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

冬小麦收获后,采用土钻法在滴头附近沿垂直方向分层取样,测定土层密度和氟灵含量,并小区产量。

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系入侵堵塞控制效应及其对冬小麦产量、品质和系分布影响。
