What role does the kumquat film play in the kumquat planting process?

The Guangdong-Guangdong region is a famous kumquat planting place in China. It is known as the hometown of kumquats. Because kumquats are sunny and warm and humid, and they are not cold-resistant, it is necessary to use kumquat film for heat preservation in kumquat cultivation. Protection, then what role does the kumquat film play in the cultivation of kumquat?
First, it can effectively reduce low temperature freezing damage. The special orange film is added with special heat preservation agent. When the sunlight rises, the temperature inside the film is high and the water vapor is large. The nighttime heat retaining agent plays the role of retaining heat, ensuring a warm and humid growth environment inside the film.
Second, it can increase the sugar content of kumquat. The temperature difference between day and night affects the accumulation of sugar in the fruit. During the ripening of kumquat, the use of kumquat membrane cultivation can effectively accumulate temperature, which is conducive to the accumulation of sugar and the improvement of fruit.
Third, it can reduce the fruit drop of kumquat. The environment of high temperature and high humidity in the air is prone to cause diseases and cause citrus floating. The kumquat film has a great influence on the yield of staying trees. The average fruit drop rate of the fruit trees in the cover film is more than 30% lower than that of the uncoated fruit. After covering the membrane, the tree does not directly contact the rainwater, and does not affect the juice content of the kumquat fruit. Guangdong and Guangxi are wet and rainy in winter, and the natural conditions are not conducive to the preservation of kumquats, and the loss of fruits and fruit is relatively large. In the beginning of December, the average grower will simply cover the tree that needs to keep the tree fresh, so that the fruit trees can avoid the rain and keep warm. The harvesting period is about 45 days after the film is covered, which is about 5 days after the Great Cold. At this time, the spring festival is generally 10 to 20 days, and the indicators of fruit quality are relatively good.
The cover film method used in the kumquat film is generally: a method of covering a single compartment or a double compartment, covering the shelf cover or directly covering it. Cover the single compartment with a 4 m or 5 m membrane and cover the double compartment with a 7 m or 8 m membrane. Before the cover film should be supplemented with nutrition, add fungicides, pay attention to insecticide and bird repellent.
Fourth, effectively reduce the rate of fruit rot.
Nowadays, it is the season when the kumquat film is used in a large amount. The kumquat film produced by Luyi Plastic Factory is of high quality and low price, and the supply is sufficient. Users who need it are welcome to purchase it.
