Introduction to the planting requirements of natural weather for the yield of coffee trees

"to come to Xinglong is to try the authentic Xinglong coffee." On May 1, Yang Huining, a tourist from Heilongjiang, specially went to Xinglong to taste "the coffee praised by Premier Zhou."

Dong Yunping, associate researcher of the Chinese Academy of Tropical Agricultural Sciences and director of the Coffee Research Center, told reporters that with the continuous warming of tourism in Hainan in recent years, our province has gradually become the region with the strongest coffee culture and one of the largest coffee consumption markets in China, with annual sales of dried coffee beans reaching 6000 tons.

Embarrassing for Hainan, despite its reputation, the actual output of local coffee beans in Hainan is very small. "at present, the annual output of dried coffee beans in our province is only about 200 tons, mainly in Xinglong and Fushan. Even with the newly planted coffee trees in the past two years, the total area of coffee trees in the province is only about 10,000 mu. At present, there are only about 2000 mu of coffee trees hanging fruit. Even if calculated according to the annual output of 100 kilograms per mu, it is far from meeting the market demand for coffee in Hainan. " Dong Yunping said that all kinds of coffee beans imported from abroad but under the banner of "Hainan Coffee" fill the demand gap.

Dong Yunping's claim is supported by a forecast of tropical crops for 2013 from the provincial agriculture department. The table shows that in 2013, the planting area of coffee trees in Hainan is 6000 mu, and the total output of dried coffee beans is expected to be 200t.

Many people in the industry also told reporters that Hainan's coffee is now on the verge of drying up its production source. Most of the products on the market under the banner of "authentic Hainan coffee" are processed with coffee beans from Vietnam and Yunnan. "Hainan imports about 3000 tons of coffee beans from Yunnan every year, and also imports two to three thousand tons of coffee beans from Vietnam, Brazil and other places."

Take "Xinglong Coffee" as an example, according to incomplete statistics, there are nearly 10 enterprises in Xinglong Town alone, of which 5 are of a certain scale, while there are several enterprises outside Wanning City. Only based on the production capacity of five large-scale enterprises in Xinglong Town, if all local coffee beans are used, the annual demand will be at least 1000 tons, equivalent to 10, 000 mu of planting area. If you add in the enterprises outside Wanning, you need at least 2000 tons of dried coffee beans, which is equivalent to the output of 15000-20 million mu of coffee trees.

However, the reporter's field investigation found that the planting area of coffee trees in Wanning City is only about 2500 mu, of which 2000 mu are newly planted year by year after 2009. On the other hand, it takes three years for coffee trees to begin to bear fruit and five years to reach a high yield period.

There is no difference in yield between north-south and east-west coffee trees. This is the orange fruit obtained by the Coffee Institute of Chulvado in a test lung. The trial material is a rejuvenated coffee tree. It is said that the coffee trees that plant in the east-west direction seem to grow more vigorously than those in the north-south direction six months after they are cut off and pull out new branches, but by the second apple, this advantage has disappeared. When they were young, the plant growth in the north-south direction was poor at first because it was sheltered by the nearby unpruned coffee trees, resulting in less exposure. In the same study, the effects of the number of direct dried stems on coffee yield were also compared. It was observed that the plants with 3-5 channels of dust drying were indeed higher than those of plantations with only 1 or 2 tracks. The planting distance of the second area is 3 x 3 Yan and the algal shielding degree is 5. One 60%. All treatments were treated with 1 pound of 13-13-13 formula fertilizer per year. (Direetion of Coffee Rows Ha. O Influenee on Yield,' Coffee Aud Ca- ca . Journal ", Vol.6, plus 9 department Nov., 1963. Zhan Shu skirt choice) the direction of coffee tree planting has no effect on the yield of coffee trees planted in the north-south direction and east-west direction, there is no difference in yield. This is Zelva.
