Abstract

The invention discloses a method for planting indigofera pseudotinctoria in sandy saline-alkali land and improving soil fertility conditions. The method comprises the steps of: land parcel preparationwith a mixed fertilizer used for improvement of the sandy saline-alkali land, seed treatment, sowing, field management and timely harvesting, wherein the mixed fertilizer used for improvement of thesandy saline-alkali land includes the following components: desulfurized gypsum, coal fly ash, an organic fertilizer, fulvic acid, clay, a sandy soil binder, a composite water-retaining agent, a saline-alkali land improver, expanded vermiculite and microbiological powder in a weight ratio of (22-30):(8-12):(18-22):(12-16):(6-10):(6-8):(4-8):(4-6):(2-4):(0.5-1.5). The method provided by the invention adopts measures of applying the mixed fertilizer used for improvement of the sandy saline-alkali land and planting the indigofera pseudotinctoria to improve the saline-alkali land, the survival rate and yield of the indigofera pseudotinctoria are high, the improvement effects on the whole saline-alkali land are prominent, and the improvement process is green, environmentally friendly and pollution-free, so that the method is an application technology that is worthy to be promoted in a large area.

Description

technical field [0001] The invention belongs to the technical field of saline-alkali land improvement, in particular to a method for planting horse thorns and improving soil and fertilizer conditions in sandy saline-alkali land. 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...
