The present invention compared with prior art, has following beneficial effect:
Because the present invention adopts the cutter assembly that loosens the soil, the knife bar that loosens the soil of two or single high-speed rotation, the loosing soil of sowing row simultaneously the root stubble chopping of impact sowing; Effectively avoid stalk or weeds long when more, there is the phenomenon of stopping up, the furrow plough that more can not apply fertilizer winds up phenomenon, simultaneously the cutter that loosens the soil of High Rotation Speed is first about to soil and is drawn pine, guarantee that fertilising furrow plough can normally work, in addition, the cutter that loosens the soil of rotation, required power more directly loosens the soil less with colter, energy-saving effect is obvious; Preposition soil treatment device, if when rotovator, carries out Soil Straw pulverizing, weeding, is beneficial to soil moisture conservation except worm's ovum, loose surface soil.Rotary tillage severity control is 30-50mm, and the benefit of subsoiling: soil subsoiling is one of yield-increasing technology measure that state key is promoted in recent years, and application subsoiling technology is thoroughly broken hard tillage pan, make the soil structure obtain reasonably optimizing, thereby reached the object of cost-saving synergistic, increasing both production and income.
* improve the water-holding capacity of soil.Subsoiling position loosing soil, is conducive to rain infiltration, and after subsoiling, general soil surface roughness increases in addition, can hinder rainfall runoff, extends the rain infiltration time, therefore under certain condition can many retainings.
* improve soil structure.The soil structure that forms actual situation after subsoiling and deposit, is conducive to the gas exchange of soil, promotes the activation of microorganism and the decomposition of mineral matter, improves soil fertility.
* after soil subsoiling, the solvability of fertilizer be can increase, thereby the volatilization of chemical fertilizer and the availability of loss raising fertilizer reduced.
* crops are received some necessary operations as sowing, spray medicine, results, transport etc. can cause certain soil compaction from planting to, utilize Subsoiler can eliminate because machine enters the soil compaction that ground operation causes.
* reduce rainfall runoff, reduce soil water erosion.Subsoiling is not turned over a layer soil layer, makes residue, stalk, and weeds major part is covered in earth's surface, is conducive to water conservation, reduces wind erosion, can receive again more rainwater, can also delay the generation of runoff, weakens the intensity of runoff, reduces water and soil loss, effectively soil protection.
* after subsoiling, can reduce rotary tillage number of times (general rotary tillage one time), reduce the cost.
Pine soil depth reaches after 200-300mm, can carry out fertilizer deep placement and just execute, the benefit of deep placement: traditional fertilization method follows the line of least resistance and dislikes trouble in the time giving Crops in Applying Fertilizer, chemical fertilizer is sprinkling upon to earth's surface, field or shallow executing at the side of the seed, these two kinds of fertilizing methods can cause fertilizer efficiency heavy losses, increased the weight of again environmental pollution, crops also can not get corresponding nutrient demand, cause crop failure simultaneously.Therefore, change this bad fertilizing method, accomplish fertilizer deep placement, so not only can reduce chemical fertilizer volatilization loss, improve utilization rate of fertilizer, be conducive to crop and absorb better, can alleviate again environmental pollution, reach the effect of increasing both production and income simultaneously.According to test, after nitrogenous fertilizer deep placement, average utilization can bring up to 40% by 30%, and phosphorus potash fertilizer deep placement can reduce the loss of wind erosion, promotes Crop, extends fertilizer efficiency, and rate of growth generally can reach 5%～15%.
