Abstract
The present invention provides method for tilling corn land, and features that high stubble is left while harvesting corn, stubble is cleared and ridge in seeding state is formed in the autumn, the land is not further tilled before seeding in the next spring, and intertillage is completed during top dressing, with the said process being repeated year after year. The said tilling method, compared with available tillage method, has organic matter in the surface soil increased by 0.30-0.80 g/kg, soil water content in spring raised by 0.5-2.0 % and corn yield raised by 5-10 %.
Description
Technical field
The invention belongs to the crops farming technique, particularly corn conservation tillage method.
Background technology
In existing tillage and cultivation, the country economically developed, that weather conditions are suitable, agricultural production all realizes mechanization, the combination of agricultural machinery agronomy, the key technology of agriculture requirement realizes by agricultural machinery.
The existing method of soil preparation in China the Northeast: the one, maize straw is cut off in autumn harvest, turns over, rakes and broadcast into the even ridge of 60-70cm; Second kind is that two ploughs behind the stubble-cleaning (or three plough rivers) become the even ridge of 60-70cm.The main drawback of these two kinds of methods is that cargo handling operation is many, cost is high, and most of stubble-cleanings do not become the ridge simultaneously, or becomes the ridge not suppress, and autumn, two seasons of spring repeatedly wholely just can reach the sowing state, and soil moisture is scattered and disappeared in a large number, has increased the weight of damage caused by a drought; Also field difficulty of the stalk of enforcement safety is arranged again, do not execute under the fertile condition of farming, still belong to predation formula planting patterns current.It is too much that number of times is rolled in the field during mechanical work, and the bulk density of soil increases, and the ability of resisting natural disasters is low, the not high shakiness of output.Labour intensity is big during from the animal power operation, and labor productivity is low.
Summary of the invention
The present invention is a kind of improvement to existing method of soil preparation, stays the high batch of technical measures that adopt the whole ground of high stubble autumn that goes out during harvest corn, reaches the sowing state once wholely, has reached and has reduced the purpose that soil moisture is scattered and disappeared.
The objective of the invention is to increase soil fertility from protection soil resource continuous utilization, the development sustainable agriculture is set out, and solves existing cultivated method soil fertility and descends and the serious drawback of moisture loss, and a kind of corn high batch autumn method of soil preparation that goes out is provided.
The invention provides a kind of cultivated method of soil preparation of corn, it is characterized in that: corn stays high stubble during 1 year results, carries out whole ground of autumn, knocks out high stubble, and ridging suppression simultaneously reaches the sowing state; Do not put in order ground 1 year spring, directly carry out precision drilling on the ridge that is become on 1 year whole ground, the phase of topdressing intertills in the ranks, still stays high stubble during autumn harvest, carries out the autumn to knock out high batch of one-tenth ridge wholely; The direct precision drilling corn in the ranks in still whole ground in the 3rd year spring in 1 year, the phase of topdressing intertills in the ranks, still stays high stubble during autumn harvest, carries out the autumn to knock out high batch of one-tenth ridge wholely; So carry out farming repeatedly between year border.
The height of wherein said high stubble is 20-30cm; The degree of depth of described intertillage is 18-25cm.
Further, the kind method for planting in 1 year is the plantation of even ridge, and the row spacing of wherein said even ridge plantation is 65cm; Can also go out high batch with general stubble cleaner.
By the corn of the present invention high stubble autumn entire technique that goes out, realized also field of stalk safety, lie prostrate intertillage in conjunction with topdressing and break tillage pan, create the topsoil soils reservoir, done and protected " three water ": water storage in summer, autumn water conservation, water saving in spring, need not sit water during sowing, improved the natural precipitation utilization ratio greatly, realize that broken stubble rots to go back the field, increase the soil organic matter, culture fertility naturally, make the land resources continuous utilization.By reducing whole ground number of times, avoided soil moisture to scatter and disappear, to accomplish once to sow and save seedling from damage, seedling is neat, seedling is strong.Adopt precise sowing, reduced production cost significantly, improved economic benefit.
Through experimental test, the corn of the present invention high stubble autumn method of soil preparation that goes out compares with the existing method of not staying whole ground of high stubble spring, the organic average annual 0.30-0.80g/kg that improves of 0-40cm topsoil soils, spring, soil moisture content improved 0.5-2.0 percentage point, survival rate of seedlings improves 5-10%, and output improves 5-10%.
