How to cultivate calla lilies in hydroponic culture

Calla is a sturdy perennial herb of the genus Zantedeschia in the Araceae. It is a kind of potted flowers loved by flower lovers. Its flowers and leaves can be used as cut flower materials. Potted plants of dwarf and small flowers are used to put steps, window sills, balconies and mirrors. They are especially lively and lovely. Let's take a look at how hydroponic calla lilies are raised.

Can calla lilies be hydroponically cultured?

Calla lilies can be cultured in water. Calla is a wet plant, its rhizome retains the hereditary genes of aquatic plants, and the aerated tissue of aquatic vascular bundles is well developed, which can adapt to static water culture in indoor containers under non-pollution cultivation conditions. however, attention should be paid to always maintain the clean state and inorganic properties of the nutrient solution in order to maintain the necessary level of dissolved oxygen in the solution, which is the decisive factor for successful cultivation, otherwise, it will inevitably lead to root rot and death of cultivated plants.

Variety selection of calla lilies

Hydroponic calla lilies usually choose white calla lilies, safflower calla lilies and honeysuckle calla lilies with relatively short and compact plants. for the purpose of large plants, tall green stalks or yellow calla lilies can be selected.

1. White calla: the tuber of white calla is smaller and grows slowly, but it blossoms early, has more flowers, the pedicel is white, the pedicel is large and round, the petiole base is white-green, grows slowly, the flame bract is white, and the tuber with a diameter of 1-2 cm can bloom.

2. Safflower calla: the bracts of safflower calla are rosy red, leaves lanceolate, dwarf, flowering in June.

3. Silver star calla lotus: calla lily, also known as calla lily, is about 60 cm high, with large leaves, white spots, yellow or milky white bracts, purple spots at the base, natural florescence from July to August, and dormancy in winter.

How to cultivate calla lilies in hydroponic culture

1. Solution preparation: the following nutrient solution formula can be used: calcium nitrate 800g, potassium dihydrogen phosphate 210g, magnesium sulfate 250g, potassium nitrate 500g, ammonium nitrate 30g, ethylenediamine tetraacetic acid ferric salt 10g, manganese sulfate 2g, zinc sulfate 1g, boric acid 1.3g, copper sulfate 0.15g, ammonium molybdate 0.1 g.

2. Solution management: in the whole growing period of calla, the pH value of nutrient solution is controlled between 5.6 and 6.5. The supply of nutrient solution is mainly determined according to the weather conditions and plant size, usually 2-3 times a day to ensure that the culture substrate layer is moist. There is a shallow water layer at the bottom of the trough.

3. Plant management: the plant management of calla is relatively simple, mainly to remove yellow leaves and part of outer leaves, the purpose of peeling off outer leaves is to avoid crowded leaves affecting lighting and ventilation, and pedicels protrude, diseases and insect pests are mainly bacterial soft rot, aphids, red spiders and so on. Bacterial soft rot can harm leaves, petioles and tubers, mainly transmitted by tubers, and can be prevented by spraying Bordeaux solution 500 times at the beginning of the disease.

4. Points for attention

① calla lilies blossom when they grow and require fresh air. Calla lilies are very sensitive to oil fumes and toxic gases, so hydroponic calla lilies should be kept away from the kitchen to avoid smoke pollution. Calla lilies need plenty of sunshine during their growing season, so they should bask in the sun as much as possible in winter.

② should pay attention to ventilation when cultivating calla lilies in water. If the ventilation is poor and the temperature is higher than the natural temperature, it will lead to the harm of powder, aphids, leaf rollers and other pests. If dimethoate is found to be 1500-2000 times, it will be killed.

The essence of hydroponic culture of ③ calla is anoxic cultivation, so zero pollution must be achieved. If the nutrient solution is contaminated by microorganisms, it will consume the amount of dissolved oxygen in the water. Therefore, it is the key to maintain the clean state and inorganic properties of the nutrient solution and the necessary level of dissolved oxygen in the nutrient solution.
