摘 要:在北方不同土壤气候条件下的试验结果证明旱育稀植水稻以壮秆大穗和高度结实增产,具有稳定高产潜力。从个体发育和群体结构的形态机能入手,阐明了旱育稀植水稻高产机理:单株茎秆干重大,上部叶片长,基部节间粗壮,茎秆大维管束数量多是形成壮秆大穗的基础;叶片较厚,上位三叶叶片较长但保持直立,形成高光效的冠层结构,穗颈大维管束截面积大,是高度结实的基础。分析比较不同土壤气候条件下旱育稀植水稻初期和后期生育特点,提出了我国北方旱育稀植三种技术类型。Result showed that rice of drought seedling and sparse plant could increase yield due to strong stem, long spike and high fertile, and stablize high yield potential, Studlng morphology function of individual developand population struction, anther clarified high yield fandament about rice of drought seedling and sparse plant as follows: 1 The foundations which strong stem and big spike were obtained were heavy dry weight per plant, longer upper leaf, thicker basilar internode and more vascular bundle. 2 Thicker leaf, longer and erect upper three leaves, shoot layer of high photosynthetic efficiency, thick neck of spike and large section vascular bundle were foundtions which high fertile was ob(?)ained. Analysing and comparing growth traits in prophase and anaphase of rice of drought seedling and sparse plant on various soil and climate, three technique types which could be used in the north were put forward.
