Abstract: Five improved varieties of prune （Prunus domestica L.） were selected as the research objects, and the agronomic characters and adaptability of different varieties of prune were analyzed by the experiment of density, water and fertilizer integration and cold resistance. The results showed that, under the planting density of 5.0 m×2.5 m and reasonable control of water and fertilizer, Goddess prune and France prune needed three layers of protection in the first year, two layers of protection in the second year, and could safely overwinter without protection in the third year with good cold resistance. The planting density of Red prune, Blue prune and Xinmei No. 1 were 4.0 m×2.0 m under reasonable control of water and fertilizer, three layers of protection for overwintering were required in the first year, two layers in the second year, and one layer in the third year. With the reasonable supporting cultivation techniques, five prune varieties could safely overwinter and were suitable for planting in northern Xinjiang.

Key words: prune（Prunus domestica L.）, cultivation pattern, cold resistance
