In the case of better management, the coffee began to bear fruit in the third year after planting. The fertilization of adult coffee fruit trees should be mainly nitrogen and potassium fertilizer, and properly combined with phosphorus fertilizer and other elements. The effect of applying potash fertilizer from July to August is the best. Fruit trees are generally fertilized five times a year, once in February to March (flowering stage), April to May (young fruit stage), July to September (fruit filling period), October to November and December to January of the following year. The annual application of organic fertilizer or compost is 1520kg, urea 250g 500g, calcium superphosphate 150g 500g, superphosphate 150g 250g, potassium chloride 150g 200g

The establishment of ① multiplication nursery requires a large number of direct branches and bud slices as materials for cutting and bud grafting. In order to speed up propagation, multiplication nurseries are established. The auxiliary planting density of proliferating seedlings was 1.5 m × 1 m, which was planted according to different clones.

Preparation of ② cutting materials straight branches are used in cutting materials, not a branch, because the new plants grown after cutting with one branch can only grow creeping, not straight coffee trees.

Cuttings should be cut with green uncorked, fully aged leaves, robust straight terminal buds to the lower 2-3 segments, not semi-corked and corked straight branches. The blade of the cuttings is 4 inches wide (about 6 inches 8 cm), and each section of cuttings is 4 inches 6 centimeters long. the cuttings are cut into two pieces, each with a blade, and the cut is oblique and smooth.

The preparation of the ③ slotting machine generally uses a sand bed with a thickness of 40 to 50 centimeters, with coarse sand in the lower part and medium fine sand in the upper part, with a shade of 80 to 90 percent. 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.

④ cutting method can cut cuttings obliquely or directly, and the depth of cuttings is buried in the leaf nodes. 10 cm to 15 cm in a row, with the leaves not shielding 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.

The management of ⑤ cuttings is mainly dripping water and disease prevention, which requires higher air humidity and lower temperature in the cutting bed. Do not drench too much water to avoid cuttings rot or disease. In order to prevent the occurrence of diseases, carbendazim can be sprayed immediately after cutting. If there is a disease later, spray it again for 1 or 2 times.

The transplant cuttings of ⑥ rooting cuttings grow to 3 cm and 4 cm about 60 days after cutting. although it is convenient to move seedlings at this time, it is best to transplant when the cuttings grow the second round of lateral roots (about 90 days after cutting), and the survival rate is high. It should be handled carefully when moving seedlings, because the root system is very fragile and fragile.
