Abstract
The invention discloses a method for preparing a selenium-rich rice stem cell growth promoter, relates to the technical field of plant nutrition, and aims to solve the problem that the root system of rice is slow in the growth process. After the promoter is applied, the growth is rapid, the stem and leaf are luxuriant, the root system is developed, the disease resistance is strong, and the nutrition of the fruits is rich.
Description
Technical Field
The invention relates to the technical field of plant nutrition, in particular to a preparation method of a selenium-rich rice stem cell growth promoter.
Background
The rice is one of the staple food grains in China, is used as a large-area agricultural product and is planted in a large area at home, but the content of nutrient components and trace elements in the rice is continuously reduced due to the loss of soil nutrition after long-term cultivation, so that the health of the public is greatly influenced.
Plant stem cells are relative to mature tissues that have differentiated to mature within the plant. Typically, a plant's stem cells are two "clumps" of cells within the plant. These two clusters of cells are located in the apical meristem and root apical meristem of the plant, respectively. Plant stem cells are the root cause of plant viability. The plant stem cells have remarkable regeneration capacity, and the deep-rooted and lobate plants can be continuously promoted only by promoting the growth of the plant stem cells.
In the process of fertilizing the rice, as the root system is immersed in water, the components of the fertilizer are easy to dilute, so that the cost is increased, in order to better supplement nutrients and promote the growth of rice stem cells, the selenium-rich fertilizer with the slow release capability is needed, and guarantee is provided for the safety of grains and the health of the public.
