Research Progress on the Characteristics of Yield Advantage Formation in Indica-Japonica Hybrid Rice Cultivated in Coastal Saline-Alkali Land
摘要
Abstract
Currently,China's food security still faces a relatively prominent contradiction among"population,land,and grain".China has 2.34 million hm2 of coastal saline-alkali land and 100 million hm2 of inland saline-alkali land.These saline-alkali lands are rare reserve land resources with enormous potential for comprehensive utilization.Rice is often selected as a key crop for soil improvement in both coastal and inland saline-alkali lands.It can continuously play a special role in integrating"utilization,improvement,and conservation"to gradually optimize the soil.In recent years,indica-japonica hybrid rice has repeatedly set high-yield records in production practices,demonstrating extremely broad prospects for production and application.This paper first provides a systematic review of the impacts of salt stress on rice yield and its components,material production capacity,plant type morphological characteristics,and leaf photosynthetic physiological traits.Secondly,it deeply reveals the morphological and physiological characteristics underlying the yield advantage formation of indica-japonica hybrid rice in coastal saline-alkali land and proposes targeted key cultivation measures for high-yield cultivation of indica-japonica hybrid rice in coastal saline-alkali land.Finally,it discusses and prospects the research on strengthening the mechanism of high-yield cultivation of indica-japonica hybrid rice in coastal saline-alkali land,aiming to provide solid theoretical and technical support for high-yield cultivation and regulation management.关键词
