Abstract

The invention discloses an organic fertilizing method of returning all wheat straw to field; a complete ditch system is established for autumn sowing wheat seeds, the wheat is sown by adopting strip or band shaped wide-narrow rows, apart from applying fertilizer in sowing season and seedling period, livestock and poultry manure organic fertilizer is applied to wide lines or empty rows of the wheat field in a plurality of periods; rice straw is turned and buried by combining intertill of the wide lines and the empty rows from winter to shooting stage; wheat stubble is kept 25-30cm when the wheat is mechanically harvested, then the rest wheat straw is buried in the wheat field ditches; the wheat field is irrigated, and paddy rice is planted in the empty rows among the wheat stubble, thus forming a band-shaped layout; only a chemical fertilizer is applied as a base fertilizer used in paddy rice plantation and as a tillering fertilizer, and the other base fertilizer adopts livestock and poultry manure organic fertilizer; when the water supply of the paddy field is cut off for field drainage, the wheat straw buried in the field ditch is taken out and distributed in the wide lines or empty rows of the paddy field, 1-4 days before finishing field drainage and rewatering, the livestock and poultry manure organic fertilizer is applied as a panicle fertilizer in the wide lines or empty rows of the paddy field. The organic fertilizing method of returning all wheat straw to field has the advantages of simple operation, and can effectively realize resource recycling of straw and livestock and poultry manure.

Description

Organic fertilizer cultivation method with complete wheat straw returning

Technical field:

The present invention relates to a kind of organic fertilizer cultivation method with complete wheat straw returning.

Background technology:

In the mutual one along the line of the other one so as to plough deeper operation mode of existing wheat rice, be main fertilizer with chemical fertilizer basically, stalk generally adopts method such as burning to handle, and has not only wasted but also contaminated environment.

Summary of the invention:

The object of the present invention is to provide a kind of operation easy, can effectively realize stalk, the recycling organic fertilizer cultivation method with complete wheat straw returning of livestock and poultry dung recovery.

Technical solution of the present invention is:

A kind of organic fertilizer cultivation method with complete wheat straw returning is characterized in that: comprise the following steps: successively

(1) in wheat rice double cropping system rice field, autumn sowing kind wheat is pressed 180～240 centimetres of furrow face widths, 15～25 centimetres of furrow widths, ditch depth is set up complete ditch for 15～20 centimetres, it is 35～40 centimetres that wheat is adopted wide capable range, the narrow row range is 20～25 centimetres a width width of cloth linear or to adopt empty width of cloth band be 35～40 centimetres, wheat width of cloth band is 20～25 centimetres a strip cropping, except that sowing and using seedling stage the chemical fertilizer, in the wide row or the empty width of cloth of wheatland, before sowing, survive the winter the phase, a plurality of periods are used the feces of livestock and poultry fertilizer before and after the jointing, in conjunction with the repeatedly intertillage in the wide row or the empty width of cloth rice straw are turned over to the jointing in the winter time and bury;

(2) staying during the wheat mechanical harvesting highly is 25～30 centimetres wheat stubble, in the remaining wheat straw landfill wheatland ditch;

(3) wheatland is poured water, and arrangement in the alternate empty width of cloth of wheat stubble, fertilising, plantation paddy rice, forms the banded layout of 35～40 centimetres of wide row, 20～25 centimetres of capable layouts of width of narrow row or 35～40 centimetres on empty width of cloth band, 20～25 centimetres on rice width of cloth band;

Base manure when (4) planting except that paddy rice, tillering fertilizer are used the chemical fertilizer, and all the other base manure are used animal dung ash fertilizer; The rice field begins to cut off the water supply when putting the field, landfill wheat straw in field ditch is gone out clearly, intersperses among in the wide row or the empty width of cloth of paddy rice, puts the field and finishes preceding 1～4 day of rehydration, applies animal dung ash fertilizer and make ear manuer in the wide row in rice field or the empty width of cloth.

Operation of the present invention is easy, being based on the mutual cover of zonal rice or wheat form cultivates on the pattern basis, excreta increments such as realization wheat straw total crop return and livestock and poultry are used the organic light simple high efficiency method of fostering and apply fertilizer in rice field of effective combination, realized that effectively agricultural wastes resources such as stalk, feces of livestock and poultry are recycling, the new way of having opened up the organic getting fat fertile soil in rice field.The present invention can make soil plough horizon organic matter and fertility level significantly improve, and the fertilizer amount in rice field reduces 50～70%, and can realize the lasting volume increase of rice wheat.The present invention utilizes wheatland ditch system, realizes the total crop return that wheat straw high-stubble (being ribbon) and landfill field ditch combine.The wheat straw of landfill field ditch utilizes to irrigate during the rice tillering rots, about 35～45 days (be rice field begin to cut off the water supply put the field after) goes out even spreading clearly in the wide row in rice field or the empty width of cloth behind the straw buried channel, empties and the water starch management that field and paddy rice middle and later periods are put in draining is convenient in unimpeded ditch system.The present invention utilizes the wide row in rice field or the empty width of cloth, carries out the farm animal excrement increment and uses.Put the field and finish preceding 1～4 day of rehydration, the fertilizers such as fowl poultry kind ash excrement that apply capacity in the wide row in rice field or the empty width of cloth are made ear manuer, both can promote the big grain of the big fringe of paddy rice, help quickening wheat straw simultaneously and become thoroughly decomposed, establish the fertility basis that back stubble wheat does.

The invention will be further described below in conjunction with embodiment.

Embodiment:

A kind of organic fertilizer cultivation method with complete wheat straw returning comprises the following steps: successively

(1) in wheat rice double cropping system rice field, autumn sowing kind wheat is pressed 180～240 centimetres of furrow face widths, 15～25 centimetres of furrow widths, ditch depth is set up complete ditch for 15～20 centimetres, it is 35～40 centimetres that wheat is adopted wide capable range, the narrow row range is 20～25 centimetres a width width of cloth linear or to adopt empty width of cloth band be 35～40 centimetres, wheat width of cloth band is 20～25 centimetres a strip cropping, except that sowing and using seedling stage the chemical fertilizer, in the wide row or the empty width of cloth of wheatland, before sowing, survive the winter the phase, a plurality of periods are used the feces of livestock and poultry fertilizer before and after the jointing, in conjunction with the repeatedly intertillage in the wide row or the empty width of cloth rice straw are turned over to the jointing in the winter time and bury;
