Cutting materials with straight branches, can not use a branch, because a branch cuttings after the new plant can only grow creeping, can not grow into a straight coffee tree. Cuttings should be cut with green uncorked, fully aged leaves, robust straight terminal buds at the bottom of paragraphs 2-3, not semi-corked and corked straight branches. The leaves of cuttings are four inches wide (about 6-8 cm), and each section of cuttings is 4-6 cm long. The cuttings are cut into two pieces, each with a blade, and the cut is oblique and smooth.

The slotting machine generally uses a sand bed with a thickness of 40-50 cm, with coarse sand in the lower part and medium fine sand in the upper part. The shade degree of the slotting bed should be 80-90%. Wash the sand first when using it, or you can mix it with the coconut bran of 1 stroke 2. Using spray equipment, the rooting rate of cuttings is high, but the cost of equipment purchase is high.

The cuttings can be cut obliquely or directly, and the cutting depth is buried at the leaf node. 10-15 cm in a row, with the leaves not covering each other as the standard. Fully sprinkle with water after insertion to make the cuttings in close contact with the sand. After cutting, plastic film should be covered on the cutting bed to reduce water evaporation and improve the rooting rate of cuttings. When covering the plastic film, it should be arched with iron wire or bamboo, inserted on the edge of the sand bed, and then covered with the plastic film, and then pressed to maintain the humidity in the bed. If spray equipment is used, there is no need to cover plastic film Cymes with several clusters in leaf axils, each inflorescence with 2-5 flowers, without a total pedicel or with a very short total pedicel; flowers fragrant, with pedicels 0.5-1 mm long; bracts basally somewhat connate, dimorphic, of which 2 are broadly triangular, nearly equal in length and width, and the other 2 lanceolate, twice as long as wide, leaf-shaped. Calyx tube tubular, 2.5-3 mm long, calyx limb truncated or 5-denticulate; Corolla white, length varies from breed to breed, generally 10-18 mm long, apically often 5-lobed, rarely 4-or 6-lobed, lobes often longer than Corolla tube, tip often obtuse; anthers protruding from Corolla tube, 6-8 mm long; style 12-14 mm long, stigma 2-lobed, 3-4 mm long

After drinking the original, simple coffee, we approached what is known as the oldest coffee forest in China. At this time, the ancient coffee trees have produced clusters of coffee beans, although they will not mature until next month, but some of them will show bright red. Qi Fenghua said that this forest is considered to be the oldest ancient coffee forest in China. There are 1134 plants in 13 mu, 24 of which have a history of more than 100 years, which were introduced and planted by French missionaries when they built a church in Zhu Kula in 1892. Local Tan Jialin said: "the reason why the 13 mu ancient coffee forest in Zhukula area is listed as the oldest coffee forest in China is that it has 24 ancient coffee trees more than 100 years old, all of which are pure Yunnan small-grain coffee. Its superior quality is very rare. It is the ancestor of Chinese coffee, especially Yunnan small-grain coffee, and has extremely high scientific research value and industrial development value."

Yunnan has a long history of growing coffee and has a unique climate advantage. Yunnan small grain coffee has the characteristics of strong but not bitter, fragrant but not greasy, slightly sour and so on. According to the International Coffee Organization, Yunnan small-grain coffee is similar to Colombian small-grain coffee in quality, and its products are highly competitive in the market. At present, 95% of China's coffee raw materials are produced in Yunnan. Therefore, Yunnan's coffee industry has a far-reaching impact on the development of China's coffee industry.
