Three principles of hydroponic soilless flower cultivation

Flower soilless cultivation is a new plant cultivation technique in modern times, which can intensively produce a large number of vegetables and fresh cut flowers in a small area, which can not only shorten the production cycle, but also greatly improve the product quality. make the flowers and fruits the same size.

The family uses soilless flower planting, which has many advantages, such as fast growth, good quality, cleanliness, less diseases and insect pests, saving fertilizer, saving water, low labor intensity, saving labor and time, and so on. Now the family soilless flower planting technology is briefly described as follows.

Hydroponic plants: strategies for hydroponic cultivation

1. Scientific planting

Ordinary flowerpots such as plastic pots and vegetable pots can be selected for family soilless pots; when planting, various substrates are mixed in a certain proportion or put separately into pots, and then seedlings with 3-5 leaves are planted in the center of the pots; before planting, put the roots with soil in clean water, gently wash the root mud, and then soak the roots in a solution 5-10 times thinner than the normal concentration of nutrient solution for 10 minutes to fully absorb water. After planting, cover with a layer of quartz sand or pebbles to fix the plant, and immediately pour 0.5 times of the nutrient solution from around the container until there is a nutrient solution flowing out of the drainage hole at the bottom of the basin.

2. Rational nutrition

After planting, water should be watered every 1-3 days and dilute nutrient solution should be watered every 7-10 days; the frequency and number of nutrient solution should be irrigated according to flower species, plant size, different growth stages, seasons and placement location, etc.: during the growth period, the big seedlings should be irrigated with nutrient solution every 7-15 days, the seedlings should be watered once every 15-20 days, and the dormant period should be irrigated once a month. If the flowerpot with an inner diameter of about 20 cm is planted with positive flowers, about 100 ml each time, the negative flowers should be reduced; if long-acting flower fertilizer is used, its dosage should refer to the provisions of the product manual; when pouring nutrient solution, it would rather be less than too much, if it is used too much, it is often easy to cause scorched leaves; generally, thoroughly change the nutrient solution once a month, and wash the container containing the nutrient solution At ordinary times, the amount of nutrient solution in the container is about 2 prime 3 of the depth of the container; if it is filled with too much, the roots are all soaked in the nutrient solution, and the air is insufficient, which is easy to cause rotting roots due to lack of oxygen.

Hydroponic plants: hydroponic flower conservation eight questions and eight answers

Nutrient elements in the flower container will gradually oxidize and photochemical, pH will also be out of balance, should be replaced in time. Indoor flower cultivation 3-4 should be replaced again, and the cultivation substrate must be thoroughly washed with clean water, and then injected with new nutrient solution diluted by adding water, otherwise the concentration of water will be higher and higher.

3. Pay attention to watering

If there is no soil to raise flowers, it is necessary to water them in time according to the water requirements of different kinds of flowers. In order to avoid the loss of nutrient solution, it is best to choose a watertight container. The container which is more suitable for family use consists of two parts, the top is a flowerpot with matrix (the bottom is porous), the flowers are planted into it, and a watertight container is installed below; when using this container, the plant root system should be watered properly before extending into the nutrient solution, and a small amount of dilute nutrient solution should be irrigated every 5-7 days, and the root system should be managed normally after it is extended into the nutrient solution.
