The present invention relates to a light-shielding sheet for agriculture.In general, it is difficult to cultivate soft vegetables such as lotus grass and Chinese cabbage during the high temperature and rainy season of summer. This is because soft vegetables are not only sensitive to high temperatures, but also to rapid environmental changes caused by heavy rainfall, and high humidity can encourage root rot, pests, and virus outbreaks. As described above, soft vegetables are extremely susceptible to long-term high temperatures and heavy rain, making it difficult to cultivate them in the summer. Despite this current situation, several methods have been proposed for cultivating soft vegetables in the summer. All of these methods use films to prevent rainwater from falling onto broken cultivation soil, thereby avoiding various problems caused by high humidity. There are roughly two types of methods in practical use. One is (A) a method using a pipe house used in greenhouse horticulture. By covering the top surface of the pipe house with various types of agricultural films, we avoid the effects of rainwater, and at the same time, use cheesecloth and other light-shielding materials to control strong light in the summer, avoid high temperatures inside the facility, and stabilize growth. It's a method. In some cold regions, cultivation is possible even without using any light-shielding materials due to the relatively low temperature. Cheesecloth, cloth, etc. are used as the covering material. There are several ways to stretch the film, such as above or below the film, or inside the film in a curtain style. This method has the advantage of allowing a large ridge width, but has the disadvantage of requiring high material costs and being difficult to move to other locations. One particular drawback is that it causes continuous cropping failure, which is a fatal problem for vegetables, and is a problem for many farmers.
As a method that overcomes the drawbacks of method (A) above and allows cultivation to be moved from place to place at a low cost, (B) tunnel cultivation method using a tunnel with a width of 2 m or less is used. In this case, as in the method (A) above, there is a method of simultaneously using an agricultural film and a light-shielding material to avoid the influence of rainwater and adjust the intensity of light, as well as a method of using a translucent film. The method uses two different materials, which requires more effort and cost for farmers to cover.
It has the following disadvantages. Unlike method 2, method 2 uses one type of material, so the drawbacks are covered, but because the film does not have hygroscopic properties, problems due to high humidity inside the tunnel, that is, diseases are likely to occur, and the tunnel becomes overgrown. This has the disadvantage that it tends to reduce the commercial value of crops. The problem of high humidity inside the tunnel can also be seen with the above method. This is a phenomenon that occurs because the internal volume of the tunnel method is extremely small compared to method (A), and method (A) has the drawbacks mentioned above compared to method (B), even though the cost is higher. This is a major reason why it is still used. This idea was developed in view of the current situation.
The object of the present invention is to obtain an agricultural light-shielding sheet that can grow soft vegetables and the like in a healthy manner without causing humidity inside the sheet even when used in tunnel cultivation. In order to achieve this object, the present invention has the following configuration. In other words, the present invention is an agricultural shade sheet that has a structure in which a film-like sheet and a nonwoven fabric sheet with a basis weight of 20 to 60 g/ m2 are bonded together.If the sheet of the present invention is used for tunnel cultivation, moisture inside the tunnel can be reduced. is absorbed by the non-woven fabric inside the sheet, preventing the inside from becoming humid, and combined with the light-shielding effect of the non-woven fabric and the rain-preventing effect of the film, it is possible to grow soft vegetables and the like in a healthy manner. The present invention will be explained below with reference to the drawings. FIG. 1 is a cross-sectional view of the agricultural shade sheet of the present invention in the width direction. FIG. 2 is a cross-sectional view in the width direction of another embodiment of the agricultural shade sheet of the present invention. FIG. 3 is a side view showing the agricultural shade sheet of the present invention shown in FIG. 2 being used for tunnel cultivation. As shown in FIGS. 1 and 2, the agricultural light-shielding sheet of the present invention has a structure in which film sheets 1, 1' and nonwoven fabric sheets 2, 2' are integrally joined. In the case of the agricultural light-shielding sheet shown in FIG. 2, the portions 3, 3' made only of nonwoven fabric have a width of 5 to 30 cm. The nonwoven fabric used in this invention is a nonwoven fabric made of long or short fibers such as polypropylene fibers, polyacrylic fibers, or nylon fibers, but since it is desirable to have strong strength for agricultural use, long fiber nonwoven fabric is preferable to short fiber nonwoven fabric. . In particular, spunbond nonwoven fabrics with medium-long fibers are most suitable. The light shielding rate of the nonwoven fabric used in the present invention varies depending on the soft vegetables grown, but is 20% to 90%, preferably 30% to 50%. Therefore, the basis weight of the nonwoven fabric used in the present invention is 20g/m 2 to It is about 60g/m2.
