Key points for the maintenance of hydroponic soilless potted flowers

Soilless cultivation can make the plant grow rapidly, robust, blossom more and early, big and fragrant, and resistant to cold and heat, less diseases and insect pests. Generally easy to cultivate flowers are: tortoise back bamboo, Milan, gentleman orchid, camellia, rose, jasmine, rhododendron, kumquat, evergreen, violet, Phalaenopsis, inverted golden bell, five-needle pine, Camptotheca, rubber banyan, Brazilian iron, begonia, ferns, palms and so on. Potted flowers change from soilless cultivation to soilless cultivation, which can be carried out in any season. The specific operation steps are as follows.

I. preparation of nutrient solution

Dilute the soilless culture nutrient solution sold on the market according to the prescribed multiple. You can also use the following formula to prepare your own nutrient solution.

1. A large number of elements: 3 grams each of potassium nitrate and magnesium sulfate, 5 grams of calcium nitrate, 2 grams of ammonium phosphate, 1 gram of potassium sulfate and potassium dihydrogen phosphate.

2. Trace elements: (applied chemical reagent) disodium ethylenediamine tetraacetate 0.1 g, ferrous sulfate 75 mg, boric acid 30 mg, manganese sulfate 20 mg, zinc sulfate 5 mg, copper sulfate 1 mg, ammonium molybdate 2 mg.

3. 5 kilograms of tap water. A large number of elements and trace elements are mixed into solutions, and then mixed to form a nutrient solution. The amount of trace elements is very small, and it is not easy to weigh, so it can be prepared by expanding multiples, and then the amount can be extracted by the same multiple. For example, trace elements can be expanded 100 times to rematch into a solution, and then 1% of the solution can be extracted, that is, the required amount. The nutrient solution is non-toxic, odorless, clean and hygienic, and can be stored for a long time.

2. Take off the basin

Push the root system to the soil with your fingers from the hole at the bottom of the basin.

Third, wash the roots

Soak the roots with soil in water close to the ambient temperature to wash the soil in the rhizosphere.

IV. Immersion solution

Soak the washed root in a mixed nutrient solution for 10 minutes to fully absorb nutrients.

Fifth, filling basin and filling liquid

Wash the flowerpot, place tiles or fill the bottom hole with plastic yarn, then put a little perlite and vermiculite in the pot, then put the plant into the basin and fill the root system with light ores such as perlite and vermiculite. Gently shake the flowerpot to make the ore close to the root system. Immediately irrigate the prepared nutrient solution until there is an outflow from the bottom hole of the basin.

VI. Strengthening the root system

Use quartz stone, axe chopping stone and other pieces on the root system to strengthen the root system and avoid lodging. At the same time, spray some water on the leaves.

VII. Daily management

The requirements of light, temperature and other conditions for the bonsai of soilless cultivation are the same as those of soilless cultivation, the nutrient solution is irrigated once a week during the plant growing period, and the amount of flowers with slow leaf growth is reduced according to the plant size, and once every 30 days in winter or dormant period. Indoor foliage plants can survive in low light, so the amount of nutrient solution should be reduced, and the nutrient solution can also be used for foliar spraying. At ordinary times, we should pay attention to timely watering.
