Seedling tray for lagerstroemia indica red rocket

Abstract

The invention relates to the field of stock cultivating equipment, and in particular relates to a seedling tray for lagerstroemia indica red rocket. The seedling tray mainly comprises a head cover, an upper plate, a plurality of seedling cavities, upright posts, light sources, a plurality of air supply outlet and a controller, wherein the plurality of seedling cavities are formed in the upper end surface of the upper plate; the upright posts are supported under four corners of the upper plate; one light source is arranged between every two upright posts; the head cover is also arranged at the upper part of the upper plate; the plurality of air supply outlets are also formed in the head cover; the controller is arranged on the edge of the upper plate; the seedling cavities are in a columnar structure; a plurality of bumps are arranged on the inner surfaces of the seedling cavities in a spiral manner; and a plurality of holes are formed in the outer surfaces of the seedling cavities. According to the seedling tray, growth of roots can be promoted by the light sources arranged at the lower part; sunshading can also be achieved through the head cover at the upper part; temperature control on the upper seedlings of the lagerstroemia indica red rocket and control on the lower illumination are achieved by the air supply outlets in the head cover; upper temperature and lower illumination are ensured; and the survival rate of a single plant is improved by air and water permeability of each seedling cavity, so that the overall survival rate is ensured on the whole.

Description

technical field [0001] The invention relates to the field of seedling cultivation equipment, in particular to a seedling raising tray for red rocket crape myrtle. Background technique [0002] Red rocket crape myrtle, a deciduous tree of the genus Lagerstroemia genus Lagerstroemia genus, a new variety of American crape myrtle, the reddest and most beautiful American crape myrtle in the world introduced for the first time from Georgia, USA in 2004 by Hunan Academy of Forestry Sciences relying on the national "948" project A small tree, named for its bright red shoots and blooming flowers.

AI Technical Summary

Problems solved by technology

Cutting propagation is one of the most important propagation methods of Red Rocket Lagerstroemia indica, and in cutting propagation, the requirement for light is not too high when seedlings take root and grow, but the aboveground part needs to assimilate nutrients under light, and Cutting branches, because the branches have leaves, after sunlight, the effect of photosynthesis, can synthesize organic substances to improve root growth, and light can promote plant rooting. The more carbohydrates in the cuttings, the higher the rooting rate, and the strong Light will cause photooxidation of chlorophyll, reduce protein synthesis, and increase carbohydrate synthesis; however, cutting seedlings have extremely low immunity to ultraviolet rays, and too long light time will easily lead to chlorosis of branches and lower survival rate

In the existing seedling trays, only shading is used to ensure the survival rate of seedlings, and there is no equipment to promote the growth of roots, so the survival rate and growth efficiency of seedlings are not high, resulting in large-scale cultivation. The production cycle is long, the success rate of cultivation is low, and the production cost is high
