Description
Technical field
The invention belongs to corn stover processing technology fields, and in particular to a kind of corn stalk powder rake total crop return technique.
Background technique
Crop material is the significant by-products of crops, the annual agricultural crop straw yield in China up to as many as 6.2 hundred million tons, wherein
Corn stover quantity accounts for 60-70%, and so many crop material, only 20-30% is utilized every year, the main reason is that not having
Have and finds an effective utilization ways to stalk.Stalk mainly has a purposes of several respects as a kind of resource: feed, fuel,
Fertilizer and part light industry raw material.Since agriculture district aquaculture is undeveloped, feed conversion is less；Raw material of industry utilization is also very limited, adds
In recent years as economic rapid growth, the bavin stove in rural area are cancelled substantially, no longer do fuel, the benefit of most of stalk with stalk
Using approach is as fertilizer returning to the field, i.e., by after corn straw smashing, the corn stover of crushing is embedded in ground by site preparation after raking the soil level, this
To culture fertility, agricultural production sustainable development is promoted to have positive effect.For this effective measures of straw-returning, peasant, which early has, to be recognized
Know, but be difficult to popularize in an all-round way, it is important to none simple and easy to do, saving of labor, labour-saving returning to the field method.Especially corn stover,
Stalk wall is hard, and plant is higher, and biomass is big, it is difficult to returning to the field.Traditional stack retting decomposition into field method, because time-consuming, arduously, returning to the field effect
Rate is low, it is difficult to promote；Returning to the field is mechanically pulverized, operating cost is high, and the enthusiasm that peasant uses is not high；So most of corn stover
Cannot utilize returning to the field, and abandoning in the roadside edge of a field, commit to the flames.
Summary of the invention
In order to solve the above technical problem, the present invention provides a kind of corn stalk powders to harrow total crop return technique.
The present invention is achieved by the following technical solutions.
A kind of corn stalk powder rake total crop return technique, including following operating procedure:
(1) stalk crushes: when this season corn variety is early ripening maize kind, when harvest using cropper to corn stover into
Row crushes, and does not need to be crushed with straw counters-field set again before site preparation；When this season corn variety is Mid-late ripening corn variety, harvest
Shi Liyong cropper tentatively crushes corn stover, then after carrying out sunning processing to it, using straw counters-field set to stalk
It carries out second to crush, smashed corn stover is uniformly shed in field face；
(2) site preparation: carrying out site preparation with combined soil preparing machine, using the loose smooth soil of subsoiling rake teeth, mixed straw and root stubble；
The stubble of upper soll layer is cut and arranged using notched disk disk, and the corn stover of control corn stover total amount 25-40% is exposed at
Soil surface, remaining corn stover are mixed with soil, depth of soil preparation 40-50cm；
(3) rake the soil level: first being raked the soil level once with heavy duty harrow, then with gently rake the soil level once, when raking the soil level operating direction will with plough at big
In 30 ° of acute angle, forbid along rake；Rake the soil level operation when to wear leveller, rake drag combines multiple operation；
(4) ridging: rake the soil level it is smooth after, ridger ridging；
(5) sow: spring in next year carries out corn seeding when 5 centimetres of depth of soils ground temperature is stablized by 8 DEG C；
(6) it applies fertilizer: applying fertilizer to the subsoil when sowing primary, it is primary in corn big bell mouth stage Nitrogen Top Dressing.
Specifically, in above-mentioned steps (1), the time for drying processing is 5-10 days.
Specifically, in above-mentioned steps (3), depth when heavy duty harrow is raked the soil level is 16-18cm, and the depth gently raked the soil level is 8-
10cm。
Specifically, in above-mentioned steps (4), when ridging, furrow depth is 18-25cm, and furrow width is 15-20cm.
Specifically, in above-mentioned steps (6), when applying fertilizer to the subsoil, the dosage of urea is 150-170kg/hm2, phosphorus pentoxide
Dosage is 85-95kg/hm2, the dosage of potassium oxide is 85-95kg/hm2, when Nitrogen Top Dressing, the dosage of urea is 75-85kg/
hm2。
From the above technical scheme, it can be seen that the beneficial effects of the present invention are:
A kind of corn stalk powder provided by the invention harrows total crop return technique, easy to operate, time saving and energy saving, at low cost, has
Effect solves in the prior art, and when maize straw, straw decomposing is slow, the technical issues of being also easy to produce high temperature, cause runt seedling；
Soil can be improved, soil fertility is increased, prevents the generation of second stubble crop pest and disease damage.
Specific embodiment
The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.Reality used in the examples
The condition of applying can be for further adjustments according to the condition of producer, and unaccounted implementation condition is usually conventional laboratory conditions.
For SOIL CARBON AND NITROGEN after straw directly returning to field under corn in Northeast China continuous cropping system than unbalance, nutrients release lag etc.
Problem is implemented in the Northeast using method of the invention, and completely new returning total stalks into fields npk nutrient optimization is formed
Administrative skill mode.
