选择浙江省临安市2个地力和栽培技术相近、小气候环境不同的规模化稻作区域作为分析对象,比较了2010—2012年2地降水、气温年际变化,及超级稻产量动态,并且着重分析2012年2地的甬优12高产田块及生育期间降雨、气温情况,来探讨降雨和气温条件对超级稻发挥超高产潜力的影响。结果表明:分蘖期和全生育期积温高、灌浆结实期雨水少的气候条件利于超级稻超高产潜力的发挥。
In this paper, two large-scale paddy rice fields with similar soil fertility and cultivation techniques and different microclimate environments were selected as the analysis objects. The precipitation, temperature variation and super-rice yield dynamics during 2010-2012 were compared and analyzed. 2012 in two Yongyou 12 high-yield plots and rainfall during the growth period, to investigate the rainfall and temperature conditions on super-super rice to play a super-high yield potential. The results showed that climatic conditions with high accumulated temperature during tillering stage and whole growth period and few rainfall during grain filling period were favorable to the super high yield potential of super rice.
