Abstract

Disclosed is a corn straw crushing returning method. The corn straw crushing returning method includes: using a combined harvester to harvest corn and crush corn straw after the corn is ripe; performing supplementary application of nitrogen fertilizer after the corn straw is chopped, enriching the nitrogen fertilizer according to the proportion of increasing 1kg of pure nitrogen in each 100kg of straw, and uniformly scattering the enriched nitrogen fertilizer on a field after the corn straw on the field is crushed; using a rotary cultivator to plow once, fully mixing the chopped straw, the fertilizer and surface soil while cutting stubbles; using a large and medium tractor in combination with a furrow plow to deeply plough the straw or use the rotary cultivator matched with the large and medium tractor large than 50 horsepower in rotary tillage after stubble cleaning; using a wheat seeding machine with a disk coulter to sow after the furrow plow deeply ploughs, thoroughly harrows, tightly presses and levels the straw; timely sowing, guaranteeing that crushing rate of seeds is not larger than 0.5%, and furthermore guaranteeing that no sowing leakage phenomenon is caused in the filed, no reseeding phenomenon is caused on the edge of the field, and end breakage rate is not larger than 5%. The corn straw crushing returning method has the advantages of being capable of reducing consumption of manpower and material resources, and achieving the effect of raising soil fertility.

Description

The method in a kind of corn straw smashing also field

Technical field

The present invention relates to agriculture field, particularly relate to the method in a kind of corn straw smashing also field.

Background technology

Giving back field machine for corn stalks tool technology refers to that the maize straw after being gathered in the crops by fruit ear with straw crushing and field-returning machine is pulverized on the spot by required standard, shed on earth's surface equably, makes it to rot to decompose, reaches the technology of culture fertility.

Summary of the invention

Technical problem to be solved by this invention is to provide the method in a kind of corn straw smashing also field.

The present invention solves the problems of the technologies described above by the following technical solutions: the method in a kind of corn straw smashing also field, comprises the steps:

Use combine harvesting corn and crushing maize stalk after step 1, corn maturation, corn knob fringe height is generally not less than 50cm, and lodging degree is less than 5%; The sagging rate of fruit ear is less than 15%; That operation Shi Ge will aim at corn in road is capable, adopts artificial harvesting, take advantage of after harvesting stalk dark green time, use the straw crushing and field-returning machine chopping stalk of tractor in time, after chopping, stalk length is not more than 10cm; Stubble is high is not more than 5cm;

Carry out benefit nitrogen fertilizer application after step 2, stalks cutting, increase the ratio lift-augmented mechanism of 1kg purity nitrogen according to every 100kg stalk, the nitrogenous fertilizer enriched evenly is spread on the field after crushed stalk;

Step 3, with rotovator operation once, while chopping root stubble, crushing straw, chemical fertilizer are fully mixed with surface soil, in order to rotten;

Use the supporting mouldboard plow deep ploughing of large and middle tractor to turn over after step 4, stubble-cleaning and bury stalk, tilling depth is not less than 20cm, or the rotovator rotary tillage using the large and middle tractor of more than 50 horsepowers supporting, and stalk is mixed with soil, harrows thoroughly, town is real, leveling after ploughing;

The deep ploughing of step 5, mouldboard plow is turned over and is buried stalk disease rake thoroughly, after real, the leveling in town, with the wheat seeder sowing of band disk coulter, sowing depth is less than 5cm; After tea is buried in rotary tillage, a gram use rotary tillage fertilizer is sowed, and after planting will suppress consolidation.

Step 6, sowing in time, seed percentage of damage is not more than 0.5%, and field is not more than 5% without broadcast leakage, the edge of a field without replay, end breakage rate.

The invention has the advantages that: the method using corn straw smashing of the present invention also field, can manpower and materials be reduced, and reach the effect of culture fertility.

Embodiment

Below in conjunction with instantiation, the present invention is described in detail; should understand; embodiment is only for illustration of the present invention, instead of for limiting the present invention, any amendment, equivalent replacement etc. made on basis of the present invention is all in protection scope of the present invention.

The method in corn straw smashing also field, comprises the steps:

Use combine harvesting corn and crushing maize stalk after step 1, corn maturation, corn knob fringe height is generally not less than 50cm, and lodging degree is less than 5%; The sagging rate of fruit ear is less than 15%; It is capable that operation Shi Ge will aim at corn in road, fringe loss is fallen to reduce, adopt artificial harvesting, when taking advantage of stalk viridescent (optimum water content more than 30%) after harvesting, the straw crushing and field-returning machine chopping stalk that timely use tractor (more than 50 horsepowers) is supporting, after chopping, stalk length is not more than 10cm; Stubble is high is not more than 5cm, and anti-leak-stopping is cut;

Carry out benefit nitrogen fertilizer application after step 2, stalks cutting, increase the ratio lift-augmented mechanism of 1kg purity nitrogen according to every 100kg stalk, the nitrogenous fertilizer enriched evenly is spread on the field after crushed stalk;

Step 3, with rotovator operation once, while chopping root stubble, crushing straw, chemical fertilizer are fully mixed with surface soil, in order to rotten;

Use the supporting mouldboard plow deep ploughing of large and middle tractor to turn over after step 4, stubble-cleaning and bury stalk, tilling depth is not less than 20cm, also can use the rotovator rotary tillage that large and middle tractor (more than 50 horsepowers) is supporting, stalk is mixed with soil, harrow after ploughing thoroughly, town is real, leveling.By ploughing, gland, eliminate the soil caused because of stalk and make somebody a mere figurehead, for sowing creates conditions;

The deep ploughing of step 5, mouldboard plow is turned over and is buried stalk disease rake thoroughly, after real, the leveling in town, with the wheat seeder sowing of band disk coulter, sowing depth is less than 5cm; After tea is buried in rotary tillage, a gram use rotary tillage fertilizer is sowed.After planting consolidation will be suppressed.

Step 6, sowing in time, seed percentage of damage is not more than 0.5%, and field is not more than 5% without broadcast leakage, the edge of a field without replay, end breakage rate.

Claims (1)

1. the method in corn straw smashing also field, is characterized in that: comprise the steps:
