Description

  The present invention relates to an agricultural house provided on an inclined land where crops are cultivated.

  In fruit tree cultivation, an agricultural plastic house is laid on a gentle slope and cultivated in this agricultural plastic house has already been made in many areas. In China, Nikko greenhouses have been used for a long time. This sunlight greenhouse is made of a material that has heat storage properties, and forms walls on both the north and east and west sides, and covers the south side with a translucent film, so that the indoor temperature can be utilized using the heat storage performance of the walls. (See, for example, Non-Patent Documents 1 and 2). On the other hand, in Japan, a new greenhouse laying technique utilizing sloping land has been announced (for example, see Non-Patent Document 3).

Tomoharu Yamaguchi, Takeshi Kuroyanagi, Chen Seunun, “Study on the Formation of Thermal Environment in Nikko Greenhouse (Part 1)”, Agricultural Facility, Agricultural Facility Society, June 2003, Vol. 34, No. 1, P.31- 37 Satoshi Yamaguchi, Wei Mashu, Jin Jin, “Current Status and Prospects of Engineering Technology in China's Facility Horticulture”, Agricultural Facilities, Agricultural Facility Society, June 2001, Vol. 32, No. 1, P.23-32 Yoshiharu Iriguchi and three others, "Development of multi-sun and wind-resistant house and sleek cultivation of gerbera utilizing sloping land in mountainous area", Nagasaki Prefectural Agricultural and Forestry Experiment Station Research Report (Agriculture), No. 22, P.23-33 ,

  However, agricultural plastic houses laid on gentle slopes have already been produced in greenhouse mandarin oranges, and it is difficult to seek higher profits as they are. Furthermore, when an agricultural plastic house is used, a heating facility such as a boiler is necessary for measures against low temperatures in winter, and thus the cost required for this heating facility cannot be ignored. In addition, since the opening and closing of the covering material, which involves a lot of labor and danger, is indispensable for countermeasures against high temperatures in the summer, the work load is large. Furthermore, problems such as collapse of the house due to strong winds, increased burden due to work on slopes, and aging of the gardener can be considered. Therefore, the number of abandoned orchards is increasing in orchards using agricultural plastic houses.

  On the other hand, in horticultural cultivation of vegetables and the like, agricultural house cultivation brings high profits, and therefore, utilization of agricultural houses has been attempted even in hilly and mountainous areas. However, even a house laid in a mountainous area is exactly the same in structure as a house laid on flat ground. Therefore, due to gusts peculiar to hilly and mountainous areas and severe cold in the winter season, the competition for cultivation under severe weather conditions compared to flat farming has not been realized, and the spread of agricultural houses has not progressed.

  Furthermore, although Nikko greenhouses are widely used in China, there are no examples of laying on slopes, and there are no examples of providing a safe work passage above the greenhouse. Also, in the greenhouse laying technology using slopes that have already been announced, the structure of the greenhouse is disclosed, but no device for improving workability is found.

  Therefore, the present invention has been made paying attention to the above problems, and provides an agricultural house capable of cultivating high value-added crops while reducing costs while reducing work burdens in hilly and mountainous areas. The purpose is to do.

  In order to achieve the above object, in the agricultural house of the present invention, the agricultural house of the present invention is laid on a step land having an installation surface, a wall surface rising from the installation surface, and an upper work road that continues in a horizontal direction from the upper end of the wall surface. An upper side wall extending in a vertical direction from an upper end portion of the wall surface, and a roof portion standing on the installation surface and connected to the upper end portion of the upper side wall, wherein the wall surface is a part of the side wall. It is characterized by doing.

Therefore, in the agricultural house according to the present invention, the wall surface of the stepped land having the upper work path is a part of the side wall, is erected on the installation surface, and extends in the vertical direction from the upper end portion of the wall surface. It has a side wall.
That is, by making the side surface of the stepped land part of the side wall of the agricultural house, it is possible to save the house constituent materials such as the skeleton pipe and the covering material corresponding to the side wall. In addition, it is possible to place an upper work road at the top of the house by standing on the installation surface of the stepped land with the upper work road. Since necessary work such as attachment and detachment of materials can be performed, the work load is reduced. Further, by using the upper work road, it is possible to easily secure a place for installing equipment such as a covering material hoisting device on the upper part of the house. Thereby, the burden concerning an agricultural house can be reduced and it can prevent that a failure | damage arises.
As a result, high value-added crops can be cultivated in a mountainous area while reducing the work load and reducing costs.

