Embodiment Construction

[0039] The technical solutions of the present invention will be described in detail by the following examples. The following examples are only exemplary, and can only be used to explain and illustrate the technical solutions of the present invention, but cannot be construed as limitations on the technical solutions of the present invention.

[0040] like Figure 1 to Figure 3 As shown, the present embodiment provides a floating seedling matrix filling scheme and tools used, which mainly include

[0041] Matrix: according to the regulations in YC / T310; Matrix packing principle: uniform, moderate tightness.

[0042] A flat and hygienic site is selected as the loading site, and the substrate is moistened before loading, so that the moisture content of the substrate reaches 30%-40%.

[0043] For standard 162-well seedling trays used in a large number of field plantings, lay a layer of non-woven fabric on the empty floating tray. Then press the non-woven fabric on each hole so th...

Abstract

The invention relates to a floating seedling raising method in fine comparison of tobacco gene editing material strains. Seedling raising holes of a seedling tray are covered with non-woven fabric, and the non-woven fabric can effectively avoid the situation that root systems are damaged due to adhesion of a matrix and the seedling tray (or dispersion of the matrix) during transplanting and seedling pulling, so that the root systems of transplanted tobacco seedlings are kept complete. The non-woven fabric used in the method is a polylactic acid material, can be degraded in soil after being transplanted, is free of harmful degradation product residues after being degraded, and is safe and environmentally friendly. Compared with common field production, the method has the advantages that fine screening of edited materials has higher requirements for uniformity of planting growth vigor, the growth vigor is uniform and neat, errors caused by inconsistent growth and development can be reduced to the greatest extent, and the efficacy of genes is highlighted.

Description

technical field [0001] The invention belongs to the technical field of tobacco floating seedling breeding, and in particular relates to a floating seedling breeding method in the fine comparison of tobacco gene editing material strains. Background technique [0002] Floating seedling is an agricultural planting technology mostly used for green leafy vegetables, tobacco and other plants with short growth period, which can ensure the consistency of plant growth and avoid soil diseases and insect pests caused by traditional cultivation methods. It is widely used in greenhouses all over the world. planting. The use of floating seedlings for plant cultivation and production in greenhouses can bring greater yields, higher quality, and prolong harvest time, limiting and reducing the use of pesticides. Most floating seedling raising techniques are produced by using foamed seedling trays. Soilless culture substrates such as peat and vermiculite are added to the trays. After sowing, ...
