is drop cadmium fertilizer, drop cadmium fertilizer include manganese sulfate, zinc sulfate, calcium dihydrogen phosphate,
Magnesium sulfate, ferrous sulfate, chromium sulfate, sodium selenite, amino acid, urea and sodium metasilicate；Manganese sulfate, zinc sulfate, calcium dihydrogen phosphate,
Magnesium sulfate, ferrous sulfate, chromium sulfate divalent chromium, sodium selenite, amino acid, urea and organosilicon, mass ratio 300:200:
600:200:400:50:10:50:500:100；Sodium metasilicate tune PH to 4-6；It is used while allocating, can not be long placed in overnight.
6, the selenium fertilizer Micro trauma Spraying Se-fertilizer for testing five times of concentration of normal spray concentration, makes paddy once spray selenium fertilizer and reaches
It 4000 micro- gs/kg of rice selenium, sprays reached 17000 micro- gs/kg of rice selenium three times.Super Rice enriched-Se can be produced, is reduced big
Rice cadmium content, volume increase 5-15% or so.
The above description is only an embodiment of the present invention, is not intended to limit the scope of the invention, all to utilize this hair
Equivalent structure or equivalent flow shift made by bright description is applied directly or indirectly in other relevant technology necks
Domain is included within the scope of the present invention.
