Description

Local fertilizer drill under a kind of duplex soil
Technical field
The present invention relates to agricultural machinery technological fields, and in particular to be local fertilizer drill under a kind of duplex soil.
Background technique
Agricultural is the growth-development law using animals and plants, and the industry of product is obtained by artificial culture.Agricultural is to mention For the important industry of basic product needed for the support development of the national economy and development.China is large agricultural country, the agricultural production in China Have the characteristics that small single household planting range, plantation landform multiplicity, mechanization are difficult again, it is difficult to popularize mechanization production in the short time.
Fertilising is job category common in agricultural planting, existing fertilization mode mainly have water distribution fertilising, foliage dressing and Three kinds of soil application, water distribution fertilising generally comprises that punching is applied and dropper, advantage are can to impose on crop root, on one side with while apply, flow Lose few, the disadvantage is that dropper equipment cost is high, pours water and be also required to a large amount of water and artificial, and purity to fertilizer and it is water-soluble all There is higher requirement;Foliage dressing advantage is that the utilization rate of fertilizer is high, and effect is fast, especially suitable for the supplement of middle microelement, The disadvantage is that fertilizer nutrient is very pure, security requirement is high, higher water solubility, the higher cost of plant absorption unit nutrient, Therefore, soil application is still presently the most widely applied fertilization mode.
Traditional soil application mode requires manually to dig pit or ditch, and consumes a large amount of physical strength and time, and chemical fertilizer utilizes Phenomena such as rate is not high, easily causes soil hardening.Fertilizer is directly applied the soil near crop root part by fertilising function, can basis The different adjustment fertilizer amount size and fertilization depth of crop specie, and fertilizer applicator has the characteristics that structure is simple, easy to operate, The use of fertilizer applicator can reduce the labor intensity of peasant, improves chemical fertilizer utilization ratio, reduces environmental pollution, reach province it is fertile, it is laborsaving, Time saving, economical effect.Application No. is the Chinese invention patents of 201510856758.X, disclose a kind of apply fertilizer from feeding type and set Standby, intrusion pipe is hollow structure, and the bottom of intrusion pipe is tip, offers fluid hole on the bottom cylindrical face of intrusion pipe, is perfused During pipe opens cave in the soil, soil is easy to blocking fluid hole, so that fertilizer be made to cannot be introduced into soil;Application No. is The Chinese utility model patent of 201820320036 .1 discloses one kind of vegetable planting technology field for rural area single household kind Fertilizer apparatus under the soil of plant, including mixing drum, connecting tube and fertilising pipe, fertilising pipe are inserted into soil course, and fertilizer applying hole is also easy It is obstructed with soil, to break down.
The existing generally existing fertilizer of fertilizer applicator is easy to be obstructed with soil and open cave in the easy blocking of internal pipeline, fertilizer outlet Time and effort consuming in the process, the problems such as being easily damaged fertilizer applicator.
