Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a winter hat for agricultural products for protecting agricultural products from the cold of the outside air.

[0002]

2. Description of the Related Art When the temperature drops significantly in the autumn or winter, the agricultural products exposed to the open air are subject to frostbite due to the cold, and leaves and fruits are discolored, which may impair the commercial value.

Therefore, conventionally, as shown in FIG. 4, a agricultural product a such as Chinese cabbage is covered with a newspaper b, or as shown in FIG. 5, the agricultural product a is taken out from the field with roots and piled up. In addition, the mountain c of the agricultural product a is covered with the straw c and then the embankment d is applied to protect the agricultural product a from the cold.

[0004]

However, when the agricultural product a is wrapped with the newspaper b as in the former case, the newspaper b is easily broken and it is difficult to wrap the agricultural product a, so that the workability is poor and the newspaper paper wrapping the agricultural product a is also difficult. Since the lower part of b must be bound with straw, string e, etc., it is very troublesome and heavy to perform such work for each of the many agricultural products a planted in the field. There was a problem.

In the latter case, when a pile of agricultural products a extracted from a field is piled up with straw c before embankment, the metabolism of the agricultural product a becomes inactive and the freshness is deteriorated. In addition, especially when the agricultural product a is Chinese cabbage or the like, when rainy weather continues, a part of the embankment d penetrates into the inside and enters the gap between the leaves, resulting in a significant decrease in commercial value.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an agricultural product overwintering hat capable of easily covering an agricultural product just planted in a field with good workability to protect the agricultural product from the cold. .

[0007]

The present invention provides a winter hat for agricultural products characterized in that a net made of a flexible heat insulating material is formed into a bell shape having an opening at a lower portion and an upper portion closed. , Are related to.

The flexible heat insulating material forming the net is preferably a foamed resin, and the mesh of the net is preferably formed in a rhombus shape which is flat in the circumferential direction when not in use.

Further, it is possible to add an agricultural chemical to the flexible heat insulating material constituting the net, and it is preferable to adopt a biochemical as the agricultural chemical.

[0010]

Therefore, in the present invention, by covering each agricultural product by covering each agricultural product planted in the field with the agricultural product wintering hat, it is possible to protect the agricultural product from the cold of the outside air in autumn or winter. Become.

The work of covering the produce wintering hat on the produce is
Since the winter hat for agricultural products is formed in a bell shape from the beginning, it is only necessary to cover each agricultural product, and the wintering hat for agricultural products remains wrapped around the agricultural products without having to tie it with straw or a string. Even if it is held and blown by the wind, it does not easily come off the produce.

Furthermore, it is possible to protect agricultural products from the cold while planting them in the field, and the mesh keeps good air permeability.

If the flexible heat insulating material constituting the net is made of a foamed resin having excellent corrosion resistance, it can withstand wind and rain for a long period of time, and can be reused repeatedly by washing and sterilizing. It becomes possible to do.

Further, if the mesh of the net is formed in a rhombus shape that is flat in the circumferential direction when not in use, it is possible to give the agricultural product wintering hat a stretchable function with resilience in the circumferential direction.

If the pesticide is contained in the flexible heat insulating material forming the net, it is possible to control pests without directly spraying the pesticide on the agricultural products.

Furthermore, when a biopesticide is used as the pesticide to be contained in the flexible heat insulating material constituting the net, the effect on the ecosystem is significantly suppressed.
