Sandy soil is the most suitable for the growth of imperial flowers. In family breeding, the flowerpot should also choose a slightly larger pottery basin with good air permeability.
Temperature: the winter temperature of imperial flower is generally no less than 7 ℃, and the summer temperature is 27 ℃. Individual varieties can withstand low temperature, zero degrees Celsius will not frostbite.

The matrix is mixed with peat and perlite according to the volume ratio of 4:6, the pH value is adjusted from 5.5 to 6.5, and the EC value is less than 0.5. The cuttings were soaked with 1000 ppm indole-3-butyric acid solution for 15 minutes and then dried immediately. The cutting depth is 1 /3 ~ 1 /4 of the cutting length. After cutting, the management should be carried out according to the conventional technology, and the field transplanting should be carried out after seedling emergence.
Emperor flower spurts huawang 3 in the growth period, which can transform the vegetative growth function into the reproductive function, inhibit the growth of the main shoot, promote flower bud differentiation, blossom more, fruit more, and promote development. Then spray the fruit pedicel in the young fruit stage to improve the nutrient delivery. Prevent falling flowers, fruit, dead fruit and abnormal fruit. Make the fruit color beautiful, fruit type beautiful and taste good.
