Method for planting orchard grass and improving soil fertility condition of sandy saline and alkaline land

Abstract

The invention discloses a method for planting orchard grass and improving the soil fertility condition of sandy saline and alkaline land. The method comprises land preparation, seed treatment, seeding, field management and harvesting in due time. Improving fertilizers A and B for the sandy saline and alkaline land are added during planting. The fertilizer A comprises plant straw granules, animal manure, attapulgite clay, humic acid, peat, a saline and alkaline land improver and microbial powder in the weight ratio being (25-35):(20-30):(14-16):(14-16):(8-12):(2-4):(1-3). The fertilizer B is asandy soil adhesive comprising gelatin, sodium silicate, modified waterborne polyurethane, gypsum, rosin and manganese dioxide in the weight ratio being (35-45):(8-12):(18-22):(16-20):(4-8):(4-8). Measures such as the improving fertilizers for the sandy saline and alkaline land and planting of orchard grass are taken to improve the saline and alkaline land, the yield of the orchard grass is high,the soil improvement effect on the whole sandy saline and alkaline land is outstanding, the improvement process is green, environmentally friendly and pollution-free, and the method has good economicand social benefits and thus is an application technology worth 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 wild grass 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. ...
