Through several years of promotion of rice new varieties and comprehensive cultivation techniques and the summary of high yielding crops at provincial and municipal levels in 1996, the formation elements of high yielding population of 10,000 kg / hm2 in Tonghua City were initially summarized, Large panicle varieties, sparse planting dry nursery seedlings, ultra-thin planting, nitrogen control by potassium, shallow water wet irrigation and other integrated supporting technology, control the number of effective panicles per square meter 400, spikelets over 100, mixed 1000 overweight 23g Formation of high-yielding population.
