Embodiment Construction

[0025] The technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] In the genetic resource information of the varieties involved in the method of the present invention, the alfalfa variety is "Gannong No. 3" (Medicagosativa L. cv. Gannong No. 3), and the wheat variety is the hybrid Ningchun No. 4 (Triticum aestivum. L. cv. .Ningchun No.4), and the corn variety is the hybrid Longdan No. 4 (Zea mays Linn. Sp. Longdan No 4).

[0027] 1 Materials and methods

[0028] 1.1 Overview of the test site

[0029] The experiment was carried out at the Grass Station of Gansu Agricultural University, Huangyang Town, Liangzhou District, Wuwei City, Gansu Province. This area is located at the eastern end of the Hexi Corridor in Gansu Province, at 103°5′E, 37°30′N. It is a cold temperate arid region with a typical continental climate, with abundant sunshine, windy and sandy springs,...

Abstract

The invention discloses a method for testing the effect of medicago sativa L.-corn / wheat rotation on soil. The method is characterized in that Gannon No. 3 medicago sativa L. is taken as a test material to study the effect of different rotation treatments of medicago sativa L.-corn (AC), medicago sativa L.-wheat (AW), medicago sativa L.-corn-corn (ACC) and medicago sativa L.-wheat-wheat (AWW) (bytaking a un-ploughed 5a medicago sativa L. grassland as a control, CK) on soil nutrient content, microbial population and medicago sativa L. auto-toxic substance content change. Results show that through the rotation of corn and wheat by medicago sativa L., population structures of soil microorganisms can be significantly improved, the auto-toxic substance content is reduced, and nutrients are increased in consumption and are decreased in accumulation.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a test method for the influence of alfalfa-corn / wheat rotation on soil. Background technique [0002] Alfalfa (Medicago sativa L.) has multiple functions such as excellent feed value and nitrogen fixation, water and soil conservation, and soil improvement, and is planted on five continents in the world. Studies have confirmed that alfalfa has a special intraspecific allelopathic effect—autotoxicity. Alfalfa seeds contain water-soluble autotoxic substances, and continuous planting for many years will lead to the accumulation of soil autotoxic substances, which will cause autotoxicity to the germination of alfalfa seeds and the growth and development of seedlings, which will reduce the yield and quality of alfalfa. It is urgent to explore scientific and effective ways to reduce the obstacles and autotoxicity of alfalfa continuous cropping, and then improve the yi...
