不同处理对花生鸟害和出苗率的影响

Influence of different treatments on bird damage and emergence rate of peanut

为了研究花生(Arachis hypogaea Linn.)鸟害和出苗率,设置3个重复试验,每个试验17个处理,每个处理播种花生10株,每株播种2粒花生种子(处理8除外)。结果表明,花生种芽遭到乌鸦啄食,3种对照出苗率平均为52.22%,花生饼肥和商品复合肥处理出苗率均为3.33%,单粒米处理出苗率为73.33%,而秘方(SF)处理出苗率为93.33%;只有硼肥处理花生出现黄苗,黄苗率为16.67%。方差分析表明,花生饼肥、商品复合肥、单粒米、硼肥4种处理与对照差异显著(P<0.05,下同),其他处理与对照差异不显著。由此可知,花生饼肥和商品复合肥引诱乌鸦啄食花生种芽,秘方(SF)处理与之相反;与单粒米种子相比,乌鸦显著偏爱啄食双粒米花生种芽;供试剂量的硼肥处理导致花生苗变黄。

In order to study the bird damage and germination rate of peanut(Arachis hypogaea Linn.),three copies of trials were designed,17 treatments were prepared for each trial,10 pits were sowed for each treatment,and 2 peanut seeds were included for each pit(except treatment 8).The results showed that the sprouts of peanut were pecked by crows,and the average emergence rate of three controls was 52.22%.The emergence rate of peanut cake fertilizer and commercial compound fertilizer treatment was 3.33%,the emergence rate of single grain rice was 73.33%,and the emergence rate of secret formula(SF)treatment was 93.33%;Only the peanut treated with boron fertilizer had yellow seedling,and the yellow seedling rate was 16.67%.Variance analysis showed that peanut cake fertilizer,commerical compound fertilizer,single grain rice and boron fertilizer had significant difference with the control(P<0.05,the same below),while other treatments had no significant difference with the control.Therefore,peanut cake fertilizer and commercial compound fertilizer induced crows to peck at peanut seed buds,but SF treatment was the opposite;Compared with single rice seed,crow preferred to peck double rice peanut seed buds significantly;The treatment of boron fertilizer at the tested dose led to the yellowing of peanut seedlings.
