Abstract
The invention relates to the technical field of agricultural production equipment, and concretely relates to a fixed-point quantitative deep fertilizing device for rice, the fixed-point quantitative deep fertilizing device for rice comprises a transplanter, a frame assembly, a fertilizer case mounting bracker and a fertilizer case, a fertilizing assembly mounting rack is arranged on the frame assembly, and an air gun type fertilizing assembly is arranged on the fertilizing assembly. According to the invention, an air gun principle is employed for directly injecting large granule urea in slurry near the seedling, contact of a fertilizer conveying pipe and the slurry are avoided, so that deep fertilizing effect is reached, and the problems of obstruction of a fertilizer discharging pipe and accumulation of slurry near the seedling due to trench digging can be solved, and deep fertilizing and fixed-point quantitative fertilizing of large granule urea can be realized.
Description
Technical field
The present invention relates to agricultural production equipment technical field, is a kind of paddy rice site-directed quantitative deep fertilizing device specifically.
Background technology
Paddy rice is one of topmost cereal crops of China, and its gross yield accounts for 1/2 of national total output of grain, and its cultivated area accounts for 1/5 of the world.In paddy ecosystem, nitrogen is again the critical limitation macroelement of Rice Production, is also the enormous motivation that the mankind improve output.China recent years Monitoring of Paddy Rice Plant Area accounts for the world 20%, and nitrogen fertilizer amount accounts for world's paddy rice nitrogen fertilizer amount 37%, and China rice field single cropping nitrogen fertilizer amount average out to 180kg/hm2, exceeds 75% than world's unit are consumption at present.After Irrigated paddy field applied nitrogen, because volatilization, denitrification, surface loss and the seepage effect etc. of ammonia in soil-water system cause loss of nitrogen fertilizer, therefore utilization rate of nitrogen fertilizer is relatively on the low side.After nitrogenous fertilizer face is executed, in the surface water of rice field, ammonium nitrogen concentration increases, and pH value rises, thereby causes the volatilization loss of ammonia.Nitrogenous fertilizer deep placement is to improve the most effective approach of waterflooding rice field utilization rate of nitrogen fertilizer.Compared with traditional top application method, nitrogenous fertilizer deep placement can not only reduce the loss of nitrogen, and can increase output.Therefore, nitrogenous fertilizer deep placement often can obtain higher the Agronomic Use Efficiency.Large granule urea adopts the method for deep placement, and its suitable nitrogen fertilizer amount is 76%～93% of traditional fertilization method requirement optimum dose.
China's rice mechanical transplanting area expands rapidly at present, in the machine transplanting of rice, deep application of fertilizer is entered near rice shoot, makes fertilizer slowly discharge and meet paddy growth demand, realizes the object of rice mechanical transplanting and fertilizer mechanical deep fertilizing.The existing research and development of the method for equipped mechanical deep fertilizing fertilizer and equipment on rice transplanter at present.For example patent " 93246725.3 " fertilizer spreader for rice transplanter, this device is in actual job, mud often stops up defertilizing opening, make can not apply in the paddy field soil of rice seedling sidepiece by the chemical fertilizer of chemical fertilizer flow by gravity, fertilizing amount can not ensure, has affected paddy rice yield per unit area and has improved.And for example patent " 200820089772.7 " gas-blowing type side subsoil application paddy rice transplanter, gas-blowing type side subsoil application paddy rice transplanter is to cover blowning installation of the technical increase of mud at trench digging, adopts gas that fertilizer is blown out from fertilizer delivering pipe, avoids defertilizing opening to stop up.Although reach the problem of eliminating and avoiding the operation of paddy field rice transplanter side deep fertilizing pipe to stop up, but also need to utilize plough trench digging, can cause like this rice shoot annex mud to pile up, thereby the degree of depth of rice transplanting is deepened, affect machine transplanting of rice quality, the effect of ditching in mud bad simultaneously, is difficult to the deep fertilizer spraying effect that reaches real.
Summary of the invention
The object of the invention is the problem existing for above-mentioned technology, a kind of paddy rice site-directed quantitative deep fertilizing device is provided.
For achieving the above object, the technical solution used in the present invention is: a kind of paddy rice site-directed quantitative deep fertilizing device, comprise rice transplanter, support assembly, fertile case fixed mount and fertile case, described support assembly is provided with fertilising assembly installing rack, and described fertilising assembly installing rack is provided with air gun type fertilising assembly; Described air gun type fertilising assembly comprises the air compressor, high-pressure gas cylinder and the fertilising gun barrel that set gradually, between described air compressor and high-pressure gas cylinder, be provided with tube connector, described tube connector is provided with valve, between described high-pressure gas cylinder and fertilising gun barrel, be provided with manifold, described manifold is provided with magnetic valve, and described magnetic valve is connected with Electronic Control panel; Between described fertilising gun barrel and fertile case, be provided with fertilizer delivering pipe, in described fertilising gun barrel, be provided with valve with top, fertilizer delivering pipe junction, between described valve and fertilising gun barrel, be provided with extension spring, described fertilising gun barrel bottom is provided with rubber rollers.
Further, in described fertile case, be provided with defertilizing wheel, described defertilizing wheel rotates and adopts frequency conversion switch control rotational frequency.
Useful technique effect of the present invention is: the present invention adopts airgun principle that granular urea is directly squeezed near mud rice shoot, avoid fertilizer delivering pipe to contact with mud, reach deep placement effect, avoid again defertilizing tube operation obstruction, trench digging to make mud be deposited near the problem of rice shoot, thereby realize granular urea deep placement, fixed point, quantitative fertilization.
