Description

The present invention avoids frost and frost damage or plague or tea / fruit quality deterioration in tea plant buds, leaves and stems (branches) and fruit tree buds, leaves, stems and fruits in a field (tea plantation) or orchard. (Protection and breeding) devices and methods thereof, for example, during the most difficult period as a crop, from the pre- and post-emergence period to the flower-bud growth period, and at the time of extremely high relevance to yield, quality, etc. Further, the present invention relates to a device for the growth and growth and protection of fruit trees (avoidance of frost and frost damage on tea trees or fruit trees ) using a defrost fan and other equipment, and a control method thereof.

  Regarding the freezing resistance (safe temperature limit) of crops, for example, tea, the following explanation is given in the book. The freezing resistance (mainly the freezing resistance of leaf cells) is as follows from the growth stage of tea. Within one month before germination, approximately 50% is supported at -9 ° C at the body temperature. After that, two weeks before the germination, it is supported in the same manner at −5 ° C. Further, immediately before sprouting, it is supported in the same manner at −3 ° C. Furthermore, in the 1st to 2nd leaf stage, it is similarly supported at -2 ° C. Note that the plucking period is supported in the same manner at −2.5 ° C. In addition, in the leaves of tea, the upper leaves (upper leaves) are lower in freezing resistance than the lower leaves (lower leaves), and the new shoots are similarly supported at −2 ° C. This is a concept that captures the so-called freezing resistance support assuming the growth stage (growth process) of tea. Or it is temperature management by the sensor deployed in the field etc., and when the observation is at 18:00, the dry bulb temperature is 7.5 ° C, the wet bulb temperature is 5.5 ° C, and the humidity is 72%. If there is, tomorrow's minimum temperature is estimated to be approximately 0.4 ° C. This is a concept that can be understood as a rule of thumb.

  In addition, a method for considering frost resistance in advance (a means for predicting) has the following explanation in a book. In other words, it is said that it is desirable to determine the frequency of risk of freezing resistance based on how many days the minimum temperature is −3 ° C. or less after the budding as a means of prediction. In other words, the so-called frost resistance can be grasped based on the temperature integrated value.

As a means for ensuring the safety limit temperature, a general and simple means among conventional means is a method in which the air (warm air) of the inversion layer is blown (blows down) by a defrost fan. And / or a hot air machine. In addition, part of the water is sprinkler water that is supplied or dripped onto the foliage and / or soil and culture medium, using the latent heat when the water freezes, This is a method to avoid cell destruction. Although its effectiveness is conceivable, there are problems (disabilities) such as post-treatment of water supply and water treatment, so it is only implemented as a research topic. Furthermore, methods for scientifically supporting frost resistance are also disclosed in part in the literature described below.
In the current method for avoiding frost and frost damage, the anti-frost fan is operated at a temperature lower than the set temperature. However, the frost-proof fan is operated even in weather conditions where frost and frost damage does not occur. As a result, the electricity bill is excessive and the burden on the farmer is large, the apparatus is easily deteriorated and damaged, and the life is shortened. In some areas, in order to reduce the frequency of use of frost-proof fans, for example, there are areas where the temperature setting for each growth stage is performed based on experience and customs, but it is not fully utilized. That is, there may be room for improvement with respect to the temperature setting for each growth stage, the control of the defrost fan based on this temperature setting, and the control of other effective means (for example, a warm air machine).

  The applicant of the present invention has made many inventions convinced that the above various conditions are satisfied and effective. As an example, the invention described in Japanese Patent Application Laid-Open No. 2008-35775 is used, and by using an HL sensor (high / low sensor) to control on / off of the defrost fan, it is possible to prevent outside frost and freeze leaves. Intended to slow freeze (slow thaw) cells. Moreover, it is an invention described in Japanese Patent Application Laid-Open No. 2008-5738, and by using inspection equipment such as an HL sensor, a rain sensor, or a water drop sensor, and a surveillance camera, on / off control and on / off control of the defrosting fan are precisely performed. By executing, it is intended to avoid cell destruction, increase the efficiency of air blowing, and / or secure a growth environment. In addition, as an example of another company, it is an invention described in Japanese Patent Laid-Open No. 2-44500, which collects regional weather conditions in multiple ways and uses this multiple information to prevent frost, water intake, water discharge, etc. Plan.

