Insect-preventing and disease-preventing seedling raising device for improved variety of clonal tea trees

Abstract

The invention discloses an insect-preventing and disease-preventing seedling raising device for an improved variety of clonal tea trees. The insect-preventing and disease-preventing seedling raising device comprises a top seat, two seedling raising groups are arranged at the lower end of the top seat in a bilateral symmetry manner, each seedling raising group comprises a plurality of seedling raising boxes which are sequentially arranged from bottom to top, and the front side and the rear side of each seedling raising group are rotationally connected with a main connecting batten and an auxiliary connecting batten which are parallel to each other; transparent films are connected between the main connecting battens and the auxiliary connecting battens, each main connecting batten is connected with a transparent baffle, and a transparent extending plate is upwards arranged at the side, away from the symmetry plane, of each seedling raising box; and a first water leakage hole is formed in the bottom of each seedling raising box, a seedling raising pot capable of being detached and taken out is arranged in each seedling raising box, a second water leakage hole is formed in the bottom of each seedling raising tray, the seedling raising tray capable of being detached and taken out is arranged in each seedling raising pot, and each seedling raising tray is provided with a plurality of seedling raising cup sleeves with two open ends. By means of the insect-preventing and disease-preventing seedling raising device, sealed seedling raising can be carried out on cut cuttings, and ventilation cultivation of tea seedlings in the later period is facilitated.

Description

technical field [0001] The invention relates to the technical field of tea tree seedling cultivation, in particular to a device for cultivating seedlings of improved clone tea tree varieties for preventing insects and diseases. Background technique [0002] There are two main propagation methods for tea trees, one is seed propagation, and the other is cutting propagation by cuttings. Compared with seed propagation, the cutting propagation of spikes can maintain the inherent characteristics of tea tree varieties. The growth period and growth potential of the offspring are consistent, and the size, tenderness, and color of new shoots are closer. It is convenient for mechanized tea picking and the standardization of the primary production process. It has the advantages of improving quality, saving labor, increasing production, etc. Therefore, cuttings of spikes are currently the main way for tea tree propagation. At present, the main method of cutting and propagating tea tree ...

AI Technical Summary

Problems solved by technology

At present, the main method of cutting and propagating tea tree spikes is short spike cutting, that is, a complete tea tree branch is cut upwards from the bottom to a short stem with an axillary bud and a complete healthy leaf, which is 3 to 4 cm long. Cut it directly in the soil or in the cutting cup, pull it out when transplanting in the second year, and move it to the plot to be planted. It is difficult to prevent pests and diseases in the soil by directly growing seedlings in the soil. Generally, the cutting cups are placed in the seedling bed. Some seedbeds have simple structures and single functions, and have no effect of insect and disease prevention.
