The present invention relates to a problem in that the watermelon is exposed to direct sunlight in the summer season, especially at the time of shipment, and becomes a fruit (fruit dame phenomenon), and the fleshy malignancies (blood watermelon) and physiology inside the watermelon due to excessive direct sunlight exposure. The cultivation method that suppresses the occurrence of impaired watermelon and the optimal fruit cover to prevent the cultivation method used in the cultivation method are to be developed.

The present invention provides the following problem solving means in order to solve the above problems.

It provides a method of cultivating watermelon, characterized in that the watermelon is wrapped around 10 days before harvesting in a high temperature season with a fruit cover for preventing fruit spoiling, which is composed of a nonwoven fabric having a density of 40g/㎡ or 50g/㎡.

In addition, the fruit cover for preventing fruit spoiling is an inscribed circle by forming a wrinkle on the edge of a nonwoven fabric having a density of 40 g/m 2 or 50 g/m 2 with a radius of 34 to 37 cm for the production of large fruit species with a fruit weight of 8 to 10 kg. Note: Provides a fruit cover to prevent fruit burns to prevent fruit burn, characterized in that it is folded so that the length is 50 to 52 cm, and combined with an elastic elastic band and stitching.

The rubber band provides a fruit cover for preventing fruit damage, characterized in that the goal band rubber band.

It is characterized in that it further comprises a fruit pedestal for preventing contact between the watermelon and the bottom surface is formed of a circular plastic at the lower portion of the fruit cover for preventing fruit burn.

It provides a watermelon scatter prevention fruit cover for preventing fruit scum, characterized in that a watermelon transport net for shipping watermelons after harvesting is built into the inside of the watermelon scatter prevention fruit cover for preventing fruit scum.

Watermelon for prevention of sweeping fruit cover of the present invention targets watermelon cultivated in the open field and rain-covered house. Watermelon) and physiological disorders Watermelon has the effect of suppressing the occurrence.

In addition, there is a preventive effect of pests that damage fruits such as cotton monarch moth or pabam moth.

The present invention was invented for the purpose of suppressing the occurrence of physiological disorders, such as ilso (fruit daim) and fleshy malignancies (blood watermelon) of watermelon cultivated in open-air and rain-garim houses during high temperatures.

For this

[Example 1]

An experiment was conducted to develop a cover cover for fruit protection to alleviate physiological disorders during cultivation of watermelon at high temperatures.

end. Test period and test area: 2017~2018, cultivation of watermelon fisheries in Gochang-gun, Jeollabuk-do

I. Test varieties: Seedless, water (sambok honey, empty space planting in ridge, 10:1)

All. Settlement day: set meal) 5. 1. → harvest) 7. 27.

la. Cultivation method: Planting distance 250*50cm set meal, 3 stems inducement, 3 fruiting (bee fertilization)

※ Fertilization amount (kg/10a): Standard fertilization of open-water watermelon

N(20.0)-P ₂ O ₅ (5.9)-K ₂ O (12.8)-Compost (1,500)

hemp. Processing contents

Newspaper (Daejo-gu): It is preferred by farmers because it is easy to purchase materials and is inexpensive, but it is not easy to wrap the whole fruit and there is an inconvenience of re-installing the newspaper because it is torn by rainwater during the rainy season.

Rice straw: Unlike in the past, it is difficult to purchase materials as the use of it increases for livestock feed, and there is a disadvantage that the coating is peeled off by the wind after coating, so there is an inconvenience of having to be repeatedly coated. Due to its characteristics, it has good ventilation.

Non-woven fabric: 40g and 50g/m2 for nails were used as a white non-woven fabric with a light-shielding rate of 30%, and good ventilation.

Light-shielding net: 3 types (black, blue, and white) were used for the contrast, light-shielding rate: 35%, and good ventilation.

* The fruit protection cover was installed 10 days before the harvest of watermelon.

bar. Survey items: illuminance, temperature by growth stage, growth characteristics, physiological disorders (e.g., ilsodae, meat quality characteristics, etc.), pests, and quality characteristics were investigated.

[Example 2]

Experiment result

end. Weather changes during the test period

4 shows changes in illuminance and temperature during the experiment period of the present invention. Except for 1 day, it shows a high temperature of 30 degrees or more and an illuminance of 100,000 lux or more.

I. Key results (2017~2018)

-Harvester fruiting characteristics by type of fruit cover (for preventing fruit scum)

(Investigation date: 7. 27.)

DMRT(0.05)

DMRT compares all means while maintaining the determined significance level (a = alpha) regardless of the number of means, and this is called Duncan's multiple range test (DMRT).

In the present invention, watermelon was fruited using bees, and the fruiting took about 10 days, and there was no significance in the fruit paste, fruit cut, and soy sauce.

-Leaf growth characteristics at harvest season for each type of fruit cover for prevention of fruit fruit (fruit dame)

(Investigation date: 7. 27.)

z DMRT(0.05)

· Leaf length and leaf length were not significant, but leaf width and leaf area were significant.

-Harvester fruit characteristics by type of fruit cover to prevent the phenomenon of ilsofruit (fruit daim)

(Investigation date: 7. 27.)

z DMRT(0.05)

·Overweight was 7.8~9.0kg, and there was no significance in exaggeration and overwidth, but significant in skin thickness and navel size. This was judged to be related to the evaporation of moisture from the fruit due to direct sunlight.

-Harvester pulp temperature for each type of fruit cover to prevent fruiting (fruit dame)

(Investigation date: 7. 27.)

·No damage occurred in newspaper, straw, and non-woven fabric treatment, but 100% occurred in shading net (35%) treatment. It was judged as a result of the lack of direct sunlight blocking effect of the shading net.

·The temperature of the pulp was 29~42.1℃ in the damaged part, which was higher than that of the surrounding part, and there was a clear difference in the newspaper at 42.1℃. Therefore, just by lowering the temperature of the part where direct sunlight is closed, the damaged part of the flesh can be reduced.

-Changes in sugar content during harvesting by type of fruit cover to prevent fruiting (fruit dame)

(Investigation date: 7. 27.)

The sugar content was 12.5-13.8°Brix in the center, higher than 9.7-12.9°Brix in the periphery, and the sugar content of the shading net was higher and the fruit weight was small. Was judged.

-Changes in fruit hardness during harvesting by type of fruit cover to prevent fruit burn

(Investigation date: 7. 27.)

·The hardness of the pulp tended to be higher in the affected area and the periphery than in the center, which was judged to be due to the thick skin of the seedless watermelon.

-Quantity according to the type of fruit cover

z DMRT(0.05)

· Product rate was higher at 96% in the non-woven fabric 40g and 50g/m² treatment group compared to 90% in the newspaper control group, and the product quantity was also 4,838～5,184kg/10a, so there was significance between treatments.

In Fig. 4, the degree of damage by treatment division is shown in %.

In addition, there is also an effect of preventing the occurrence of pests as described in the following table. Except for the case of using the nonwoven fabric of the present invention and the case of using newspaper, pests such as cotton monarch moth or pabam moth occurred. In addition, it can be confirmed from the table that watermelons and the like occurred in all cases except for the case of using rice straw and the nonwoven fabric of the present invention.
