具体实施方式detailed description
以下结合附图对本发明的具体实施方式进行详细说明。应当理解的是，此处所描述的具体实施方式仅用于说明和解释本发明，并不用于限制本发明。Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
在本发明中，在未作相反说明的情况下，使用的方位词如“上、下”通常是以相应的附图的图面为基准定义的。In the present invention, unless otherwise stated, the used orientation words such as "upper and lower" are usually defined based on the drawings of the corresponding drawings.
如图1所示，本发明提供一种沙地人工种植区防风固沙的系统，包括铺设于沙地人工种植区地表的秸秆覆盖层2。通过上述技术方案，在沙地人工种植区地表全面平铺秸秆覆盖层，该系统防风固沙效果优良，通过秸秆的特性，能够提高作物的保存率，促进作物生长，且成本低廉，降低工程成本。As shown in FIG. 1 , the present invention provides a windproof and sand-fixing system for artificially planted sandy areas, including a straw covering layer 2 laid on the surface of artificially planted sandy areas. Through the above-mentioned technical scheme, the straw covering layer is fully laid on the surface of the sandy artificial planting area. The system has an excellent windproof and sand-fixing effect. Through the characteristics of the straw, it can improve the preservation rate of crops and promote crop growth, and the cost is low, reducing the project cost.
作为本发明的另外一种实施方式，也可以先在人工沙地种植区地表铺设一层筛网1，然后再在筛网1上全面平铺秸秆覆盖层。具体地，在人工种植区地表铺设筛网1的孔径大于地表种植植被的杆径，即，筛网1不会影响种植植被的生长，且能够阻挡风刮起地表的沙土，筛网1可以为尼龙网。As another embodiment of the present invention, it is also possible to lay a layer of screen 1 on the surface of the artificial sand planting area first, and then spread the straw covering layer on the screen 1 completely. Specifically, the aperture of the sieve 1 laid on the surface of the artificial planting area is larger than the rod diameter of the planted vegetation on the ground, that is, the sieve 1 will not affect the growth of the planted vegetation, and can block the wind from blowing up the sand on the surface. The sieve 1 can be Nylon mesh.
其中，在本发明中，衡量防风固沙效果的参数主要为地面的起沙风速，且地面的起沙风速越大，秸秆覆盖层的防风固沙效果越好。沙地人工种植区地表的起风沙速随秸秆覆盖层2厚度的增加而增加，即，秸秆覆盖层2越厚，其防风固沙效果越好，因此，在本发明的实施方式中，秸秆覆盖层2至少包括相互交错地重叠的两层。秸秆覆盖层2能够增加地面粗糙度，使地面的起风沙速增大，防风效果好。此外，地表的秸秆覆盖层2能够减弱土壤水分的蒸发，增加土壤的保水性，对沙地种植区地表的节水也有一定帮助，且秸秆的分解也可以增加土壤营养成分，改善沙地的理化性质，促进土壤有机质转化为植物可利用的营养，在一定程度上增加土壤的有机质，增加土壤肥力。Wherein, in the present invention, the parameter to measure the windproof and sand-fixing effect is mainly the ground sand-emission wind speed, and the greater the ground sand-emission wind speed, the better the windbreak and sand-fixation effect of the straw covering layer. The speed of wind and sand on the surface of the artificial planting area of sandy land increases with the increase of the thickness of the straw covering layer 2, that is, the thicker the straw covering layer 2, the better the windproof and sand-fixing effect. Therefore, in the embodiment of the present invention, the straw covering layer 2 includes at least two overlapping layers. The straw covering layer 2 can increase the roughness of the ground, increase the speed of wind and sand on the ground, and has a good windproof effect. In addition, the straw cover layer 2 on the surface can reduce the evaporation of soil moisture and increase the water retention capacity of the soil, which is also helpful to the surface water conservation in sandy land planting areas, and the decomposition of straw can also increase soil nutrients and improve the physical and chemical properties of sandy land. It can promote the transformation of soil organic matter into nutrients available to plants, increase soil organic matter to a certain extent, and increase soil fertility.
