Seedling raising and planting method of black tea

Abstract

The invention discloses a seedling raising and planting method of black tea, and relates to the field of tea tree planting, and the method comprises the following steps: step one, seed selection; steptwo, constructing a seedling bed with a seedling raising tray; step three, filling fertilizer; step four, cutting branches; step five, unfolding grass curtain to block seedling-raising box; step six,covering grass curtain; step seven, transplanting seedling-raising box; after the tea seedlings grow three or four leaves, each seedling-raising box is removed from the seedling raising tray and is transplanted into the dig planting pit together with the branches thereof. The dig planting pit is filled with soil until the fixing frame is completely buried, and only the irrigation mouth and the grass curtain are left on the ground. The seedling raising and planting method of black tea has the advantages of reducing manual operation and raising the survival rate of seedling.

Description

technical field [0001] The invention relates to the field of tea tree planting, in particular to a method for growing black tea seedlings. Background technique [0002] Black tea is one of the six basic tea types and has a large number of drinkers all over the world. Due to the separation of traits in the direct sowing of tea tree seeds, it is easy to cause species degradation, which leads to difficult management, unstable tea quality and yield, and is not conducive to mechanized operations. Therefore, black tea is now grown by cuttings. [0003] For example, the patent document ZL201410176269 discloses a method for asexual cutting of tea tree seedlings, which includes the following steps: (1) selection and keeping the newly issued branches of tea tree in spring until midsummer, after the semi-lignification of tea tree branches, press The length of each 6cm-7cm is cut obliquely, and only one leaf is left on one branch. The distance between the petiole and the upper end is 0...

AI Technical Summary

Problems solved by technology

Compared with directly sowing seedlings, although cutting seedlings can ensure the quality and yield of tea leaves, the tea trees produced by them are weaker in resistance, and are afraid of dryness, sun exposure, freezing, and weeds. Within one or two years, we must grasp various tasks such as weeding and seedling conservation, shallow plowing and water conservation, timely topdressing, shading, irrigation, and cold protection.

However, when transplanting cutting tea seedlings, whether it is fertilization, shading, irrigation or cold protection, it is basically a manual operation, which not only increases the workload of the workers, but also makes each worker's operation ability and experience different. different, so that the growth of tea trees depends heavily on individuals, and the quality of tea is also affected by the specific operations of workers, which hinders the expansion of tea plantation scale.

In addition, when carrying out various tasks, different tools and devices need to be used, and the cost investment is large.
