According to the summarization of the popularization of varieties and cultivated technology and high yield square of Jilin province and Tonghua city in 1996, the formative factors of high yielding population of rice above 10 000 kg/hm² in Tonghua District were analyzed. We have got a synthesis technology which uses polarity big-eared varieties, sound seedling with thin sowing and dry nursery, extra spaced planting, controlled using nitrogen and increasing phosphorus and potassium fertilizer, shallow and wetting irrigation and so on. The formative factors of a high yielding population may be consist of 400 ears/m², 100 grains/ear and 23 grams of 1 000 grains wight above.
