Grapes are well bagged and the price can be as high as 50%
Grape bagging is currently an important technology for producing high-quality and high-end fruits. After bagging, the color of the ears is bright, smooth and pollution-free, which greatly improves the market competitiveness. The market price of bagged grapes is 20%-50% higher than that of unbagged grapes.
Purpose of bagging: bagging grapes can reduce pests, diseases and birds during fruit growth, reduce sunburn, reduce pesticide and dust pollution, and improve fruit surface finish; improve the micro-environment of fruit growth, make the fruit evenly colored, brightly colored, and peel Delicate, improve fruit quality.
Bagging selection: According to the influence of microenvironment on the appearance and internal quality of the fruit, paper bags with strong wind and rain resistance, good air permeability, high light transmittance, high hydrophobicity, and anti-bacterial characteristics should be selected according to the variety. Fruit bags made of newspapers have poor hydrophobicity, poor tensile strength, and high breakage rate, and are prone to fruit diseases; non-woven fabrics have good air permeability but are prone to sunburn. At present, the special grape bags combined with plastic film and special paper are the most advanced ones, which can be used for the production of different requirements.
Bagging time: The time of bagging will also directly affect the effect of bagging. Early cover is not conducive to fruit thinning, and late cover will damage the ears. If bagging is too late, the ears will easily be infected with pathogens in mid-June, especially It is white rot, anthracnose, acid rot, gray mold and so on. Generally, bagging is carried out 15-20 days after the fruit is set, that is, when the fruit grows to the size of a bean, it will be bagged immediately after the grain is thinned and the ear is whole. After the rainy weather is sunny suddenly, do not put on the bag immediately, because it will make the sunburn worse. After a day or two, the fruit is slightly adapted to the high temperature environment before bagging. The bagging time****** is before 10 am or after 4 pm, which can reduce sunburn. For varieties that are prone to air burn, such as sunshine rose, sapphire, etc., bagging should be carried out after the hard core period, so as not to aggravate air burn due to premature bagging.
Debagging: After debagging and before harvesting, the main purpose is to color the berries. In the case of insufficient sunlight and poor color, the paper bags must be removed 2-3 weeks before harvest to improve the coloring effect (cyan grapes do not need to be bagged). After removing the bag, turn the ears once or twice according to the ear condition to make the fruit kernels and bunches evenly colored.