其中，在本发明中，秸秆覆盖层2中每一层的秸秆与秸秆之间进行交叉搭接，以增加稳定性，抵抗风力的破坏作用，增加防护效果。并且通过这种布置方式，更利于秸秆覆盖层的施工。相关人员可以不需对秸秆进行排序和整理，只需将秸秆分摊开来即可，这充分利用了秸秆的特性，不仅防风效果极佳，而且施工操作方便。其中需要说明的是，图1仅是示意性的表达本发明的技术方案，并不用于限制秸秆的具体结构以及相互之间的布置方式。实际上，秸秆上具有众多毛刺或分支，因此在相互搭接的过程中可以相互稳定的实现连接，保证防风效果。另外，通过这些小的分支还可以与筛网1的筛孔进行插接结合，使二者有机的结合为一体，进一步提升防风效果。Wherein, in the present invention, the straws of each layer in the straw covering layer 2 are overlapped with each other to increase stability, resist wind damage, and increase the protective effect. And through this arrangement, it is more conducive to the construction of the straw covering layer. Relevant personnel do not need to sort and organize the straw, but only need to spread the straw, which makes full use of the characteristics of the straw, not only has excellent windproof effect, but also is convenient for construction and operation. It should be noted that Fig. 1 is only a schematic representation of the technical solution of the present invention, and is not intended to limit the specific structure of the straws and their mutual arrangement. In fact, there are many burrs or branches on the straw, so they can be stably connected to each other in the process of overlapping each other to ensure the windproof effect. In addition, these small branches can also be plugged and combined with the screen holes of the screen 1, so that the two can be organically combined to further improve the windproof effect.
其中，在本发明中，秸秆覆盖层2中的秸秆为芦苇秸秆、麦草秸秆、稻草秸秆中的至少一者，用到的秸秆均为就地取材，成本低廉，约为200元/亩，与铺设沙障相比，大大降低了成本而且操作简便，适合大范围实施。Among them, in the present invention, the straw in the straw covering layer 2 is at least one of reed straw, wheat straw, and rice straw, and the straws used are all local materials, and the cost is low, about 200 yuan/mu. Compared with laying sand barriers, the cost is greatly reduced and the operation is simple and suitable for large-scale implementation.
其中，在本发明中，秸秆选择一年生秸秆，杆径较粗、杆长较长的秸秆进行交叉搭接，其防风效果大大增加，且表面的秸秆覆盖层能够减少沙地日光直射，降低地表温度，保护作物幼苗免于日灼危害，提高作物的保存率。Among them, in the present invention, the straw is selected as annual straw, and the straw with thicker diameter and longer length is cross-lapped, and its windproof effect is greatly increased, and the straw covering layer on the surface can reduce direct sunlight on the sandy land and reduce the surface temperature. , protect crop seedlings from sunburn hazards, and improve the preservation rate of crops.
作为本发明的另一种实施方式，为了提高结构的稳定性，避免浪费，更大程度地利用秸秆，当选用，麦草秸秆、稻草秸秆等杆径较细的秸秆时，可以3-5根秸秆通过绳索进行捆绑，然后再进行交叉搭接。As another embodiment of the present invention, in order to improve the stability of the structure, avoid waste, and utilize straws to a greater extent, when straws with smaller diameters such as wheat straw and rice straw are selected, 3-5 straws can be used. The tying is done with ropes and then cross-bonded.
具体地，秸秆覆盖层2的铺设厚度为5-7cm，既不影响种植植被的生长，又起到防风固沙的作用，也不会影响土壤呼吸和雨水下渗。当未铺设秸秆覆盖层2时，地面的起风沙速大约为5m/s，当秸秆覆盖层的铺设厚度由5cm增大到7cm时，地面的起沙风速由5m/s增大至9m/s，继续增加秸秆覆盖层的铺设厚度，地面的起风沙速增加的不大，因此将秸秆覆盖层2的铺设厚度可以为5-7cm。Specifically, the thickness of the straw covering layer 2 is 5-7 cm, which will neither affect the growth of planted vegetation, but also play the role of windbreak and sand fixation, and will not affect soil respiration and rainwater infiltration. When the straw covering layer 2 is not laid, the wind and sand velocity on the ground is about 5m/s, and when the laying thickness of the straw covering layer increases from 5cm to 7cm, the sand velocity on the ground increases from 5m/s to 9m/s , continue to increase the laying thickness of the straw covering layer, and the speed of wind and sand on the ground does not increase much, so the laying thickness of the straw covering layer 2 can be 5-7cm.
