7results about How to "Improve seedling quality" patented technology

The present application belongs to the technical field of plant induced regeneration, and particularly relates to a high-efficiency artificial propagation method of Dendrobium candidum, comprising the following steps: taking two-year-old stem segments with nodes as materials, cutting the stem segments into appropriate sizes, and disinfecting the stem segments; and culturing the stem segments in a culture medium A for 90 days, and then completing the proliferation and rooting integration through a direct organogenesis route. The present application realizes the cyclic production of Dendrobium candidum, and the whole culture process can be completed only by using one culture medium, greatly improving the artificial in-vitro propagation efficiency, and the proliferation coefficient is completely comparable to the seed asymbiotic germination method, and the problems of large offspring trait separation and different qualities caused by the seed asymbiotic germination are solved, and the quality and yield of seedlings are greatly improved. The present application can provide a brand-new technical support for the factory-scale growth of Dendrobium candidum, so as to achieve the purpose of cultivating seedlings with genetic stability and excellent quality to improve the artificial planting efficiency, and the cost is low, the cycle is short, and the quality and survival rate of seedlings are high.

The utility model relates to the technical field of agriculture, and discloses a multifunctional seedling raising plate which comprises a base, supporting rods are fixed to the four corners of the top of the base, two seedling raising plates are arranged between the opposite faces of the supporting rods, water storage frames are fixed to the bottoms of the seedling raising plates, and a water tank is arranged at the top of the base. According to the multifunctional seedling raising disc, a filter plate is put into a filter box, a pull plate is pulled outwards to drive a fixing column to leave the interior of a fixing groove, a connecting rod is pulled to drive a special-shaped block to move, the special-shaped block drives a transverse plate to move in the direction of a connecting block, and in the process, the transverse plate enters the interior of a fixing block, so that connection is completed; the redundant water of the seedling raising tray can flow into the water storage frame and is recycled through the water return pipe, then a filter plate in the filter box is recycled to filter out large-particle impurities in the water, and the recycled water can be conveyed into the water tank to be reused conveniently, so that waste of water sources is avoided, and the water-saving effect of seedling raising is improved.

This utility model discloses a convenient corn seedling removal breeding device, belonging to the field of corn cultivation and breeding technology. It includes a culture box with three fixed plates fixedly connected to its inner wall. Each fixed plate has a cultivation plate fixedly connected to its upper surface. Each fixed plate has an air inlet pipe fixedly connected to its inner wall. Each cultivation plate has several sliding push plates slidably connected to its inner wall. The outer surface of each air inlet pipe is fixedly connected to the inner wall of the culture box. This convenient corn seedling removal breeding device, through the installation of an electric push rod, allows the corn seedling to be removed. When the corn seedling needs to be removed, the electric push rod is activated, causing a piston block to slide within the air inlet cylinder. Air is drawn in through a first one-way valve, then through the air inlet pipe and a second one-way valve, filling the cultivation plate with gas. The gas pushes the push plates upwards, allowing the corn seedling to rise smoothly from the cultivation plate. This avoids damage to the seedling roots caused by manual digging or using tools, ensuring the integrity of the root system.

The application relates to a stepped environment-regulating seedling raising device, and relates to the technical field of seedling raising devices. The device comprises a stepped support, a plurality of planting boxes are arranged at the upper end of the stepped support, a plurality of atomizing nozzles arranged in a linear array are fixedly connected to the bottom end of the outer wall of a water pipe, a plant growth lamp is rotationally connected in the rotating seat, two axial flow fans arranged in a mirror image are fixedly connected to the inside of one side of the shell, and an exhaust pipe is fixedly connected to the upper end of the shell. The application has the effects that the plant growth lamp, the atomizing spraying device and the axial flow fan are arranged, the spraying device sprays water mist into the shell through the atomizing nozzles to ensure the stability of humidity by the control device, and the illumination of the plant growth lamp provides sufficient light for seedlings, so that the seedlings can perform sufficient photosynthesis, the environment in the shell can be kept in the conditions suitable for the growth of the seedlings, and the seedling raising efficiency and quality are improved.

The application relates to the technical field of seedling raising, and discloses an oil tea grafting seedling raising device and method, which comprises a support, equidistant ring frames are arranged in the support, seedling raising bags are arranged in the ring frames, and an arrangement assembly for driving the ring frames to be arranged in a stepped manner is arranged on the support. The application can realize the following effects: when weeds in the seedling raising bags are cleaned, the seedling raising bags are arranged in a stepped manner from left to right in a descending order of height, the seedlings in the adjacent seedling raising bags are not staggered, in the subsequent cleaning of the weeds, the seedlings and the weeds in the adjacent seedling raising bags do not interfere with each other, the cleaning operation is facilitated, the seedling raising bags can be arranged while the bottoms of the seedling raising bags are supported, in the subsequent cleaning of the weeds, the bottoms of the seedling raising bags are not damaged, and the weeds can be better cleaned.

The application belongs to the technical field of plant genetic engineering, and discloses a gene for promoting adventitious root development and application thereof. EuWOX11 The application specifically discloses the application of the gene, a recombinant expression vector containing the gene or an engineered bacterium containing the gene in at least one of promoting adventitious root generation, adventitious root elongation, increasing the number of adventitious roots, increasing the biomass of adventitious roots, and promoting the growth of an aboveground part; the application in at least one of improving the rooting characteristics of woody plants, shortening the rooting cycle of cuttage, increasing the rooting rate of cuttage, increasing the survival rate of cuttage, and increasing the efficiency of asexual reproduction; and a method for obtaining a plant with improved adventitious root development. The transgenic plant obtained by overexpressing the gene has a more developed root system, a more vigorous aboveground part, and stronger adaptability after planting, and can significantly improve the seedling raising efficiency and seedling quality and reduce the production cost, and has important application value and economic value in the molecular breeding and industrial breeding of eucommia ulmoides and populus tomentosa.
