Since 1991, I have introduced some new varieties of pear precocious pits from different places in succession. After the trial cultivation, I found that “Cui Guan” breeds outstanding performance. Spring 1995 expansion of 1.2 acres continue to observe. The park was originally paddy field, groundwater level is high, effective soil less than 0.5 meters, so the use of ultra-dense cultivation, spacing of 1 m × 4 m, pollination varieties of “yellow”, “Cuiguan” and “yellow” The ratio is 2: 1. Planting did not dig planting holes, in May in planting ridge laying a layer of sheep manure, the amount of about 1500 kilograms by the end of October heavy base fertilizer, with chicken manure 3000 kg, superphosphate 100 kg. From May to June 1996 topdressing 3 times, each time the import complex
