Abstract

The invention provides a root salt control method adopting a rock-wool infiltration layer. The root salt control method comprises the step of laying the infiltration layer, wherein the infiltration layer contains rock wool, quercus acutissima wood activated carbon, palm shell activated carbon, sorghum straws and kanuma. The root salt control method has the beneficial effects that the root salt control method containing the infiltration layer, provided by the invention, has a good amendment effect on physicochemical properties of soil in saline-alkaline land; and 3 months later, the total porosity of the soil of middle parts of main roots of the wild jujube is 45% to 52%, the total porosity of the soil of lower parts of the main roots of the wild jujube is 44% to 53%, the salt content of the soil of the middle parts of the main roots of the wild jujube is 0.14% to 0.18%, and the salt content of the soil of the lower parts of the main roots of the wild jujube is 0.13% to 0.17%.

Description

technical field [0001] The invention relates to a root salt control method using a rock wool percolation layer and its application in planting wild jujube in saline-alkali land, belonging to the technical field of agricultural utilization. Background technique [0002] At present, my country's water and soil resources can only guarantee 500 million tons of grain production capacity, which is far from meeting the huge demand of the growing population. At the same time, my country's energy shortage contradiction is becoming increasingly acute, and the development of biomass energy must ensure the premise of "food security". my country currently owns coastal tidal flats with a total area of ​​nearly 40 million mu, which are important reserve land resources in my country. The development and utilization of saline-alkali soil in coastal tidal flats can not only provide food sources, but also become the production carrier of important salt-tolerant plants such as energy.
