Embodiment Construction

[0017] In order to illustrate the technical solution of the present invention more clearly, a detailed description will be made below in conjunction with embodiments.

[0018] The embodiment of the present invention provides an application of a bio-based sulfonate as a water retention agent and a sustained release agent to prepare a seedling cultivation plug 10 . The composition of bio-based sulfonate is composed of cellulose sulfate monoester salt, hemicellulose sulfate monoester salt and lignosulfonate. In the embodiment of the present invention, the biosulfonate is obtained through the following steps:

[0019] Step S101, preparing sulfur trioxide / 1,2-dichloroethane solution: dissolving sulfur trioxide gas, liquid or solid in the aprotic solvent 1,2-dichloroethane under cooling conditions to form Sulfur trioxide / 1,2-dichloroethane solution.

[0020] Step S102, preparing cellulose powder: crushing cellulose-rich plant fibers to 50-300 mesh, drying at 100-140°C to become ce...

Abstract

The invention provides an application of bio-based sulfonate as a water-retaining agent and a slow-release inhibitor in preparation of a seedling hole tray. The bio-based sulfonate is prepared from cellulose sulfate monoester salt, hemicellulose sulfate monoester salt and lignosulfonate. The invention further provides the seedling hole tray prepared from the bio-based sulfonate. The seedling hole tray prepared from the bio-based sulfonate comprises paper pulp and the bio-based sulfonate, wherein the mass of the bio-based sulfonate accounts for 10-15% of total mass of the seedling hole tray.

Description

technical field [0001] The invention relates to the technical field of agricultural production, in particular to the application of a bio-based sulfonate as a water-retaining agent and a slow-release agent to prepare seedling-raising plugs and the seedling-raising plugs. Background technique [0002] At present, seedling trays have become an important tool in the industrialized seedling production process. Common plastic trays are mostly used in vegetable seedling cultivation and melon and fruit grafting rootstock seedling cultivation processes. Ordinary plastic trays are usually molded from plastic materials such as expanded polystyrene or polyethylene or processed from hard plastics. Plastic trays are expensive to manufacture and are generally disposable. Waste plastic trays are difficult to degrade, which can easily cause soil and surrounding environment pollution. Long-term storage will also produce dioxins and other harmful chemicals. Ordinary plastic trays have stron...
