First, bagging period
Precocious figs are as big as the thumb in early January and can be bagged. In general Fujian Province and individual areas of Guangdong Province earlier, but if there is frost-frozen areas, you can put early bagging, you can reduce the damage caused by frost damage.
Second, bagging materials
Bagging materials have a great influence on the color and quality of fruits. For example, paper bags made of white paper or newspapers with high transparency have dark red fruits and high sugar content. However, the flesh is harder, the juice is less, and the flavor is poor. In the case of bagging with low transparency, the bag is light red and the fruit is soft. Juicy, good taste, but low sugar, but the cost is too high, the average farmer can not accept. At present, newspaper bags are the most used ones, which are low in cost and good in effectiveness and easy for farmers to accept. Set the newspaper in a rectangular paper bag, 20 centimeters long x 15 centimeters wide, depending on the size of the ear. Since the early maturing variety matured from February to March, but there was no other fruit at that time, the fruit was susceptible to damage by birds, nocturnal moths and bats, so a two-story newspaper bag was used.
Third, bagging method
Before bagging, sparsely remove a part of the fulcrum of the ear that is still too much. Usually, keep 2 to 3 ears in each ear, and then remove the disease, fruit, frostbite or mechanical damage, and then remove the small fruit and fruit. , retain the slightly enlarged fruit in the middle. Trees with strong tree vigor, strong fruiting branches, many leaves, and the middle and lower parts of the crown are appropriate to stay. On the contrary, they are less. After spraying the fruit, a medicine must be sprayed and sprayed with a mixture of bactericidal and insecticidal agents. After spraying, wait for the syrup to dry before bagging. We should follow the principle of taking care from top to bottom and from inside to outside. Do not touch the young fruit with your hands to prevent the formation of fruit rust on the fruit surface. Do not touch the fruit and prevent fruit drop. The bag mouth is fully opened, the bottom of the bag is held by hand, and the young fruit is put into the bag in an appropriate position to prevent the fruit from touching the bag face to reduce sunburn. After the base of the bag is tightened, it is fastened with a nylon thread and can also be clipped with a staple. Each batch of bagging should be marked on the bag, distinguishing the maturity period sooner or later, in order to identify when harvesting. If a paper bag breaks in the middle, it must be promptly replaced. Peel the bag when picking.
