Abstract
The present invention belongs to a soil fertility improvement in an agricultural technique, which relates to a method for rapidly increasing the soil organic matter of dry-farming land. The present invention uses a rotary tillage machine to directly pulverize root stubble standing on ridges and roots underground within the range of 10 to 12cm in order to flattening field after crops are harvested in autumn before freezing; the stalk of the crops is used as raw materials, compound microbe germ agents are inoculated, and outdoor half pit type fermentation stacking is utilized; turned and stacked stalk is rotten and heated to preserve fertilizers which are dispersed among farming land before ridging in spring. The present invention is favorable for updating soil humus, can keep the balance of the organic matter of soil. And improves soil structure in order to obtain the functions of keeping the land, enhancing fertilization and promoting the beneficial cycle of agricultural ecology.
Description
Technical field
The invention belongs to the improvement of the soil fertility in the agricultural technology field, relate to a kind of method of the quick raising soil organism.
Background technology
Soil organic matter content how much be the important symbol of soil fertility height, but for many years, because Farmland was overused without proper attention to the maintenance of its fertility, the soil organism obviously descends, opening up wasteland the initial stage soil organism as the Heilongjiang Province of China Lanxi County is 6～8%, has now dropped to 3～4%; LiaoNing, China province Tieling County's soil organism has dropped to 1-1.4% in 1996 from the 2-3% of nineteen sixty.
For a long time, vast farmers waits the balance between supply and demand that guarantees the soil organism with application of organic fertilizers such as barnyard manure, green manure always.
Then adopt no tillage system in the U.S., make that on the ground institute's stalk that produces is all and the way in field improves the soil organism, this method is inapplicable in China.
In China, Jin Senlin equals to deliver on the 3rd phase in " corn science " in 1996 " corn on dry land cultivation new breakthrough---whole bar soverlay technique ", article has been introduced and has been covered in the employing anniversary half, 2 years interval all standing technology, reached and to have improved the soil organism 0.05-0.1% every year, volume increase corn 1500Kg/hm
2Effect.
Summary of the invention
The present invention is by machinery, and the microbial fermentation means are handled crop material, make straw-returning, purpose provides a kind of method that improves soil organic matter of dry-farming land content, thereby improves the integrated production capacity in soil, promotes agricultural to be changed to intensive farming by extensive operation.
The present invention is the direct chopping and returning of crop root residue, and crop material is used also field of microbial fermentation high-rate composting.It is characterized in that (1) is that raw material improves the soil organism with crop material.(2) adopt microorganism-decomposing agent to handle crop material.(3) use stubble in field machinery with the crop root residue mincing and returning to the field.Details are as follows for particular content of the present invention:
1, stubble in field: will stand in root stubble on the ridge and underground 10-12cm with the direct chopping and returning of interior root system with rotary tillage machinery before after the crop autumn harvest, freezing, require to guarantee that the stubble-cleaning degree of depth reaches 10-12cm, root stubble chopping length accounts for 80% less than 5cm, 5-10cm accounts for 20%, the leakage rate of cutting is no more than 0.5%, enrich 5% urea simultaneously, to regulate carbon-nitrogen ratio.
2, stalk microbe fermentation high-rate composting: with the crop material is raw material, and the microbe inoculation composite fungus agent adopts outdoor half hole formula fermentation composting.
Main program is: earlier stalk drenched, and moisture about 70%, then it is piled into widely 2 meters, long high 50cm sprinkles one deck feces of livestock and poultry again, adds 0.5% urea more than 2 meters, and field also is precious in 0.3% ratio dilute with water, evenly sprays on it.The used also field treasured of the present invention is a kind of stalk speed that contains tens of kinds high vigor probioticses (strain) composite fungus agent that becomes thoroughly decomposed.According to said method repeat to pile up three layers, after each layer gone back the precious diluent in field in 2: 4: 4 ratio sprinkling, suitably add some water more from bottom to top, cover completely with plastics film, avoid moisture loss, temperature rises to 50 ℃ and keeps turning in 10 days.
3, using of fertilizer: the stalk after the turning is piled 3 meters long, and 2 meters wide buttress become thoroughly decomposed and protect fertilizer, can become thoroughly decomposed fully through 20-30 days.Spread fertilizer over the fields before the ridging in ploughing in spring, per hectare is used 20m
3-30m
3
The present invention helps upgrading agron, keeps soil organic matter balance, and makes the long-term application chemical fertilizer cause the soil that hardens to obtain improvement, has improved Soil structure, reaches the effect of the getting fat of increasing soil fertility, and promotes the Agro-ecology benign cycle.
Embodiment
The present invention implemented in the Wo Pi township, Dehui City, Jilin Province of China morning twilight 6 societies in-calendar year 2001 in 1998, this ground is positioned at Chinese song-Nen plain black earth band south, agricultural development has over one hundred year history, because peasant's predation formula is managed, Farmland was overused without proper attention to the maintenance of its fertility, black earth is degenerated serious, the organic 2.5%-3.0% that has dropped to 1998 from the 3.2%-4.3% of the seventies of soil, annual speed with 0.025% descends, and is badly in need of fertilizing soil.
During enforcement, used also field treasured is produced by TianXing, Xi'an technology ﹠ development Co., product " TX (TianXing)-518 is the field treasured also " by name.
After the autumn harvest in 1998, root stubble in 1.5 hectares of arable lands is smashed also field with rotary cultivator, July in 1999 1.5 hectares of 9450 kilograms of maize straws that produced are used method of the present invention and carry out compost, become thoroughly decomposed fully after 50 days, these fertilizer are applied in 1.5 hectares of arable lands spring in 2000.Apply the fertilizer that becomes thoroughly decomposed of the stalk that produces in 2000 equally in spring calendar year 2001.After the calendar year 2001 autumn harvest, in 1.5 hectares of arable lands, divide at 5 and gather the topsoil soils sample, mix the back and measure the soil organism.Organic content has reached 3.17%, has increased by 0.42 percentage point than 1998 annual content, increases the soil organism 0.21% every year on average.Prove that this kind method is to improve a kind of new way of the soil organism fast.
