A good prenatal fertilizer: inadequate basal fertilizer, jujube without fertilization before winter, make fertilizer before flowering, Jujube for nutrition, prompting more flowers and more fruit, on the yield, increase income have a significant role. Should be in late April to early May, each adult jujube tree throwing excrement 15 to 20 kg, or urea 1 kg, Duishu irrigation facilities, but also mixed phosphorus, potash. Second, the flowering girdling: robust growth, age more than 10 years Sheng fruit jujube trees, early in full bloom (60% to 70% inflorescence open), with a knife from the ground about 15 to 20 cm on the trunk of the skin Scratch in a circle, a width of 1.5 cm. Then, in the area where the skin is scraped off, cut 0.4-0.6 cm with a ring cutter to reach the xylem, but do not injure the xylem.
