Example 1.
The embodiment provides a method for cultivating a grass field in a reverse desert, which is applied to autumn every year, and a flow chart of the method is shown in fig. 1, and specifically comprises the following steps:
s1, determining a boundary line between grasslands and deserts as a datum line;
s2, uniformly arranging a plurality of grooves parallel to the datum line on one side of the desert;
s3, uniformly spreading quicklime to the bottom of the groove;
s4, cleaning agricultural residues and cattle and sheep manure on the grasslands, filling the residues into the grooves, and compacting;
s5, covering the nylon net on agricultural residues and cattle and sheep manure in the groove, and fixing the nylon net;
s6, backfilling the fine sand into the groove to level the position of the groove.
The schematic diagram of the hierarchical structure in the trench obtained through the steps is shown in fig. 2. In most cases, the boundary line between the desert and the grassland is a curve, the planting method is suitable for multi-ring grassland planting, two rings are taken as an example, as shown in fig. 3, the boundary line between the desert and the grassland can be used for marking a first ring line by using quicklime on one side of the desert, the first ring line is 5m away from the reference line, a second ring line is further marked on one side of the desert far from the reference line, the second ring line is 5m away from the first ring line, grooves are respectively dug towards two sides by taking the first ring line and the second ring line as the centers, and the total width of the grooves is 2m and the depth is about 0.4 m; two annular grooves were obtained as new grass cultivation grooves. Quick lime with the thickness of about 2mm is scattered at the bottom of the groove, hay on the grasslands is collected by a mower and a rake, and the hay and the manure of the cattle and sheep with the sticky tape are filled into the new grassland cultivation annular groove. The upper part of the hay is approximately flush with the groove, a nylon net is covered on the hay in the groove, the hay is fixed by a crotch with the length of 0.5m at least at one end, and fine sand is backfilled by using a manual or earth covering machine.
The method provided by the embodiment is applied to the junction of the desert and the grassland, most of materials can be obtained locally, and the method is simple and convenient. The agricultural residues are buried in the shallow surface layer of the desert, so that the moisture provided by autumn precipitation and winter precipitation is preserved, and the water storage capacity of the surface layer of the desert is improved; under the action of the nylon net, even if fine sand covered on the surface of agricultural residues is blown away, the buried hay is not easy to blow away, and as the agricultural residues are not crushed, the hay which is interwoven together is more favorable for being fixed in a ditch, and the moisture is easier to be preserved; grass seeds or perennial root grasses attached to the embedded agricultural residues can regenerate or germinate in spring of the next year, and the rest of the partially degraded hay and cattle and sheep manure provide partial nutrition for the growth of the new grass, so that the new grass grown under the condition of mixing the hay and fine sand has stronger adhesive force at the root compared with the new grass planted by a single common method, and is not easy to be blown away by the root. Under the condition of periodic maintenance, new grasses are gradually grown and connected into a piece, so that the grasses can gradually expand towards the desert, and the effect of reverse-eating the desert by the grasses is generated.
The cleaned grasslands are favorable for sprouting new grasses in the next year, and are convenient for cattle and sheep to remove interference of hay and eat green grasses; and the grasslands after the hay is cleaned reduce the raw materials of grassland biological flocculation pits of Daur yellow rats and the like, do not have the shielding of redundant hay, and are more beneficial to the predation of small animals by natural enemies on the ground and sky of the small animals.
Example 2.
This example is a further illustration of example 1, where the trench has a depth of 0.3m to 0.5m.
The size of the groove is not strictly required, the depth of the groove is flexibly set according to the amount of the hay, and the embodiment limits the depth of the groove to 0.3m-0.5m, so that the defect that the water storage capacity of the hay is insufficient due to the too shallow depth is avoided, and the novel grass is not easy to root in the desert due to the too deep depth.
Example 3.
This example is a further illustration of example 1, where the trench has a width of 1m-4m.
In the embodiment, the width of the groove is limited to be 1m-4m, preferably 2m, so that the problem that the strength is reduced due to the too large width of the nylon net is avoided, and the hay is not convenient to wrap and fix.
Example 4.
This example is a further illustration of example 1, where the grooves have a pitch of 3m to 10m.
Example 5.
This example is a further illustration of example 1, wherein the quicklime has a thickness of 2mm to 5mm.
The quicklime has the function of forming a thin water-retaining layer by fusing quicklime and fine sand under the action of water vapor or snow water, so that the quicklime has the function of properly retaining water and does not prevent new grass from taking root under the desert. The present embodiment therefore limits the quicklime layer thickness to 2mm-5mm, preferably 2mm, avoiding that too much thickness would affect downward rooting of new grass.
Example 6.
This example is a further illustration of example 1, where the agricultural residues include grass seed, hay, and mulch-leaf.
The agricultural residues in the embodiment are local materials, and the agricultural residues such as grass seeds, residual hay, dead branches and dahurian leaves and the like on the cleaned grasslands and the cattle and sheep manure are used as raw materials to serve as necessary raw materials for the growth of new grass, so that the method is simple and convenient.
Example 7.
This example is a further illustration of example 1, wherein the nylon mesh is secured as described in step S5, specifically by inserting the raw sand downwardly through the nylon mesh using a crotch down.
The first choice for fixing the nylon net in the embodiment is the prepared crotch, and the nylon net is fixed by the crotch, so that the environment is not destroyed, and the nylon net can be naturally degraded under the action of one or two years to serve as a fertilizer of grasslands.
Example 8.
This example is a further illustration of example 7, wherein the crotch has at least one end having a crotch length greater than the depth of the groove.
Example 9.
This embodiment is a further illustration of any one of embodiments 1-8, wherein when the reference line is a straight line, the step S2 further includes: and a plurality of grooves are uniformly arranged in the direction perpendicular to the grooves parallel to the reference line.
When the boundary between the grassland and the desert is approximately straight, a plurality of annular grooves are formed as in embodiment 1, then a plurality of grooves are uniformly formed in the direction perpendicular to the annular grooves, as shown in fig. 4, a plurality of cross grids are manufactured on the side of the desert near the boundary between the desert and the grassland, and the steps of quicklime, hay filling, nylon net covering and fine sand backfilling are performed in the cross grids grooves in the same manner as in embodiment 1. According to the method, through the cross structure, new grasses can be connected into one piece more quickly and effectively, so that grasslands gradually expand quickly towards the desert direction, and the effect of reverse desert of the grasslands is achieved.
