Abstract
The utility model relates to the technical field of agricultural production equipment and in particular relates to a rice spot, quantitative and deep fertilizing device. The rice spot, quantitative and deep fertilizing device comprises a transplanter, a rack assembly, a fertilizer tank fixing frame and a fertilizer tank, wherein the rack assembly is provided with a fertilizing assembly mounting frame, and the fertilizing assembly mounting frame is provided with an air gun type fertilizing assembly. According to the rice spot, quantitative and deep fertilizing device, as large granular urea is directly shot into mud near seedlings by adopting the principle of an air gun, a fertilizer pipe is avoided from being contacted with the mud, so that the deep fertilization effect is reached, the problem that the mud stacks near the seedlings due to fertilizer pipe operation blockage and trenching is avoided, and deep, spot and quantitative fertilization of the large granular urea is realized.
Description
Technical field
The utility model 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%, at present China rice field single cropping nitrogen fertilizer amount average out to 180kg/hm
2, than world's unit are consumption, exceed 75%.After Irrigated paddy field applied nitrogen, owing to running off and seepage effect etc. causes loss of nitrogen fertilizer in the volatilization of ammonia in soil-water system, denitrification, surface, so 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.Compare 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.Patent " 93246725.3 " fertilizer spreader for rice transplanter for example, 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 guarantee, has affected paddy rice yield per unit area and has improved.Patent " 200820089772.7 " gas-blowing type side subsoil application paddy rice transplanter and for example, 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.
