The dragon fruit can be planted all year round, note that it should not be planted y, implanted about 3cm deep can be, the initial period should keep the soil moist.
The dragon fruit grows rapidly in a warm, moist and well-lit environment. Spring and summer open field cultivation should be more watering, so that its root system to maintain vigorous growth, in rainy weather should be drained in a timely manner, so as to avoid infection with pathogens caused by stem rot. Dragon fruit can withstand low temperatures of 0 ℃ and 40 ℃ high temperature, in order to ensure its perennial growth and many times the results, the greenhouse temperature should try to reach its appropriate growth of 20 ~ 30 ℃.
Northern regions planting dragon fruit must be built greenhouse, winter night temperature should not be less than 8 ℃. Summer may not remove the plastic film, but must be ventilated. Dragon fruit orchards do not have to plow, cut weeds in a timely manner. p>The propagation method of dragon fruit
1, cuttings
Cuttings in the spring is the most suitable time, the plugs selected full-grown stem nodes, cut off the length of 375px small section, until the wound air-drying inserted into the sand bed or cuttings directly under the support frame and the side of the cement column. The cuttings do not need to be watered later, keep the soil dry and start watering after 10 days. Roots can be produced in about 15-30 days, and the roots will be transplanted to the seedbed when they reach 3-100px in length.
2, grafting
Select no pests and diseases, robust growth, stem flesh full of "measuring tape" as rootstock, grafting in sunny days. Dragon fruit stems with a knife cut plane, the scion inserted, aligned with the formation layer, tied with cotton thread fixed, in 28-30 ℃ conditions, 4-5 days the wound joint surface that there are a large number of healing tissue formation, scion and rootstock color close to the two vascular bundles have been healed, grafting is successful, and then can be moved into the pseudo-planting bed to continue to cultivate.
