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

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

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

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