The study was focused on the amount of available water in soil, hydraulic conductivity in soil-root system from different root zones, sap flow from root to stem, compensatory effect of root water uptake, the fruit growth and physiological attibutes, evaporation and transipiration, and plant water use efficiency. Experiment plants involved apple tree, grape, peach, etc. Fruit trees were irrigated in both half root zones or water was continuously supplied to the one-half and the other half kept dry(fixed partial rootzone irrigation, F), or water was alternatively supplied to two halves (alternative partial rootzone irrigation, A).

Firstly, This paper processes geometry filtration based on character of orbit's apogee and perigee after orbit model is analyzed and based. Secondly Space Debris is separated into two kinds, coplanar and not coplanar according as location interrelation of target and debris. In Dynamic filtration's processing, considering prediction time limit and orbit perturbation, secular effects which have increaser effect is considered so that some need catching danger time point is appeased, some law about time when target and debris pass intersectant line each other is inferred, when debris and object are in different plane and some similar law also is inferred otherwise. The time list is arithmetical progression. These laws can improve calculation efficiency remarkably; Lastly orbit predict is a course approaching least distance. Danger time point in the last step become beginning time point from which debris and object's position and velocity are calculated by SXP4 Model which is an analytic model.By result, determine that relative movement trend is closer or apart, farther calculate the interval apart from time when predictive least relative distance occurs. Least relative distance and time when least distance occurs is calculated finally. It is a fast approach course adopting varied interval.
