Abstract

The invention discloses a method for planting salicornia europaea and improving a soil fertility condition on saline-alkali soil. The method comprises the steps of adding of improved fertilizer for the saline-alkali soil, land finishing, sowing, field management and harvest. The improved fertilizer for the saline-alkali soil comprises desulphurization gypsum, activated carbon, fly ash, plant stalkparticles, bentonite, zeolite, urea, ammonium phosphate and blast furnace slag particles with the proportion of (30-40):(10-14):(6-10):(16-18):(8-12):(4-8):(3-5):(3-5):(4-6). According to the method,the survival rate and yield of the salicornia europaea are high, the improvement effect on the whole saline-alkali soil is improved, and the improvement process is environmentally friendly and pollution-free. Therefore, the method is an application technology which is worthy of large-area popularization.

Description

technical field [0001] The invention belongs to the technical field of saline-alkali land improvement, in particular to a method for planting salicornia saline-alkali land and improving soil and fertilizer conditions. Background technique [0002] At present, there are mainly the following technical measures for the transformation of saline-alkali land: [0003] 1. Water conservancy improvement, salt washing with fresh water: suitable for well-drained areas with high terrain. [0004] 2. Biological improvement: improve the micro-ecological environment of saline-alkali land, apply bio-organic fertilizers, supplement organic matter, and increase the number of beneficial microorganisms in the soil, so as to establish a new micro-ecological balance between soil, plants and microorganisms in saline-alkali land, and achieve the goal of biological control. [0005] 3. Chemical improvement: apply about 15 tons of gypsum per hectare, and apply it once as a base fertilizer. It can al...
