Introduction and salt-and-alkali-resistant cultivation method for jerusalem artichoke

Abstract

The invention discloses an introduction and salt-and-alkali-resistant cultivation method for jerusalem artichoke. The method adopts a traceable introduction method to introduce different wild-type jerusalem artichoke germplasm resources into the same latitude coastal area in China for ecological self-adaptive domestication and salt-and-alkali-resistant adaptation exercise, and obtains the jerusalem artichoke germplasm resources with good agronomic traits, strong salt and alkali resistance and high economic yield through screening, on this basis, portunus trituberculatus aquatic water stressesof different concentrations and gradients are performed on the jerusalem artichoke germplasm resources to further improve the ecological adaptability and salt and alkali resistance of the jerusalem artichoke germplasm resources. The introduction and salt-and-alkali-resistant cultivation method for the jerusalem artichoke has the advantages that the operation is simple, convenient and efficient, the practicability is strong, the popularization and application are easy, the defects of the wild-type jerusalem artichoke germplasm resources can be overcome that the introduction is difficult, the salt-and-alkali-resistant ecological adaptability is poor, and the yield, quality and characters are poor, and the method effectively introduces the jerusalem artichoke and improves the ecological adaptability of the jerusalem artichoke in saline-alkali lands.

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...

AI Technical Summary

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
