Analysis on Dynamic Change of Tiller Angle under Different Cultivation Conditions in Rice

Yu Yahui, Xu Zhengjin(Rice Research Institute, Shenyang Agriculture University, Shenyang 110161)  
The effect of different cultivation on tiller angle was studied by using 3 varieties with different panicle types. The result showed: During the beginning of tiller period and milky period the change of tiller angle under different transplant rice seeding depth (TRSD) was significance: 0.5cm1.0cm1.5cm; Tiller angle under different fertility levels: 1.5g1.0g0.5g; Different water depth had little infection to tiller angle. According to experiment the conception and mensuration of tiller angle were discussed. The relationship between tiller angle and row space was studies. The formula of tiller angle was suggested: tgα=R/2H, and used it to design the better plant density.
