Description

  The present invention relates to a crop cultivation method using a defrost fan and a defrost fan device used in this cultivation method.

  Conventionally, for fruits such as apples, pears, persimmons, peaches, etc., it is desired to expand the harvest of high-quality fruits, such as ensuring fruit set, reducing rust fruit, promoting fruit enlargement, and ensuring fruit shape. Has been. Also, reducing the use of pesticides and protecting the environment are important issues. The same is true for vegetables, and various methods are employed for this purpose. As one of them, a frost-proof fan is known as a simple and energy-saving method for effectively using natural climatic conditions. This frost-proof fan has also evolved from a frost-proof fan device provided on a building pillar to a liftable frost-proof fan device. In this evolution process, a frost-proof fan device intended to achieve a multi-face frost-proof effect by controlling the depression angle and / or trajectory of the frost-proof fan has been proposed. He has been deeply involved in fan devices and / or improvements.

  As part of this trend, the market has further evolved frost-proof fan equipment to ensure high quality, such as ensuring fruit set, reducing rust fruit, promoting fruit enlargement, and ensuring fruit shape. There is a need for a method to expand the fruit harvest.

  In view of the above-mentioned viewpoints, conventional documents that can be related are listed. This document mainly relates to crop cultivation methods and is outlined below.

  First, the literature (1) is Japanese Patent Application Laid-Open No. 2004-222553 “Cultivation method of pesticide-free cherry peaches”. This document (1) has the following explanation. “In fruit tree cultivation, pesticides are sprayed from the viewpoint of pest control. Usually, pesticides are sprayed many times a year. However, fruit trees are crops that are harvested in the middle of growth, such as vegetables. Contrary to this, because it is a perennial crop, the maintenance of the tree is important, disinfection is indispensable, and there are problems such as the death of the tree if left untreated, or the inability to harvest high-quality fruits As a pest control standard for moths, peaches, etc., farmers should spray pesticides 9 times for moths, 13 times for peaches, 14 times for apples, 15 times for pears, and 8 times for cherry peaches. And if you use house cultivation instead of outdoor cultivation, the number of spraying of pesticides throughout the year is more than that of outdoor cultivation. Present in Pests such as mites and astronomical fungi, and insect pests such as Drosophila are more likely to be generated, and in the case of house cultivation, there are more patterns to harvest faster than open field cultivation. It has been disclosed that the harmful effects of spraying pesticides are even more serious because the pesticides are sprayed many times because the outside air temperature becomes high during this period and the mites are more likely to occur. .

  Reference (2) is a republished patent WO2002 / 023974 "Plants with improved resistance to various environmental stresses, methods for producing them, and polyamine metabolism-related enzyme genes". This document (2) has the following explanation. “Plants live by adapting to various environmental stresses such as temperature and salt in their habitats. However, in temperature stress, for example, they encounter an environment where the plant exceeds the upper limit or lower limit of the optimum growth temperature. Then, under high or low temperature stress, the physiological function of the cells is gradually or suddenly damaged, causing damages.To use wild plants adapted to various temperature environments for food crops and craft crops, etc. In addition, we have endeavored to expand the temperature adaptability of crops by breeding means such as selection and cross breeding, etc. In addition to breeding means, horticultural crops such as vegetables, petals and fruit trees can be cultivated in facility horticulture. However, in Japan, the climate varies significantly from region to region, and changes in the four seasons are significant. There is a possibility of being exposed to the environment, for example, there are many crops of tropical origin among tomatoes, cucumbers, melons, etc. Recently, it has been incorporated into cultivation, but resource saving in facility horticulture and reduction of heating costs have become a problem, and resource conservation in facility horticulture has been studied from various aspects, from structural greenhouses to cultivation techniques. However, the most basic is to increase the tolerance of crops to low-temperature stress, or in recent years, it has been known that crops are severely damaged by extreme weather that may be caused by global warming or El Niño phenomena. "

  Further, the document (3) is “A method for quick cultivation of greenhouse melons in a cold region” of JP-A-1-171415. This document (3) has the following explanation. “In Hokkaido, it is suitable for cultivation of greenhouse melons because of the ease of humidity control and / or the occurrence of mildew and bacteria in the road without rainy season. Therefore, the present invention has the disadvantage that the temperature of the soil is low, so this invention avoids chilling at night and the temperature in the soil near the first fruiting position of the melon seedling by piping a heat medium in the soil. And intended for early shipment. "

JP2004-222553 WO2002 / 023974 JP-A-1-171415

FIG. 8A is an enlarged side view of the main part of the example of FIG. 6, and FIG. 8B is a rear view of FIG. Fig. 9 shows the position of the frost-proof fan used in the continuous house, with the building pillar with the frost-proof fan set at the maximum angle and the rain proof (insect repellent, shading etc.) tent open. FIG. 10 is a position where the frost-proof fan is used in a continuous house, where the building column with the frost-proof fan having a depression angle of 0 is contracted to the minimum and rain repellent (insect repellent, light shielding, etc.) FIG. 4 is a schematic back view showing a state in which a tent is stretched.

  1 to 3, FIG. 7-1, FIG. 7-2, and FIG. 9 are the frost-proof fan use position of the house, and the building pillar H in which the depression angle of the frost-proof fan is set extends to the maximum. And each figure showing a state in which the rain protection tent is opened, the frost-proof fan A1 of the frost-proof fan device A is maintained at the depression angle B, and the warm air D of the ground GLL is blown down to the crop W. Therefore, the tent C is open because it is the height of the building pillar H. This is a so-called outdoor cultivation state. By using the defrost fan A1 in this state, air can be diffused to prevent, for example, a decrease in plant body temperature and avoid a temperature difference from the air temperature, and a defrost effect and growth can be promoted.

The frost-proof fan A1 of the frost-proof fan device A maintains the depression angle 0 (B = 0), and the warm air D on the ground GLL is blown horizontally to the crop W D1. Since the building pillar H is low, the tent C is stretched. This is a so-called house cultivation state. It is effective for preventing actual cracking, and the various effects described above can be expected. Moreover, the ventilation D1 to the back surface of the leaf surface is also possible, which is effective in preventing wetting and / or wilting. 1 to 3, FIG. 7-1, FIG. 7-2 and FIG. 9 may be repeated in the weather and / or other situations even after fruiting.
