The field management measures are suitable for the management of general small-grain coffee. Propagation method: adopt seed propagation, select 5-year-old fine mother tree, harvest fully mature, fruit shape is normal, full, size is basically the same, with two-seed fruit as seed, using sand bed to promote germination, plastic bag seedling.

Selection of suitable forest land

The annual mean temperature is 19-21 ℃ years, the accumulated temperature of annual ≥ 10 ℃ is more than 6800 ℃, the coldest monthly mean temperature is more than 11.5 ℃, the absolute lowest temperature is above 1 ℃, the coldest monthly mean temperature is ≥ 11.5 ℃, the monthly mean temperature of ≤ 13 ℃ is more than two months, the extremely lowest general year is more than 0 ℃, and some years appear areas of-1 ℃ or short-2 ℃. The annual rainfall is ≥ 1100mm below 1200m above sea level, and the soil should be fertile loam, loose soil, good drainage, PH value 66.5and slope less than 25 °, so as to avoid planting in the depression where cold air is easy to deposit.

Forest land reclamation

Coffee is a long-term economic crop, woodland reclamation must be long-term planning, good planning, before reclamation must do a good job of road, shed, fertilizer pool design. When reclaiming woodland, shade trees should be selected to make the coffee woodland after planting have 30% shade, and then adjust to 20%. In planning and design, we must do a good job in the planning and reclamation of horizontal terraces and terraces, which is not only the primary task of soil and water conservation, but also an important work to bring convenience to field management after planting. Trenching, with the specification of upper mouth width × depth × bottom width 60 × 50 × 40cm, will be reclaimed before the end of November to the end of March of the following year.

Coffee trees in Arabica are not easy to grow, many are on high-altitude slopes, and picking needs to be done manually. But it is better to have a balanced taste and less caffeine. And Robasta is relatively easy to grow, a variety of heat-resistant, cold-resistant, moisture-resistant, drought-resistant, disease-resistant. Once upon a time, coffee in Vietnam was planted by Robasta because of leaf rust and all the coffee trees planted in Arabica died. In addition, Rothbata is also relatively easy to harvest, in addition to manual vibration machines can also be competent. This variety has all kinds of benefits, but what is fatal is that the coffee beans produced are poor in aroma, lack of bitterness, lack of acidity, and high caffeine content, so they are mostly used to make instant coffee. Now most of the beans on the market are grown in Arabica.

Coffee is a short-day plant. Coffee has the characteristics of multiple flowering and concentrated florescence. The florescence of small seed coffee in Yunnan is from February to July, and the flowering period is from March to May. The flowering of coffee is greatly affected by climate, especially rainfall and temperature. Coffee flowers have a short life span of only 2-3 days. Small seed coffee usually opens at 3: 5 in the morning and blooms from 5 to 7 o'clock.