Here, the height H1 of the temperature adjusting wall surface 3 is set to about 2 to 3 m from the house installation surface 2. The temperature adjusting wall surface 3 is inclined upward with respect to the vertical direction. Further, here, the entire temperature adjusting wall surface 3 is covered with a heat storage material 3a having a high heat capacity. The heat storage material 3 a is, for example, a concrete block, brick, natural stone, or the like, and also has a function as a retaining wall that prevents collapse by being stacked on the surface of the temperature adjusting wall surface 3. The method of stacking these heat storage materials 3a can be selected in accordance with the shape, inclination angle, etc. of the wall surface 3 for temperature adjustment, such as flat stacking or cloth stacking. Further, the concrete may not be in the form of a block but may cover the entire surface of the temperature adjusting wall surface 3 integrally.

  The upper work path 4 is a work path that continues in the horizontal direction from the upper end portion 3 b of the temperature adjusting wall surface 3. Similar to the house installation surface 2, the upper work path 4 extends in a strip shape along the contour line. And the width W2 of this upper stage work path 4 needs to have the length which a person or an agricultural machine can pass, and is about 0.5-3 m according to a general work path here. .

  The inclined field 5 is a field in which the field surface 5a for growing crops such as fruit trees is inclined from the upper work road 4 to the upper part of the inclined land. Here, a plurality of in-field work paths 5b,... Extending in a strip shape in the field surface 5a are arranged at regular intervals in the height direction. The field surface 5a is demarcated along the contour lines by these field work paths 5b,. Each field work road 5b has such a width that a work machine such as a speed sprayer SS or an aerial work vehicle KS can travel.

  FIG. 3 is an external perspective view showing a part of the agricultural house of Example 1. FIG. FIG. 4 is a cross-sectional explanatory view in which a part of the agricultural house of Example 1 is broken.

  The agricultural house 10 is erected on the house installation surface 2 so as to integrally cover the house installation surface 2 and the temperature adjustment wall surface 3, and the temperature adjustment wall surface 3 is a part of the side wall. The agricultural house 10 includes an upper side wall 11, a roof portion 12, and a pair of wife side walls 13.

  The upper side wall 11 is a side wall extending in the vertical direction from the upper end portion 3 b of the temperature adjusting wall surface 3, and projects upward from the upper work path 4. The height H2 of the upper side wall 11 is set to a height that allows work on the roof portion 12 from the upper work path 4 through the upper side wall 11, and here, about 0.5 from the upper work path 4 is set. About 1.5m. The “operation on the roof portion 12” includes an attaching / detaching operation and a re-installation operation of the covering material 10a described later, irrigation / pesticidal operation from the roof portion 12, and the like. The upper side wall 11 is provided with an openable and closable ventilation window 11 a for ventilating the agricultural house 10. Moreover, this upper side wall 11 is comprised by the coating | covering material 10a and the framework pipe 10b which are mentioned later.

  The roof portion 12 integrally covers the house installation surface 2 and the temperature adjusting wall surface 3, one end is connected to the upper end portion 11 b of the upper side wall 11, and the other end is fixed to the house installation surface 2. It has an arcuate arch shape. Moreover, this roof part 12 is comprised from the framework pipe 10b used as the frame | skeleton of the agricultural house 10, and the coating | covering material 10a fixed to this framework pipe 10b so that attachment or detachment was possible. The covering material 10a is a synthetic resin film having translucency composed of an agricultural polyolefin film or a fluororesin film. The covering material 10a may be a sheet in which a light-shielding curtain or a futon-like heat insulating covering material is detachably superimposed on a synthetic resin film having translucency.

  The said wife side wall 13 is a side wall located in the wife surface of the agricultural house 10, and the entrance / exit 13a is provided. The wife side wall 13 is constituted by the covering material 10a and the framed pipe 10b.

Next, the operation will be described.
First, the “technical problem of an agricultural house in a hilly and mountainous area” according to the present invention will be described, and then the effects on the agricultural slope 1 of Example 1 will be referred to as “a crop added value improving effect”, “an improvement in workability”. The operation will be divided into “operation” and “cost control operation”.

[Technical issues of agricultural houses in hilly and mountainous areas]
The mountainous region of western Japan with a well-drained soil with a warm climate is prosperous for citrus cultivation and forms the main production area. In this region, with the increase in fruit demand since the 1960s, Wenzhou mandarin orchards have been actively opened even on steep slopes. Today, however, many farmers are abandoned without a successor due to the declining price of mandarin oranges. In addition, there is a demand for lighter work on slopes even in ongoing parks. For this reason, there is a demand for the development of new cultivation facilities that take advantage of the characteristics of sloping land in order to revitalize citrus production areas and effectively use sloping land in hilly and mountainous areas.

