Kumquat is a fruit in late autumn and early winter, and it ripens in the middle and late of 10 every year. Pick it before the first rain in 1 1 month at the latest, otherwise, the fruit will rot if left on the tree for a long time. The sales season of kumquat is from winter to around, from New Year's Day to the eve of Spring Festival every year.

Kumquat is widely distributed in the southern foot of Qinling Mountains and the Yangtze River basin.

In recent years, the rapid rise of labor price has promoted the rapid increase of kumquat production cost. The production of kumquat requires a lot of labor, especially pruning, erecting plastic film and picking fruits.

Extended data:

Cultivation of kumquat:

1, sprouting period of spring shoots (March), draining some spring shoots in that year. At the tender shoot stage, 0.3%~0.5% urea and 0. 1% borax can be sprayed.

2. It is best to spray nutrient solution (0.2% borax and 0.2% potassium dihydrogen phosphate) at the end of June to mid-July, 1 young fruit stage and 2/3 secondary flowering stage, which can cooperate with pest control to protect fruit. Keep one fruit and two fruits at intervals of 1 fruit-keeping 15~20 days, and the formula can be the same as 1 fruit-keeping.

3. Erase all summer shoots in the budding period (from June to the end of July) to control the occurrence of scab and anthracnose.

4. During the fruit expansion period (from July to 65438+ 10), the fruit is easy to crack, so the anti-cracking agent should be used to spray the fruit to prevent cracking and protect the fruit, and the prevention and control of red spider, rust and black spot should be strengthened.

5. When the fruit matures (165438+ 10 month), prevent the fruit from falling before harvest, mainly control scab, anthracnose and black spot, trap and kill pests with black light or poison bait, spray pesticides to drive away pests, and spray biological pesticides to control diseases.