  FIG. 1 is a schematic view showing an example of a defrosting fan 1 (fan) of the present invention. The defrosting fan 1 is a fan for defrosting, defrosting, and thawing, and is provided in a generally called reverse layer X. ing. The anti-frost fan 1 is provided with a fan 2 and a motor 200 for the fan 2. Therefore, the fan 2 is blown and the blow is stopped (ON / OFF control) by ON / OFF control of the motor 200. Reference numeral 3 denotes a temperature sensor, 5 denotes a hot air machine, and a heater (hot air machine). W represents a crop (tea, fruit), and W2 represents a tea bowl. 6 indicates a building pillar, and Y indicates the movement of the wind. The temperature sensor 3 is located below the building pillar 6 or at a location where the wind of the fan 2 does not hit and is not affected by the warm air fan 5, and is located inside the field A. If necessary, the leaf surface W1, Buds or stems and their vicinity (single or plural). In the drawing, although it seems that the wind of the warm air machine 5 is hit, it is schematically shown. The fan 2 is not provided with a guard, but there is a structure in which a guard is provided.

  In addition, as shown in FIG. 4, the duct 4 is attached between the teacups W2 (one example) of the warm air machine 5, and the warm air is efficiently and directly blown to the leaf surface, the tea tree, the tea branch, and the like. You can also. Although not shown, the same applies to fruit trees and the like. The duct 4 may be provided with a plurality of outlets 400 or a means for opening the tip.

The integrated temperature is an integrated value of a temperature equal to or higher than the integrated reference temperature (that is, the difference between the average temperature of the day and the integrated reference temperature). For example, in the case of a tea plant in a farm field A at a certain place, when considering from January 1, the integrated value shown in FIG. 5A is obtained. From this 0, the growth stage is determined from the integrated value of 500 ° C. In this example, the integrated value is as follows.
0 to 40 ° C. is before germination 40 to 80 ° C. is germination period 80 to 120 ° C. is one leaf stage 120 to 180 ° C. is two leaf stage 180 to 220 ° C. is trilobal phase 220 to 300 ° C. is four leaf stage. The five-leaf stage of 300 ° C. is determined based on the chart shown in FIG.

  Accordingly, the fan 2 is ON-controlled when the temperature of the field A becomes equal to or lower than the set temperature. In one example, the fan 2 is turned on and off as compared with the set temperature shown in claim 5 and FIG. The control unit 7 compares the set temperature of the current growth stage with the current temperature shown in FIG. 5B, and in principle, adopts each means by relative control. For example, when the temperature is equal to or lower than the set temperature, the fan 2 is moved to protect the crop W from frost damage, and the device can maintain the growing environment and the fruiting environment of the crop. The present invention will be described sequentially based on the following ideas and examples.

