优质粳稻龙粳27精确定量肥密技术研究

Precise Quantification Fertilizer and Density Technology of Japonica Longjing 27

通过设计低、中、高3个肥量和4个密度的试验对龙粳27进行精确定量肥密研究。结果表明:高肥的分蘖好于低肥,但低肥高密度(30穴·m^(-2))的处理产量最高,空瘪率低,表现最好。

Precise quantification fertilizer and density on Longjing 27 was studied by designing 3 fertilizer application and 4 densities experiments.The results showed that tiller of high level fertilizer application was better than that of low level fertilizer application,but the highest yield,barrenness low,the best performance were obtained in the treatment of low leve fertilizer application and high density（30 hole·m^（-2））
