Abstract

The invention discloses a soilless culture substrate capable of self water absorption and conglobation. The soilless culture substrate comprises the following raw materials in parts by weight: 15.0-60.0% of azobamidoamine, 10.0-15.0% of phenolics, 2.0-6.0% of azodiisobutyronitrile, 8.0-15.0% of sodium bicarbonate, 5.0-6.0% of isocyanate, 1.0-3.0% of hydroxyl, 8.0-15.0% of carbon dioxide, 1.0-6.0%of polyurethane, 3.0-6.0% of polystyrene, 3.0-6.0% of turf soil, 4.0-8.0% of cotton cloth, 2.0-5.0% of sphagna; 1.0-3.0% of vermiculite, 1.0-4.0% of perlite, and 2.0-4.0% of carbon particles. The soilless culture substrate capable of self water adsorption and conglobation ensures that the root systems of the plants are on the substrate during the seedling breeding and potted plant transplantation,the root systems of the plants cannot be damaged during the transplantation, the survival and the growth of the plants are facilitated, and the blockage caused by the fact that the substrate is not agglomerated easily and is easily scattered in the virtuous cyclic production of a water system is greatly reduced. When the substrate provided by the invention is used for irrigation and fertilization, the water circulation system is not blocked, the effect of the water absorption of the substrate is more obvious, the growth uniformity of the plants is improved, and the workload is reduced.

Description

Technical field [0001] The invention relates to the field of soilless culture technology substrates, in particular to a soilless culture substrate that can autonomously absorb water and form clumps. Background technique [0002] Soilless cultivation uses light materials such as grass charcoal, forest mulch, and expanded vermiculite as seedling substrates to fix plants, allowing plant roots to directly contact nutrient solution, and adopting mechanized precision seeding and one-time seedling cultivation technology. The selected seedling tray is divided into compartments. One seedling is planted and one seedling grows in one compartment. The root system of the mature seedling and the substrate are entangled with each other. The root tuft is in the shape of a plug with a large upper and a small bottom. Nursery. [0003] At present, the traditional soilless culture substrate, light materials such as grass charcoal or forest mulch, expanded vermiculite and perlite are used as seedling ...
