Abstract

The invention discloses an organic medium special for raising rice by mechanical seedling transplantation and belongs to the technical field of rice culture media. The organic medium is characterized by comprising the following components in percentage by weight: 10 to 30 percent of biomass power plant ash, 20 to 40 percent of monosodium glutamate leftovers, 20 to 40 percent of powdered rice hulls, 3 to 8 percent of water retainer, 2 to 5 percent of adhesive and 0.2 to 0.5 percent of root promoter. The organic medium special for raising rice by mechanical seedling transplantation is pollution-free and toxin-free, meets the requirements on environmental protection and low carbon, and is an optimized medium for developing mechanical rice seedling transplanting production.

Description

technical field [0001] The invention belongs to the technical field of rice culture substrates, and in particular relates to a special organic substrate for machine-transplanted rice seedlings and a production method thereof. Background technique [0002] In recent years, with the country's emphasis on agricultural production and food security, support policies for food production have increased, and machine-transplanted rice has developed rapidly. However, at present, machine-transplanted rice adopts soil seedling cultivation and transplanting with soil, and the required nutrient soil is all taken from farmland or forest land cultivation layer, and a large amount of soil is taken every year to seriously damage the soil cultivation layer. According to calculations, every 1500 mu of machine-transplanted rice seedlings will destroy 1 mu of farmland or forest land cultivation layer soil. At the same time, it takes a lot of labor to make, transport, and store the bed soil for s...