  However, in the conventional cultivation using the agricultural house, the cost required for heating in the winter season becomes large, which may put pressure on management. In addition, farmhouses laid on sloping grounds such as sloping orchards, in addition to increasing heating costs, are not structurally different from houses laid on flat ground, so there are gusts and winters peculiar to mountainous areas. As a result of severe cold, damage is more frequent than in flatland agriculture. In addition, work on slopes is more burdensome than farming on flat land, and using an agricultural house can further increase the burden. That is, in sloped areas in hilly and mountainous areas, even if high value-added crops are cultivated using agricultural houses, there are problems such as increased costs and severe weather conditions, making it difficult to spread agricultural houses.

[Crop added value enhancement]
The agricultural house 10 of the first embodiment includes a house installation surface 2, a temperature adjusting wall surface 3 rising from the house installation surface 2, and a step having an upper work path 4 continuous from the upper end 3 b of the temperature adjusting wall surface 3. It is laid on the agricultural slope 1 which is the ground.

  Therefore, since it is possible to cultivate crops using the agricultural house 10 laid using the agricultural slope 1 which is a stepped area even in the hilly and mountainous area, it is possible to grow the crop all year round in the hilly and mountainous area. . As a result, it is possible to ship crops when the number of cultivated crops is small in the market, or to ship crops of a certain quality, and it is possible to produce crops with higher added value than crops by outdoor cultivation.

[Workability improvement effect]
A slope 1 for agriculture, which is a level difference where the agricultural house 10 of Example 1 is laid, includes a house installation surface 2, a temperature adjustment wall 3 rising from the house installation surface 2, and an upper end 3 b of the temperature adjustment wall 3. Has a continuous upper work path 4.

  Thereby, the operation | work to the roof part 12 of the agricultural house 10 or the house installation surface 2 in the agricultural house 10 can be performed from the upper stage work path 4, and work efficiency can be suppressed and workability | operativity can be improved. Here, the work on the roof portion 12 and the house installation surface 2 includes attaching and detaching work and covering work of the covering material 10a as shown in FIG. 5 (a), and irrigation and pesticide spraying work as shown in FIG. 5 (b). It is.

  Further, as shown in FIG. 5 (a), when attaching / detaching the covering material 10a, the operation can be performed more easily by using a covering material hoisting device (not shown). That is, the covering material 10a fixed to the frame pipe 10b may be wound from the upper work path 4 using the covering material hoisting device. In addition, since the agricultural slope 1 has the upper work path 4, the covering material hoisting device can be installed using the upper work path 4. Thereby, it is not necessary to install the covering material hoisting device on the agricultural house 10, the load applied to the agricultural house 10 can be reduced, and the agricultural house 10 can be prevented from being damaged.

  Furthermore, in the agricultural house 10 of the first embodiment, the height H2 of the upper side wall 11 is set to a height that allows work on the roof portion 12 from the upper work path 4 through the upper side wall 11. For this reason, the worker S1 can work smoothly and can prevent the upper side wall 11 from falling from the upper work path 4. Thereby, it becomes possible to perform work safely.

And the house installation surface 2 of Example 1 is provided in the inclined ground, and while making the strip | belt shape extended along a contour line, the upper stage work path 4 has comprised the strip | belt shape extended along a contour line. Therefore, the agricultural house 10 has a shape along the contour line. In addition, if the width W2 of the upper work path 4 is set to a length that allows the work vehicle S2 such as a speed sprayer to travel, for example, after the covering material 10a is removed, as shown in FIG. The operation from the upper work road 4 can be performed from a vehicle such as the work vehicle S2 traveling on the upper work road 4 so that irrigation / pesticidal spraying work can be performed while traveling on the upper work road 4 using the car S2. Thus, work efficiency can be improved and workability can be further improved.
In particular, by using the boom B along the shape of the roof portion 12, it becomes possible to perform irrigation directly from the work vehicle S2 traveling on the upper work road 4. Therefore, the work load can be further reduced.

  And in the agricultural sloped land structure 1 of Example 1, the house installation surface 2 is formed in the part which became slightly high from the main road 1a in which a vehicle etc. can pass. Thereby, the operation | work with respect to the inside of the agricultural house 5 can be performed from the vehicle which drive | works this trunk road 1a, and the improvement of workability | operativity can be aimed at.

  Further, as shown in FIG. 6, if a water storage tank T for irrigation is installed on the upper work path 4, natural irrigation using the height difference between the house installation surface 2 and the upper work path 4 may be performed. it can. In this case, since it is natural irrigation, the burden of irrigation work can be greatly reduced, and if the irrigation pipe P is used, the effect increases. Furthermore, if the water in the water storage tank T is collected from the rain of the sloped field 5 located above the upper work path 4, labor can be further saved.

