Abstract

The invention provides a root salt control method with a perlite percolation layer. The root salt control method includes the step of percolation layer laying; the percolation layer comprises perlite, walnut active carbon, jujube-shell active carbon, cotton straw and humus soil. The root salt control method has the advantages that the root salt control method with the percolation layer has the good improvement effect on the physicochemical properties of soil in saline-alkali land; three months later, the volume weight of soil in the middle of an acer-mono main root is 1.23 g/cm<3> to 1.31 g/cm<3>, the volume weight of soil at the lower portion of the acer-mono main root is 1.24 g/cm<3> to 1.34 g/cm<3>, the salt content of the soil in the middle of the acer-mono main root is 0.16% to 0.21%, and the salt content of the soil at the lower portion of the acer-mono main root is 0.14% to 0.21%.

Description

technical field [0001] The invention relates to a root salt control method using a perlite percolation layer and its application in the planting of maple pentagon 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. ...
