Abstract

The invention relates to crop straws, in particular to a technology for recycling the crop straws, and belongs to the technical field of agricultural deep processing. By the technology, straws of crops such as rice and wheat, corn and the like are directly or indirectly returned to the field, so that the growth of weeds is inhibited when the straws are returned to the field to increase soil fertility; and the technology also has the effects of storing water and preserving moisture.

Description

A kind of crop stalk recycle utilization

Technical field

The present invention relates to a kind of agricultural crop straw, be specifically related to a kind of agricultural crop straw recycle utilization, belong to agriculture deep process technology field.

Background technology

Crop stalk is a kind of living resources, contains mineral nutrient and organic matters such as nitrogen, phosphorus, potassium, calcium, magnesium, protein, fine little element, lignin.With straw direct returning to farmland and indirect also field, can replenish soil nutrient comprehensively, increase the soil organic matter, improve soil structure, the level that increases fertility of land and crop yield have significant ecology, society and economic benefit.To reduce, utilize method to grasp with careless quantity not enough along with life of farmers in recent years, makes straw burn, leave about that to abandon phenomenon comparatively serious, not only wastes resource, and also contaminated environment influences traffic, is unfavorable for the ecological balance.

Summary of the invention

The objective of the invention is for overcoming the weak point of above-mentioned prior art; A kind of agricultural crop straw recycle utilization is provided; Utilize agricultural crop straws such as rice wheat, corn through direct returning to farmland or indirectly and the field; When returning crop stocks to the field culture fertility, realization suppresses weed growth, the effect of retaining and conserveing soil moisture in addition.

The present invention realizes through following technical scheme: a kind of crop stalk recycle utilization is characterized in that: comprise the steps:

(1) paddy rice, wheat machine are received rotary tillage stubble-cleaning direct returning to farmland: after straw is pulverized in the harvesting of wheat machine; Evenly be spread on the field face to straw, irritate rice transplanting the previous day the shallow water that exceeds surperficial 3cm and macerate one night of system, used sufficient base fertilizer with the rotary tillage of tractor shallow water in second day; Make straw go into mud, then rice transplanting.Straw is pulverized in the harvesting of paddy rice machine, and the grass of pulverizing is saved the field face that evenly is spread on, and adopts machine rotary tillage or ox to plough, and straw is turned over imbed soil, uses sufficient base fertilizer, whole field bedding sowing wheat, or press row and concentrate fertilising, the rape of planting;

(2) straw, corn straw turn over and bury also field: with ploughing a field straw or the suitable ditch dug with a plow place mat tillage pan of corn straw (the oversize pipe nipple that cuts up with a hay cutter into), turn over pile things on successively in fact, apply fertilizer, put in order field sowing wheat then or plant other crops;

(3) indirectly cover and return crop stocks to the field: be exactly between big strain crop row, or before emerging after the little strain seeding crops at ground surface cover crop straw, let rotten the returning crop stocks to the field of nature;

(4) rice stubble rape half no-tillage lid grass field also: the water-break field of drying in the air after the rice harves, do not turn over plough, the line-spacing stay cord spacing of pressing the 2.5-2.8 chi before the transplanting; Use sufficient base fertilizer along rope is concentrated, dig capable skewer soil, make the clay fertilizer mixing; The nest of pressing the 0.5-0.8 chi is apart from two strain transplanting rape seedlings, and rape is transplanted the back at mulching straw in the ranks, and straw will cover even covering completely in the ranks; Can effectively suppress the inter-row weed growth, recruitment that the minimizing chemistry is hoed up weeds or manual work is hoed up weeds.

Advantage of the present invention is: agricultural crop straws such as this techniques make use rice wheat, corn are through direct returning to farmland or go back the field indirectly, suppress weed growth, the effect of retaining and conserveing soil moisture in addition when realizing returning crop stocks to the field culture fertility.

Embodiment

Embodiment,

A kind of crop stalk recycle utilization comprises the steps:

(1) paddy rice, wheat machine are received rotary tillage stubble-cleaning direct returning to farmland: after straw is pulverized in the harvesting of wheat machine; Evenly be spread on the field face to straw, irritate rice transplanting the previous day the shallow water that exceeds surperficial 3cm and macerate one night of system, used sufficient base fertilizer with the rotary tillage of tractor shallow water in second day; Make straw go into mud, then rice transplanting.Straw is pulverized in the harvesting of paddy rice machine, and the grass of pulverizing is saved the field face that evenly is spread on, and adopts machine rotary tillage or ox to plough, and straw is turned over imbed soil, uses sufficient base fertilizer, whole field bedding sowing wheat, or press row and concentrate fertilising, the rape of planting;

(2) straw, corn straw turn over and bury also field: with ploughing a field straw or the suitable ditch dug with a plow place mat tillage pan of corn straw (the oversize pipe nipple that cuts up with a hay cutter into), turn over pile things on successively in fact, apply fertilizer, put in order field sowing wheat then or plant other crops;

(3) indirectly cover and return crop stocks to the field: be exactly between big strain crop row, or before emerging after the little strain seeding crops at ground surface cover crop straw, let rotten the returning crop stocks to the field of nature;

(4) rice stubble rape half no-tillage lid grass field also: the water-break field of drying in the air after the rice harves, do not turn over plough, the line-spacing stay cord spacing of pressing the 2.5-2.8 chi before the transplanting; Use sufficient base fertilizer along rope is concentrated, dig capable skewer soil, make the clay fertilizer mixing; The nest of pressing the 0.5-0.8 chi is apart from two strain transplanting rape seedlings, and rape is transplanted the back at mulching straw in the ranks, and straw will cover even covering completely in the ranks; Can effectively suppress the inter-row weed growth, recruitment that the minimizing chemistry is hoed up weeds or manual work is hoed up weeds.

Claims (1)

1. a crop stalk recycle utilization is characterized in that: comprise the steps:
