鸟鼠危害是影响飞播造林成效的主要限制因素。本文以锡林郭勒盟浑善达克沙地飞播造林为例,通过人工模拟飞播造林试验和大面积飞播成效调查,分析了多效复合剂在飞机播种造林中防止鸟类和鼠兔的效果。研究表明,利用多效复合剂拌种后,对鸟鼠有明显的驱避作用,飞播造林后可提高杨柴等种子保存率20%以上,出苗率提高18%以上,并降低大粒种子(杨柴等)播种量2.25kg/hm2,飞播造林成本可减少123.75元/hm2。
Bird injury and damage by wild rat are the main factors that affect success of aero-sowing forestation.Taking aero-sowing forestation in Hunshandake Sandy Lands as example,through simulating experiments and actual investigation of aero-sowing forestation,the effects of application of the Multi-effect Mixed Reagent for preventing bird injury and damage by wild rat were analyzed in aero-sowing forestation.The results shows that using the seed mixed with this kind of reagent in aero-sowing works had exciting r...
