Description of Coffee Flavor of Katim Coffee in Yunnan Province, China

Introduction to the method of describing the Flavor of Coffee beans from Katim, Yunnan, China

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.

Apply sufficient base fertilizer

3000-4000kg high quality organic fertilizer per mu, phosphate fertilizer 80-120kg returned to the hole 15 days before planting (organic fertilizer, phosphate fertilizer and soil were mixed well and applied into the planting ditch).

Strong seedling planting

Select seedlings with robust growth, close to branches or 3 pairs of branches, stout main stem, stem diameter above 0.4cm, and no curved root. The irrigated land can be planted in advance (February-March), and the planting row spacing depends on the topographic environment, usually planting 330mi 420 plants per mu.

Water and fertilizer management

This variety is a variety with high and stable yield. The results of trial planting in different ecological areas show that as long as it is planted in accordance with high-yield cultivation techniques, a higher yield will be obtained, with an average yield of more than 150 kg per mu and a small area of more than 400 kg.

1. The state-run Lujiang Farm in Baoshan City planted 12.6 mu in March 1991. The land is unshaded and irrigated once in the dry season. The level of management and fertilization is above. In 1993, the average yield per mu was 75 kg in 1993, 350 kg in 1994, 225 kg in 1995, 217 kg in 1996, and 36% higher than Tiebika and Bobang (160 kg per mu).

2. Yunnan Dehong Tropical Agricultural Science Research Institute 1991 planted 30 mu with no shade and anhydrous irrigation, with a medium level of fertilization and management. the average yield per mu was 304.3 kg in 1993, 294 kg in 1994, 222.5 kg per mu in 1995, 273.6 kg per mu in 1995 and 1996, and 82% higher than that of S288 (S288).

3. The covered field coffee base of Ning'er County Coffee Company planted 50 mu in July 1998. the site environment was unshaded, the level of management was medium, and the level of fertilization was low, but the soil fertility was high. Since 2000, the average yield per mu was 285kg in 2001,2002,340kg in 2002,293kg per mu in 2003,306kg per mu in three years, 53% higher than PT and 91% higher than P4 (PT). P4 average yield per mu is 160 kg)
