Abstract

(57) [Summary] [Purpose] A double bag for peach cultivation that suppresses sunburn without affecting fruit maturity. [Structure] The inner bag 1 is made of paper that is colored in cream with a dye or pigment that fades in a few days by direct sunlight.

Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to a double bag used for peach cultivation.

[0002]

[Prior art]

 The outer bag of the double bag for peach cultivation is intended to suppress the growth of chlorophyll in the fruit by keeping the growth period in the shaded state like other fruits, and the bag is automatically removed by growing the fruit. The inner bag is intended to prevent the occurrence of fruit cracking due to direct sunlight irradiation, rain and condensation of water droplets due to dew condensation, and coloring defects, and it is transparent until harvesting. It is intended to be covered with an inner bag provided.

Since peaches have shorter fruit stems than apples and the like, fruit bags are attached to branches. Considering attachment to branches and removal of outer bags, the outer bag is better than the inner bag. The structure is short and has a notch at the upper edge of the inner bag exposed part for inserting fruit tree branches.

[0004]

[Problems to be solved by the device]

 By the way, the inner bag of the conventional double bag for peach cultivation is intended to prevent direct sunlight and to prevent water droplets from adhering to it. Had a total light transmittance of 64.2%). However, the rapid change in the irradiation light when the outer bag is removed easily causes sunburn on the fruit. Therefore, the present invention proposes a new double bag for peach cultivation that suppresses the occurrence of sunburn.

[0005]

[Means for Solving the Problems]

 The double bag for peach cultivation according to the present invention comprises a double bag including an inner bag and an outer bag having a shorter length than the inner bag, and a notch for inserting a fruit tree branch on the upper edge of the exposed inner bag. In a double bag for peach cultivation with a part formed, the inner bag is made of paper that is colored in cream with a dye or pigment that fades within 2 to 3 days under direct sunlight. To do.

[0006]

[Action]

 Since the inner bag is colored in cream color, the irradiation light on the fruits is reduced when the outer bag is removed (compared to a white paper inner bag). Occurrence of the fruit has been reduced by 20 to 30%, and the cream color fades within a few days to a pale white color as before, so the fruit coloring is the same as before.

[0007]

【Example】

 Next, an embodiment of the present invention will be described. The double bag shown in the embodiment has the same structure as that of the conventional double bag and is composed of an inner bag 1 and an outer bag 2 in which a whole or a part of a tubular or lower edge is sealed. , Inner bag 1 is a dye or pigment that fades in 2 to 3 days under direct sunlight of the sun and is made of cream-colored paper (total light transmittance 57.5%) and has grown. It has a size enough to wrap the fruit A, and a notch 11 for inserting a fruit tree branch is formed at the upper edge, and a wire 13 for attaching a branch is provided in one of the ears 12 on both sides of the notch 11. Further, the entire both sides are folded inwardly (having a folding portion 14) so that the bag can be slenderly stored in the outer bag 2.

The outer bag 2 is made of paper having a sufficient light-shielding property, has a shorter length than the inner bag 1, has tearing perforations 21 provided vertically, and forms an island-shaped portion 22 near the upper edge. The inner bag 1 that is folded is provided with a cut 23, and the back surface of the island-shaped portion 22 and the inner bag 1 are glued to each other.

Then, while covering the young fruit A with the double bag, the branch B is passed through the notch 11, the opening is closed by the ear 14, and the wire 13 is fastened to carry the bag. By the growth of the young fruit A, the folded portion 14 of the inner bag 1 is pushed and expanded, the outer bag 1 is torn from the perforation 21 portion, and the outer bag 1 is connected to the inner bag 1 at the island-shaped portions 22 and By pulling the bag 2, the main body of the outer bag 1 and the island-shaped portion 14 are separated along the notch 23, and the outer bag is removed.

When the outer bag is removed, the fruit A is exposed to sunlight through the inner bag, but the inner bag 1 is a dye or pigment that fades in 2 to 3 days by direct sunlight and is a cream. Since it is colored, the temperature inside the bag is about 2 ° C lower when the outer bag is removed compared to the conventional white inner bag, which further suppresses the occurrence of sunburn. Furthermore, when the irradiation light is appropriately blocked, the coloring material fades in a few days, so that there is no problem in coloring the fruit. The paper used for the inner bag as an example has a total light transmittance of 57.2% before fading, but if the light transmittance is at least in the range of 60 to 55%, the paper will be less than that of the conventional white inner bag. It was observed that the effects were clearly different.

[0011]

[Effect of the invention]

 As described above, the present invention relates to a double bag for peach cultivation, in which the inner bag is made of a cream-colored paper with a dye or pigment that fades in 2 to 3 days under the direct sunlight of the sun. It is a product that has not been affected by maturation of fruits such as coloring the fruits at all, and further suppresses the occurrence of sunburn of the fruits when the outer bag is removed.
