The research put forward the concept of parasitic system for the first time and studied distribution rules of N, P and K nutrients of different soil areas and different plant tissues in the system along with changes in the tomato growth period, as well as relevance between rhizosphere soil and nutrient contents in different plant tissues. It is found in the results that when Orobanche aegyptiaca was parasitized in tomatoes and joined nutrient transmission via a certain channel, the nutrients in tomato rhizosphere soil would firstly be transported into aboveground parts and Orobanche aegyptiaca by its transfusion tissue; content changes of rapidly-available N, P and K in Orobanche aegyptiaca rhizosphere soil, tomato rhizosphere soil and non-rhizosphere soil showed certain high-low complementarity; content changing trends of N, P and K in different organs of tomatoes and Orobanche aegyptiaca had certain relations, but would differ along with variation of tomato growth period; contents of rapidly-available N and K in Orobanche aegyptiaca rhizosphere soil showed significant correlation with total contents of N and K in organs of tomato and Orobanche aegyptiaca.
