| 田间喷洒农药后,害虫益虫的种群动态均在农药影响下产生变化。模拟这种变化的模型是: Y=A·exp{BT-C[1-exp(-DT)]}模型的4个参数均有明确的含意。通过参数比较可对不同农药及使用方法作出合理评价。本模型不仅适用于连续增长型生物,也适用于具有迁入迁出变化的非连续增长的昆虫和其他节肢动物。 |

| Abstract: |
| After the insecticides are sprayed over the croplands, the population dynamics of.pests and useful insects changes greatly under the influence of the insecticides. The model simulating this change is change is as follows: Y=A·exp{BT-C1[-exp(-DT)]} The four parameters of this model are clearly endowed with biological Jneanings. Through comgarison othese prametersji a rational evaluation can1 be made for different kinds of insecticides and their application methods.5Phis 'model is suitable for both the continuous and 'discontinuous increase in insect and other arthropod population. |
