摘要
在物理防治、生物防治、农业防治等方法综合使用的基础上,为了使用药量确保毒副作用小、水稻安全生产、生产成本小等目标得以实现,建立了水稻流行性病虫害传播系统的数学模型,并用变分迭代、同伦映射等方法求出了其渐近解,真正实现科学地使用农药,从而造福人类。
Based on the basis of the comprehensive use about the physical,biological,agricultural control method,It makes the use of dosage possible to ensures the realization of the goals of less toxic and side effects,safe production of rice,low production cost,etc.The mathematical model of the epidemic disease and insect pest transmission system of rice is established,and its asymptotic solution is obtained by means of variational iteration and homotopy mapping,etc.The scientific use of pesticides is truly realized,thus benefiting mankind.
