A Study on the Biolgical Characteristics of Ziziphus mauritiana at Hot and Dry Valley

  • Received Date: 1993-08-22
  • A research was made during 1987~1989 on the phenology, regular growthpatterns,root system and vigor of sprouts of Ziziphus mauritiana Lam. at hot-dry valley ofYuanjiang County,Yunnan Province. The results have shown that the growing incrementfrom June to August accounts for 40%~50% of the whole growth of a year. Root system is well developed with a strong main root.The stumps are vigorous in rejuvenation and theirshoots of 4 months are long enough to be inoculated with lac insects.The average height ofthe transplanted seedlings can be up to 240 cm within 3 years;canopy 180 cm×220 cm ap-proximately;branches 2~3;length of shoot 65 cm. The total length of the useful shoots ofa tree is about 290 cm.
