Coffee beans structure text baking machine structure diagram

Select fully ripe, normally shaped, plump, uniform in size, two-seeded fruits from coffee seed trees. Remove the peel of the selected fruit, the operation must be careful to prevent damage to the seeds and affect the germination rate, and then put the peeled seeds in a ventilated and cool place to dry, the seeds can be stored after the shell turns white, do not expose the seeds, put the seeds into bamboo baskets or cloth bags, turn over the sun once a month, so that the long-stored seeds maintain a high germination rate. Coffee seedling stage needs shade conditions, so seedling sites should be selected in shady slopes and loose, fertile sandy soil with certain shade conditions and water sources. Adopt general seedling preparation method, dig loose soil into seedbed leveling can be sown. According to sowing 1 kg seed, need 1.5 square meters seedbed, each kg seed about 3500-4000, emergence rate above 80%, can transfer seedlings 2500-3000, before sowing can be soaked in warm water 40℃ for 12 hours, the best effect

Bud grafting method: using one-year-old seedlings, cleaning the soil at the base of stems, then opening a bud grafting position of 2.5-3.5 cm in length, selecting fully developed nodes from excellent mother trees or propagation nurseries, cutting buds with a small amount of xylem, placing them in bud grafting positions, tying them with binding bands, opening bud points after 20 days, healing bud opening interfaces after 30-40 days, completely untying, cutting rootstocks from surviving seedlings after 5 days, and re-budding those that do not survive.

Splitting: Annual seedlings are used as rootstock, when the rootstock is split, the rootstock is cut at a position 10- 15cm away from the ground, a cut with a length of 3- 5cm is vertically cut in the middle of the cut, a straight branch consistent with the size of the rootstock is selected, the cut is cut at a position 3- 4cm below the node, the scion base is cut into a wedge shape, the scion is inserted into the cut of the rootstock, attention is paid to aligning the cambium layer, and the scion is tightly bound by a binding belt, in order to improve the survival rate, the scion can be wrapped by the binding belt, and the scion is arranged at the rear budding point at 20 DEG C, The growth and development of 30-40 days coffee is closely related to climatic conditions. In the areas with strong wind, high temperature, strong light and easy drought soil, axillary buds tend to differentiate into flower buds, and the growth of branches is small, which is easy to cause premature senescence. Therefore, to choose quiet wind, humidity, light shorter place for garden. Arabica coffee is a plant that needs water and is afraid of too much water. Where the rainfall is below 1400 mm, irrigation conditions or water conservancy facilities should be selected. The good gas of coffee roots is very strong. The soil drainage is poor. Drainage should be added. Soil sediment content is large, water retention fertility is poor, to use mulch, increase the application of organic fertilizer. Sloping land should be changed into terraced land before it is suitable for planting. Dig planting holes 2-3 months before planting, separate topsoil and subsoil when digging ditches, return topsoil to ditches, apply 100kg calcium magnesium phosphate fertilizer per mu, apply 2- 5kg soil miscellaneous fertilizer as base fertilizer where conditions permit, fill trenches with topsoil (mix topsoil and base fertilizer evenly) about 15 days before planting, so as to avoid soil subsidence after planting and affect survival.

Generally speaking, sour coffee beans, especially high-quality new beans, the best degree of baking lighter, and bitter system is the degree of baking lighter, and then sweet details are mostly high-real estate washing selected beans, baking often constitutes whether it can be integrated into the soft bitterness, the key to be tasted. Neutral flavor, even if it is not high-quality coffee beans, also have to have stable quality of stability treatment. Coffee beans with aromatic and mellow effects.
