Description

  The present invention relates to a rectifying shutter with an insect net of a house.

  Recently, crops such as vegetables, leaf vegetables, fruits, flowers, etc. that are pesticide-free are useful. This kind of pesticide-free cultivation (including reduced pesticides) is indispensable when considering the general viewpoint and / or the global environment in consideration of the health of people, recovery of diseases, or agriculture in Japan. It is. From this point of view, cultivation methods using insect repellent nets are becoming mainstream in house cultivation. However, conventional insect nets capture pests that invade from the shutter and reduce pesticide use to keep the amount of pesticides used in the house without entering the house, or completely pesticide-free cultivation (reduced pesticide cultivation, pesticide-free cultivation and Only). Therefore, it is only a one-sided improvement.
