Total flower sequence, flower beige, fruit ball, fruit leather, inner peel hard, beige to light brown.the most suitable growth temperature is 15-30 degrees C, above 30 degrees C growth is seriously hindered, 10 degrees C stop growing, the elderly tree can withstand short-term -4 to -5.6 degrees C low temperature, in the annual precipitation of 1300-3000 mm, dry and wet season obvious tropical and warm frost-free subtropical areas cultivated optimally. Areas with annual precipitation of less than 1140mm and no irrigation conditions should not be planted. The soil is deep and fertile, well drained, pH4.5-6.5, below 770m above sea level is the most suitable garden.only 2 species are edible, i.e. photoshell and coarse shell species and their hybrids.seedlings can be grafted or planted for reproduction. Picking yang, strong, old cooked branches 10-22cm, retain the top 2-4 round leaves, inserted in a humid sand bed, to maintain 24 degrees C cultivation; Line distance of 10-12 meters, plant distance of 4-5m, plant 165-255 plants per hectare, south China can be slightly dense, and in the previous period to plant other crops or fruit trees.
