Abstract

The invention provides a saline-alkali soil peanut and witloof interplanting root salinity control method. The root salinity control method comprises the step of laying an infiltration layer, wherein the infiltration layer is prepared from palm kernel shell activated carbon, sepiolite, filbert tree wood bits, akadama soil and melon seed oil cakes. The saline-alkali soil peanut and witloof interplanting root salinity control method has the advantages that the method has the effect of better improving the physicochemical property of soil in saline-alkali soil, after three months, the total porosity of soil of the soil layer 10-30 cm under peanut plants is 52-60%, the total porosity of soil of the soil layer 30-50 cm under peanut plants is 49-58%, the soil salinity of the soil layer 10-30 cm under peanut plants is 0.16-0.20%, and the soil salinity of the soil layer 30-50 cm under peanut plants is 0.16-0.21%.

Description

technical field [0001] The invention relates to a root salt control method for interplanting peanuts and chicory in saline-alkali land, which belongs 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. [0003] From the current point of view, how t...
