A kind of stubble, the high-efficient treatment method of straw-returning, its step includes:
One. stubble in field: gathering in crop when, the height of crop root residue is retained in 15cm-20cm；When soil moisture at 25%-30% when, soil and crop root residue are ploughed shallowly, the shallow plowing degree of depth is 8cm-12cm;While shallow plowing, every mu of Calx executing 30-40kg；After shallow plowing, according to the nitrogen phosphorus mass ratio of 3:1, every mu of nitrogen and phosphorous fertilizer executing 15-20kg；Deep ploughing soil and crop root residue, the deep ploughing degree of depth is 15cm-26cm；By the diameter segment crushing more than 8cm, then soil surface is raked;
Gathering in crops when, root stubble is typically all retained in soil, but owing to burning circulation and the absorption being unfavorable for nutrition, so needing to shred root stubble, and mixing with nitrogenous fertilizer and phosphate fertilizer, accelerating the decomposition of root stubble, the reduction promoting nutritional labeling and absorption.
Two. straw-returning:
1) direct returning to farmland: straw cut up with a hay cutter broken or smash with disorderly grass machine, a length of 8cm-16cm after smashing；Being spread on face, field equably by cutting up with a hay cutter straw that is broken or that smash, every mu puts into straw 150-250kg；Every mu of carbamide executing 2-7kg；When soil moisture content 25%-30%, straw is ploughed under in the soil layer of 12cm-15cm, allow straw and carbamide puddle in topsoil；Being drained by the water of soil surface, allow soil surface expose in atmosphere, and once poured water every 5-10 days, because under flooding condition, straw is more prone to carry out decomposition, so the water content that Soil conservation to be allowed is suitable, promotes the carrying out decomposed；
Simple to operate, the low cost of direct returning to farmland, can first put into field and decomposes, discharge nutriment in advance other straws are degenerated when, and also field is spaced apart with making compost, and forms a stereovision, the absorption of instant nutrient.
2) make compost also field: the crushed stalk that remained by direct returning to farmland or be chopped into 3cm-6cm length, so can reduce the volume of single straw, conveniently become thoroughly decomposed；In the 3-4 month, the Animal fecal pollution of the straw of 7-10 part, the night soil of 1-4 part and 2-8 part is sufficiently carried out mix and blend；Mixture after stirring is watered sufficient water so that the water content in mixture, at 60%-70%, so can strengthen the activity of microorganism, accelerate the speed become thoroughly decomposed；Hot water is irrigated animal wastes so that it is temperature is more than or equal to 40 DEG C；Caulis et Folium Oryzae is piled a pile, and lights, by animal excreta toilet cover on stack of rice straw；By mixture in layer cover in animal wastes, form a fermentation heap, heap height 1.5m-2.5m, and on fermentation heap, cover plastic sheeting;Persistently fermentation heap is heated, and the temperature of heating controls at 50 DEG C-70 DEG C, owing to microorganism has specific living environment, the height of temperature directly affects the activity of microorganism, time between 50 DEG C-65 DEG C, the activity of microorganism is optimal, the decomposition of straw can be accelerated, pathogenic bacteria, worm's ovum can be killed again simultaneously, reduce the volatilization of ammonia, when temperature more than 70 DEG C or less than 50 DEG C time, the activity of microorganism can reduce；Ferment 7-10 days, and when the temperature of fermentation heap is at 60 DEG C-65 DEG C, auxiliary fertilizer is covered on described fermentation heap, then ferments, when the temperature of fermentation heap maintains 60 DEG C-65 DEG C, illustrate that fermentation heap has been decomposed；Every 5-8 days, fermenting the most again, after continuing 3-4 time, form compost made of stalks, the compost made of stalks sent out has black, random, smelly feature, has black juice and ammonia stink, soft time wet, flexible, the most crisp time dry, is easily broken；Execute compost made of stalks 1000kg-1800kg and compound fertilizer, then soil is carried out weeding of deep ploughing, finally pours water for every mu, owing to the carbon nitrogen content in straw is the highest, the highest carbon-nitrogen ratio arises that Denitrification in straw putrefaction process, and microorganism absorbs the quick-acting nitrogens in soil, quick-acting nitrogens required for crops are seized, seedling is made to turn to be yellow, poor growth, it is unfavorable for nurturing staff, therefore, while straw-returning, to coordinate and apply chemical nitrogen fertilizer, keep the rational carbon-nitrogen ratio of straw.
Owing to fresh straw can produce various organic acid, effect toxic to crop root in digest process, therefore, when carrying out straw-returning in the acid soil with poor air permeability, appropriate Calx should be applied, neutralize the organic acid produced, help the absorption of nutrition.
The composition of described auxiliary fertilizer and ratio be: the horsehit of 10-15 part, the rabbit excrement of 4-8 part, the chicken manure of 2-5 part, the night soil of 5-10 part, the Calx of 10-25 part, the ammonium hydrogen carbonate of 15-25 part, the ammonium sulfate of 5-10 part, the ammonium chloride of 4-8 part and the carbamide of 10-15 part.
The composition of described compound fertilizer and ratio be: the Calx of 15-25 part, the ammonium hydrogen carbonate of 5-12 part, the ammonium sulfate of 5-10 part, the ammonium chloride of 5-10 part, the ammonia of 10-15 part, the sodium nitrate of 2-5 part, the ammonium nitrate of 4-10 part, the carbamide of 10-15 part, the fishbone powder of 15-20 part, the calcium magnesium phosphate of 5-10 part and the calcium superphosphate of 4-10 part.
Root stubble of the present invention, the high-efficient treatment method of straw-returning provide the benefit that:
1. straw-returning can supplement soil nutrient: crop material contains certain nutrient and cellulose, hemicellulose, lignin, protein and ash element, existing more organic matter, there are again the nutrients such as nitrogen, phosphorus, potassium, if straw being transported from field or burning, so remain in the Organic substance in soil and be less than 10%, thus cause the decline of soil fertility.
2. straw-returning promotes microbial activities: straw-returning adds mass energy material to soil microorganism, all kinds of micro organism quantities and enzymatic activity increase the most accordingly, this has speeded up the decomposition to organic substance and the conversion of mineral nutrient, make the nitrogen in soil, phosphorus, the elements such as potassium increase, the effectiveness of soil nutrient also increases, additionally, the cellulose produced after microbial decomposition converts, lignin, the black colloid substances such as polysaccharide and humic acid, there is the ability of bonding grogs, organic Yu inorganic complex is formed with clay mineral, promote Zinc fractions crumb structure, volume weight of soils is made to alleviate, increase water in soil, fertile, gas, the coordination ability of heat, improve soil water-retaining, fertilizer conservation, the ability of fertilizer, improve soil physical and chemical property.
3. straw-returning can reduce fertilizer application amount: the nitrogen that crop is absorbed essentially from the original nitrogen in soil, only accounts for 23%-24% from chemical fertilizer, so, straw-returning is the fabulous way making up chemical fertilizer life-time service defect.
4. straw-returning can be improved the ecological environment: crop straw burning not only results in contaminated air, affects traffic, upper soll layer coking etc., but also can affect agroecological environment, it is impossible to twice laid.
