稻田昆虫常规取样与机动吸虫器取样效率的研究
Studies on the Sampling Efficiency by Traditional and Motor-Sucking Methods for Insect Collection in Field Condition

摘要: 本文利用东方红-18型机动喷雾器设计吸虫机构,使得该机喷雾、取样一机两用。同时,对吸虫器的取样效率、取样范围以及不同取样方法对稻飞虱种群数量、空间分布估计的聚集度进行比较,研究结果表明,吸虫器的取样效率达91.58%.Abstract: Dongfanghong-18 motor-driven sprayer has been re-designed for both insect-sampling and spraying usages.A serial of test with different sampling methods had been carried on to compare the sampling efficiency, the range of sampled insects, the accuracy for estimating the population density and spatial distribution of planthoppers.The results indicated that the efficiency of motor-sucking sampler was 91.58%, the highest one among five methods.
