Problems solved by technology

The coastal saline soil planting industry is also not optimistic. The main reasons are: 1. The introduced and bred salt-tolerant plants have poor ecological adaptability and low economic benefits, making it difficult to popularize; obvious
3. The traditional saline-soil agricultural technology system is not perfect, and the market traction is not strong, which seriously restricts the sustainable development of saline-soil agriculture

Embodiment Construction

[0020] The present application will be described in detail below in conjunction with specific embodiments.

[0021] 1. Basic situation of the test site

[0022] The test site is located in Xiyou Town, Laizhou City, Shandong Province-Nanjing Agricultural University Ocean "863" Pilot Test Base, about 3km away from the coastline. This area belongs to the warm temperate East Asian monsoon continental climate, with an average annual rainfall of 550mm and a minimum year of 334.5mm, and the rainfall is mostly concentrated from June to September; the annual average evaporation is 2116.2mm.

[0023] 2. Test materials and methods

[0024] The tested plant was Jerusalem artichoke (Helianthus tuberosus L.), and three wild species were collected from Qinghai, Shaanxi, Henan and other provinces. The whole growth period of each wild species was about 180-210 days. The soil used in the test is coastal desalted sandy loam, and its basic physical and chemical properties are shown in Table 1. ...

Abstract

The invention discloses a method for introducing Jerusalem artichoke and salt-alkali resistance cultivation. The method adopts a traceability introduction method to introduce different wild-type Jerusalem artichoke germplasm resources to coastal areas at the same latitude in my country for ecological adaptive domestication and salt-alkali tolerance adaptation. Sexual exercise, screening and obtaining Jerusalem artichoke germplasm resources with good agronomic traits, strong salt-alkaline tolerance, and high economic yield; on this basis, it was subjected to water stress for Portunus trituberculatus culture in sub-concentration gradients to further improve its ecological adaptability and resistance. Salinity properties. The method is simple and efficient in operation, strong in practicability, easy to popularize and apply, can solve the shortcomings of wild-type Jerusalem artichoke germplasm resources, poor ecological adaptability to saline-alkali resistance, poor yield and quality traits, etc., and is an effective method for introducing and improving Jerusalem artichoke. Its method of saline-alkali ecological adaptability.

Description

technical field [0001] The invention belongs to the agricultural ecological technology, in particular to a method for introducing Jerusalem artichoke and cultivating it against salt and alkali. Background technique [0002] Based on saline soil ecological high-value agriculture, focusing on the transformation and development of sustainable agriculture and the major needs of promoting rural revitalization, the present invention conducts research on the introduction of medicinal and edible homologous plants, adaptive domestication, and water stress in Portunus trituberculatus cultivation in coastal saline-alkaline areas. Solve the key technical problems faced in the transformation and upgrading of traditional agriculture, cultivate green characteristic agricultural industries, and develop ecological high-value agriculture, and provide new ways and methods for cultivating high-stress-resistant crop varieties. [0003] At present, my country has about 30 million mu of coastal sa...
