Mechanical picking method of fresh fragrant tea leaf raw material in high-slope tea garden

Abstract

The invention discloses a mechanical picking method of a fresh fragrant tea leaf raw material in a high-slope tea garden.In spring in the same year, a few bud leaves with germinated and protruded bush faces are manually picked to make a mechanical spring tea picking face more orderly; the one-bud three-leaf proportion of tea tree shoots is up to 30%, and a single backpack type tea-leaf picker is selected for fresh leaf picking; during mechanical picking, one main picker operator and one assistant are arranged, a shear mouth of a blade of the tea-leaf picker is upwards 1 to 2 cm away from the base parts of the shoots, and in the advancing process of mechanical picking, the main picker operator controls the direction and speed for parallel advancing, one-time half-edge picking and two-time reciprocated picking operations are adopted for each tea bush, and the assistant turns over and unloads tea leaves in a tea leaf collecting bag in time; by applying variety optimization, crown transformation and bush face cultivation, mechanical picking suitable period determination, mechanical picking machine selection and other matched mechanical picking technical measures, the highest integrity rates of mechanically picked fresh leaf buds of high-slope Longjing tea 43 and Yingshuang tea can be up to 84.27% and 80.18% respectively.

Description

technical field [0001] The invention belongs to the field of tea picking methods, and in particular relates to a mechanical picking method for fresh fragrant tea leaves in tea gardens on high slopes. Background technique [0002] At present, the shortage of labor force has become a key limiting factor hindering the development of the tea industry. Among them, the shortage of tea picking workers is more prominent. We can only strengthen the research on tea machine picking, vigorously promote the technology of tea machine picking, and realize the mechanized picking of fresh tea leaves as soon as possible. Only in this way can we fundamentally solve the stubborn problem of labor difficulty in picking tea. At the same time, machine picking is also an important measure to reduce production costs, stabilize tea quality, and improve economic benefits. [0003] In fact, for a long time, people have recognized the importance of machine-harvested tea, and conducted a series of experim...

Problems solved by technology

This practice often ignores the specific requirements of mechanical harvesting on technical indicators such as crown height and canopy leaf thickness.

3) The grasp of the timing of mechanical harvesting needs to be improved mainly in two aspects. First, the grasp of the timing of mechanical harvesting is usually judged by the naked eye and experience, which has great randomness and volatility, resulting in large differences in the mechanical composition of fresh leaves, and Difficult to obtain optimal fresh leaf quality

Second, at present, it is difficult to unify the definition and control methods of the standards for the suitable period of machine-harvested leaves, which leads to uneven quality of machine-harvested fresh leaves. Correlation evaluation research to determine the new standard for machine harvesting

(4) It is very difficult to harvest tea gardens on slopes in mountainous areas. In addition to the above technical bottlenecks, tea gardens on slopes in mountainous areas are affected by many unfavorable factors such as terrain restrictions, low temperature, frequent wind and freezing, difficult to absorb and easy loss of nutrients, and other unfavorable factors. The growing trend is relatively weak, and the agricultural operations in slope tea gardens are inconvenient, so it is more difficult to carry out mechanical picking of fresh tea leaves, and it is urgent to follow up relevant cultivation supporting technologies in time
