中少蘖、偏大穗品种代替多蘖小穗是水稻生产发展的必然趋势，因其改善通风透光条件，提高成熟度、结实率，而具有很高的增产潜力。但目前实际生产上仍以密植、促分蘖为主要栽培技术手段，施肥次数少且用量集中，单方面强调分蘖，忽视水稻正常的分蘖机能和生理平衡，破坏了... It is an inevitable trend for paddy tillers to produce less tillers and bigger bulbs instead of more tillers. It has high yield potential due to the improvement of ventilation and light conditions, maturity and seed setting rate. However, the actual production is still close planting, and promote tiller as the main cultivation techniques, fertilization frequency and the amount of concentrated, unilateral emphasis on tillering, ignoring the normal rice tillering function and physiological balance, destroying the ...
