Description
Technical field
The present invention relates to agricultural production equipment technical field, specifically a kind of Oryza sativa L. site-directed quantitative deep fertilizer spraying
Device.
Background technology
Oryza sativa L. is one of topmost cereal crops of China, and its total output accounts for the 1/2 of whole nation total output of grain,
Its cultivated area accounts for the 1/5 of the world.In paddy ecosystem, nitrogen is again the important restricted of Rice Production
A great number of elements, is also mankind's enormous motivation of improving yield.China's Monitoring of Paddy Rice Plant Area in recent years accounts for the world
20%, and nitrogen fertilizer amount accounts for world's Oryza sativa L. nitrogen fertilizer amount 37%, current China rice field single cropping nitrogen fertilizer amount average out to
180kg/hm2, exceeds 75% than world unit area consumption.After Irrigated paddy field applied nitrogen, due at soil
The volatilization of ammonia in earth-water system, Denitrification, surface loss and seepage effect etc. cause loss of nitrogen fertilizer,
Therefore utilization rate of nitrogen fertilizer is the most on the low side.After nitrogenous fertilizer face is executed, in the water of surface, rice field, ammonium nitrogen concentration increases, pH value
Rise, thus cause the volatilization loss of ammonia.N-dressed deeply is that raising submerged weir flow utilization rate of nitrogen fertilizer is maximally effective
Approach.Compared with traditional top application method, N-dressed deeply can not only reduce the loss of nitrogen, and can increase
Yield.Therefore, N-dressed deeply tends to obtain higher the Agronomic Use Efficiency.Large granule carbamide uses deep placement
Method, its suitable nitrogen fertilizer amount be traditional fertilization method require optimum dose 76%～93%.
China's rice mechanical transplanting area expands rapidly at present, enters near rice shoot by deep application of fertilizer while the machine transplanting of rice,
Make fertilizer slowly discharge and meet paddy growth demand, it is achieved rice mechanical transplanting and the purpose of fertilizer mechanical deep fertilizing.Mesh
Front method and the equipment that equipped mechanical deep fertilizing is fertile on rice transplanter has been researched and developed.Such as patent " 93246725.3 "
Fertilizer spreader for rice transplanter, this device is in actual job, and defertilizing opening is often blocked by mud, makes by changing
The chemical fertilizer of fertile flow by gravity can not apply in the paddy field soil of rice seedling sidepiece, dose it cannot be guaranteed that,
Have impact on Oryza sativa L. yield per unit area to improve.And for example patent " 200820089772.7 " gas-blowing type side subsoil application
Rice transplanter, gas-blowing type side subsoil application paddy rice transplanter is to cover at trench digging to increase a dress of blowing in mud technology
Put, use gas to be blown out from fertilizer delivering pipe by fertilizer, it is to avoid defertilizing opening blocks.Although reaching to eliminate and avoid
The problem of paddy field rice transplanter side deep fertilizing pipe operation blocking, but it is also required to utilize plough to ditch, so can
Cause rice shoot adnexa mud to pile up, so that the degree of depth of rice transplanting deepens, affect machine transplanting of rice quality, simultaneously at mud
Middle trench digging effect is bad, is extremely difficult to real deep fertilizer spraying effect.
Summary of the invention
The problem that it is an object of the invention to exist for above-mentioned technology, it is provided that a kind of Oryza sativa L. site-directed quantitative deep fertilizer spraying
Device.
For achieving the above object, the technical solution used in the present invention is: a kind of Oryza sativa L. site-directed quantitative deep fertilizer spraying dress
Putting, including rice transplanter, support assembly, fertilizer box fixed mount and fertilizer box, it is total that described support assembly is provided with fertilising
Becoming installing rack, described fertilising assembly installing rack is provided with air gun type fertilising assembly；Described air gun type fertilising assembly bag
Including air compressor, high-pressure gas cylinder and the fertilising gun barrel set gradually, described air compressor stores up with high pressure
Being provided with connecting tube between gas cylinder, described connecting tube is provided with valve, sets between described high-pressure gas cylinder and fertilising gun barrel
Having manifold, described manifold to be provided with electromagnetic valve, described electromagnetic valve is connected with electrical control panels；Described fertilising
It is provided with fertilizer delivering pipe between gun barrel and fertilizer box, is arranged over valve with fertilizer delivering pipe junction in described fertilising gun barrel, institute
State and be provided with extension spring between valve and fertilising gun barrel, bottom described fertilising gun barrel, be provided with rubber rollers.
Further, being provided with roller in described fertilizer box, described roller rotates and uses variable frequency switch to control to turn
Dynamic frequency.
The method have the benefit that: the present invention uses airgun principle directly to be squeezed into by granular urea
In mud near rice shoot, it is to avoid fertilizer delivering pipe and mud contacts, i.e. reach deep placement effect, avoid again fertilizer
Pipe operation blocking, trench digging make mud be deposited in the problem near rice shoot, thus realize granular urea deep placement,
Fixed point, quantitative fertilization.