  Based on the example shown in FIG. 5-1, in the chart of FIG. 5-2 showing the relationship between the set temperature in the growth stage of the crop W and the integrated value, the vertical axis is compared with the current temperature by the control unit 7. The abscissa indicates the set temperature to be set, and the abscissa indicates the integrated value, indicating the stage from the germination period to the harvesting period. For example, in the chart of Fig. 5-1, January 29 is the germination period, and from the chart of Fig. 5-2, the set temperature of the germination period is 2 ° C, and this set temperature 2 ° C is compared with the current temperature. When the set temperature is 2 ° C. or lower, the fan 2 is turned on, and the air in the inversion layer X is blown down (warm air is blown down as warm wind). The growth environment and fruiting environment of the crop W can be maintained. In the experiment so far, in this germination period, the freezing resistance of the crop W is set to −3 ° C., and the present temperature is compared with the set temperature 2 ° C. as described above by the method of the present invention. When the temperature is lower than 2 ° C., the growth environment and the fruiting environment can be maintained by turning on the fan 2. The purpose of the operation of the fan 2 is as follows (the same applies hereinafter). From FIG. 5-1, March 12 is the first leaf stage, and from FIG. 5-2, the set temperature of the first leaf stage is 3 ° C. When this set temperature of 3 ° C. is compared with the current temperature and lower than 3 ° C., the fan 2 is turned on and the air in the inversion layer X is blown down. The growth environment and fruit setting environment of crop W can be maintained. In the experiments so far, in this one-leaf stage, the freezing resistance of the crop W is set to −2 ° C., and as described above, the current temperature is higher than 3 ° C. in the method of the present invention. When the temperature is low, the fan 2 can be turned on to maintain the growing environment and the fruiting environment. Generally, prior to plucking, it is most necessary to pay attention to temperature control. For example, April 10 is the fourth and fifth leaf stages, and the set temperature is 6 ° C. from FIG. When the current temperature is lower than 6 ° C., the fan 2 is turned on and the warm air of the inversion layer Z is blown down as a warm wind. The growth environment / fruiting environment of the crop W can be maintained at least from the first leaf stage (most tea) to the fifth leaf stage. In the experiments so far, before the picking, the freeze resistance of the crop W is set to −2.5 ° C., and the method of the present invention is adopted, and as described above, the fan 2 By turning it on, it is possible to maintain a growing environment and a fruiting environment.

For example, as in claim 5, the control unit 7 is configured to compare the set temperature for control of the fan 2 (frost prevention fan 1) with the current temperature.
The set temperature until the germination stage of the growth stage has little influence, for example, 1 ° C,
The set temperature of the previous stage of the growth stage is 1 ° C., and even if the fan 2 is moved, the current temperature lower than 1 ° C. (for example, (set temperature (1 ° C.) − 2 ° C. = − 1 ° C.)) When the sprinkler 10 or the warm air machine 5 is moved.
The set temperature for the germination stage of the growth stage is set to 2 ° C. When the current temperature is lower than this (for example, (set temperature (2 ° C.) − 2 ° C. = 0 ° C.)), the sprinkler 10 or the warm air machine 5 is moved.
The set temperature at the one-leaf stage after germination of the growth stage is 3 ° C., and at a current temperature lower than this (for example, (set temperature (3 ° C.) − 2 ° C. = 1 ° C.)), even if the fan 2 is moved, 3 When the temperature does not recover, the sprinkler 10 or the warm air machine 5 is moved.
If the set temperature of the 4th and 5th leaf stage before the growth stage is 6 ° C and the current temperature is lower than this (for example, (set temperature (6 ° C)-2 ° C = 4 ° C)), the fan 2 is moved. When 3 ° C. is not recovered, the sprinkler 10 or the warm air fan 5 is moved. Note that when the sprinkler 10 is moved, the fan 2 can be stopped.

  Control is performed based on this set temperature. This control is performed at least by turning on / off the fan 2, “maintaining the growing environment / fruit setting environment with the fan 2 as the center and the fan 2, and at a lower temperature, the sprinkler 10 and / or The warm air blower 5 is turned on and off, so that it has the effectiveness that can be reliably executed and can achieve its purpose reasonably. Also, it can avoid disease around the crop (tea) and improve the quality. " There are features. When the temperature is lower, it is desirable that the sprinkler 10 is first turned on and off, and the warm air fan 5 is turned on and off. The reason for this is the relationship between cost, empirical rules, and incidental facilities.

Next, in the fruit tree of the other crop W, the growth stage can be determined from the integrated value as shown in FIG.
In this example,
200 ° C is the germination stage 200-380 ° C is the leaf spreading stage 380-500 ° C is the flowering stage Based on this growth stage (integrated value), the set temperature is determined based on the chart shown in Fig. 5-4. decide.

