寒地水稻三超栽培技术研究

Summarize in the Study of 3-S Cultivating Technique of Rice in Cold Zone

水稻三超栽培技术针对寒地稻作再高产的障碍因素,利用大钵盘超早超稀定位播、培育均质多蘖壮秧,宽行单本适期移栽,深施肥、控灌水等强化及安全栽培措施,延长水稻生育期、扩大营养空间、释放个体生产潜力,开发低节位优势分蘖,从而形成具有高光效、超高产群体的栽培技术体系。

3-S cultivating technique puts forward the obstruction of higher yield of rice production in cold zone. It make use of big pot to sow with single seed at earlier stage (proper),to foster vigorous seedlings. Single seeding was transplanted with super wide spacing planting at proper stage, applying fertilizer in deep layer of field and controlling Irrigating. By using above cultivation methods, it can prolong rice growth period, enlarge nutrient space, release individual productive potentiality, make full use of low tillers, then it can form a cultivating technique system with achieve active photosynthesis and high yield plant populations.
