This paper analyzed the advantages and disadvantages of dry-planting and thinning planting of Shanyou 63 and discussed its high-yielding cultivation methods and its corresponding cultivation techniques. It is considered that the seedlings of dry-cultivated and thin-planting rice should be nurtured with close planting density to ensure that the basic tillering seedlings are 67.5-90. 0 million / hm2, the rational operation of fertilizer, nitrogen fertilizer in the base of the ratio of tillering fertilizer and panicle application ratio of 4: 6, expanding the proportion of spike fertilizer, spike in the stability of the premise by attacking the spike to increase production.