  Based on the growth stage of the fruit tree, the set temperature is determined based on the chart shown in FIG. 5-4. The control unit 7 compares the current temperature, moves the fan 2, and when the temperature of the field A becomes equal to or lower than the set temperature, ON control is performed. In one example, the fan 2 is turned on and off as compared with the set temperature shown in claim 6 and FIGS. The control unit 7 compares the current set temperature of the growth stage shown in FIG. 5-4 with the current temperature. If the temperature is equal to or lower than the set temperature, the fan 2 can be moved to maintain the growing environment / fruiting environment of the crop W. The present invention will be described based on the following ideas and examples. In basic temperature management, after budding (after germination), in principle, it is convenient to perform control by raising the temperature by 1 ° C. per week, and simple and smooth operation can be performed.

  In the fruit tree of the other crop W, the control unit 7 compares the set temperature with the current temperature from the growth stage, and if the current temperature is lower than the set temperature, the fan 2 is operated to reliably grow the crop W in the field. The environment and fruiting environment can be maintained. Based on the following ideas and actual examples, the crop W will be sequentially described based on the examples shown in FIGS. 5-3 and 5-4.

For example, as in claim 6, the control unit 7 is configured to compare the set temperature of the control of the fan 2 with the current temperature.
The set temperature until the germination stage of the growth stage has little influence. For example, even if the fan 2 is moved, the current temperature lower than 1 ° C. (for example, (set temperature (1 ° C.) − 2 ° C. = − 1 ° C.)) Sometimes, the sprinkler 10 or the warm air machine 5 is moved.
The set temperature in the leaf stage of the growth stage is 2 ° C., and if the current temperature is lower than this (for example, (set temperature (2 ° C.) − 2 ° C. = 0 ° C.)), the sprinkler 10 or the warm air fan 5 is moved.
The setting of the flowering stage of the growth stage is 3 ° C. Even if the fan 2 is moved, if the current temperature is lower than this (for example, (set temperature (3 ° C.) − 2 ° C. = 1 ° C.)), the sprinkler 10 or the temperature In this configuration, the fan 5 is moved. Note that when the sprinkler 10 is moved, the fan 2 can be stopped.

  Figure 5-5 is based on the data from the Agriculture Promotion Division, Fukushima Prefecture Agriculture, Forestry and Fisheries Department in FY2013. For example, the order of the growth stage is germination period, flower red color, petal exposure, flowering, full bloom period, flowering end period, and the like. An example of the state and date / time (schedule) in the order of the development stage is shown. Moreover, the kind of the crop W has shown the apple.

  Control is performed based on this set temperature. This control is performed at least by turning the fan 2 ON / OFF, and “the growth environment and fruiting environment maintenance is covered by the fan 2 and the fan 2, and when the temperature is lower than the set temperature, the hot air fan 5 And / or the sprinkler 10 is turned on and off, so that it can be reliably executed and the purpose can be achieved reasonably.In addition, disease avoidance around the crop (fruit tree) and quality improvement Alternatively, when the temperature is lower than the set temperature, it is desirable to turn on / off the warm air fan 5. Others are in accordance with the above-mentioned claim 5.

  The present invention is based on the freeze resistance of the crop surface W and / or the leaf surface W1 of the growth stage, and the control unit 7 is provided with a set temperature (at least a numerical temperature exceeding 4 to 5 ° C.) that exceeds the freeze resistance. It is possible to reliably maintain the growth environment and fruiting environment of the crop W in the field A. Thus, it is important to set a preset temperature that surpasses frost resistance in the control unit 7.

