experiment example

[0041] Experimental example: A farmer professional cooperative in Dingxiang County is located in the moderately severe saline-alkali area along the Hutuo River in the north-central part of Shanxi Province. In 2015, the rhizosphere salt-avoiding asparagus cultivation technology was tested on 120 mu of moderately severe saline-alkali land, and the initial test was successful. After that, the cultivation has been expanded year by year. In 2016, 110 acres were newly planted, in 2017, 200 acres were newly planted, in 2018, 170 acres were newly planted, and in 2019, 400 acres were newly planted. The total cultivation area has reached 1,000 acres. Most of the arable land (wasteland) of the cooperative is sulfate and chloride saline fluvo-aquic soil, a small part contains carbonate salinized fluvo-aquic soil, the soil texture is sandy loam, the total salt content of the soil in winter and spring is more than 5g / kg, and the planting is generally salt-tolerant Crop seedlings are difficul...

Abstract

The present invention belongs to the technical field of plant cultivation and provides an asparagus rhizosphere salt-avoiding cultivation method for moderate and severe saline-alkali soil aiming at solving a problem that current asparagus is difficult to cultivate in the moderate and severe saline-alkali soil with total salt content of 3.0 g/kg or more. No irrigation and no rotary tillage are conducted before asparagus planting in spring, mechanical deep ditch digging and large ridge forming are conducted, salt-enriched surface layer soil is concentrated on ridge backs, field surfaces with alternate ditches and ridges are formed, concentrated fertilization and asparagus planting are conducted in ridge ditches, the ridges are flattened and the ditches are filled after autumn, less-salt soilon the ridge blacks rinsed with rainwater in summer and autumn is used to backfill the ridge ditches to accept soil salt ascending along with moisture evaporation in winter and spring, and asparagusrhizosphere avoids a salt-enriched surface soil layer all year round. The asparagus can be cultivated in the moderate and severe saline-alkali soil with the salt content of 3.0 g/kg or more, survivalis ensured and the asparagus grows normally, and effects of high yield and high efficiency are obtained.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a salt-avoiding cultivation method for rhizosphere of asparagus in medium-severe saline-alkali land, and asparagus cultivation in medium-severe saline-alkali land with the rhizosphere salt-avoiding cultivation method as the core. The present invention is suitable for the cultivation of asparagus in medium-to-severe saline-alkali soils with a total salt content of more than 3.0 g / kg. The rhizosphere salt-avoiding cultivation method is simple to operate and easy to popularize. It is not limited to the cultivation of fruit trees, forest trees and other crops in medium and severe saline-alkali land. Background technique [0002] There are a large number of saline-alkali lands in my country, and asparagus can be grown in mildly saline-alkali lands with a salt content below 3g / kg. The normal growth of asparagus can be realized by adopting measures such as ditches ...