根据本发明的另一个目的，提供一种沙地人工种植区防风固沙的方法，包括以下步骤：According to another object of the present invention, there is provided a method for windproof and sand-fixing in artificially planted areas in sandy land, comprising the following steps:
1)准备工作：收集秸秆，可以为芦苇秸秆、麦草秸秆、稻草秸秆中的一者或多者。测试人工种植区地表的起沙风速并记录，可以与铺设秸秆覆盖层2之后的起风沙速进行对比，以用于衡量防风固沙效果。铺设秸秆覆盖层2之前需要将沙地人工种植区的沙地进行整平、播种并加以灌溉；1) Preparatory work: collecting straw, which can be one or more of reed straw, wheat straw and rice straw. The sand-emission wind speed on the surface of the artificial planting area is tested and recorded, which can be compared with the sand-emission speed after the straw covering layer 2 is laid to measure the wind-proof and sand-fixing effect. Before laying the straw covering layer 2, the sandy land in the sandy land artificial planting area needs to be leveled, sown and irrigated;
2)平铺：在人工种植区地表上全面平铺秸秆覆盖层2，或者先在沙地人工种植区地表覆盖一层筛网1以阻挡风刮起地表的沙土，然后在筛网1上铺设秸秆覆盖层2，且秸秆覆盖层2至少包括相互交错地重叠的两层，防风效果大大增加；2) Tiling: spread the straw covering layer 2 on the surface of the artificial planting area, or first cover a layer of screen 1 on the surface of the artificial planting area in sandy land to prevent the wind from blowing up the sand on the surface, and then lay the straw on the screen 1. The straw covering layer 2, and the straw covering layer 2 includes at least two overlapping layers interlaced with each other, and the windproof effect is greatly increased;
3)测试：测试铺设秸秆覆盖层后地表的起沙风速并记录，与铺设覆盖层2之前的起沙风速进行对比。3) Test: Test and record the sand-emission wind speed on the surface after the straw covering layer is laid, and compare it with the sand-emission wind speed before laying the covering layer 2.
其中，在本发明中，秸秆覆盖层2中每一层的秸秆与秸秆之间进行交叉搭接，增加其稳定性，抵抗风力破坏，彼此相互交叉搭接的秸秆之间会留有一定的缝隙，不会影响土壤的呼吸和雨水下渗，且当种植植被长出后，又可以进一步固定秸秆，达到种植植被与秸秆的互利互惠，促进种植植被的生长。具体地，所用秸秆为整株秸秆，不进行裁截粉碎，以增加结构的稳定性，抵抗风力破坏，增加防护效果。Among them, in the present invention, the straws of each layer in the straw covering layer 2 are cross-lapped with each other to increase its stability and resist wind damage, and there will be a certain gap between the cross-lapped straws. , will not affect the respiration of the soil and the infiltration of rainwater, and when the planting vegetation grows, the straw can be further fixed, so as to achieve mutual benefit between the planting vegetation and the straw, and promote the growth of the planting vegetation. Specifically, the straw used is the whole plant straw, which is not cut and crushed, so as to increase the stability of the structure, resist wind damage, and increase the protective effect.
在本发明中，采用直接铺撒的方式铺设秸秆，可以通过人工或机械的方式铺洒，易操作、省时省力且防风固沙效果优良。具体地，秸秆的用量一般为200kg/亩，地面覆盖率能达到80％，且所用秸秆可以为芦苇秸秆、麦草秸秆、稻草秸秆中的一者或多者，均为就地取材，因此该方法的成本低，试验防风固沙效果好。与铺设直立式沙障、平铺式沙障和固沙剂相比，施工过程较为简单，且造价低廉，可以进行大范围覆盖。In the present invention, the straw is laid directly by spreading, which can be spread manually or mechanically, which is easy to operate, saves time and effort, and has excellent windproof and sand-fixing effects. Specifically, the amount of straw is generally 200kg/mu, and the ground coverage rate can reach 80%, and the straw used can be one or more of reed straw, wheat straw, and rice straw, all of which are obtained locally, so the method The cost is low, and the test windproof and sand-fixing effect is good. Compared with laying vertical sand barriers, flat sand barriers and sand-fixing agents, the construction process is relatively simple, and the cost is low, and it can cover a large area.
