摘    要:在山东省气候条件下,棉花生长发育主要受热量条件制约。由积温推算出在不同气候生态棉区以及不同品种、种植方式、密度和产量水平下的棉田物候期,由此得到相应棉田各次化调期,可改变田间小气候,提高成铃率10%~15%,单铃重增加0.3~0.9 g,使棉田因蕾期缩短而改变播期及种植品种,扩大麦棉两熟种植区域,提高棉花品质。

关 键 词:气候生态   棉区   化学调控   积温   产量

Abstract:Under the climatic conditions in Shandong Province, cotton growth and development are mainly restricted by heat conditions. By means of phenological stages of cotton fields calculated by accumulated temperature for cotton growth areas with different state of climatic ecology, different varieties, planting ways, density and yield levels of crop, the suitable chemical controlling stages are determined, which could change the microclimate of cotton fields, raise 10%~15% of mature boll and 0.3~0.9 g of one boll weight, and change seeding time and varieties because of shorter button stage, expand areas of double cropping with wheat and cotton, and improve cotton quality
Keywords:Climatic ecology Cotton growth area Chemical controlling Accumulated temperature Yield
