Abstract
The invention provides a straw and biogas slurry synchronous returning method and a machine, and belongs to the farmland preparation technology and machines. The method includes the steps that crop straw and stubbles in fields are smashed and scattered on the fields, biogas slurry generated after anaerobic fermentation of biomass is sprayed on the smashed straw and the stubbles, soil is turned over and tilled by means of a moldboard plow, the smashed straw, the smashed stubbles and the biogas slurry are buried in and covers the soil together, and finally the surfaces of the fields are compacted and leveled. The machine comprises a machine frame assembly, a three-point suspension assembly, a straw and stubble smashing cutter shaft assembly, a walking wheel assembly, a biogas slurry spraying assembly, a moldboard plow assembly and a compacting assembly, wherein the three-point suspension assembly, the straw and stubble smashing cutter shaft assembly, the walking wheel assembly, the biogas slurry spraying assembly, the moldboard plow assembly and the compacting assembly are arranged on the machine frame assembly. The method is simple in process, the straw returning effect is good, quality is high, soil restoration is facilitated, work cost is low, the machine is reasonable in structure, the use requirement for straw and biogas slurry synchronous returning is met, work efficiency is high, and usage is reliable.
Description
Technical field
The invention belongs to farmland tillage operation technology and facility, relate generally to a kind of operational method to stalk also field synchronous with natural pond liquid and facility.
Background technology
China is a large agricultural country, the agricultural crop straw that annual generation is a large amount of, and current straw-returning is a kind of important way of straw utilization, is the important measures of agricultural sustainable development, has good economic benefit, ecological benefits and social benefit.Although straw-returning is a kind of straw utilization mode preferably, but because stalk is formed primarily of lignin, cellulose and hemicellulose, and C/N is higher, moisture is lower, and then cause also behind field the stalk degradation speed that rots slower, be unfavorable for the utilization of stalk, and affect sowing and the growth of crops of lower season, the bottleneck problem becoming the technology application of restriction straw-returning and promote.The problems referred to above, in areas such as the Heilungkiang of northern China, Jilin, Inner Mongols, due to dry in autumn, temperature is low, and the moisture content of agricultural crop straw is lower, and its lignification, fibrosis are more serious, and degraded of also rotting behind field is more difficult.
Summary of the invention
Object of the present invention is exactly for above-mentioned prior art Problems existing, in conjunction with the actual demand of straw chopping and returning operation, study a kind of stalk also field operational method and facility synchronous with natural pond liquid, reach the object improving straw-returning operation quality and effect, quickening straw decomposition speed.
The object of the present invention is achieved like this: a kind of stalk also field operational method synchronous with natural pond liquid comprises the following steps:
1., utilize stalk and the fragmentation of root stubble to shed after the agricultural crop straw and root stubble that are positioned at field complete broken processing by workover rig, shed in field on the surface;
2., utilize natural pond liquid spray appliance to be sprayed by the natural pond liquid produced after biomass anaerobic fermentation and be positioned at field on the surface and on the agricultural crop straw be broken and root stubble;
3., utilize mouldboard plow assembly to carry out the flat work of turning in soil, utilize flat upturned soil of turning over generation the broken stalk after having sprayed natural pond liquid, root stubble to be buried and cover in soil;
4., utilize suppression apparatus for work to suppress compacting leveling operation to surface, soil, field comprehensively, make soil to stalk, root stubble bury tighter, ensure and improve stalk and root stubble degradation speed and effect in soil.
Stalk also field work tool synchronous with natural pond liquid comprises support assembly, the forward upper and bottom of described support assembly are installed trifilar suspension assembly and stalk and root stubble crushing cutter shaft assembly respectively, two road wheel assemblies are fitted on support assembly left and right side respectively, on described support assembly, are positioned at stalk and root stubble crushing cutter shaft assembly rear and configure successively from front to back and install natural pond liquid and spray assembly, mouldboard plow assembly and suppress assembly.
The problem that the inventive method is low for moisture during straw-returning and C/N is high, for reaching the object regulating stalk moisture and C/N, adopt the natural pond liquid after wet type anaerobic fermentation as spray agent, utilize moisture in the liquid of natural pond high, be rich in ammonia nitrogen etc. be beneficial to the nitrogen of microorganism utilization and there is certain sterilizing function, it is a kind of characteristic of extraordinary liquid bio-organic fertilizer, join in straw-returning process simultaneously and execute moisturizing and the benefit nitrogen process that natural pond liquid just once can complete stalk, in reduction straw-returning expense, accelerate and behind field while straw degradative speed, also the utilization ways of natural pond liquid after anaerobic fermentation has been widened further, this stalk also field work tool synchronous with root stubble one-time continuous can complete the pulverizing of stalk and root stubble, humidification, benefit nitrogen and returning and suppresses, accelerate the decomposition speed of stalk, also reduce the dust generation in the process of field, and realize the deactivation of part stalk germ, have rational in infrastructure, operation effectiveness good, operating efficiency is high, use is reliable, be conducive to the increase of the recovery of soil aggregate and nutrition, when alleviating operation to the pollution of environment, feature that operating cost is cheap.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present invention is described in detail.A kind of stalk also field work tool synchronous with natural pond liquid comprises support assembly 1, the forward upper and bottom of described support assembly 1 are installed trifilar suspension assembly 3 and stalk and root stubble crushing cutter shaft assembly 4 respectively, two road wheel assemblies 2 are fitted on support assembly 1 left and right side respectively, on described support assembly 1, are positioned at stalk and root stubble crushing cutter shaft assembly 4 rear and configure successively from front to back and install natural pond liquid and spray assembly 5, mouldboard plow assembly 6 and suppress assembly 7.
During operation, the stalk on stalk field-returning machine tool synchronous with natural pond liquid and root stubble crushing cutter shaft assembly 4 are shed in field on the surface after the agricultural crop straw and root stubble that are positioned at field being completed broken processing; Continue you utilize natural pond liquid spray assembly 5 by living beings wet type anaerobic fermentation after the natural pond liquid that produces spray and be positioned at field on the surface and on the agricultural crop straw be broken and root stubble; Utilize mouldboard plow assembly 6 to carry out the flat work of turning in soil, utilize flat upturned soil of turning over generation the broken stalk after having sprayed natural pond liquid, root stubble to be buried and cover in soil; Utilize suppression surface, soil, assembly 7 pairs of fields to suppress compacting leveling operation comprehensively, make soil to stalk, root stubble bury tighter, ensure and improve stalk and root stubble degradation speed and effect in soil.In research practice, prove by going back separately field, the stalk moisturizing comparative trial that also field mode is gone back in field and stalk also three kinds, field synchronous with natural pond liquid to maize straw, also field is after 60 days, the soil organic matter content of each group improves 1.26%, 3.18% and 4.37% respectively, and straw degradative rate is respectively 21%, 33% and 58%.Stalk and natural pond liquid are gone back field group indices simultaneously and are all better than other two groups.