In the agricultural house 10 of the first embodiment, the upper side wall 11 is provided with a ventilation window 11a. Therefore, when the temperature and humidity in the agricultural house 10 fluctuate, the ventilation window 11a can be opened and closed to easily ventilate the house, and the environmental condition in the agricultural house 10 can be easily adjusted. Can be done.
In addition, as shown in FIG. 7, the ventilation in a house can be performed more efficiently by providing the window part 12a which can be opened and closed in the part along the upper end part 11b of the upper side wall 11 among the roof parts 12. As shown in FIG. It is possible to improve the heat countermeasure efficiency.

[Cost control action]
In the agricultural slope 1 of the first embodiment, the temperature adjusting wall surface 3 is used as a part of the side wall of the agricultural house 10, so that the material such as the covering material 10 a and the frame pipe 10 b corresponding to the side wall is saved. Cost reduction.
That is, for example, consider the case where the dimensions of a general agricultural house N and the agricultural house 10 of Example 1 are as shown in FIG. At this time, in a general agricultural house N, the cross-sectional length covered with the covering material 10a is 12.2 m (= 2.5 + 3.6 + 3.6 + 2.5). On the other hand, in the agricultural house 10 of Example 1, the cross-sectional length covered with the covering material 10a is 9.8 m (= 8.3 + 1.5). Therefore, when the general agricultural house N is “1”, the ratio of the cross-sectional length is about “0.8” in the agricultural house 10 of the first embodiment, and the covering material 10a is applied even if the cultivation area is the same. It can be seen that it can be reduced by about 20%.

  Further, the temperature adjusting wall surface 3 itself is formed when the house installation surface 2 extending in a strip shape along the contour line is formed. Thus, by actively using the wall 3 for temperature adjustment formed as a result of the creation of the house installation surface 2 as a heat storage body for the agricultural house 10, these creation costs can be reduced to the land maintenance project on the slope. It will be borne by both the construction business of the agricultural house 10, and it becomes possible to carry out slope land creation at low cost.

Moreover, in the agricultural house 10 of Example 1, the wall surface 3 for temperature control is the height which has heat storage property. Therefore, the heat from sunlight is stored in the temperature adjusting wall surface 3, and the stored heat from the temperature adjusting wall surface 3 is released at night or the like, so that the temperature adjusting wall surface 3 is stored in the agricultural house 10 in the low temperature period. It can be used to maintain temperature. That is, by using a part of the side wall of the agricultural house 10 as the temperature adjustment wall surface 3, the temperature adjustment wall surface 3 can be used as a low-temperature heat storage body for low-temperature countermeasures, and heating required for low-temperature countermeasures. Costs such as expenses can be suppressed.
In particular, as shown in FIG. 9, by covering the entire surface of the roof portion 12 with a covering member D made of a light shielding curtain, a futon-like heat insulating covering material, or the like, it is possible to more effectively prevent a temperature drop in the house. .

  And in the agricultural house 10 of this Example 1, the wall surface 3 for temperature control is covered with the thermal storage material 3a which has a high heat capacity. Therefore, the heat capacity that can be accumulated on the temperature adjusting wall surface 3 is increased, and the temperature adjusting wall surface 3 can be provided with a more effective temperature maintaining function.

  Furthermore, the wall surface 3 for temperature adjustment of Example 1 is inclined upward. Therefore, a wide sunlight irradiation area can be secured, the heat capacity capable of storing heat is increased, and the temperature adjusting wall surface 3 can be provided with a more effective temperature maintaining function.

On the other hand, in the high temperature period such as summer, as shown in FIG. 10, the window 12 a provided on the roof 12 is opened and the temperature is adjusted between the window 12 a and the upper end 11 b of the upper side wall 11. By hanging a covering member D made of a light-shielding curtain or a futon-like heat insulating covering material on the front surface of the wall surface 3, the temperature adjusting wall surface 3 is prevented from becoming high temperature and the temperature rise in the agricultural house 10 is suppressed. be able to. In this way, by using the covering member D made of a light-shielding curtain or the like, the temperature adjusting wall surface 3 can be used as a countermeasure against heat in the high temperature period, and the house temperature is good throughout the year while suppressing management costs. An environment can be provided.
In particular, when the light-shielding curtain is hung on the front surface of the wall 3 for temperature adjustment, the front side facing the house is made of a color that easily reflects light such as silver or white, thereby avoiding pests or reflecting light from the south surface. Can expect high quality products.
Furthermore, when the temperature difference between daytime and nighttime is large such as early spring or late autumn, the roof portion 12 is covered with the covering member D as shown in FIG. 9 at night, and the covering member D is used for temperature adjustment as shown in FIG. By hanging on the front surface of the wall surface 3, it is possible to easily achieve a nighttime heat retention effect and a daytime temperature rise prevention effect.
In addition, workability can be improved by installing the covering member D from the upper work path 4. In addition, if the support means for the covering member D is provided on the upper work path 4, it is possible to suppress the burden on the agricultural house 10 and prevent the agricultural house 10 from being damaged.
