%X Using the orthogo nal quadratic regression design method,a cultivation technology mode to retain r ice high yield with applying fertilizer in extractive quantity is studied,and a numeric mode of the density of rice plan ting,quantity of applying N and quantity of applying P is established,the result s show that the theorical maximal yield of rice is 9211.5 kg/hm2 when the plantin g density of rice is 209628 clumps/hm2,th e application amounts of N and P are 379 .05kg/hm2 and 476.85kg/hm2,respectively.
