Abstract

Rice is a major food crop of India. The rice cultivation has maintained its priority status in the agricultural sector of the country. The intensive management practices adopted by the practitioners have resulted in genetic erosion, thus affecting the species composition of the rice field ecosystems. There is obvious difference in species composition and community structure in upland and lowland rice fields and lowland fields has minimum pests affecting production of yield per hectare. This paper presents a work carried out on the biological diversity of lowland rice field ecosystems of India, and proposes the need for conservation strategies to ensure the sustainability of these rice growing ecosystems in the long run.
比哈尔邦萨兰地区稻田水生昆虫生物多样性的时间变化
水稻是印度的主要粮食作物。水稻种植一直保持其在该国农业部门的优先地位。从业者采用的集约化管理做法导致了遗传侵蚀,从而影响了稻田生态系统的物种组成。旱地与低地稻田在物种组成和群落结构上存在明显差异,而低地稻田对单产的影响最小。本文介绍了印度低地稻田生态系统的生物多样性,并提出了保护策略的必要性,以确保这些水稻种植生态系统的长期可持续性。
