Flavor description of Katim Coffee beans introduction of regional varieties produced by grinding scale treatment

Field management measures are applicable to the management methods of general Arabica coffee. Propagation method: seed propagation is adopted, 5-year-old excellent mother trees are selected, fully mature fruits with normal fruit shape, plump fruit shape and basically consistent size and two seeds are adopted as seeds, germination is adopted in sand beds, and seedlings are raised in plastic bags.

Selection of suitable forest land

The annual average temperature is 19~21℃, the accumulated temperature of ≥10℃ is greater than 6800℃, the average temperature of the coldest month is>11.5℃, the absolute minimum temperature is above 1℃, the average temperature of the coldest month is ≥ 11.5 ℃, the month with average monthly temperature ≤13℃ is more than two months, the extreme minimum year is above 0℃, and the area with-1℃ or temporary-2℃ appears in some years. Below 1200m above sea level, annual rainfall ≥ 1100mm ; fertile loam soil is better, loose soil, good drainage, PH value 6~6.5, slope less than 25° sunny slope gentle slope land, terrace planting, avoid planting in cold air easy to deposit concave land.

forest land reclamation

Coffee is a long-term cash crop. Woodland reclamation must be planned from a long-term perspective. Roads, sheds and fertilizer pools must be designed before reclamation. When forest land is reclaimed, shade trees should be reserved, so that 30-40% of coffee forest land after planting will be shaded, and then adjusted to 20-30%. In planning and design, planning and reclamation of horizontal terraced fields must be done well. This is the primary work of soil and water conservation, and it is also an important work to bring convenience to field management after planting. Trenching and trenching, with the specification of upper opening width × depth × bottom width 60×50×40cm, is cultivated from November to the end of March of the following year.

apply sufficient base fertilizer

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

seedling planting

The seedlings with strong vigor, close to branches or 3 pairs of branches, strong main stem, stem diameter of more than 0.4cm and no bent roots were selected for planting. For irrigated land, early planting (February to March) can be carried out, and the planting spacing depends on the terrain environment. Usually, 330-420 plants are planted per mu.

The results of trial planting in different ecological areas showed that if the high yield cultivation techniques were followed, higher yield would be obtained. The average yield per mu was more than 150 kg, and the small area could reach more than 400 kg.

1. The state-owned Lujiang Farm in Baoshan City was planted in March 1991 with an area of 12.6 mu. There was no shade and irrigation once in dry season. The level of management and fertilization was medium. The fruit was produced in 1993. The average yield per mu in 1993/94 was 75 kg. In 1994/95, the average yield per mu was 350 kg. In 1995/96, the average yield per mu was 225 kg. The average yield per mu in three years was 217 kg. The yield was 36% higher than that of Tibika and Bobang.(The average yield per mu of Tibika and Bobang is 160 kg).

2. Dehong Institute of Tropical Agricultural Sciences, Yunnan Province, planted 30 mu in 1991, irrigated without shade and water, with medium fertilization and management level. The average yield per mu in 93/94 was 304.3 kg, 294 kg in 94/95, 222.5 kg in 1995/96, and 273.6 kg per mu in three years. The yield was 82% higher than that of S288 (S288 average yield per mu was 150 kg).

3. Ninger County Coffee Company planted 50 mu coffee base in July 1998. The site environment was not shaded, the management level was medium, the fertilizer level was low, but the soil fertility was high. The fruit began to bear in 2000. The average yield per mu in 2001/2002 was 285 kg, the average yield per mu in 2002/2003 was 340 kg, the average yield per mu in 2003/2004 was 293 kg, and the average yield per mu in three years was 306 kg. The yield is 53% higher than PT and 91% higher than P4 (PT average yield is 200 kg/mu, P4 average yield is 160 kg/mu)
