摘要: 种植方式多样性是中国水稻生产主要特点之一,对于应对多变的种植环境,提高水稻综合生产能力和保障国家粮食安全具有重要作用。为了揭示不同种植方式下早稻生长发育特性和高产形成特征,本文阐述了我国目前早稻生产和种植方式发展现状,归纳了不同种植方式对早稻根系生长、养分吸收、干物质积累、茎蘖动态、生育期变化、产量和品质形成,以及经济和生态效益的影响,并认为今后可以从不同种植方式下早稻生育进程的内在机理、稻田杂草群落组成及其物种多样性和稻田土壤矿质元素流失特征展开探究。

Abstract: Diversity of planting mode is one of the main features of rice production in China. It plays important roles in coping with variable planting environment, improving the comprehensive productivity of rice and ensuring national food security. In order to reveal the growth and high-yield formation characteristics of early rice under different planting modes, this paper elaborated the current situation of early rice production and development of planting mode in China, and summarized the effects of different planting modes on root growth, nutrient absorption, dry matter accumulation, tiller dynamics, growth duration, yield and quality formation, as well as economic and ecological efficiency in early rice. It is proposed that the researches on the intrinsic mechanism of development process in early rice, the composition and species diversity of weed communities in paddy fields, and the characteristics of soil mineral nutrient loss based on different planting modes are valuable subjects.