  FIG. 2 is an embodiment in which a humidity sensor 8 is installed in the vicinity of the leaf surface W1 of the crop W. When the humidity sensor 8 is below (or above) the set temperature in the growth stage according to claim 2, the humidity sensor 8 is above a predetermined level. When the humidity is detected, the fan 2 is turned on via the control unit 7 to secure the wind flow around the leaf surface W1, branches, trunks, trunks, stems, etc. and / or directly. it can. In addition, when the leaf surface W1 is frozen, the fan 2 is turned on and the frozen leaf cells are slowly frozen (slowly thawed) to avoid cell destruction. When the fan 2 is turned on, for example, it is possible to maintain the growth environment and the fruiting environment of the crop W and to avoid the occurrence of pests and the like, as well as to avoid the occurrence of pests.

  FIG. 3 is a schematic view showing an example in which a large number of sprinklers 10 are installed in the field A, and a large number of the sprinklers 10 are erected between the teacups W2. In addition, although not shown, the sprinkler 10 may be installed on the building pillar 6 and / or the frost-proof fan 1 provided at an appropriate place in the field A. The sprinkler 10 may be installed in the vicinity of or directly on the leaf surface W1, the stem, the branch, the trunk, or the like. Note that the installation of the sprinkler 10 in the orchard follows the installation of the farm A. Water (water supply) by this sprinkler 10 is supplied or dripped onto the leaf surface W1 and / or soil and culture medium, utilizing the latent heat generated when the water freezes, and ensuring that the temperature does not fall below about 0 ° C. In order to maintain the growth environment and the fruiting environment (avoid frost damage) or thaw, the fan 2 is used to slowly freeze frozen leaf cells to avoid cell destruction. In consideration of the post-treatment of water supply in consideration of the effectiveness, it can be performed evenly over the entire field A, or regarding problems such as water treatment, combined use with the warm air fan 5 or the defrost fan 1 after water supply Considering the temporary operation, adopt an effective method. In addition, the water supply is effective in removing obstacles such as salt in other cases, for example, in soil and culture medium.

  In the above description, an example in which the frost-proof fan 1 and the warm air fan 5 or the sprinkler 10 are used comprehensively has been described. However, it is possible to select from these three types or, depending on circumstances, various types such as single use. It is possible to combine and always select and implement the optimum use. Although not shown, the wind sensor is the same.

  FIG. 6 shows an integrated value at each growth stage of the crop W and a sensor value of a temperature / humidity sensor or a wind speed sensor (not shown) in accordance with an instruction from the control unit 7 and fan control and / or the field A. Or an operation that enables control of the hot air fan 5 or sprinkler 10 deployed in an orchard (not shown) (or, although not shown, enables control of the hot air fan 5 and / or sprinkler 10) FIG. As in (a), the current temperature / humidity data from the temperature / humidity sensor is input to the control unit 7, and the frost-proof fan 1, the warm air fan 5, or the sprinkler 10 is individually controlled or selectively selected. The configuration is intended for control or combination control. In (b) temperature management, temperature management is performed by means of (ST-1)-(ST-3), and the data is input to the control unit 7. In the control unit 7, the temperature setting (value) is determined based on the growth stage, and whether or not the defrosting fan 1 is ON is determined based on the temperature setting by means of (ST-3) and (ST-4). To do. For example, as in (ST-6), when the temperature around the crop W is low or in the vicinity thereof (freezing resistance is threatened or probable), the control unit 7 performs (ST-6), (ST As in -7), the frost-proof fan 1 is operated. In (ST-8), it is determined whether the warm air fan 5 and / or the sprinkler 10 is ON. And it becomes the driving | operation of the warm air machine 5 (it writes as a heater) of (ST-9), or the driving | operation of the sprinkler 10. FIG.

  In the above (ST-8), when the temperature around the crop W is high or in the vicinity thereof (freezing resistance is supported or likely to be secured), the warm air fan 5 or the sprinkler 10 stops and stands by. It becomes a state. In (ST-6), when the temperature around the crop W is high (freezing resistance is carried), the fan 2 stops and enters a standby state.
