Abstract

The invention provides a root salt control method for interplanting of peanuts and kochia scoparia in saline-alkali land. The root salt control method comprises the step of laying a percolation and filter layer, wherein the percolation and filter layer is prepared from tea seed and shell activated carbon, alnus cremastogyne chips, perlite, gingko bark and rape seed cakes. The root salt control method for interplanting of peanuts and kochia scoparia in saline-alkali land has the advantages of being good in improving effect on the physical and chemical properties of soil in saline-alkali land. Three months later, the volume weight of soil in the soil layer 10-30 cm below peanut plants is 1.04-1.13 g / cm<3>, the volume weight of soil in the soil layer 30-50 cm below peanut plants is 1.03-1.10 g / cm<3>, the salt content of soil in the soil layer 10-30 cm below peanut plants is 0.14-0.19%, and the salt content of soil in the soil layer 30-50 cm below peanut plants is 0.15-0.21%.

Description

technical field [0001] The invention relates to a root salt control method for interplanting peanuts and Kochia scoparia 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 vie...
