Abstract

The invention provides a root salt control method for potato and sesbania interplanting in salt-alkali soil. The method includes the step of laying an infiltration layer, wherein the infiltration layer comprises walnut shell activated carbon, fir wood scraps, zeolite, peat soil and chitosan. The method has the advantages that the method has a good improvement effect on the physical and chemical properties of soil in the salt-alkali soil; three months later, the total porosity of soil in the soil layer which is 10-30 cm deep under potato plants is 58-65%, the total porosity of soil in the soil layer which is 30-50 cm deep under potato plants is 55-63%, the soil salt content of the soil layer which is 10-30 cm deep under potato plants is 0.13-0.18%, and the soil salt content of the soil layer which is 30-50 cm deep under potato plants is 0.14-0.19%.

Description

technical field [0001] The invention relates to a root salt control method for interplanting potatoes and turnips 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 ...
