According to the change of the enemy\'s quantity and the qualitative theory of the differential equation, we research the spruce aphides and its predator system. At the same time, we discussion the spruce aphid multiplication model when the natural enemy quantity is a certain value and the periodic oscillating model whose the quantity of the natural enemy changes along with the time. Obtains the stability condition of the balance point and the limit-cycle existing condition, the system presents the dissipative structure\'s character. Finally it explains that this theoretical analysis has certain practical significance regarding the preventing and controlling harmful insect.

第五章，松毛虫与其天敌的关系是食饵和捕食者的关系，根据天敌数量的变化，利用微分方程定性理论，研究松毛虫与天敌系统，讨论天敌数量为一定时的松毛虫增殖模型和天敌数量随时间变化的周期振荡模型，得到正平衡点全局稳定性和极限环的存在条件，通过计算机模拟，说明周期振荡的捕食模型能够呈现典型的时间耗散结构特征，对于防治害虫有一定的实际意义。

This thesis points out three conditions of favorable soil-returning volume,and gets the critical water-content coefficient of bed-irrigating sowing, andthinks that water volume, soil—returning in volume and initial soil water contentcoefficient affects differently the course and the result of infiltration, and revealsthe laws of variations of soil moisture content, and shows the different effect onsoil - wedded states of water volume, depth of seed ditch, soil apparent density,soil-covering depth,initial soil moisture content, width of seed ditch and soil-wedding states, and suggests that the soil-wedding state watering after sevendays is use to evaluate the quality of bed-watering seeding.

结果表明灌水量、种沟宽度、回土量和土壤初始含水率对入渗过程和入渗结果存在不同影响；揭示了坐水播种土壤含水率在种沟断面上的变化及其随时间的变化规律，模拟结果还表明了灌水量、种沟深度、土壤容重、覆土厚度、土壤初始含水率、种沟宽度、回土量对土壤湿润状况的影响及确定适宜回土量的三个条件。
