Calla lilies, alias Cigu flower, water taro, Guanyin lotus. Belongs to the genus Calla of Araceae. Calla lilies are perennial bulbous herbs. Plant height 25-50cm, underground with hypertrophic fleshy rhizome. The rhizome grows roots downward and stems upward. Leaf blade basal, arrow-shaped or lanceolate, entire, bright green, with white or yellow spots on the leaves of some varieties; petiole long, lower part sheathed. The ornamental part is actually a roll funnel-shaped bract and a protruding core column in the bract. This flower pattern is called the "Buddha's bud". Its colors are white, yellow (golden yellow, light yellow), red (pink, purple, orange-red), green and so on. Bracts contain yellow or light green cylindrical fleshy inflorescences. The florescence is winter and spring, and spring is the most prosperous.

1. Hydroponic method

The main results are as follows: (1) the hydroponic nutrient solution of calla can be sold in the market.

(2) at the initial stage of calla growth, the concentration of nutrient solution can be controlled at 1 stroke 2 of the prescribed concentration, and can be appropriately increased to the specified concentration in the middle and later stage of growth, and the pH value of nutrient solution should be adjusted to 5.6-6.5 during the whole growth period.

(3) the root system 1-2-2-3 can be soaked in nutrient solution. Hydroponically cultured calla lilies are shown in the picture.

two. Maintenance guide

The main results are as follows: (1) the temperature and light suitable for calla lily growth is about 20 ℃. If it is lower than o ℃, the rhizome will be frozen to death. Calla lilies need sufficient light in winter and shade when the sun is too strong in summer.

(2) change the water every 2-3 days in the initial stage of changing water. It is easy to rot the root at the beginning of hydroponic culture. It is necessary to remove the rotten root in time and clean the root during the change of water. The water can be changed about 7 days after it grows and takes root.

(3) during the watering period, more water should be sprinkled on the leaf surface to keep the leaf surface moist and clean.

(4) fertilized calla lily seed bulb contains a lot of nutrients, such as short-term hydroponic culture can not add nutrient solution; if long-term hydroponic culture is needed, nutrient solution can be added once every 30 days.

(5) hydroponic calla lotus is not easy to get sick, so it is only necessary to make sure that it is healthy and disease-free when selecting bulbs.

How to improve the success rate of hydroponic culture of calla lily

The root system of calla lily is difficult to adapt to hydroponic environment, so it is difficult to change from soil culture to hydroponic culture. In order to improve the survival rate, hydroponic culture of planting bulbs is generally chosen. The selection of bulb should be robust and disease-free, bright color, full bud eyes, and the diameter of bulb should be 3-5cm. The correct selection of balls is the first step in successful hydroponic culture of calla lilies.
