Abstract
A method for soil levelling in large area field includes such steps as ploughing field, planing and raking soil, ridging to form ridge-bordered beds and scraping level within every bed. For said ridging step, various contour lines are measured and marked at first, and then the soil is ridged on contour lines. The level difference between adjacent contour lines is 3-5 cm and the zoned area enclosed by adjacent contour lines is 500-100 sq.m. If water is poured in beds after mecanically levelled, water surface is used as level measuring. It features high effect on soil levelling.
Description
The present invention relates to a kind of method of soil preparation, use when being used for large tracts of land plot rice cultivation.
Because the characteristic of paddy rice on cultivation is very high to the requirement of rice field flatness, the horizontality and the crop on ground are closely related in the same furrow, so seedbed preparation becomes the key link in the rice cropping operation.Traditional method for preparing soil in rice field is will plough good field piece earlier to carry out smooth, be divided into uniform rectangular grid field again, one lattice Tian Weiyi furrow, and make and reach smooth in the furrow, also sublateral canal will be set at last, this kind method is because operation is numerous and diverse, and labor intensive is many, land utilization rate is on the low side, does not especially fit into the large tracts of land plot of complicated topographical conditions.
The objective of the invention is to provides a cover to be suitable for the time saving and energy saving of large tracts of land plot, the method for preparing soil in rice field that land utilization rate is high at the deficiency of above traditional method of soil preparation.
Even rectangular grid field formula is in the past changed in the setting on the method for soil preparation furrow of the present invention ridge, and the contour setting in strict accordance with the field piece is generally irregular curve, and its step is as follows:
1, plow: routine work;
2, dig rake: select suitable plane rake facility and operating type at landform, eliminate extreme de-luxe compartment and low hole, make ground tentatively smooth substantially;
3, survey line: find out the discrepancy in elevation with the spirit level of mapping usefulness and be not more than the rule contour of 5cm and give mark, the value of the discrepancy in elevation is relevant with the smooth situation in ground with the gradient in plot size, and value was big when gradient reached poor flatness more greatly;
4, ridging: become the ridge along the contour ridging;
5, wipe off: machinery flattens in the furrow, reaches the quality requirement of " discrepancy in elevation is only very little, and very little water does not reveal mud ";
If obvious de-luxe compartment and hollow are arranged, can going ahead of the rest, it is flat suitably to push away before plowing; And the discrepancy in elevation between adjacent contour is preferably 3-5cm, and makes region area that adjacent contour surrounds at 500-1000m
2For making whole ground effect even more ideal, can after strickling, carry out the whole ground of water in conjunction with preseeding irrigation, promptly in furrow, discharge water, with the water lining, the people walks further smooth furrow face with water.
Adopt this kind method of soil preparation, have following significant advantage:
1., the mechanical work level is few.Compare with conventional method, lacked and beaten the straight ridge and plough sublateral canal two links, alleviated machinery rolling topsoil;
2., save the labour.Reduced the required amounts of labour such as connecing ridge head, finishing sublateral canal and artificial level land;
3., improve land utilization rate.Because the embanked field enlarged areas has shortened the sub-total length in the ridge in the whole plot, and has not established sublateral canal, and land utilization rate is brought up to about 95% by original 70-80%;
4., reduce cost.Though increased survey contour link, the machine power of unit are input and manpower work all greatly reduce generally.
It below is a specific embodiments of the present invention.
The part plot landform schematic diagram that Fig. 1 intercepts for virtual certain the large tracts of land bar Tanaka after finishing of present embodiment wholely.Rectangle AEFL shown in it by the edge in intercepting plot, AK, BC, DH, EG are contour (ridge).Present embodiment comprises the steps:
1, plow: the conventional means topsoil that loosens;
2, planing: do the machinery planing according to topographic features, in order to eliminate extreme low hole and de-luxe compartment, so that ground is tentatively smooth;
3, survey line: the spirit level with mapping usefulness is found out the contour that the discrepancy in elevation is 3cm, and makes region area that adjacent contour surrounds at 500-1000m
2
4, ridging: adopt with the adaptive clean-up scraper of small tractor to become the ridge along every contour ridging, ridge bottom width 30cm, the high 15-20cm in the ridge for the adjustable soil scrapper of " eight " font and two wing plate subtended angles;
5, wipe off: utilize the clean-up scraper of small tractor traction between the ridge, to wipe off in the furrow, angle between clean-up scraper and the hitch frame can be adjusted according to topographic features, it is smooth to reach the groove that ridging is formed, and make the interior flatness of whole furrow reach the quality requirement of " discrepancy in elevation is only very little, and very little water does not reveal mud ";
6, the whole ground of water: in conjunction with preseeding irrigation, the people walks with water, and with the water lining, the artificial elimination wipeed in the operation clean-up scraper seam and limit, the ridge off and omitted, further smooth consolidation furrow face, and leak sealing is filled a vacancy and is repaiied the kind furrow ridge.
Intercepting part A EFL shown in the present embodiment also can be the part in non-field piece of certain large tracts of land, so that this method of soil preparation further is adapted to the different shape plot except that the bar field, thereby further embody the superiority of this method with respect to the rectangular grid field formula method of soil preparation of routine, and its isocontour distribution not only is confined to the form that simulates in the foregoing description, should be to show as various shape according to actual topographic features.
Method involved in the present invention can also extend in any crop genetics that the plot flatness is had higher requirements of except that the rice field other.
Claims (4)
1, a kind of method for preparing soil in rice field, its flow chart comprises and plows, digs rake, ridges into furrow, scrapes the equality link in the furrow, it is characterized in that described ridging is each bar contour of measuring earlier and identify in the plot, and making the discrepancy in elevation between adjacent contour be not more than 5cm, ridging becomes the ridge on contour then.
2, method of soil preparation as claimed in claim 1 is characterized in that the ridge, ridge of getting is irregular curve.
3, method of soil preparation as claimed in claim 1 or 2 is characterized in that the discrepancy in elevation between described adjacent contour is decided according to digging ground gradient degree behind the rake and smooth situation, is generally 3-5cm, and makes region area that adjacent contour surrounds at 500-1000m
2Be the best.
4, method of soil preparation as claimed in claim 3 is characterized in that the discrepancy in elevation between described adjacent contour is definite value.
