1.At harvest,root length density and treflan concentration at different soil layer were evaluated using soil auger method.

1.冬收获后,采用土钻法在滴头附近沿垂直方向分层取样,测定各土层的根长密度和氟灵含量,并统计各区的产量。

2.Field experiment was conducted to investigate the effects of treflan injection on dripper clogging and root distribution,yield and quality of winter wheat.

2.通过田间试验,研究了地下滴灌施加氟灵对滴头根堵塞的控制效应及其对冬产量、品质和根分布的影响。
