Do You Choose the Right Grape Growing Bag？

The bagging cultivation of grapes has become an important technology to produce high-quality green high-grade fruits. Fruit bag selection is an important part of bagging technology, so how should we choose the right high-quality fruit bag?

1.  Selection of the Fruit Bag Style

1.1  Requirements of Grape Varieties on Light Transmittance of Fruit Bags

• Grapes of Kyoho strain:

The variety does not require high light transmittance of fruit bags, so ordinary wood pulp paper fruit bags can be used.

• Grapes of Eurasian strains:

Because grapes need a lot of direct light when coloring, fruit bags with good light transmittance should be selected.

• Grape varieties with thin skin and difficult coloring:

Fruit bags that can prevent sunburn and easy coloring shall be selected for these varieties.

1.2 Differentiation of Grape Colors

• Green series of grapes, usually in green bags.

• For red, purple and black grapes, light or white fruit bags are preferred.

  
  

  
  

  

1.3 Differences in Cultivation Methods

• Greenhouse planting and rain sheltering planting:

The light intensity is weakened, which will affect the coloring of fruits, but the sunburn is relatively light, so fruit bags with good light transmittance should be selected.

• Grapes planted daily:

Due to sufficient sunlight, sunburn-proof fruit bags should be selected to avoid fruit sunburn.

2.    Quality Inspection of Fruit Bags

• First, soak the grape bag in water. Then, rub the bag back and forth with your hands to check whether it is damaged or softened. If there is damage and softening, it indicates that the bag quality is poor.

  

• In addition, you can look at the transparency of the paper in the sun to see if it is even. If the light transmission is uneven, it indicates that the bag quality is poor.
