Problems solved by technology

[0003] The commonly used two-person tea picker is directly placed on the top of the tea tree to pick the tea, the effect is not ideal, and the yield of famous and high-quality tea raw materials can be significantly improved when floating on the top of the tea tree, but the number of single pieces is also correspondingly increased.
Some studies use a diamond-shaped plastic net with a side line of 3.5 cm (the width of the side line of the mesh is about 0.1 cm) to cover the tea tree after light pruning and fix it. This method believes that the net can increase the function of filtering old leaves, but this will not only increase the amount of labor virtually. and material costs, and will also have a certain impact on the growth of tea trees. In addition, when picking tea with a tea picker, it is easy to cut the nylon net
At the same time, the two-person tea picking machine needs multiple people to operate together, and the operation intensity is high, and it is easy to pick old leaves and old stems, so it has high requirements on the crown of the tea tree and is not suitable for picking general high-quality tea.
In addition, although the tea picking machine has many advantages over manual tea picking, due to the strong timeliness and short cycle of tea picking, the tea leaves obtained by the tea picking machine are uneven, and subsequent manual classification is required, which increases labor costs.

Embodiment 1

[0039] The present embodiment provides a kind of picking method of the fresh leaf of tealeaves, comprising:

[0040] 1) Carry out the first deep pruning, the second deep pruning and the third deep pruning on the tea tree in the 5th year, the 9th year and the 12th year respectively, and carry out heavy pruning when pruning in the 15th year; Carry out parallel pruning from the middle ten days to the first ten days of November, pruning until the single branch of the tea canopy of the tea tree contains 1~2 mature leaves, light pruning in other periods;

[0041] 2) Fertilize the soil where tea trees are planted: from late September to early November every year, deep ditching is applied, with a depth of 20 cm; 200 kg of rapeseed cake organic fertilizer and 50 kg of potassium sulfate compound fertilizer are applied per mu of soil; Apply nitrogen fertilizer once after mechanized picking, and the nitrogen fertilizer is based on 6kg of pure nitrogen per 100kg of dry tea; make the soil m...

Embodiment 2

[0044] The present embodiment provides a kind of picking method of the fresh leaf of tealeaves, comprising:

[0045] 1) Carry out the first deep pruning, the second deep pruning and the third deep pruning on the tea tree in the 5th year, the 9th year and the 12th year respectively, and carry out heavy pruning when pruning in the 15th year; Carry out parallel pruning from the middle ten days to the first ten days of November, pruning until the single branch of the tea canopy of the tea tree contains 3 mature leaves, light pruning in other periods;

[0046] 2) Fertilize the soil where tea trees are planted: from late September to early November every year, deep fertilization with a ditch depth of 30 cm; 300 kg of rapeseed cake organic fertilizer and 100 kg of potassium sulfate compound fertilizer per mu of soil; Apply nitrogen fertilizer once after mechanized picking, and the nitrogen fertilizer is based on 7kg of pure nitrogen per 100kg of dry tea; make the soil moisture and we...

Embodiment 3

[0049] The steps of this embodiment are the same as those of Embodiment 1, except that the mature leaf filtering device 1 is not installed under the blade of the tea picking machine in this embodiment. Use the standard new shoot ratio that obtains each time in the present embodiment to be 50%-70%, and the standard bud leaf leakage rate is 20%-30%.

Abstract

The invention provides a picking method for fresh tea leaves. The picking method comprises the step that when standard bud leaves reach 60-100 per square foot and account for 50-90% of all the fresh tea leaves, mechanical picking is conducted on tea trees, wherein a tea picker with a mature leaf filtering device is preferably adopted for mechanical picking. By means of the picking method for the fresh tea leaves, mechanical picking is conducted within a specific time, the tea picker for mechanical collection is improved at the same time, the ratio of standard new shoots of mechanically-pickedtea leaves is increased, the miss picking rate is reduced, and processing and production of high-quality tea are facilitated; meanwhile, the labor intensity of tea leaf picking is also reduced, the production cost is reduced, and the sustainable development of tea production is improved.

Description

technical field [0001] The invention relates to the technical field of tea picking, in particular to a method for picking fresh tea leaves. Background technique [0002] In recent years, my country has vigorously developed famous and high-quality tea, and the income of tea farmers has increased significantly. However, because traditional famous and high-quality tea is picked by hand, with the transformation of my country's industry, most of the rural labor force has transferred, and tea picking workers are increasingly in short supply. Mining labor shortage" has become a technical bottleneck restricting the sustainable development of famous tea. By choosing mechanized picking, it can not only improve the waste of resources caused by the shortage of manpower, but also combine with the mechanization of tea processing to further promote the scale and standardization of the tea industry. [0003] The currently commonly used two-person tea picking machine is directly placed on th...
