对北方水稻超稀植栽培技术创建的科学解析Ⅰ——兼论穗数增产与粒数增产

Analysis on the Building of Superior Thin Planting in Northern Rice——Increasing Production on Spikelet Number and Increasing Production on Grain Number

阐述了北方水稻超稀植栽培技术的研究及发展,说明了超稀植栽培技术选择少蘖、大穗型品种的原因,从适宜栽培密度、生态特点等方面开展少蘖、大穗型品种稀植技术选择分析,对超稀植栽培中少插基本苗进行技术剖析,同时对超稀植栽培中减少分蘖肥、重施穗肥进行理论解析。

Research and development of superior thin planting in northern rice were expounded, it explained the reason to select the variety with few tillers and large spike, the technology of superior thin planting with few tillers and large spike variety was analysed from cultivated density and ecological characteristics, it analysed the technology of reducing basic seedling during superior thin planting, at the same time it made a theoretical analysis on reducing tillering fertilizer and increasing panicle fertilizer.