If it is less than 20g/m2, the light blocking effect will be poor, and if it is less than 60g/ m2
Above that, there will be insufficient sunlight. It is desirable to have sufficient air permeability when covering the entire surface, and the air permeability is 50~
500 c.c./cm 2 /Sec (Fragile method) is suitable. Films used in the present invention include polyethylene, polyvinyl acetate, polypropylene, polyvinyl chloride, polyester, and polyamide. Various known methods can be used to join the above-mentioned nonwoven fabric and film together. These include a method of laminating a part or the entire surface of a film and a nonwoven fabric using a thread sewing machine, a high-frequency welder, etc., and a method of laminating a film and a nonwoven fabric using a known lamination method such as dry lamination or extrusion lamination. Also, the method of laminating film and nonwoven fabric is the first
As shown in the figure, it is possible to use a film and non-woven fabric of the same width, or as shown in figure 2, to take advantage of the breathability of the non-woven fabric, the width of the film can be narrowed by 10 to 60 cm, so that the width of the film can be narrowed by 10 to 60 cm. They may be bonded together so that both ends of the width have a portion of only the nonwoven fabric 5 to 30 cm wide. The present invention has the above configuration. When the agricultural shading sheet of this invention is used for tunnel cultivation, the moisture inside the tunnel will be absorbed by the non-woven part inside the sheet, preventing the interior from becoming too humid. It is possible to grow soft vegetables and the like in a healthy manner. One of the major features of this invention is that the nonwoven fabric has hygroscopic properties, which prevents high humidity inside the tunnel, which is a drawback of tunnel cultivation methods, and greatly reduces the various problems caused by high humidity, thereby increasing the commercial value of crops. Moreover, since the non-woven fabric itself is breathable, if it is manufactured so that when bonded together, there is at least 5 cm of non-woven fabric on both ends, the entire surface of the tunnel can be covered with the field-use light-shielding sheet according to the present invention. This makes it possible to significantly reduce the damage caused by viruses and other pests on soft vegetables during the summer. Furthermore, as mentioned above, soft vegetables in the summer are grown in high-temperature climates, so heat shielding properties are an important element required of materials, and the agricultural shade sheet according to the present invention has a light shielding rate of 20 to 90 as a heat shielding material. % nonwoven fabric is used, and since the nonwoven fabric itself is a breathable material, it has excellent heat shielding effects, and has great commercial value as shown by the data on plant height, weight, and bolting rate in Table 1 below. Another major feature is that crops can be grown. Next, we will present an example of using the agricultural shade sheet of the present invention for tunnel cultivation. The agricultural shading sheet used in this experiment was an agricultural polyethylene film (thickness: 50 microns), and a polyester long fiber spunbond nonwoven fabric (shading rate: 30 microns) as a nonwoven fabric.
%, air permeability of 320 c.c./cm 2 /sec, and basis weight of 30 g/m 2 ) and laminated to produce an agricultural shade sheet with a width of 180 cm, which has a nonwoven fabric portion at each end of the width of 10 cm. This light-shielding sheet was sown with Horen grass (variety: King of Denmark) in a 100cm wide flat furrow, and then the base part was 15mm thick as shown in Figure 3.
I set it up with a cm opening and performed tunnel cultivation. For comparison, tunnel coating was not applied (Comparative Example 1), black cheesecloth was covered with agricultural polyethylene film instead of the light-shielding sheet of the present invention (Comparative Example 2), and white cheesecloth was used as the covering material. Comparative cultivation was carried out using agricultural polyethylene film (Comparative Example 3) and aluminum kneaded opaque polyethylene film (Comparative Example 4) under the same conditions. The seeds were sown on July 27th, and the observation results of the growth status as of August 25th, about one month later, are shown in Table 1.

[Table] As can be inferred from Table 2, the crops used in the present invention have a high dry matter percentage and long leaf blades. This is because the hygroscopic and heat-insulating properties of non-woven fabric make the environment inside the tunnel more like an open field for crops.
This proves that it is extremely advantageous in increasing the commercial value of crops.
