Problems solved by technology

[0008] But above each kind of method all exists more or less shortcoming, and each kind of way basically all is a temporary solution but not a permanent cure when used alone, also generally is to take wherein a small aspect to carry out partial governance in the prior art; Therefore, a scientific and effective comprehensive management method is needed to improve the saline-alkali land, fundamentally improve the saline-alkali land, and then use the improved saline-alkali land to plant corresponding economic crops, maintain and improve the improvement effect and bring economic benefits

Abstract

The invention discloses a method to plant Medicago sativa in saline-alkaline soil and improve soil and fertilizer condition. The method comprises: applying an improving fertilizer, plowing, performingrotary tillage and leveling the land, sowing, managing the field, and harvesting, wherein the improving fertilizer is made from desulfurization gypsum, activated carbon, flyash, plant stalk granules,bentonite, zeolite, urea, ammonium phosphate, blast furnace slag particles and a microbial agent having a weight ratio of (30-40):(10-14):(6-10):(16-18):(8-12):(4-8):(3-5):(3-5):(4-6):(1-3). saline-alkaline soil is improved by taking the measures such as saline-alkaline soil improving fertilizer and planting Medicago sativa, the survival rate and yield of Medicago sativa are high, the improving of the whole saline-alkaline soil is excellently effective, and the improving process is green and free of pollution. Therefore, the method is an application technique worthy of wide popularization.

Description

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